Answer:
C) 16, 6
Step-by-step explanation:
- Set AB and DC equal to eachother. 4x = x + 12.
- Subtract x from both sides. 3x = 12
- Divide by 3 to get x alone. x = 4
- Plug this x value in the equation for AB. 4•(4) = 16
- We know the AD equals 6, so that will be one of the values and we now know that AB equals 16.
Answer: You can simply use a calculator.
Step-by-step explanation:
Answer: 21
Step-by-step explanation: In these types of problems, you use inverse operations. The inverse operation for multiplying is dividing. 42 divided by 2 is 21.
Round 358 to the nearest 5 or 10, which would be 360. 360/3=120 so the compatible number would be 120.
(1/2)×(3/4)×(2/5)=5/40=1/8
as a decimal, this is .125
for scientific notation, you must move the decimal one place to the right, so the answer is
1.25×10^-1 ft^3
