Answer:
The answer is 130 feet
Step-by-step explanation:
Using Pythagoras' Theorem:
120² + 50² = diagonal²
diagonal² = 16900ft
diagonal = √16900
= 130ft
(Correct me if i am wrong)
Look at the problem and work shown. In which line was an error made and what should have been done differently?

Hey there :)
Let us first translate the sentence into mathematics!
Seven less than 5 times a number is 62
Less than means minus
seven less than is 'something - 7'
"Is" is where = sign comes
Let n represent a number
5n - 7 = 62
Take 7 to the other side [ Add when you see minus sign ]
5n - 7 ( + 7 ) = 62 + 7
5n = 69
Take 5 to the other side in order to isolate n [ Divide when you see multiplication sign ]
5n ÷ 5 = 69 ÷ 5
n = 13.8
Therefore, we can notice that the error has occurred in the first line

Given:
a. 35% of 150 g
b. 113% of $55
To find:
The correct values for the given blanks.
Solution:
a. 35% of 150 g
Here, the percent part is 35% and percent whole is 100%.
35% of 150 g is:
So, the number part is 52.5 g and the whole number is 150 g.
Therefore, the percent part is 35%, number part is 52.5 g and the whole number is 150 g.
b. 113% of $55 g
Here, the percent part is 113% and percent whole is 100%.
113% of $55 is:
So, the number part is $62.15 and the whole number is $55.
Therefore, the percent part is 113%, number part is $62.15 and the whole number is $55.
