Answer:
y=5 when x=20
Step-by-step explanation:
Using the format for inverse proportions: y=k/x
To find k, substitute 25 in for y and 4 for x to find:
25=k/4 ⇒ k=100
Using this we can substitute k and x in for 100 and 20 to find:
y=100/20 ⇒ y=5
Answer:
3 decimal places
Step-by-step explanation:
square root of 11.737476 is 3.426
There are 4 lateral faces that are triangles. Each triangle is: A =

A =

= 176
There is one base that is a square. A = L x W
A = 16 x 16
= 256
Surface area = 256 + 4(176)
= 256 + 704
= 960
Answer: B
-4/3
Parallel lines have the same slope.
