Answer:
The answer to your question is ratio = 9
Step-by-step explanation:
Data
Circle 1 radius = 5''
Circle 2 radius = 15''
Process
1.- Calculate the area of circle 1
Area = πr²
Area = π(5)²
Area = 25π
2.- Calculate the area of circle 2
Area = πr²
Area = π(15)²
Area = 225π
3.- Calculate the ratio of the areas
ratio = 225π / 25π
= 9
Answer: When you reflect a point across the x-axis the x-coordinate remains the same, but the y-coordinate is transformed into its opposite
Step-by-step explanation:
Answer:
x=−3y−15
Step-by-step explanation:
Let's solve for x.
x+3y=−15
Step 1: Add -3y to both sides.
x+3y+−3y=−15+−3y
x=−3y−15
Answer:
x=−3y−15
Answer:
It's 21.
Step-by-step explanation:
The factors of 9 are 3 and 3. (You need to multiply 3x3 to get 9.) The factors of 10 are 5 and 2. But, if you multiply 3 by 5, which gives you 15, and multiply the other 3 by 2, which gives you 6, and then add 6 to 15, you get 21.
Answer:
L = 8
Step-by-step explanation:
The volume of a rectangular prism is found by V = L*h*w. Substitute V = 120, w = 5 and h =3 then solve for the length.
120 = L*3*5
120 = 15L
8 = L
