Answer:

14mph

Step-by-step explanation:

First, lets find how many 16s can go into 60.

We can find this by doing 60 / 16 = 3.75

Then we need to find his average speed. We can find this by doing

18.4 * 3.75 = 69

To find how much he exceeded the speed limit, we will subtract 55 from 69

69 - 55 = 14

Therefore, Femi's average speed exceeded the speed limit by 14mph.

Erika worked 18 hours last week and 20 hours this week. If she earns $6 per hour, how much did she earn these two weeks?
Crank
Hi!

If she worked 18 hours last week and 20 hours this week, then she worked 38 hours in total, because 18 + 20 = 38.

If she earns $6 per hour, and she worked for 38 hours, then she got 38 sets of 6, which you can find the answer to by multiplying 38 and 6.

This is essentially 6 + 6 + 6 +...

38 * 6 = $228

So she earned $228 these two weeks.

Hope this helped!

Help me find the slope
shusha [124]

Answer:

-3/2

Step-by-step explanation:

Slope is defined as \frac{rise}{run},

So the line goes down 6 instead of rising, making the rise negative: -6

The line goes over 4, making the run: 4

So -6/4 or -3/2

What's the circumference of a circle that is 9cm? Please explain step by step of how you got the answer...
Sauron [17]

Formula for finding circumference of a circle is 2πr.

Step-by-step explanation:

  • The given question says what is the circumference of a circle that is 9cm.
  • As radius is required for finding circumference of a circle, the formula is 2πr.
  • Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
  • If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
  • So the circumference of the given circle would be 18π or 56.52 cms.
