We can create two points.

30 feet below the surface of the water 10 seconds after he entered the water
100 feet below the surface after 40 seconds

So we have (10, 30) and (40, 100)

Plug this values into the slope formula:

m = y2-y1/x2-x1

m = (100 - 30)/(40 - 10)

m = 70/30

m = 2 1/3

8/2(2+2)=<br><br> A. 16<br> B. 1<br> C. 0<br> D. 10
s2008m [1.1K]

The answer to this problem is 16.

To solve we must follow the order of operations.

8/2 is 4.

2+2 is 4.

So, now we multiply 4(4) and will get 16 as the answer

So, 16 is the answer.

There are 12 pizzas on a table for a birthday party.
Rom4ik [11]

Answer:

120 slices

Step-by-step explanation:

We are given that each slice is 1 over 10 of a pizza, so there are 10 slices per pizza (because the denominator represents the total amount of pieces). Since there are 12 pizzas, 12 x 10 = a total of 120 slices.
