You would need to find out how much feet he dropped in the space of 3 mins by subtracting 2,100 and 150 that will give you 1950 then you divide that by 3 which count as your minutes and you get 650 feet per minute
Answer:
21m+5
Step-by-step explanation:
13m-(-8m-5)
13m+8m+5
21m+5
You are adding 2 each time.
4 terms are given to you, with 5th term being 2
20 - 5 = 15
Multiply 15 with 2
15 x 2 = 30
Add the number gotten with the last number given
30 + 2 = 32
32, or (A) is your answer
hope this helps
The answer is the first and the third figure,attached
Find the are of the pool by dividing the volume by the depth:
1960 / 4 = 490
The pool is 490 square feet.
Area is found by multiplying the length by the width.
Let the width = X
We are told the length is 2.5X ( 2.5 times longer)
So we now have 2.5x * x = 490
2.5x * x = 2.5x^2
Now we have 2.5x^2 = 490
Divide both sides by 2.5:
x^2 = 490/2.5
x^2 = 196
find X by taking the square root of 196:
x = √196
x = 14
The width is 14 feet
The length is 2.5 * 14 = 35 feet
