A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 100 feet below the surface aft
den301095 [7]

Answer:

2.3 feet/ second

Step-by-step explanation:

To find the rate of change, we will have to find the difference in his distance travelled and divide it by the time taken to move that distance.

This is given by rate of change = (change in position)/ change in time

From the question, his position changed from 30 ft to 100 ft thus the distance he travelled is = 100ft - 30 ft = 70 ft.

Time taken to travel this distance = 40 seconds - 10 seconds = 30 seconds

Diver's rate of travel = 70 ft / 30 seconds = 2.33333ft/second.

Rounding off the answer to the nearest tenth, we have 2.3 ft/second

The length of a rectangle is five more than the width. The perimeter is 130cm. What is the area?
Evgen [1.6K]
<h2>Greetings!</h2>

Answer:

≅ 586.8

Step-by-step explanation:

Take x to be the width, if the length is 5x bigger than the width, then this can be shown by 5x.

The total perimeter is:

(2 * x) + (2 * 5x) because each side has another parallel one.

This means that 2x + 10x = 130

12x = 130

Divide both sides by 12:

\frac{12x}{12} = \frac{130}{12}

x = \frac{65}{6}

So the area = length * width

x * 5x = area

Substitute the values in:

\frac{65}{6} * (5*\frac{65}{6}) = 586.8055... ≅ 586.8

So the approximate area is 586.8
