Tia lives at the corner of 4th street and 8th avenue. lei lives at the corner of 12th street and 20th avenue. the fruit market is three-fourths the distance from tia’s home to lei's home. x = (startfraction m over m n endfraction) (x 2 minus x 1) x 1 y = (startfraction m over m n endfraction) (y 2 minus y 1) y 1 where is the fruit market? 6th street and 11th avenue 10th street and 17th avenue 9th street and 15th avenue 8th street and 14th avenue
Applying the distance formula, the distance from from Tia's home to Lei's home = 14.4 units.
What is the Distance Formula?The distance formula helps us to find the distance between two given coordinate points. It is expressed as, [tex]\mathbf{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} }[/tex].
Tia = (4, 8) = (x1, y1)
Lei = (12, 20) = (x2, y2)
Apply the distance formula to find the distance from Tia's home to Lei's home:
d = √[(12−4)² + (20−8)²]
d = √[(8)² + (12)²]
d = √(64 + 144)
d = √208
d ≈ 14.4 units
The distance from from Tia's home to Lei's home = 14.4 units.

From this we can set up an equation:

[tex]R = \sqrt{\frac{V}{\pi h } } = \sqrt{\frac{16328}{\pi 13} = 19.99493[/tex]
Use the associative property
write an equivalent expression.
(5 + 7) + x =
5+(7+x)
Step-by-step explanation:Finding an Equivalent Expression
The associative property of addition states that you can move the terms that are inside the parentheses and still have the expression remain true. So, in the answer above, I moved 5 out of the parentheses and x into the parentheses. No matter the value of x the value of the expression will remain the same
Examples and Proof
Another example of the associative property could be (1+6)+3 = 1+(6+3). To prove this statement we can evaluate each side of the expression.
First, let's do (1+6)+3
(1+6)+3(7)+310Next, let's do 1+(6+3)
1+(6+3)1+(9)10As you can see both of these expressions are the same, thus proving that the associative property works in this situation.
Please Help! DUE IN 15 MINUTES!! Solutions to Systems. I'll Mark Brainliest!!
Your teacher has given you the system of inequalities below.
5x - 3y > 1
3x + 4y ≤ 18
A fellow student proposes the following method of sketching the solution to the system of inequalities above: "First, I shade the region of points that satisfies the first inequality. Next, I shade the region of points that satisfies the second inequality. The solution consists of all points that have been shaded."
Part A: Do you agree with your peer's method? Explain your answer. Use the system 5x - 3y > 1 and 3x + 4y ≤ 18 to support your answer.
Part B: Include a graph of the system 5x - 3y > 1 and 3x + 4y ≤ 18 to justify your conclusions.
Part C: Label where the solutions are located on the graph.
Answer:
Part A: I disagree, because when shading the regions of inequalities, only the shaded area that overlaps with the other shaded area is the solution, not every single point shaded. 5x - 3y > 1 and 3x + 4y ≤ 18 have an overlapping shaded region, that is where the solutions are.
Part B: picture attached
Part C: All points located on the overlapped shaded region (the darkest part)

The question:
Divide. give the quotient and remainder. 4374/5
(This is from Aleks)
Answer:
Q: 875 R: 4
Step-by-step explanation:
If you dont like doing long division, try plugging values in usling a calculator! Estimate tht 5*8=40, and then, 5*800 must then equal 4000, which is pretty close to 4374
5*7=35, so the 5*70 must equal 350
5*4 equals 20, so when you add these values up you get...
4000+350+20...
or 4370
and, since 4374-4370 equals 4, your remainder would be 4!
This circle is centered at the origin, and the length of its radius is 4. What is the equation of the circle?
Answer:
A. x^2 + y^2 = 4^2
Step-by-step explanation:
The equations of a circle is x^2 + y^2 = r^2
Therefore, the equation of this circle is x^2 +y^2 = 4^2
Answer:
A
Step-by-step explanation:
Remark
The formula for a circle is
x^2 + y^2 = r^2
The number associated with x^2 and y^2 must always be 1. If it's not then you do not have a circle.
Answer
The answer to this question is x^2 + y^2 = 4^2 where r = 4 and it is squared.

if the area of a rectangle is represented by the expression 12x^2-5x-3 and the length is 4x-3, what expression represents the width
Answer:
option C
Step-by-step explanation:
area of rectangle = length * width
12x^2 - 5x - 3 = (4x - 3) * width
12x^2 - 9x + 4x - 3 = (4x - 3)* width
3x(4x - 3) + 1(4x - 3) = (4x - 3)*width
(3x + 1)(4x - 3) / (4x - 3) = width
3x + 1 = width

Answer:105
Step-by-step explanation:
area of rectangle (b*h) (7*12)
Area of triangle 1/2 (b*h) 1/2(7*6)
Rectangle=84
Triangle=21
84+42= 105
Answer:
105
Step-by-step explanation:
Well, this figure, as you can see, is made of two figures - a triangle and a rectangle.
To find it's area we will find the areas of the triangle and the rectangle separately and then sum them. I hope you get why we do that.
So, let's start with the rectangle.
The area of the rectangle is very easy to find simply just multiply the lenghts of its two sides:
A1 = 7 * 12 = 84
Now, the triangle.
You can see that one of the smaller sides of the rectangle is equal to 7. The side in front of it is also 7. Notice that this side is also equal to one of the sides of the triangle, its base.
So from the figure we can tell that the base of the triangle is equal to 7, we are also given its height.
There is a formula we can use here to find the area. The area of a triangle is equal to its base (a) multiplied by the height(h) and divided by 2. I'll call the area of the triangle A2.
We know the height
h = 6
I hope you noticed that we also know the base
a = 7
So we just use the formula:
A2 = (6 * 7) / 2 = 42 / 2 = 21
Now that we have the areas of the two figures, A1 and A2, all we have to do is to sum them to find the area of the big one.
So, let's do it:
A = A1 + A2
A = 84 + 21 = 105
Akira ordered a set of beads. She received 100 beads in all. 8 of the beads were green. What percentage of the beads were green?
Answer:
8%
Step-by-step explanation:
8 out of 100 are green
8/100 * 100% = 8 %
Answer:
8% of the beads are green
Step-by-step explanation:
Step 1: Determine what percentage of the beads are green
This problem is known as a probability problem which basically tries to determine the proportionality between certain numbers. In this example we are trying to figure out the proportionality between the green beads and the total sample.
(8 green beads) / (100 total beads)
0.08
0.08 is the probability but if we want to determine what the percentage is of the number we just multiply it by 100.
0.08 * 100 = 8%
Answer: 8% of the beads are green
Use numerals instead of words. If necessary, use / for the fraction bar

What’s the missing side length in this right triangle?
Answer:
your correct answer is 15
i just did wrong so the person below me is correct
Step-by-step explanation:
Answer:
A: 15
Step-by-step explanation:
It is asking for the hypotenuse of the triangle. To find this, use pythaogreans theorem.
A^2 + B^2 = C^2
In this case,
9*9 + 12*12 = C*C
81 + 144 = C*C
225 = C*C
Now do the square root of both sides and you get
15 = C. Therefore the missing length is 15.

3. What is the probability of choosing a gray button, replacing it, and choosing gray again
Using the binomial distribution, it is found that there is a 0.16 = 16% probability of choosing a gray button, replacing it, and choosing gray again.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are two trials, hence n = 2.Two out of the five buttons are gray, hence p = 2/5 = 0.4.The probability of two gray buttons is:
P(X = 2) = (0.4)² = 0.16.

Answer:
5 feet
Step-by-step explanation:
So you know the cross-sectional area of the circle at the bottom of the cylinder is 28 square feet and you are told the volume of the cylinder is 140 cubic feet which means the height must be 5 feet as the 28 square feet must continue going up to fill the 140 cubic feet.

2x + y = 7, y is a function of x

It is a linear equation (straight line)The vertical line touches the graph only one time. Thus y is a function of x.
Answer:
Given equation: [tex]2x+y=7[/tex]
Definition of a function
A relation is a function if each y-value corresponds to one or more x-values.A relation is not a function if each x-value corresponds to more than one y-value.The given function is in the standard form of a linear equation: [tex]ax+by=c[/tex]
If the given equation is rearranged to make y the subject:
[tex]y=-2x+7[/tex]
it is now in the general form of a linear equation, [tex]y=mx+b[/tex] (where m is the slope and b is the y-intercept).
A linear equation is one of a straight line, and so, by definition, each value of y corresponds to one value of x. Therefore, this is a one-to-one function.
