Answer:
1.25 miles
Step-by-step explanation:
Lisa takes a night walk after dinner every night.
She walks 1/4 mile in 2 minutes.
Distance = 1/4 mile
Time, t = 2 minutes
For covering 1 mile,
1/4 mile = 2 minutes
In 1 minute she will cover
For 10 minutes, she will cover
So, she will cover 1.25 miles.
The formula for the circumference of a circle of radius r is C = 2pi*r.
Here we know that the circumference is 42 inches, and we need to find the radius, r. Solving this equation for r, we get:
42 inches
r = ------------------ = 6.68 inches, to the nearest hundredth.
2(3.14)
Answer:
1) = 9³
2) = 4*4*4*4*4
= 4 to the fifth power
Step-by-step explanation:
F(x)=9x
f(X)=9(-2)
f(x)= -18
Answer:
x² - 16
Step-by-step explanation:
Given
(x - 4)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 4) - 4(x + 4) ← distribute both parenthesis
= x² + 4x - 4x - 16 ← collect like terms
= x² - 16
