Answer:
8.5
Step-by-step explanation:
1/9=0.1111111111111
0.1111111111111=0.1
83=80 or 85
0.1*85=8.5
Answer:
4.8 or about 5 miles
Step-by-step explanation:
In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in <em>one</em> mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.
I think it’s A not to sure and B
Area of a triangle = 1/2 x base x height
Area of original triangle = 1/2 x 7 x 10 = 35 square feet.
Add 1.5 feet to area to get 35 + 10.5 = 45.5 square feet.
Solve for the new height:
45.5 = 1/2 x 7 x H
Multiply both sides by 2:
91 = 7 x H
Divide both sides by 7:
H = 91/7
H = 13 feet
The new height needs to be 13 feet.
13 - 10 = 3 feet
The height has to increase by 3 feet.
