20
Step-by-step explanation:
the inverse of
y=1/2x + 10
is
x=1/2y+10
from here you just solve for y
x-10 = 1/2y
2(x-10) = y
2x-20 = y

Step-by-step explanation:
Call w the unknwon price of the walnuts, then:
total cost of walnuts = 1oz * w
Total cost of peanuts = 4 oz * $4/oz = $16
Total cost of nuts = 5oz * $5 /oz = $25
=> 1oz*w + $16 = $25 => w = ($25 - $16) /1oz = $9/oz
Verfify:
1oz * $9/oz + 4oz * $4/oz = $9 + $16 = $25, which is equal to 5oz * $5/oz.
Answer: $9 per oz.
The lateral surface area of a cylinder is:
a=2πrh, we are told that r=1.8ft and h=4ft so
a=2π(1.8*4)
a=2π(7.2)
a=14.4π ft^2
a≈45.24 ft^2 (to nearest hundredth of a square foot)
