alex41 [277]

Step-by-step explanation:

Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :

-320+15y

We need to find the depth of submarine after 15 ​minutes.

Put y = 15 in the above expression.

-320+15y = -320+15(15)

= -320 + 225

= -95

Hence, the submarine is below sea level at 95 feet.

I really need help on this question if anyone could help
miss Akunina [59]

Answer:

7986 square meter.

Step-by-step explanation:

Cut the composite shape into two shapes.

One rectangle and one triangle.

Rectangle area = 102×66 = 6732

A=lw

Triangle area = 66×(140-102)×1/2 = 1254

A=bh \times 1/2

Add the areas of the two shapes.

6732 + 1254 = 7986
