You have constructed wooden forms for pilings. the pilings are in the shape of rectangular solids, each measuring 10 ft. high and 3 ft. square. you are now going to pour cement into 10 of these forms. how much cement will you pour? volume of cement (to the nearest cubic foot) = cubic feet.

300 cubic feet cement

Step-by-step explanation:

Given: The pilings are in the shape of rectangular solids,the height of the piling = 10ft.

The length of the piling = 3 ft. square

Now, since we are going to pour cement into 10 of these forms.

Thus, the amount of the cement we will pour is given by ;-

Hence, we will pour 300 cubic feet cement.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
