Answer:
x=7
Step-by-step explanation:
The equation can be represented as following:
[tex](\frac{x}{14} +3\frac{1}{2})=2(\frac{x}{21} +1\frac{2}{3})[/tex]. If we open the parenthesis, we can get as following:
[tex]\frac{1}{14}x +3\frac{1}{2}=\frac{2}{21}x +3\frac{1}{3} \\[/tex], which then subtract [tex]2\frac{2}{21} x[/tex] from both sides to get the following:
[tex]\frac{7}{2}-\frac{1}{42} x=\frac{10}{3}[/tex];
subtract [tex]\frac{7}{2}[/tex] from both sides to get [tex]\frac{-1}{42} x=\frac{-1}{6}[/tex], and multiply both sides by -42 to get our final answer of x=7

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochet at a rate of 1/15 of a blanket per day. She has 60 days until she wants to donate the blankets, but she also wants to skip crocheting some day so she can volunteer in other ways. Write and solve an inequality for how many days she can skip and still finish the blankets.
Answers
If Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie can skip up to 15 days and still finish crocheting at least 3 blankets before she wants to donate them to the homeless shelter.
How many days she can skip and still finish the blankets?Let's first calculate how much of a blanket Darcie can crochet in 60 days if she works every day:
1/15 blanket per day * 60 days = 4 blankets
Since Darcie wants to crochet a minimum of 3 blankets, we know that she needs to work for at least 3/4 of 60 days. Let x be the number of days Darcie can skip and still finish the blankets:
(60 - x) * 1/15 >= 3
Simplifying this inequality, we get:
4 - 1/15x >= 3
1/15x <= 1
x <= 15
Therefore, Darcie can skip up to 15 days and still finish crocheting at least 3 blankets before she wants to donate them to the homeless shelter.

from a point 100m from a building the angles of elevation to the top and the bottom of a flagpole atop the building are 54.5 degrees and 51.8 degrees. how tall is the flagpole?
Answers
From a point 100m from a building the angles of elevation to the top and the bottom of a flagpole atop the building are 54.5 degrees and 51.8 degrees. Therefore, the height of the flagpole is 125.6m.
we can use the trigonometric ratios of Sine, Cosine, and Tangent.
First, we need to draw a right triangle with the given information.
The triangle will have two sides:
the 100m side and the side to the flagpole. We can use the angle of elevation of 54.5 degrees to calculate the side of the triangle opposite the flagpole.
To do this, we use the Tangent ratio and solve for the side opposite the flagpole (the height of the flagpole):
Tangent(54.5) = Height/100
Height = 100*Tangent(54.5)
Height = 100*1.256
Height = 125.6m

Write each expression as a product.
(a+1)^3+x^3
Answers
We can write this expression as a product of two factors:
(a + 1)³ + x³ = (a + x + 1)(a²- a x + x² + x + a + 1)
HOW TO WRITE expression as a product.?
To write an expression as a product means to represent the expression as the multiplication of two or more factors. The process of writing an expression as a product depends on the type of expression and the algebraic techniques that are available.
Here are some general steps that can be followed to write an expression as a product:
Look for common factors: If there are common factors in the expression, they can be factored out using the distributive property. For example, in the expression 3x + 6, we can factor out 3 to get 3(x + 2).
Use algebraic identities: There are many algebraic identities that can be used to factor expressions. For example, the difference of squares identity (a² - b²= (a + b)(a - b)) can be used to factor expressions that are in the form of a difference of squares.
Look for patterns: Sometimes, expressions can be factored by recognizing patterns. For example, the expression x² + 2x + 1 can be factored as (x + 1)²by recognizing that it is a perfect square trinomial.
Use polynomial division: If the expression is a polynomial with higher degree, polynomial division can be used to factor it into linear and quadratic factors.
Use the quadratic formula: If the expression is a quadratic trinomial that cannot be factored easily, the quadratic formula can be used to find the roots of the equation, which can then be used to write the expression as a product of linear factors.
Overall, writing an expression as a product requires a good understanding of algebraic techniques and a lot of practice.
We can use the formula for the sum of cubes to write the expression as a product:
(a + 1) + x³ = (a + 1 + x)(a² - a x + x²) + x³
Expanding the first factor on the right-hand side using the distributive property, we get:
(a + 1 + x)(a²- a x + x²) + x^3 = a³- a² x + a x² + a² + a x + x²+ x³
Collecting like terms, we can write this expression as a product of two factors:
(a + 1)³ + x³ = (a + x + 1)(a²- a x + x² + x + a + 1)

The range of the function is the set of all possible output values, which are {2, 6, 8, 10}. So the correct answer is option C.
Describe Function?In mathematics, a function is a rule that assigns each element of a set (called the domain) to a unique element of another set (called the range). Functions are a fundamental concept in mathematics and are used to describe relationships between variables, as well as to model and solve a wide range of mathematical problems.
A function is typically denoted using a letter such as "f", and is defined by an equation or formula that specifies how the input (or domain) values are transformed into output (or range) values. For example, the function "f(x) = 2x + 1" assigns each input value "x" to an output value equal to twice the input value plus one.
To find the range of the function f(x) = x + 3, we need to apply the function to each value in the given domain and collect the resulting outputs.
When the domain is {-1, 3, 5, 7}, we have:
f(-1) = -1 + 3 = 2
f(3) = 3 + 3 = 6
f(5) = 5 + 3 = 8
f(7) = 7 + 3 = 10
Therefore, the range of the function is the set of all possible output values, which are {2, 6, 8, 10}. So the correct answer is option C.

in testing a certain kind of truck tire over rugged terrain, it is found that 25% of the trucks fail to complete the test run without a blowout. of the next 15 trucks tested, find the probability that
Answers
We have that, when testing a certain type of truck tire on rough terrain, it is observed that 25% of the trucks fail to complete the test without blowout, the probability that of the next 15 trucks tested, at least one will not able to complete the test run without an explosion is 0.987
How do we calculate the probability?Given that when testing a certain type of truck tire on rough terrain, it is found that 25% of the trucks do not complete the test without blowout.So, the probability that a truck completes the test without a blowout is:
P (A complete truck test without blowout) = 1 - P (A complete truck test without an explosion) = 1 - 0.25 = 0.75
Now, we need to find the probability that of the next 15 trucks tested, at least one will not complete the test without an explosion. This can be found using the complement rule. The complement of the probability that at least one truck does not complete the test without a blowout is the probability that all 15 trucks complete the test without a blowout.
P(All 15 trucks complete the test without a blowout) = P(One truck completes the test without a blowout) x P(A second truck completes the test without a blowout) x ... x P(The fifteenth truck completes the test without a blowout) = 0.75 x 0.75 x ... x 0.75 (15 times)= 0.75^15= 0.013
But we need the probability that at least one truck fails to complete the test without a blowout, which is the complement of the above probability.
P(At least one truck does not complete the test without blowout) = 1 - P(All 15 trucks complete the test without blowout)= 1 - 0.013= 0.987
Therefore, the probability that of the next 15 trucks tested, at least one will not be able to complete the test run without an explosion is 0.987.

She still has 40 pages to read in her final book before the competition if she reads five times number of pages tonight as she read last night and then the last 10 pages tomorrow night she will be finished with her book right and solve an equation to determine how many pages Brinsey has to read tonight
Answers
Answer: 25
Step-by-step explanation:
Let x represent the number of pages Broonzy read last night. Then, 5x represents the number of pages she will read tonight. According to her plan, after reading 5x pages tonight and 10 pages tomorrow night, she will complete the remaining 40 pages. The equation can be expressed as:
x (last night) + 5x (tonight) + 10 (tomorrow night) = 40 (total remaining pages)
Combining the terms, we get:
6x + 10 = 40
Now, let's solve for x:
6x = 30
x = 5
So, Broonzy read 5 pages last night. To determine the number of pages she needs to read tonight, we multiply x by 5:
5x = 5 * 5 = 25
Therefore, Broonzy has to read 25 pages tonight to finish her book according to her plan.

Applying the Pythagorean Theorem In this activity, you will explain your understanding of mathematical relationships and use the Pythagorean theorem to solve real-world problems. Question 1 In your own words, explain the relationship between the legs and the hypotenuse of a right triangle.
Answers
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse = sum of the squares of the legs.
What is the Pythagorean theorem?
The Pythagorean theorem that relates to the sides of a triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides (known as the legs). Mathematically, it can be expressed as a² + b² = c², where "a" and "b" are the lengths of the legs, and "c" is the length of the hypotenuse.
Now,
In a right triangle, the legs are the two sides that form the right angle, and the hypotenuse is the side that is opposite to the right angle. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse = sum of the squares of the legs. So, the relationship between the legs and the hypotenuse can be described by this theorem. In other words, if we know the length of the two legs of a right triangle, we can use the Pythagorean theorem to find the length of the hypotenuse, and vice versa. The hypotenuse is always the longest side of the right triangle, and it is also the side that connects the two legs.

When examining the plots, only one displays a straight line going from -17 to -5 and a ray going from -13 to -5. (indicating that x can be any value greater than or equal to -13) Thus, option C is correct.
What is the inequality?To solve the inequality, we can simplify it by first distributing the -1/4 on the left side:
[tex]-3x - 2 ≤ -2x + 11[/tex]
Next, we can isolate the variable on one side by subtracting -2x from both sides:
[tex]-x - 2 ≤ 11[/tex]
Finally, we can isolate the variable by adding 2 to both sides:
[tex]-x ≤ 13[/tex]
And since we want to solve for x, we need to multiply both sides by -1, which will flip the direction of the inequality:
[tex]x ≥ -13[/tex]
This means that x can be any value greater than or equal to [tex]-13[/tex] .
Therefore, Looking at the graphs, the only one that shows a straight line passing from -17 to -5 and a ray starting at -13 and passing through -5 (indicating that x can be any value greater than or equal to -13)

A) 3.2 x (8 ÷ 4) + 10 = 3.2 x 2 + 10 = 6.4 + 10 = 16.4 (not equal to 14.8)
B) 4.6 + (6 ÷ 2) x 2 = 4.6 + 6 = 10.6 (not equal to 14.8)
C) 6.4 + (10 − 3) + 4 = 6.4 + 7 + 4 = 17.4 (not equal to 14.8)
D) 7.8 x (12 ÷ 6) − 0.8 = 7.8 x 2 - 0.8 = 15.6 - 0.8 = 14.8
Therefore, the expression that makes the equation true is:
7.8 x (12 ÷ 6) − 0.8
The temperature, T (in degrees Kelvin), of an enclosed gas varies
jointly with the product of the volume, V (in cubic centimeters), and
the pressure, P (in kilograms per square centimeter). The temperature
of a gas is 294 degrees K when the volume is 8000 cubic centimeters and the
pressure is 0.75 kilogram per square centimeter. What is the
temperature when the volume is 7000 cubic centimeters and the
pressure is 0.87 kilogram per square centimeter?
Answers
Answer: 298.41 K
Step-by-step explanation:
given from the problem: T=VPC
where C is a constant
plug in knowns to get C
294= (8000)(0.75)C
C=0.049
T=VP(0.049)
T = (7000)(0.87)(0.049)
T = 298.41 K

After answering the provided question, we can conclude that As a result, equation the cost of 2 pounds of candy is $7.00.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "[tex]2x + 3 = 9"[/tex] asserts that the statement "[tex]2x + 3[/tex]" equals the value "9". The goal of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complex, regular or nonlinear, and include one or more factors. In the equation "[tex]x2 + 2x - 3 = 0[/tex]," for example, the variable x is raised to the second power. Lines are used in many different areas of mathematics, such as algebra, calculus, and geometry.
Claim: To calculate the cost of 2 pounds of candy, multiply the cost per pound of candy by 2.
According to the data provided, the cost per pound of candy is $3.50.
Reasoning: In order to determine the cost of 2 pounds of candy, we must first determine the total cost of 2 pounds of candy. Because the price per pound of candy is $3.50, we can calculate the total cost by multiplying the price per pound by the number of pounds. In this case, we want to know how much it costs for two pounds, so we multiply $3.50 by two to get:
2 pounds of candy = $3.50 per pound x 2 pounds = $7.00
As a result, the cost of 2 pounds of candy is $7.00.

6. Keela was making a flag of Ireland for St. Patrick's Day. She knew that the flag was exactly twice
as long as it was tall and that there were three equally sized vertical bars in green, white and orange
(from left to right). She used 9" x 12" construction paper to make her flag. The width of the green
bar was exactly two short sides of the construction paper across minus a overlap. What were the
dimensions of the final flag and how many pieces of construction paper did it take?
hat only had
Answers
The dimensions of the final flag and the number of pieces of construction paper it took would be 9 inches tall and 18 inches long.
Three (3) pieces of 9" x 12" construction paper are needed.
How to find the dimensions of the flagFirst, let's find out the dimensions of the flag. The flag is twice as long as it is tall. If the height of the flag is H, then the length L would be 2H.
Since there are three equally sized vertical bars, the length of the flag would be 3 times the width of the green bar:
L = 3(18 - a)
Now, we know that L = 2H. So,
2H = 3(18 - a)
Given that the construction paper is 9" x 12", we can try to create the flag with the minimum amount of overlap a. Since the height of the flag should be equal to the short side of the construction paper, H = 9 inches.
Now we can plug in the value of H in the equation we derived above:
2(9) = 3(18 - a)
18 = 54 - 3a
3a = 36
a = 12
Now we can calculate the dimensions of the final flag:
H = 9 inches
L = 2H = 2(9) = 18 inches
