Answer:
20
Step-by-step explanation:
We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
Step 1 ---> 3.4 = 17% × Y
Step 2 ---> 3.4 = 17/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:
Step 3 ---> Y = 3.4 × 100/17
Step 4 ---> Y = 3.4 × 100 ÷ 17
Step 5 ---> Y = 20
Finally, we have found the value of Y which is 20 and that is our answer.
<h3><u>
*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</u></h3>
No because a perfect square would be 1 whole number times itself. and no number times itself equals 27
Answer:
it will still be zero
Step-by-step explanation:
12-12 = 0
Answer:
(a/b)^k=a^k/b^k
Step-by-step explanation:
Using the laws of exponents, we know that (a/b)^k=a^k/b^k.
I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.
Answer:
D
Step-by-step explanation:
Without doing any math, you can deduce that in a data set with the values 20, 30, and 50, the only possible number you could add that could bring the mean (average) to 50 would be D or 100. But this method will not always work so instead I'll show how to do it mathematically:
(20 + 30 + 50 + x)/4 = 50
20 + 30 + 50 + x = 200
100 + x = 200
x = 100
