Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes
Answer: approximately 5.5814 calories
==================================
We start off with this ratio
4.3 ounces : 24 calories
Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side
4.3 ounces : 24 calories
4.3/4.3 ounces : 24/4.3 calories
1 ounce : 5.5814 calories
This value is approximate to four decimal places.
Answer:
540, 541, 542
Step-by-step explanation:
let the number be n
hence the 3 consecutive numbers may be expressed as:
n , n+1, n+2
it is given that the sum of the 3 numbers is 1623
hence,
n + (n+1) + (n+2) = 1623
n + n + 1 + n + 2 = 1623
3n + 3 = 1623
3n = 1623 -3
3n = 1620
n = 1620 / 3
n = 540
hence the numbers are
540, (540 + 1) , (540 + 2)
or
540, 541, 542
