On the left side, the blank is 22, but I am clueless on the right side
Answer:
13 inches ; 2 inches per hour ; 48 inches
Step-by-step explanation:
Given that :
Inches of snow after 2 hours = 4 inches
Since, snow is falling steadily ;
We can infer that:
Inches of snow per hour : (4 in / 2 hrs) = 2 in / hr
Hence, rate of snow fall = 2in /hr
Inches of snow after 6.5 hours
Rate per hour * Numbee of hours
2 * 6.5
= 13 inches
Amount of snow after x hours :
Rate * x
2 * x
= 2x
Inches of snow after 24 hours
2 * 24 hrs = 48 inches
Answer:
.35 x + .70 (20) = .45(x+20)
50=x
Step-by-step explanation:
Let x = liters of 35% salt solution
We have 20 liters of 70%
We have a total of 20+x liters of 45%
.35 x + .70 (20) = .45(x+20)
Distribute
.35x + 14 = .45x +9
Subtract .35x from each side
14 = .10x +9
Subtract 9 from each side
5 = .10x
Divide each side by .1
5/.1 = x
50=x
From the Pascal's triangle, take the correct level. Use it to write the binomial expansion. Or use nCr.
(x+y)^n
Remember that the powers of x start at n, and that the sum of the x and y powers is always n.
