Answer:
We are given the expression:
Let us evaluate the expression step by step:
Step 1:
Power of a power: In this rule we multiply the powers 4 and (-5) in the numerator.
Step 2:
Quotient of power: Here we will subtract the power of denominator from numerator.
Step 3:
Negative exponent: Here we take reciprocal of what we got in step (2) , that will make the power positive.
Answer: We will use three rules as shown above .

Answer:
$4748.80
Step-by-step explanation:
First, find the cost with 20% off, by multiplying the price by 0.8
5600(0.8)
= 4480
Find the cost with tax, by multiplying this by 1.06
4480(1.06)
= 4748.8
So, the sale price, including tax, is $4748.80
9514 1404 393
Answer:
14.4 or 15 bags
Step-by-step explanation:
The number of yards covered by x bags is ...
(3 1/2)x = 50 1/4
x = (50 1/4)/(3 1/2) = 50.25/3.5 ≈ 14.4*
We assume that bags of chips are available only in integer quantities.
The PTA will need 15 bags of wood chips to cover the wet section.
_____
* The exact answer is 14 5/14. We hope that an integer number is the desired solution, as anything more precise than that seems inappropriate in this context.
Answer:
12 beats per minute after 30minutes
Step-by-step explanation:
Since we are told by how much his heartrate increased in 20 minutes, we can simply calculate how much it increased in 10 minutes and add that amount to the current heart rate to know how much his heartrate increased after 30 minutes of working out. Since 10minutes would be half of the 20minutes we simply divide the beats per minute by 2.
8 / 2 = 4 beats per minute after 10 minutes
Now we simply add this to the beats per minute at the 20minute mark to calculate the beats per minute at 30minutes
8 + 4 = 12 beats per minute after 30minutes
