Answer:
52 minutes
Step-by-step explanation:
it takes him 13 minutes to complete 5 so if he wants to do 20 problems do 20 divided by 5 (4) then do 13 times 4=52
Answer:
see explanation
Step-by-step explanation:
Using the tangent and sine ratios in the right triangle EFG
tan60° =
=
=
( multiply both sides by EG )
EG × tan60° = 28 ( divide both sides by tan60° )
EG =
≈ 16.2 in ( to the nearest tenth )
--------------------------------------------------------------
sin60° =
=
=
( multiply both sides by EF )
EF × sin60° = 28 ( divide both sides by sin60° )
EF =
≈ 32.3 in ( to the nearest tenth )
Hello from MrBillDoesMath!
Answer:
Choice B ( (x+6)/5) )
Discussion:
y = f(x) = 5x - 6
To solve for the inverse of f, replace "y" by "x" and "x" by "y" in the original equation. That is, solve for "y" in
x = 5y -6 => add 6 to both sides
x + 6 = 5y => divide both sides by 5
y = (x+6)/5
"y" above is the inverse, which is Choice B
Thank you,
