Step-by-step explanation:
There are several which in which we can approach this question:
We can do this question using direct proportion.
"If 18 girls represent 60%, how many students represent 100%?"
18
60
=
x
100
x
=
18
×
100
60
30
students altogether.
To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
damp everyone is giving exams lol
Based on the result of the girl experiment, we can predict that if the same coin is tossed again as an independent experiment,
