This is just the perimeter so add all of the numbers up. 4.2 + 9.4 + 4.6 + 5.6 = 23.8.

Multiply 23.8 by 7.4 to convert it to meters. 23.8 X 7.4 =171.36

Answer: 15 feet

Step-by-step explanation:

From the question, we are informed that a diving board is 10 feet above a pool. Since the ladder is 5 feet away from the base of the diving board, to calculate how tall is the ladder is, we subtract -5 from 10. This will be:

= 10 - (-5)

= 10 + 5

= 15 feet

The answer is option C.

Thisssss oneeeeee :)?????

Answer:

y = 3x - 5

Step-by-step explanation:

I used my calculator so that it would be faster.

But if you want work you have to find the slope then plug in.

To find the slope use points (1, -2) and (2, 1) use this formula $\frac{y2 - y1}{x2 - x1}$

Plug the points in $\frac{1 - -2}{2-1} =\frac{3}{1} = 3$

So your slope is 3

NOw Plug In (1, -2)

-2 = 3(1) + b (b represents the y- intercept)

-2 = 3 + b (subtract 3 on both sides)

-5 = b

The final equation is y = 3x - 5

Hope this helps ya!!
