Answer:
1. 50 is 20% of 250
Step-by-step explanation:
In order to find any of these, use the equation.
Number/Out of = %
Then plug in the values
50/x = .20
Then solve by cross multiplying
50 = .20x
250 = x
Answer:
100 beats per minute
Step-by-step explanation:
If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.
To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:
28.8 secs = 48 beats
60 secs = x beats
Cross multiply
28.8*x = 60*48
28.8x = 2,880
Divide both sides by 28.8
x = 2,880/28.8
x = 100
✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM
<span>With a boys to girls ratio of 8:7, this means 8/15 of the campers are boys and 7/15 of the campers are girls.
We are told that there are 195 total campers.
To find # of boys: 195 (the total # of campers) x 8/15 (fraction of the campers that are boys) = 104 boys
To find # of girls: 195 (total # of campers) x 7/15 (fraction of the campers that are girls) = 91 girls
Note: If you do not know how to multiply by fractions, let me know, I have another trick that takes more time but doesn't require the use of fractions.

Answer:
Athena = 10,265 km
Vesta = 102,650 km
Juno = 102,650 km
Ceres = 2,053,000 km
Apollo = 1,026,500 km
Step-by-step explanation:
Athena = 20,530 / 2 = 10,256
From there, you can work out the rest by multiplying accordingly.
Hope this helps and made sense! :)
