Answer:
P = 321.3m
Step-by-step explanation:
To help simplify the process of solving this problem, first break it up into different shapes. Here, you have two shapes: a rectangle and a circle (1 semi-circle + 1 semi-circle = 1 circle).
Next, use the equation for circumference of a circle to find the first part of the perimeter (C = πd). In this case, the diameter would be 45m.
- C = πd
- C = 3.14 × 45
- C = 141.3 m
This is the first part of the circumference. Now, you must consider the rectangle. (Because the two shorter sides of the rectangle are not part of the perimeter, do not include these in your final answer.) The length of the rectangle is 90 meters, and since both sides that measure to 90m are part of what makes up the perimeter, lastly add these to the circumference you calculated earlier.
- (90 + 90) or (90 × 2) = 180
- P = 141.3 + 180
- P = 321.3m
Hope this helps! : )
Number of questions worth 5 points = 10
Number of questions worth 2 points = 25
Further explanation:
The given system is a system of linear equations in two variables.
We will use the subsitution method to solve the system
Given equations are:
From equation no 1:
Putting x=35-y in second equation
Hence,
Number of questions worth 5 points = 10
Number of questions worth 2 points = 25

The interest paid for the loan will be:
I=(PRT)/100
P=$749.25
R=12%
T=120 days=120/30=4 months=1/3 years
Hence:
I=(749.25×1/3×12)/100
I=$29.97
The proceeds will be:
Net proceeds=(gross proceeds)-(expenses)
=749.25-29.97
=$719.28
I’d need to know the question to answer this.
Answer:
<u><em>Measure of angle A is 27 7/9 degrees.</em></u>
Step-by-step explanation:
Lets call measure of angle A is <em><u>X-10</u></em>
Lets call measure of angle B is X
Lets call measure of angle D is 2.5X+20
We know that the sum of triangles add up to 180 degrees
X+X-10+2.5X+20=180
X=37 7/9
So measure of angle A is 27 7/9 degrees.
I hope this is right. :)
