Answer:

Step-by-step explanation:

1.

hours      1/2      1         1.5       2        2.5         3          3.5        4

charges  3.25    6.50   9.75   13.0    16.25    19.50   22.75   26.00  

2. The garage rate of parking is ;

$3.25 = 0.5 hr

?=1----------------------twice the charge for half an hour

=2*3.25=$6.50

$6.50 per hour

3.

$6.50=1 hour

$42.25=?------------------cross multiply

$(42.25*1)÷$ 6.50 = 6 hrs 30 min

Answer:

The required table is shown below:

Hours         1/2          1         1.5        2        2.5          3          3.5        4

Charges   $3.25  $6.50  $9.75  $13.0  $16.25  $19.5  $22.75   $26

Garage's unit rate for parking $6.50.

She park her car at the garage for 6\frac{1}{2} hours.

Step-by-step explanation:

Consider the provided table.

Part (A)

The owner charges $3.25 for 1/2 hour.

This can be written as:

1/2 hours = $3.25

Multiply both the sides by 2.

1 hour = $6.50

For 1\frac{1}{2} he will charge: $6.50 + $3.25 = $9.75

Similarly, you can solve for other values.

The required table is shown below

Hours         1/2          1         1.5        2        2.5          3          3.5        4

Charges   $3.25  $6.50  $9.75  $13.0  $16.25  $19.5  $22.75   $26

Part (B)

Now we need to find the garage's unit rate.

Unit rate is how much of something per 1 unit of something else.

From the table we can say that garage's unit rate for parking $6.50.

Part (C)

Kristin was charged $42.25 for parking.

The charges for per hour is $6.50. Let Kristin park her car for x hours.

Thus, the charge for x hours will be x times 6.50. This can be written as.

6.50x=42.25\\x=\frac{42.25}{6.50} \\x=6.50

It is required the answer should be in mixed fraction.

Thus, she park her car at the garage for 6\frac{1}{2} hours.

soldier1979 [14.2K]
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170

And that is the answer.
