Answer:

$9 or 9% less

Step-by-step explanation:

Original Price = OP

$75= OP

75 x .2 (20% discount) = 15

$15 discount

$75 - $15 = $60

$60 x .1 (service fee) = 6

$60 + $6= $66

Op ($75) - $66 = 9

$9 less than OP

How I check the percentage (probaly not how ur supposed to but ah well)

75 = 100%

75 + 25 = 100 but 25 more than 100%

66 + 25 = 91, also makes 75 100% again

100%-91%=9%

Jon hikes 12 mi at a constant rate of 3 mi/h.<br><br><br><br> How many hours does he hike?
Radda [10]

Because Jon is walking at a constant rate, the equation will be simple division. Because Jon walks 3 miles per hour, if you divide 12 miles by 3 miles per hour (12 mi / 3 mph), the miles in the equation cancel and you are left with 12 / 3 hours. 12 / 3 = 4, so Jon is hiking for 4 hours.

Which expression is equivalent to -32 to 3/5 power
levacccp [35]

<u>Answer:</u>

8

<u>Step-by-step explanation:</u>

We are given the following expression and we are to find the simplest form of this expression:

- 3 2 ^ { \frac { 3 } { 5 } }

First of all, we will factor the coefficient:

3 2 = 2 ^ 5

Rewriting it as:

- ( 2 ^ 5 ) ^ { \frac { 3 } { 5 } }

Applying the exponent rule (a^b)^c = a^{bc} to get:

-2^{5.\frac{3}{5}}=-2^3

-2^3=-8

James measured a piece of construction paper to be 6 3/4 inches wide and 9 2/3 inches long. What is the area of the piece of con
ivolga24 [154]

Answer:

The area of the piece of construction paper is \frac{261}{4} inches^2

Step-by-step explanation:

Length of construction paper =6 \frac{3}{4} inches

                                                 =\frac{27}{4} inches

Width of construction paper = 9 \frac{2}{3} inches

                                              = \frac{29}{3} inches

Area of construction paper =Length \times Width

Area of construction paper = \frac{27}{4}  \times \frac{29}{3}

                                             = \frac{261}{4} inches^2

Hence the area of the piece of construction paper is \frac{261}{4} inches^2
