If you would like to know the change in Debra's hours, you can calculate this using the following steps:
x% of 16 hours is 22 hours
x% * 16 = 22
x/100 * 16 = 22
x = 22 * 100 / 16
x = 137.5%
137.5% - 100% = 37.5%
22 hours - 16 hours = 6 hours
The correct result would be: an increase of 6 hours, and an increase of 37.5%.
In the given question there is an equation that has to be solved and the value of the unknown variable "M" has to be determined. It is absolutely possible to find the exact value of the variable "M" as there is 1 equation and 1 variable.
302 + 12 M = 278
12 M = 278 - 302
12 M = - 24
M = - (24/12)
= - 2
So the value of the unknown variable "M" comes out to be -2. I hope the procedure is clear enough for you to understand and also this is the answer you were looking forward to.
Given:
Larger Triangle : base = 58 m ; height = x
Smaller Triangle: base = 26 m; height = 21.3 m
x:58 = 21.3:26
26x = 58*21.3
26x = 1,235.4
x = 1,235.4 / 26
x = 47.515

Answer:
the length of the shortest ladder is 11.41 feet
Step-by-step explanation:
The computation of the length of the shortest ladder is shown below:
AB^2 = AC^2 + BC^2
AB^2= (10)^2 + (5.5)^2
AB^2= 100 + 30.25
AB^2 = 130.25
AB = 11.41 feet
hence, the length of the shortest ladder is 11.41 feet
The answer is A.
I only know how to explain by using the rule for reflection over x axis sorry.
The rule is (x,-y) x coordinate stays the same but you do the opposite for the y coordinate so -7.05 would be 7.05
