Since you know that the hose will fill the whole pool in 8 minutes you know it will fill 1/8 of the pool per minute. In 5 minutes it will fill up 5/8 of the pool. This will make your equation 5/8 +5r=1. Solving for r will give you 3 parts/40 minutes
The <u><em>correct answer</em></u> is:
(8, 20).
Explanation:
We can substitute the values for x in the equation and see if they equal y:
y=16+0.5(0) = 16+0 = 16 ≠ 18. This is not the correct option.
y=16+0.5(5) = 16+2.5 = 18.5 ≠ 19.5. This is not the correct option.
y=16+0.5(8) = 16+4 = 20. This is the correct option.
Answer:
Step-by-step explanation:
245000 last year
This year 25235
(y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
(( £25.235 - £24.500) / £24.500) * 100 = 0 %
There ain't no percentage change as there needs to be a bigger difference between the two numbers plus u should use the formula
Given:
standard deviation = 4.3%
sample size = 15
mean = 26.4%
error = σ/√n
error = 4.3% / √15
error = 4.3% / 3.873
error = 0.0111
0.0111 x 100% = 1.11%
Answer:
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Step-by-step explanation:
Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:
37 = x + (x+ 7) + (x + 6)
37 = 3*x + 13
3*x + 13 = 37
3*x = 37 - 13
3*x = 24
x = 24 / 3
x = 8
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
