-- Look at the two numbers.
-- Say to yourself: "Self ! 3.9 is close to 4, and 5.3 is close to 5.
So the product is going to be close to (4 x 5) = 20."
-- Then do the real multiplication.
-- On your paper or your calculator, you see the digits 2 0 6 7 .
-- From your estimate (20), you know that it can't possibly be
2.067 or 206.7 or 2,067. It must be 20.67 .
Answer:
The unit rate for 0.75 is Answer: 75%
Step-by-step explanation:
Because it is actually converting decimals to percentage.
Tan 40 = h / 20 where h = height of the pole.
h = 20 tan 40 = 16.78 feet
Answer:
Divide both sides by 4 to get c - 3 = 2 ( second to last choice)
Use the distributive property to get 4c - 12 = 8 (last choice)
Step-by-step explanation:
1. Use distributive property
4 times c = 4c
4 times 3 = 12
2. Since we are multiplying by 4, we can divide by 4 on both sides.
4(c - 3) divided by 4 = c - 3
8 divided by 4 = 2
