Answer:
100000
Step-by-step explanation:
10x10x10x10x10= 100000
Given:
![|x-4(72)|=2](https://tex.z-dn.net/?f=%7Cx-4%2872%29%7C%3D2)
To find:
The highest and lowest scores Sam could have made in the tournament.
Solution:
We have,
![|x-4(72)|=2](https://tex.z-dn.net/?f=%7Cx-4%2872%29%7C%3D2)
![|x-288|=2](https://tex.z-dn.net/?f=%7Cx-288%7C%3D2)
It can be written as
![x-288=\pm 2](https://tex.z-dn.net/?f=x-288%3D%5Cpm%202)
Add 288 on both sides.
![x=288\pm 2](https://tex.z-dn.net/?f=x%3D288%5Cpm%202)
and ![x=288+2](https://tex.z-dn.net/?f=x%3D288%2B2)
and ![x=290](https://tex.z-dn.net/?f=x%3D290)
Therefore, the highest and lowest scores Sam could have made in the tournament are 290 and 286 respectively.
Answer:
8
Step-by-step explanation:
We have, 25% × x = 200
or,
25
100
× x = 200
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 200 ×
100
25
x = 800
If you are using a calculator, simply enter 200×100÷25, which will give you the answer.
So now that you have the original number you just need to find 1% of 800
1% of 800 is 8
