V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
Answer:
3) C) $792.50
4) D) $707.50
Step-by-step explanation:
3) Home price = $ 253,600
Mortgage rate = 3.75% APR
Therefore, monthly rate = 3.75% divide by 12
= 0.0375/12
= 0.003125
1st month interest = principle * 0.003125
= 253600*0.003125
=$792.50
3) Answer: $792.50
4) You paid $1500
The first monthly interest = $792.50
Principal paid in the first month = 1500 - 792.50
= $707.50
Answer: D) $707.50
Thank you.
Answer:
8 inches
Step-by-step explanation:
4/5 * 10/1 = 40/5 = 8inches
The perimeter of an object is found by adding all of the sides. The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet. Adding these together we get a total length of 7 feet. However, he may want to use a slightly longer board to account for any errors!
