Answer:

6 miles per hour

Step-by-step explanation:

Distance traveled, d = 2 1/2 miles = 5 / 2 miles

time taken, t = 5 / 12 hour

Speed is defined as the ratio of distance traveled to the time taken.

Speed = \frac{distance}{time}

Speed = \frac{\frac{5}{2}}{\frac{5}{12}}

speed = 6 miles per hhour

Thus, the unit rate of Chen is 6 miles per hour.

Answer: 6 miles per hour

Step-by-step explanation:

if you divide them both by 5, you would get 1/2 miles in 1/12 hour, so you multiply it by 12, 6 miles in 1 hour so his unit rate would be 6 mph

Anybody can help?????
Vikentia [17]

The formula of an area of a circle:

A=\pi r^2

r - a radius

We have r = 14m. Substitute:

A=\pi\cdot14^2=196\pi\ m^2

If you want an approximate area, you can accept \pi\approx3.14

Then:

A\approx196\cdot3.14=615.44\ m^2

Work out size of angle x
myrzilka [38]

Answer:

Step-by-step explanation:

Comment

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle

Equation

Cos(x) = a/c the way you have labeled it.

Givens

a = 9

c = 18

Solution

Cos(x) = a / c

Cos(x) = 9 / 18

cos(x) = 1/2

x = cos-1(1/2)

x = 60 degrees

Answer

x = 60
