An investment company is offering you two different policies.
a. Invest $1000, and it will grow by 10% per year.
b. Invest $3000, and it will grow by $150 per year.
Which investment is worth more after 1 year? Explain how
Investment a grows faster than investment b, and thus investment b is the better choice.
We can calculate the worth of each investment after 1 year by applying the given rates of growth.
a. For investment a, the initial investment of $1000 grows by 10% per year. Therefore, the worth of the investment after 1 year is:
1000 + 0.1*1000 = $1100
b. For investment b, the initial investment of $3000 grows by $150 per year. Therefore, the worth of the investment after 1 year is:
3000 + 150 = $3150
Comparing the two worths, we see that investment b worth more after 1 year, since $3150 is greater than $1100. Therefore, investment b is the better choice.
Alternatively, we can also calculate the growth rates of each investment and compare them directly. For investment a, the growth rate is 10% = 0.1, whereas for investment b, the growth rate is 150/3000 = 0.05 or 5%. Since 0.1 > 0.05, we can again conclude that investment a grows faster than investment b, and thus investment b is the better choice.

Label the measures of all of the angles on the picture
below.
Remember that, if you know one angle is 64°, you can use
this to help you figure out the measure of all of the other
angles.
Answer:
6, 2, and 3 would all also be 64° angles. 1, 4, 5, and 8 would all be 116° angles.
Step-by-step explanation:
Since 64° and 5 make up a supplementary angle (180°) just do the equation 180°-64° to get 116°. From there know that 64° and angle 6 must be equal (using the same logic from supplementary angles) then angles 2 and 3 must also be equal. Then apply that to angle 5 (which is 116°) and angle 8, as well as angles 1 and 4.

In the word problem , Chris takes 40 ml of 20% alcohol and 160 ml of 60% alcohol.
What is percentage?
Divide the A value or ratio that may be stated as a fraction of 100 is referred to in mathematics as a number by the total and multiply by 100 to find the percent of a given number. Therefore, the percentage refers to a portion per hundred. Per 100 is what the word percentage signifies. The letter "%" stands for it.
Let the volume of 20% solution be x
Then volume of 60% solution is 200 - x
Alcohol in 20% solution = 0.2*x = 0.2x
Alcohol in 60% sol = 0.6(200-x) = 120 - 0.6 x
If the final solution is of 52% concentration, it means the volume of alcohol in it
= 200*0.52 = 104 ml
So we have the equation
=> 0.2x + 120 -0.6x = 104
=> 120-104 = 0.4x
=> 0.4x = 16
=> x = 40 ml
So he takes 40 ml of 20% alcohol and 160 ml of 60% alcohol.

The smallest number of eggs that could have been in the basket = 301
Given that the basket is filled with an unknown number of eggs.
Let N be the smallest number of eggs in the basket.
When eggs are removed 2, 3, 4, 5, or 6 at a time, one egg is left over at the end which means (N-1) is divisible by 2, 3, 4, 5, or 6, i.e. (N-1) is the least common multiple of 2, 3, 4, 5, and 6.
Since LCM (2, 3, 4, 5, 6) = 60
So, (N-1) should be a multiple of 60, then only (N-1) will be divisible by 2, 3, 4, 5, and 6. Therefore N is of the form 60k+1 (where k is an integer).
Since no egg is left over when they are removed 7 at a time, N should be a multiple of 7. Smallest multiple of 7 that is of the form 60k+1 (where k is an integer) is 301.

what is area of circle?
The area of a circle is given by the formula,where A is the area of the circle, r is the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14159.In words, the area of a circle is equal to pi times the square of its radius.
In the given question,
The area of a sector of a circle is given by the formula:
A = (θ/360) * πr²
where:
θ is the angle at the center of the circle (in degrees)
r is the radius of the circle
π is the mathematical constant pi (approximately equal to 3.14)
In this case, the angle at the vertex of the sector piece is 60 degrees, and the radius is 9 cm. Therefore, the area of the sector piece is:
A = (60/360) * π * 9²
A = (1/6) * π * 81
A = 13.5π
A ≈ 42.4115 cm²
So the area of the sector piece is approximately 42.4115 square centimeters
A = π(8.4 cm)²
A = 221.76 cm²
Next, we need to find the fraction of the circle that corresponds to the given angle. The total angle of a circle is 360 degrees, so the fraction of the circle that corresponds to an angle θ in degrees is:
f = θ/360
Plugging in the given angle of 242 degrees, we have:
f = 242/360
f = 0.6722
So the area of the sector piece is:
A_sector = f * A
A_sector = 0.6722 * 221.76 cm²
A_sector = 149.03 cm²
Therefore, the area of the sector piece is approximately 149.03 cm².

Mr. Nelson is taking his students on a field trip to an observatory. The Observatory charges a $100 trip fee, plus $6.50 per student. If Mr. Nelson spent $327.50, how many students did he take on the trip?
Answer: 35
Step-by-step explanation:
Let's assume that Mr. Nelson took "x" students on the trip.
According to the problem, the observatory charges a trip fee of $100, which Mr. Nelson had to pay regardless of how many students he took.
In addition to that, he also had to pay $6.50 per student. So the total cost of the trip can be expressed as:
Total cost = $100 + ($6.50 * number of students)
We know from the problem that the total cost of the trip was $327.50. So we can set up an equation:
$327.50 = $100 + ($6.50 * x)
Now we can solve for "x" by first subtracting $100 from both sides:
$327.50 - $100 = $6.50x
$227.50 = $6.50x
Finally, we can solve for "x" by dividing both sides by $6.50:
x = $227.50 ÷ $6.50
x ≈ 35
Therefore, Mr. Nelson took approximately 35 students on the field trip.

What is area?In geometry, area refers to the measure of the size of a two-dimensional surface or region. It is typically expressed in square units, such as square meters, square feet, or square centimeters.
To find the area of a shape, you need to measure the length and width of the shape and then multiply those measurements together. The formula for calculating the area of a rectangle, for example, is length x width. The formula for calculating the area of a circle is pi x radius squared, where pi is a mathematical constant, and the radius is the distance from the center of the circle to its edge.
by the question.
sure, I can help you with that!
To find the area of the composite figure, we need to find the area of each individual shape and then add them up.
First, let's find the area of the sector of the circle. We know that the radius of the circle is 6 cm, and the central angle of the sector is 82% of a full circle. Since a full circle has 360 degrees, we can find the central angle of the sector by multiplying 360 by 0.82:
[tex]Central angle of sector = 360 x 0.82 = 295.2 degrees[/tex]
The area of the sector can be found using the formula:
Area of sector = (central angle/360) x π x radius^2
Substituting the values, we know:
[tex]Area of sector = (295.2/360) x 3.14 x 6^2 = 56.57 cm^2[/tex]
Next, let's find the area of the triangle. We know that the base of the triangle is 8 cm, and the height is 10 cm. We can use the formula for the area of a triangle:
[tex]Area of triangle = 1/2 x base x height[/tex]
Substituting the values, we know:
[tex]Area of triangle = 1/2 x 8 x 10 = 40 cm^2[/tex]
Now, we can add the areas of the sector and the triangle to find the total area of the composite figure:
Total area = area of sector + area of triangle
[tex]Total area = 56.57 + 40 = 96.57 cm^2[/tex]
Rounding this to the nearest hundredth, we get:

what is the probability he gets exactly one rose given that at least one of the flowers he gets is pink
The probability that he gets exactly one rose given that at least one of the flowers he gets is pink is 4/7.
To calculate the probability that he gets exactly one rose given that at least one of the flowers he gets is pink, we need to use conditional probability. Let R be the event that he gets a rose and P be the event that he gets a pink flower. Then, we want to find P(R=1 | P≥1).
Using Bayes' theorem, we have:
P(R=1 | P≥1) = P(R=1 and P≥1) / P(P≥1)
We can calculate the probability of getting at least one pink flower as:
P(P≥1) = 1 - P(P=0)
Assuming the probabilities of getting a rose and a pink flower are independent, we can calculate the probabilities of getting exactly one rose and at least one pink flower as:
P(R=1 and P≥1) = P(R=1) * P(P≥1) = (2/5) * (1 - 3/5) = 2/5 * 2/5 = 4/25
P(P=0) = 3/5, since there are 3 flowers that are not pink out of a total of 5.
Therefore, we have:
P(R=1 | P≥1) = (4/25) / (1 - 3/5) = 4/7
So the probability that he gets exactly one rose given that at least one of the flowers he gets is pink is 4/7.

Determine whether these lines are parallel, perpendicular, or neither. y = 3x -x-3y = 4
We can conclude that the lines are perpendicular, the slopes are negative reciprocals of each other,
What are the slopes?
To determine if the lines are parallel or perpendicular, we need to put both equations in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
y = 3x -x
-3y = -x + 4 (divide both sides by -3)
y = (1/3)x - (4/3)
Now we can see that the slope of the first equation is 3, and the slope of the second equation is (1/3). If two lines are perpendicular, their slopes are negative reciprocals of each other, meaning that one slope is the negative inverse of the other. The negative reciprocal of 3 is -1/3, and the negative reciprocal of 1/3 is -3. Since the slopes are negative reciprocals of each other, we can conclude that the lines are perpendicular.
The slope of a line can be positive, negative, zero or undefined. A positive slope indicates that the line is slanting upward from left to right, while a negative slope indicates that the line is slanting downward from left to right. A slope of zero indicates that the line is horizontal, while an undefined slope indicates that the line is vertical.

What are the following is equal to the square root of 18 X to the seventh power Y to the sixth power
the answer to the question is 5.20XY cubed.
How to solve the problem?
The square root of 18 X to the seventh power Y to the sixth power can be simplified using the laws of exponents and radicals. First, we can express 18 as a product of its prime factors: 18 = 2 x 3 x 3. Then, we can write X to the seventh power as X to the sixth power times X, and Y to the sixth power as Y to the third power squared.
So, we have:
Square root of 18 X to the seventh power Y to the sixth power
= Square root of (2 x 3 x 3) X to the sixth power X Y to the third power squared
= Square root of 2 X to the sixth power Y to the third power squared times 3
= Square root of 2 X to the sixth power Y to the third power squared times square root of 3
Using the laws of exponents and radicals, we can simplify the square root of 2 X to the sixth power Y to the third power squared as X cubed Y cubed, and we can approximate the square root of 3 as 1.73. Therefore:
Square root of 18 X to the seventh power Y to the sixth power
= X cubed Y cubed times square root of 3
= 3XY cubed times 1.73
= 5.20XY cubed (rounded to two decimal places)
So, the answer to the question is 5.20XY cubed.

a. To rationalize the expression √√√4 + x = 3 3, we need to get rid of the cube roots in the denominator.
First, we simplify the cube root of 4:
√√√4 = √√2
So, our expression becomes:
√√2 + x = 3 3
To get rid of the cube root in the denominator, we need to multiply both sides by the conjugate of the denominator:
(3 - √2)(√√2 + x) = 3
Expanding the left side:
3√√2 + 3x - 2√2 - √2√√2x = 3
Simplifying:
3x - 2√2 - √2√√2x = 3 - 3√√2
Combining like terms:
(3 - √2)x = 3 - 3√√2 + 2√2
Simplifying:
(3 - √2)x = (3 + 2√2) - 3√√2
Dividing both sides by (3 - √2):
x = [(3 + 2√2) - 3√√2]/(3 - √2)
Simplifying:
x = (3 + 2√2)(3 + √2)/7
b. To rationalize and solve for x in the expression 1-√2:
We need to get rid of the radical in the denominator by multiplying both the numerator and denominator by its conjugate:
1 - √2 / 1 - √2 * 1 + √2 / 1 + √2
Simplifying, we get:
(1 - √2)(1 + √2) / (1 - √2)(1 + √2)
= 1 - 2
= -1
So, x = -1.
Therefore, the rationalized expressions are:
a. √√2 + x = (3 + 2√2)(3 + √2)/7
b. 1-√2 = -1

what is circle ?A circle is a geometric shape made up of all points in a plane that are equally spaced apart from a specific point known as the circle's center. The diameter of a circle is the distance through its center; the radius of the circle is the distance from any point on the circle to that point. A circle's circumference, which is measured around it, is equal to either two times the radius or one time the diameter. Several branches of mathematics, science, and engineering make use of circles.

An image of a rectangle of twenty-eight feet in length and sixteen feet in width. A rectangle is highlighted at fourteen feet long and eight feet wide. A right-angle triangle is formed below the rectangle. Text reads: reserved section and lawn.
The city mayor wants to use the reserved section of a rectangular park for gardening lessons conducted by the city public school. The rest of the park will be turned into a lawn. What will the area of the lawn be?
A.
168 square feet
B.
224 square feet
C.
280 square feet
D.
448 square feet
The 280 square foot lawn is in the designated area of a rectangular park that the city mayor wishes to use for gardening.
By area, what do you mean?An object's area is how much space it takes up in two-dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
The square-unit, which is frequently expressed as square inches, square feet, etc., is the accepted unit of area.
The rectangular park's allocated area is intended to be used by the city's public school for gardening courses.
The remaining area of the park will be developed into a lawn.
What is the lawn's formula?
The lawn's area is equal to the sum of its triangular and rectangle areas.
Lawn Area = 14 × 16 +.5 × 8 × 14
A = 224 + 56
A = 280 Ft²
Therefore, the correct option is 280ft² which is option C.
