Answer:
The first piece is 15 in and the second piece is 21 in
Step-by-step explanation:
5 + 7 = 12
3 ft = 3 x 12 in = 36 in
36 ÷ 12 = 3
5 x 3 = 15 7 x 3 = 21
The first piece is 15 in and the second piece is 21 in
15% of 15% of 15% of 500 is 1.6875. 45% of 500 is 225. The difference between both numbers is that 225 is much larger than 1.6875. In fact 225, is 133 1/3 times larger than 1.6875. The more you repeated 15% of a number, the smaller it got, compared to 45% of the number, where it was larger than that number you kept reducing by percentages.
X= -2 or X= 3 either one works.
By using what we know about polynomials, we will see that the missing side measures 8x - 1
<h3 /><h3>How to get the perimeter of a triangle?</h3>
The perimeter of a triangle is just the sum of its 3 sides, in the image the two known sides are: 3x - 5 and x + 2, and the missing side measures p(x).
Then we will have that the perimeter is the sum of these 3 lengths:
13x - 4 = 3x - 5 + 2x + 2 + p(x)
13x - 4 = 5x - 3 + p(x)
Now we can assume that p(x) is also a linear polynomial, so:
p(x) = a*x + b
Then we have:
13x - 4 = 5x - 3 + a*x + b
This means that:
5 + a = 13
-3 + b = -4
Solving these we get:
a = 13 - 5 = 8
b = -4 + 3 = -1
This means that the missing length is:
p(x) = 8x - 1

We are asked to determine the number that is between 0.5 and 5/8. In this case, 0.5 is equal 1/2. To find the number in between, we find the average of the two numbers. The LCD of 2 and 8 is is 8 so 1/2 is equal to 4/8. 4/8 + 5/ 8 is equal to 9/8. 1/2 of 9/8 is equal to 9/16.
