Answer:
Step-by-step explanation:
159.39(1-25/100)
159.39(100-25)/100
159.39(75)/100
159.39(0.75)
$119.54
4.99/17 = x/1
17x = 4.99
x=4.99/17
x =0.29
answer: unit rate is $0.29/lb
Answer:
y=90 when x=4
Step-by-step explanation:
We are given that

When x=8 and y=250
We have to find the value of y when x=4

Where k= Proportionality constant
Substitute the values




Now, substitute x=4 and k=5/2
Then, we get



Volume of sphere = 4/3πr³
r is radius.
Radius = diameter/2 = 16/2 = 8
Volume = 4/3(3.14)(8)³
Volume = 2143.57
Rounded to nearest tenth would be 2144.7 in³
The answer is D.
Hope this helps :)
