Step-by-step explanation:
given a storm has a destruction area in the shape of a square, give the total area affected if the side lengths of the square were 315.2
Answer:
to find area, multiply the two sides together. since it tells us that this is a square we can assume both sides are the same length (315.2). multiply 315.2 and 315.2, and you get 99,351.04.

Compare the ratios. Is Celeste using the correct ratio of apples to oranges?
The ratio for the first table is 5/6.
The ratio for the second table is 2/3.
Yes, Celeste is using the correct ratio of apples to oranges.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
From the first table,
The ratios of apples and oranges.
- 5/6
- 10/12 = 2x5/2x6 = 5/6
- 15/18 = 3x5/3x6 = 5/6
- 20/24 = 4x5/4x6 = 5/6
From the second table,
The ratios of apples and oranges.
- 2/3
- 4/6 = 2x2/2x3 = 2/3
- 6/9 = 3x2/3x3 = 2/3
- 8/12 = 2x4/3x4 = 2/3
Thus,
The ratio for the first table is 5/6.
The ratio for the second table is 2/3.

1. It is not proportional because if it is going up 36 every time, number 5 should be 180.
2. The difference between 3 and 7 cans of red bull are $10. 4 cans are $10. Each can is 2.50.
Step-by-step explanation:
Answer:
a. The relationship is NOT proportional
b. The constant of proportionality is 0.4
Step-by-step explanation:
a. The numbers in the table are not proportional. We can tell that by dividing the top numbers by the bottom numbers they're matched with to find and compare ratios. 2/72=0.0277, but 8/296=0.0270, so since they're not equal, they're not proportional.
b. We find the constant of proportionality by doing the same thing as we did to find the ratios above. So 3/7.50= 0.4. To make sure the rate is the same, we'll also check that 7/17.50=0.4. Since it does, we know that that's the answer.

Answer:
Just to help you out in how to solve this just plug in every x of an equation -6, and in every y, -1. Plug these two number in every equation and see if it equal each other.Example:
y =4x +23
-1 = 4(-6) + 23
-1 = -24 + 23
-1 = -1
it shows that (-6,-1) is a solution to this equation

Copy the proof on paper, mark the givens in the diagram, and fill in the blanks to complete the proof.
This is the actual answer:
The missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.
What is congruence in the triangles?The measurements of the sides and angles of two or more triangles determine their congruence. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of corresponding sides and angles of two triangles are equal, they are said to be congruent.
We have:
As we can see in the diagram,
First, we will draw PU
PU is the common side for both the triangles
PU ≅ PU (reflexive property)
UO ≅ UR (given)
PO ≅ PR (given)
By the property of SIde-Side-Side
The triangle OUP ≅ Triangle RUP
By Corresponding parts of congruent triangles are congruent:
Angle O ≅ Angle R (proved)
Thus, the missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.
