of right angle triangle! .
<u>Step-by-step explanation:</u>
Here we have , A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 32 centimeters, and the length of the other leg is 25 centimeters. The student incorrectly says that the length of the hypotenuse is 7.5 centimeters. We need to find:
A)
We have , One length as 32 cm and other as 25 cm , as

By Pythagoras Theorem ,
⇒ 
⇒ 
⇒ 
⇒ 
So ,
of right angle triangle! .
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
Answer:
Number of monthly calls = 475
Step-by-step explanation:
Given:
Plan 1 = $30 per month unlimited calls
Plan 2 = $11 + $0.04(per call)
Find:
Number of monthly calls, plan 1 better than plan 2
Computation:
Plan 1 (Cost) < Plan 2 (Cost)
30 < 11 + 0.04(x)
19 < 0.04(x)
475 < (x)
Number of monthly calls = 475
Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
The correct answer is: 11
Here’s how you solve it!
You can remove the 0 since when you add or subtract 0 it stays the same.
Then you would want to look at the first set of parentheses (-20)
Since it is -(-20) this changes the sign to a positive +20
9-5+20+(-13)
Now since the + is in front of the (-13) it remains the same.
Now you are left with this:
9-5+20-13
9-5=4
4+20=24
24-13=11
Then you are left with your answer: 11
Hope this helps! :3
