Answer: A
Step-by-step explanation:
Let the two numbers be x and y.
Let m = the fraction (or percentage) for increasing the numbers.
Increase x by 5, multiply (x+5) by (1+m), and set it qual to 36.
(x + 5)*(1 + m) = 36
Increase y by 5, multiply (y+5) by (1+m), and set it equal to 36.
(y+5)*(1+m) = 36
Therefore
(x+5)*(1+m) = (y+5)*(1+m)
x + 5 = y + 5
x = y
x - y = 0
Answer: 0.
The difference between the two numbers is zero.
Put the value of x = 6 to the eqpression 5x² + x - 7:
5(6)² + 6 - 7 = 5(36) + 6 - 7 = 180 + 6 - 7 = 179
<h3>Answer: 179</h3>
Answer:
28ft^2
Step-by-step explanation:
you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)
if we plug the numbers we are given into the formula we find
1/2(7x8)
1/2(56)
28
we find that the area of this triangle is 28ft^2
Answer:
Step-by-step explanation:
A)
<u>According to dimensions of the garage, the scale is:</u>
- 1 in : 20 ft, as the width of the garage is 20 ft and on paper is 1 in
B)
Living room
<u>Dimensions on paper: </u>
C)
<u>Actual dimensions: </u>
- 2*20 ft = 40 ft and
- 1 1/4 * 20 ft = 25 ft
D)
<u>The area of the living room:</u>
- A = lw = 25*40 = 1000 ft²
