Answer:

75 feet per hour is the rate of change in altitude.

Step-by-step explanation:

A climber is on a hike. After 2 hours he is at an altitude of 400 feet.

After 6 hours, he is at an altitude of 400 feet.

We have to determine the average rate of change in altitude.

We know rate of change in altitude = \frac{\text{(Change in altitude)}}{\text{Change in time}}

= \frac{700-400}{6-2}

= \frac{300}{4}

= 75 feet per hour

Therefore, 75 feet per hour is the rate of change in altitude.

Average rate of change =
(change in height during some time) / (length of time for the change).

Change in height = (700 feet - 400 feet) = 300 feet

Time for the change = (6 hours - 2 hours) = 4 hours

Average rate of change = (300 feet) / (4 hours) = <u>75 feet per hour</u>

Find the value of x.
ruslelena [56]

Answer:

4

Step-by-step explanation:

(10 - x ) / x = 3/2                Cross Multiply

2*(10 - x) = 3x                    Remove the brackets

20 - 2x = 3x                       Add 2x to both sides

20 = 3x + 2x

5x = 20                              Divide both sides by 5

x = 20/5

x = 4

Ashely is making $500 a week at her job. She receives a 20% pay raise. A year later she takes a 5% pay cut. How much money does
zheka24 [161]

Answer:

<em>$570 a week</em>

Step-by-step explanation:

<u>Percentage Calculations </u>

One tricky fact about percentages is that they are usually performed over the last computed quantity. It makes them non-additive. For example, a raise of 10% followed by a 10% some time later, is NOT a 20% of total raise

The question states Ashely is making $500 a week at her job and that she receives a 20% pay raise. After that raise she will make

\$500*(1+20/100)=\$500(1.2)=\$600 \text{ a week}

A year later she takes a 5% pay cut. We must be careful to take that percentage from the last earnings. She now makes

\$600(1-5/100)=\$600(0.95)=\$570\ a\ week
