It's an 11% increase. To find this, you have to subtract 85 from 94.35 and then you divide that difference by the original amount. In this case it's 85. After that, you get .11. Then you just turn it into a percent.
Let x be the number.
Then the equation can be written as
3 -2x = x +8
It is 50! Hope this helps.
Answer:
4√2
Step-by-step explanation:
If a square has a perimeter of 16, then its side lengths are 4.
Use the pythagorean theorem to find the diagonal.
- 4^2+4^2=c^2
- 16+16=c^2
- 32=c^2
- c=√32
√32 can be simplified to 4√2.
Answer:
56 total
Step-by-step explanation:
Let the number of girls = x
Let the number of boys = 3x
x 1
=== = ==========
x + 28 3
Cross multiply
3x = x + 28 Subtract x from both sides
3x - x = 28 Combine
2x = 28 Divide by 2
x = 28/2
x = 14
Girls = 14
Boys = 14 + 28 = 42
Is the ratio 3 to 1?
42/14 = 3/1 Yes it does
Total number
14 + 42 = 56
