Answer:

The average speed is:

\var{v}=75\: miles/h

Step-by-step explanation:

The average speed equation is given by:

\var{v}=\frac{\Delta x}{\Delta t}

Were:

  • Δx is the displacement (225 miles)
  • Δt is the change in time (3 hours)

Then we have:

\var{v}=\frac{225}{3}

\var{v}=75\: miles/h

I hope it helps you!

3 Shamaya went shopping for school supplies. She bought 2 packages of
allsm [11]

Answer:

a.  $17.83

b.  $82.17

Step-by-step explanation:

a.

We need to find total cost of all the items.

2 package of pencil for 1.98 each: Total = 1.98 * 2 = 3.96

1 binder for 7.69:  Total = 7.69

1 divider for 2.69:  Total = 2.69

1 pencil box for 3.49:  Total = 3.49

We sum all of these to get:

3.96 + 7.69 + 2.69 + 3.49 = $17.83

b.

She only spent 17.83 and she had 100 dollars. So we subtract amount spent (17.83) from total (100) to get remaining balance.

100 - 17.83 = $82.17

If the perimeter of a rectangular picture frame must be less than 180 in, and the width is 26 in, what must the height h of the
valentinak56 [21]
You would form this inequality:

52 + 2x < (or equal to) 180

Then, solve as you would in an ordinary equation.

Subtract 52 from both sides of the sign. 180 - 52 = 128.

So, 2x is less than or equal to 128.
Divide 128 into two to get 64.

The height of the frame must be 64 inches.
