Answer: No
Step-by-step explanation: If you mean 3^-2 it would be 0.111111111 repeating. 3^2 is 9 not -2
Answer:
True
Step-by-step explanation:
Correct.
For example.
Suppose the actual yield is of 80 and the theoretical yield is of 100. We want to, for example, know the percentage of the yield. First we divide 80 by 100, which is 0.8, a decimal value. To write as a percentage, we multiply it by 100.
So the correct answer is:
True
Answer:
Okay, but doesn't this bring any trouble reading?
Answer:
126
Step-by-step explanation:
2=1³+1
9=2³+1
28=3³+1
65=4³+1
=>5³+1=126
The rule is: n³+1
Three times (3 times something) the difference of x and 2 (2-x) is greater than (>) -21 (-21)
3 times (2-x)>-21
3(2-x)>-21
distrobite using distributiver poerpoty
a(b+c)=ab+ac
3(2-x)=6+(-3x)=6-3x
6-3x>-21
add 3x to both sides
6>-21+3x
add 21 to both sides
27>3x
divide both sides by 3
9>x
x<9
so x= any number below 9 not including 9
