Answer:
Step-by-step explanation:
Given
Represent Fred with F; Norman with N and Dave with D.
Required
Determine the arithmetic mean of F and N
First, we have that:
Substitute 44 for D
Subtract 44 from both sides
Arithmetic mean of F and N is calculated as follows:
Answer: 9.5
Step-by-step explanation:
You need to do 115/12 and the answer is 9.5 so if that is not an answer it will be10 rounded up
Nearest 10 is according to the last digit.
if the digit is >5, it +1 to the tenth digit. If it's <5, it will be reduced to 0.
for your case, 392, 2 < 5, therefore rounded up to nearest tenth is 390.
Answer:
1) <
2) >
3) =
4) 138.75%
5) 4.4%
6) 87%
7) 166
8) 119%
9) 22.5%
10) I don't know, sorry!
11) I can't do the rest in my head I am sorry
Step-by-step explanation:
1) Because 25% is 1/4, not 1/5; 20% would be 1/5, for future reference
2) Move the decimal to the right twice, then put a percent sign!
3) I'm actually not 100% sure on this one, but I believe it's equal to, though. I am so sorry I couldn't get you a clear enough answer.
4) 75 ÷ 100 (may wanna use a calculator)
I am running outta time I am SO SORRY :( just remember on 4-7 to estimate, 8-10 round to the nearest tenTH, and 11-14 find each number to the nearest WHOLE number!!!
Answer:
its A and D
Step-by-step explanation:
i plugged them all in on my graphing calculator
4=49
-4=1
-7=16
