X = 25 dollar items and y = 15 dollar items
x + y = 72....x = 72 - y
25x + 15y = 1380
25(72 - y) + 15y = 1380
1800 - 25y + 15y = 1380
-25y + 15y = 1380 - 1800
-10y = - 420
y = -420/-10
y = 42
x + y = 72
x + 42 = 72
x = 72 - 42
x = 30
so they sold 30 twenty five dollar items (x) and 42 fifteen dollar items (y)
Hi,
First we should calculate within the parentheses to get 343^3
then we calculate the exponent to get 40,353,607.
But the simplified version is 343^3
Have a great day!
Answer:
250/3π cubic inches
Step-by-step explanation:
we know that
The volume of the space between the cylinder and the sphere is equal to the volume of the cylinder minus the volume of the sphere
step 1
Find the volume of the cylinder
The volume of the cylinder is equal to
we have
substitute
step 2
Find the volume of the sphere
The volume of the sphere is equal to
we have
substitute
step 3
Find the difference
![250\pi\ in^{3}-(500/3)\pi\ in^{3}=(250/3)\pi\ in^{3}](https://tex.z-dn.net/?f=250%5Cpi%5C%20in%5E%7B3%7D-%28500%2F3%29%5Cpi%5C%20in%5E%7B3%7D%3D%28250%2F3%29%5Cpi%5C%20in%5E%7B3%7D)
Answer:
$50
Step-by-step explanation:
When finding sales price you multiply. But here we are finding the original price. So now you do the opposite, divison.
20/.4 = 50
