$400 - $20 = $380 ( The original charge subtract the amount he paid. )
$380 + $18 = $398 (The amount unpaid plus another charge equal total amount unpaid.)
$398 x 0.02 = $7.96 (The amount unpaid multiply the percentage of interest = amount of interest.)
Phillip charged $7.96 interest on his second bill.
Answer:
44
Step-by-step explanation:
the answer is 44 because 44 is the average and your wondering how i got 44 you add all the numbers up which will be 54 and divide by all the total numbers you have so in that case you hvae 6 numbers so 54 divide by 6 is 44
2304 cubic inches. You multiply the length, width, and base
Answer:
x=3 meters
Step-by-step explanation:
step 1
Find the area of the rectangular pool

we have

substitute

step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have

substitute

step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so

step 4
Find the value of x if the area of the walkway equal the area of the pool
so

Solve for x

Solve the quadratic equation by graphing
The solution is x=3 meters
see the attached figure
Answer:
9/pi or 2.865
2.25/pi or 0.716
9/25pi or 0.115
36/pi or 11.459
Step-by-step explanation:
The formula for the volume of a cone
V= 1/3pir^2h
V= volume
pi= 3.141592...
r= radius
h= height
1) 3= 1/3pi (1)^2h
9=pi(h)
h= 9/pi or 2.865
2) 3= 1/3pi (2)^2h
9=4pih
h= 9/4pi or 0.716
3) 3= 1/3pi (5)^2h
9= 25pih
h= 9/25pi or 0.115
4) 3=1/3pi (1/2)^2h
9= 1/4pih
h= 36/pi or 11/459
