Answer:
Step-by-step explanation:
the expression is equivalent to (cd)5 : c^5×d^5
The main thing you need to know for this question is this conversion:
1 L = 1000 mL , or 1 liter is equal to 1000 milliliters.
So, let's make the entire problem into milliliters:
The carton of milk has 2,500 mL, and Zoe drinks 500 mL a day (250 twice a day).
To find the number of days the bottle will last, you divide the total amount of milk by the amount she drinks per day:
2,500 / 500 = 5 days
Answer:
39
Step-by-step explanation:
284-5(7)²
284-(5×49)
284-245
39
Answer:
D. 64
Step-by-step explanation:
Setup an equation to solve for the missing test, x. Since you are doing average and there are three tests, divide the left side of the equation by 3. Set the equation equal to 60 since that is what we want the average to be.
Multiply both sides by 3 to remove it from the denominator.
Simplify and solve for x.
Answer:
8.84 x 10^3
Step-by-step explanation:
first, you need to turn the digits in 8840 so it is lower than 10 and at least 1
so 8840 ÷ 1000 gives us 8.840, or 8.84
Then, we need to add the multiplication that makes the original number
8.84 x 1000 = 8840
We simplify this by counting the factors zeros
1 0 0 0 = 3 zeros
Finally, but the amount of zeros in the exponent
8.84 x 10^3
