An excavation has a volume of 203 cubic feet. the material weighs 1,200 pounds per cubic yard. what is the weight of the exca- vation? a. 2,700 pounds b. 9,000 pounds c. 81,120 pounds d. 243,600 pounds

Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Volume of an excavation = 203 cubic feet

Weight of the material = 1200 pounds per cubic yard

So, the weight of the excavation would be

Volume of an excavation × Weight of the material

Hence, the weight of the excavation is 243,600 pounds.

Therefore, Option 'd' is correct.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: i think it's a
