Answer:
4/27
Step-by-step explanation:
The laws of exponent are used for the simplification of expressions with exponential powers. Considering the given expression, the applicable laws of exponents are
a^-x = (1/a)^x
and
a^(x/b) = b√a^x
Hence
9-3/2 · 82/3
= (1/9)^3/2 . 8^2/3
= √(1/9)³ . ∛8²
= (1/3)³ . 2²
= 1/27 . 4
= 4/27
<span>8 ≥ 16y
Divide both sides by 16.
0.5 </span>≥ y, or y ≤ 0.5.
The answer is A) y ≤ 0.5.
Answer:
2.68 pints
Step-by-step explanation:
The fraction of white paint is 1 -3/5 = 2/5, so the quantity of white paint is ...
(2/5)(6.7 pints) = 2.68 pints
Kimberly used 2.68 pints of white paint.
Answer: 91 students ride the bus
For this problem, you can set up a proportion where:
w = those who walk to school
r = those who ride the bus to school
![\frac{w}{r} = \frac{w}{r}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bw%7D%7Br%7D%20%20%3D%20%20%20%5Cfrac%7Bw%7D%7Br%7D%20)
Then include the ratio (1:7) as a fraction (1/7) and the value that is known (13).
![\frac{1}{7} = \frac{13}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B13%7D%7Bx%7D%20)
Cross multiply (create an "x").
![1 \times x = 7 \times 13](https://tex.z-dn.net/?f=1%20%5Ctimes%20x%20%3D%207%20%5Ctimes%2013)
![x = 91](https://tex.z-dn.net/?f=x%20%3D%2091)
Lol... I don't know if this is a joke, but it's basically just restating the precious problem, but switching numbers. So the answer would be 2,592.
