Answer: b. b^9
Step-by-step explanation:
1. You can rewrite ![\sqrt[3]{b^{27}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bb%5E%7B27%7D%7D)
as following:
Because, by definition ![\sqrt[n]{x}=x^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
2. Now, keeping on mind the exponents properties, you can multiply the exponents, then you obtain:
3. Finally, you must simplify the exponent, then, you obtain the following result:
Answer: 75 people
Step-by-step explanation:
1).
we have percentage of people who invested in 18-29 year category
=31%
we need
n=40 people
this is
30% of x =40
or
0.3x=40
x=40/0.3 =133.33 or 134 people
2).
in 65+ category
percentage =54%
we need
n=40
this is
54% of x =40
or
0.54x=40
or
x=40/0.54 =70.07 or 75 people
Answer:
ithink it should be c
Step-by-step explanation:
Answer: The answers are:
6 + 2 = 8
4 + (-1) = 3
Step-by-step explanation:
Add 6 by 2.
Solve for X.
4 + X = 3
To find X, we use the integer rule. We can use this:
Positive and Positive = Positive
Negative and Negative = Negative
Positive and Negative = Both (It depends if the negative or positive is larger than the other)
For this problem, we can use: Positive and Negative = Both.
If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).
4 is greater than -1
4 > -1
Therefore, X equals -1.
4 + (-1) = 3
