For this case what you must do is to determine the value of r of the given equation:
A = pi * r ^ 2.
Clearing the value of r we have:
r = root (A / pi)
Note that r has two roots:
r1: = + root (A / pi)
r2: = - root (A / pi)
In this case we must ignore the negative root.
Answer:
The formula to find r is
r = root (A / pi)
For this item, we represent the very original value or price of the given item by x such that increasing the retail price by 40 percent will give us 1.4x. Also, when the retail price of the item is reduced by 25 percent, we have.
new retail price = 1.4x (1 - 0.25) = 1.05x.
This means that the new retail price is only 5% over the manufacturer price.
10 out of 200 because there is 10 marbles and 200 times you reach and grab one it would be a 10 out of 200 chance
It is already given in the question that there are 8 pencils in 1 packet. Based on this information the answer to the question can be easily found out.
Then
Number of pencils in 7 packets = 8 * 7
= 56
So there are 56 pencils in 7 packets. I hope you have got the answer you were looking for. This method would allow you to answer any question of this type.
Answer:
1
Step-by-step explanation:
Yes the answer is just 1
Since the power of 2 in the inside will be multiplied by the power of the 4 in the outside will be 8 (The number 11 doesn't change)
A power divided by a power that is equivalent to it is 1
