Formula
d = r*t

Sub and Solve
d =30 miles
t = 2 hours
r = ?

30 = r * 2 Divide by 2
30/2 = r
r = 15
The units are in miles per hour.

r = 15 miles per hour.

You work as a cashier for a bookstore and earn $4 per hour. You also babysit and earn $8

Anna71 [15]

Answer:

The correct option is C

Step-by-step explanation:

Lets find the linear equations:

For Hours

Let

Number of hours in bookstore per week = x

Number of hours for babysitting per week = y

Total number of hours ≤ 16

So the first equation us:

x + y ≤ 16

y ≤ 16 - x

For Money

Let

Amount earned per hour from bookstore = $4

Total Amount earned from bookstore = 4x

Amount earned per hour from babysitting = $8

Total Amount earned from babysitting = 8y

Total Amount earned ≥ $56

So the second equation is:

4x + 8y ≥ 56

8y ≥ -4x + 56

y ≥ -(1/2)x + 7

Answer for brainlest and 25 points

nordsb [41]

Answer:

Order from greatest to least: 10.5, $3\pi +1$ , $\sqrt{105}$

Step-by-step explanation:

step 1 simplify each number

3π + 1 = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

$\sqrt{105} =10.2469507$

*round to the nearest tenth*

$\sqrt{105} =10.2$

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = $\sqrt{105}$

Your answer is

10.5 , 3 $\pi$ + 1, $\sqrt{105}$
