Answer:
the answer is 217.
Step-by-step explanation:
First, we subtract the two numbers.
72 - 42 = 30
Now we divide this to the original number.
30 / 42 = <span>0.71428571428
Multiply by 100:
</span><span>71.428571428
</span>
So the percent increase is approximately 71.43%
answer is D
graduent should be m¹×m²=-1
and should be the inverse of the other
Answer:
16.65
Step-by-step explanation:
15 percent of 111 is the same as 15 per hundred of 111. We can therefore make the following equation:
15/100 = X/111
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 111, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
15/100 = X/111
X/111 = 15/100
X*111/111 = 15*111/100
X = 1665/100
X = 16.65
or
The work above shows the long way to explain how to calculate 15 percent of 111 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 15 percent of 111?", Y is 111 and P is 15:
(111 * 15)/100 = 16.65
And once again you see that the answer is 16.65.
Answer: 10 cm
Step-by-step explanation:
The circumference of the CD = 22\pi
We know that the formula of the circumference is:
Circumference = 2\pi r
We will substitute the value of circumference to find the radius:
22 pi = 2 x pi x r
r = 11
Therefore its radius will be 22 / 2 = 11 cm
Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:
11 - 1 = 10 cm
