Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps
Answer:
y= 1/4x + 1
Step-by-step explanation:
Hey You!
This question is asking us, "75 is 75% of what number?"
75 × 100 / 75 = 100
The original cost was $100.
To cube something means to take it by 3, when used in the sentance, 3 cubed it refers to 3^3 power which means 3*3*3 which equals 21. In this context I'm guessing that they mean 50^3 which would be $125,000.
Hope this helps!=)
