72 Kilometers = 72000 meters
1 hour = 3600 seconds
So if 72000m = 3600 secs
To find 1 sec, divide through by 3600
20m = 1 sec
To find the distance travelled in 15 secs we multiply by 15
300m = 20 secs
Answer:
She applied the exponent -2 to 4(-2) instead of applying the exponent to just -2
Step-by-step explanation:
we have the expression

Simplify

Substitute the values of m and n in the expression
For

She applied the exponent -2 to 4(-2) instead of applying the exponent to just -2
The answer is C 15
150 x 0.10 = 15

The measure of the smallest side of the triangle is 10 inches
<h3>Perimeter of a triangle</h3>
A triangle is a shape that has 3 sides and angles. The perimeter of a shape is defined as the sum of the sides of the figure.
Let the length of the smallest side be x
If one side is 5 inches longer than the smallest side, then;
L1 = x + 5
If another side is 1 inch less than twice the smallest side, then;
L2 = 2x - 1
Take the sum to have:
x+x+5+2x-1 = 44
4x+4= 44
Subtract 4 from both sides
4x =44 - 4
4x = 40
Divide both sides by 4
x = 40/4
x = 10
Hence the measure of the smallest side of the triangle is 10 inches
