Mathematics
1 answer:
Dennis_Churaev [7]2 years ago
6 0

Answer:

Step-by-step explanation:

Rachel

d = 90 miles.

d = 90 * 1.6 km = 144 km

t = 1.25 hours.

Average speed = d/ time

Average speed = 144/ 1.25 = 115.2

Marc

d = 244 km

t = 2hr 30 minutes

30 minutes = 1/2 hour = 0.5 hours

Average speed = 244 km / 2.5 hours

Average speed = 97.6

Difference

Difference = Rachel - Marc

Difference = 115.2 - 97.6

Difference = 17.6

Two numbers multiply together to make 8, but add together to make - 6 What are the two numbers?​
Greeley [361]

Answer:

-4 and -2

Step-by-step explanation:

First find all the factors of 8, that would be 1 and 8, -1 and -8, 2 and 4, and -2 and -4.

Then, adding the groups of numbers you have should show you what would equal -6. So 1 + 8 = 9, -1 + (-8) = -9, same vice versa, 2 + 4 = 6, -2 + (-4) = -6. So -2 and -4 would be your two numbers.

The circumference of a circle is 36pi cm what is the radius
alexdok [17]

Answer:

The radius is 18 cm

Step-by-step explanation:

The formula for circumference with radius is

C = 2*pi*r

We know the circumference is 36 pi

36 pi = 2 * pi *r

Divide by pi

36 pi/pi = 2 * pi/pi *r

36 = 2r

Divide by 2

36/2 = 2r/2

18 = r
