Answer:
Step-by-step explanation:
If [tex]A =\pi xy[/tex], then π, x, and y are all multiplied together. Multiplication is undone by division, so we will divide away the πx to solve for y:
[tex]\frac{A}{\pi x}=y[/tex] which is your last option.
Here, we are required to find an equivalent equation solved for y if the area, a is given by;
a = πxy
An equivalent equation solved for y is;
y = a ÷ (πx)
To find an equivalent equation solved for y,
We have to make y the subject of the formula in;
a = πxy.
Therefore, by dividing both sides of the equation by πx, so that y is left alone on the right hand side.
Therefore, y = a ÷ (πx).

__________________________________Explanation:We already know that the formula for area of a rectangle is A = l × w.
Notice how the width and the length are being multiplied to find the area.
Well, to find the width, we must do the opposite of multiplication, which is division.
Since we already have the length, all we have to do is divide the area by the length for each of the questions.
1:
A = l × w
55.5 = 9.25 × w
[tex]\frac{55.5}{9.25}[/tex] = 6
2:
A = l × w
48.75 = 7.5 × w
[tex]\frac{48.75}{7.5}[/tex] = 6.5
3:
A = l × w
44 = 5 × w
[tex]\frac{44}{5}[/tex] = 8.8
4:
A = l × w
31.25 = 5 × w
[tex]\frac{31.25}{5}[/tex] = 6.25

Dora says that of all the possible rectangles with the same area, the rectangle with the largest perimeter will have two side lengths that are 1 unit does her sentment make sense?
Answer:
maybe
Step-by-step explanation:
Dora is apparently assuming the dimensions are integers. In that case she is correct.
If the dimensions are unconstrained, the perimeter will be largest when a pair of opposite sides will be the smallest measure allowed.
For some perimeter P and side length x, the area is ...
A = x(P/2 -x)
Conversely, the perimeter for a given area is ...
P = 2(A/x +x)
This gets very large when x gets very small, so Dora is correct in saying that the side lengths that are as small as they can be will result in the largest perimeter. We have no way of telling if her assumption of integer side lengths is appropriate. If it is not, her statement makes no sense.

What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Angles are usually measured in degrees or radians.
The angle mentioned in the figure is at the point S.
This angle is the smaller angle formed at the point S.
An angle can be represented in two ways, from left to right or from right to left.
Suppose, an angle is ∠ABC.
We can represent this as ∠CBA.
So, the angle represented is ∠TSU.
Hence the angle is ∠TSU.

5x + 2y = 34
x= - 4y - 4
Answer:
y = -3
Step-by-step explanation:
So, first you need to plug in -4y-4 for x. So, 5(-4y-4) + 2y=34. Now, use the distributive property and now it will become -20y -20 + 2y = 34. Add like terms which would be -20y + 2y = -18y. Now the equation is -18y - 20 = 34. Now use inverse operations and add 20 to both sides. Then the equation will be -18y = 54. When you divide -18 on both sides, you get y=-3.
Hope this helps :)
The best player on a basketball team makes 70% of all free throws. The second-best player makes 65% of all free throws. The third-best player makes 55% of all free throws. Based on their experimental probabilities, estimate the number of free throws each player will make in his or her next 60 attempts. Explain.
If the best player makes 70% of all free throws, then this player would be expected to make 70% of the next 60 free throws, which is 42. (The equation that goes with this is [tex]\frac{70}{100}=\frac{x}{60}.[/tex])
Similarly, the second-best player would make 65% of 60 throws, which is 39, and the third-best player would make 55% of 60 throws, which is 33.

Triangle triangle A^ prime B^ prime C^ prime is the image of triangle ABC under a dilation What is the scale factor of the dilation
Answer:
2
Step-by-step explanation:
The scale factor of the dilation of triangle ABC into the triangle A^ prime B^ prime C^ prime is 2.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure. Scale factor is the ratio of representation measurement of the figure to the original figures.
Triangle A^ prime B^ prime C^ prime is the image of triangle ABC under a dilation.
The height of the triangle ABC is 5 units (blocks) and the height of the dilated triangle A'B'C' is 10 units. Thus, the scale factor is,
[tex]k=\dfrac{10}{5}\\k=2[/tex]
Hence, the scale factor of the dilation of triangle ABC into the triangle A^ prime B^ prime C^ prime is 2.

The mean temperature for the first 7 days in January was 6 °C. The temperature on the 8th day was 10 °C. What is the mean temperature for the first 8 days in January?
Answer:
6.5
Step-by-step explanation:
In this question, we are tasked with calculating the mean temperature for the first 8 days.
since we we have the mean temperature for the first 7 days, the total temperature is thus 7 * 6 = 42
Now, on the 8th day, temperature is 10, this brings total temperature to 42 + 10 = 52
The mean temperature for the first 8 days ys therefore; 52/8 = 6.5

En el supermercado pusieron las siguientes ofertas d frijol : 4kg a 100.80, 5kg a 170.50, 6kg a 260.60, 7kg a 320.40. ¿Cuál es la oferta que más conviene comprar? Explica tu respuesta:
Answer:
The first offer: 100.80 for 4kg
Step-by-step explanation:
To find the best offer, we just need to find the price per kilogram, and we do this by dividing the price by the number of kg:
100.80 for 4kg: 100.8/4 = 25.2 per kg
170.50 for 5kg: 170.5/5 = 34.1 per kg
260.60 for 6kg: 260.6/6 = 43.43 per kg
320.40 for 7kg: 320.4/7 = 45.77 per kg
The first offer has the smaller price per kg, so it is the best offer.

A student is doing a reading assignment. After 41 minutes of reading, she skims the pages ahead and estimates that she still has 53% of the reading to do. According to the girl's estimate, how long is the total reading assignment? Round to the nearest minute.
Answer:
Approximately 87 minutes
Step-by-step explanation:
So first see how much of the reading 41 minutes is. It is 47%.
So now to find out how much 100% is, first find out how much 1% is.
Just divide by 47.
1% = [tex]\frac{41}{47}[/tex]
And then multiply by 100 to get 100%

Triangle ABC has two known angles. Angle A measures 55 degrees. Angle B measures 30 degrees. What is the measure of angle C? Show your work and explain how to solve.
Answer:
According to triangle theorems, we know that the interior angles of a triangle equals 180 degrees. Since we know that angle A and angle B are 55 and 30 degrees, all we need to do is add them up and subtract it from 180 degrees to find out the measure of angle C.
55 + 30 = 85 degrees
180 degrees - 85 degrees = 95 degrees (this is the measure for angle C)
The m∠C in the triangle is 95° as the other two angles are 55° and 30°
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of all the interior angles in a triangle is 180°.
Given, In a triangle, m∠A is 55° and m∠B 30°.
Therefore m∠C = 180° - 55° - 30°.
m∠C = 95°.
