The simplified form is 6x-6
Answer:
The % increase is 7.179 but see the remark I made below. What I have given and what it could be is a rounding error. Less than 2 dollars error is not much when you are calculating something for someone just to show them how to do it.
Step-by-step explanation:
242,555 * x/100 = 259,970 Multiply by 100
242,555 * x = 259970 * 100
242,555 * x = 25997000 Divide by 242555
x = 24997000/242444
x = 107.179
That's the total increase.
What you want is 7.179%
If you take 7.179% of 242,555 and add it onto 242555 you should get 259,970
7.1797/100 * 242555 = 17413.02
17413.02 + 242555 = 259968.02
Why isn't it exact. I'm out just about 2 whole dollars. The reason is that the % isn't exact. It's only out to 3 decimal places which apparently is not enough. You can go over my numbers if you want more exactness us use something that is rounded to 7.180 if you like.
Answer:
I believe that the answer is A
Answer:
8 units
Step-by-step explanation:
We can use the distance formula. Recall the distance formula:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Let (-11,7) be
and
, and (-5,1) be
and ![y_2](https://tex.z-dn.net/?f=y_2)
Plug in the numbers:
![d=\sqrt{(-5-(-11))^2+(1-7)^2](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-5-%28-11%29%29%5E2%2B%281-7%29%5E2)
![d=\sqrt{6^2+(-6)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B6%5E2%2B%28-6%29%5E2%7D)
![d=\sqrt{36+36}=\sqrt{72}=6\sqrt2\approx8](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B36%2B36%7D%3D%5Csqrt%7B72%7D%3D6%5Csqrt2%5Capprox8)
3.5 miles per hour. 7/8 (.875) divided by 1/4 (.25) equals 3.5. Hope this helps!
