Say the percentage increase is 25%. If you have the whole number of 30 then you would multiply 30 by .25. You should therefore get 7.5 once both are multiplied. That means you should add 7.5 to 30, and your final answer will be 37.5.
See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
-4.7
-8.1 - -3.4= -4.7
-4.7+-3.4=-8.1
Answer:
Step-by-step explanation:
1) Convert to Standard Form:
9.29 * 10^7 = 92900000
4.8388 * 10^8= 483880000
2) Subtract 483880000 from 92900000.
3) Convert the difference into scientific notation.

<em>C would be your best choice.</em>
Answer:
50
Step-by-step explanation:
it is given that there is one variable with 1000 records
we have to find the records which is expected would be removed
it is given that one variable is missing with 5% that 0.05
we can find missing records by multiplying total number of records and the missing value with one variable
so the expected record removed will be =0.05×1000=50
