Answer:
Speedie ran the race in 0.708(3)% of an hour, the 3 in the parentheses means the 3 repeats forever
Step-by-step explanation:
We have 25.5/3600, and when we convert it to a decimal, we have 0.00708(3), the 3 in the parentheses means the 3 repeats forever. To convert it to percentage, we multiply it by 100, to get 0.708(3). Hope it helps!

Answer:
<u>y=6x-4</u>
Step-by-step explanation:
<u>What we know</u>
- the slope is 6
- our point is (-9,-58)
-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this
-58=6(-9)+b
-58=-54+b
-58=54+b - we changed -54 to a positive 54
54-58=-4
y=6x-4
Step-by-step explanation:
The solid figure that it represents is a A) cube
Answer:
![x=\frac{132}{25}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B132%7D%7B25%7D)
Step-by-step explanation:
We have to solve for the value of "x". The equation is:
![\frac{1}{3}(12+x)=8(6-x)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%2812%2Bx%29%3D8%286-x%29)
We can use the distributive property shown below to simplify the expression and find the value of x.
<u>Distributive property:</u> ![a(b+c)=ab+ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%3Dab%2Bac)
Now, we solve:
![\frac{1}{3}(12+x)=8(6-x)\\4+\frac{1}{3}x=48-8x\\\frac{1}{3}x+8x=48-4\\8\frac{1}{3}x=44\\\frac{25}{3}x=44\\x=\frac{44}{\frac{25}{3}}\\x=44*\frac{3}{25}\\x=\frac{132}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%2812%2Bx%29%3D8%286-x%29%5C%5C4%2B%5Cfrac%7B1%7D%7B3%7Dx%3D48-8x%5C%5C%5Cfrac%7B1%7D%7B3%7Dx%2B8x%3D48-4%5C%5C8%5Cfrac%7B1%7D%7B3%7Dx%3D44%5C%5C%5Cfrac%7B25%7D%7B3%7Dx%3D44%5C%5Cx%3D%5Cfrac%7B44%7D%7B%5Cfrac%7B25%7D%7B3%7D%7D%5C%5Cx%3D44%2A%5Cfrac%7B3%7D%7B25%7D%5C%5Cx%3D%5Cfrac%7B132%7D%7B25%7D)
This is the improper fractional value of "x". So,
![x=\frac{132}{25}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B132%7D%7B25%7D)
