Answer:
21
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
The 2 chords are equal in length so
7x + 5 = 9x - 15
2x = 20
x = 10
I think you mean the greatest common factor to factor
this is useful because say you want to divide 100 by 1000 then the common factor is 100 so factor that out and get 1/10
so just find the factors or the whole numbers that multiply to get those numbers exg
factors of 18=2*3*3
note:2*3 means 2 times 3
so just find the factors and group the common ones exg
896 and 322
factor
896=2*2*2*2*2*2*2*7
644=2*2*7*23
we see that 2*2*7 is common to both so the greatest common factor is 2*2*7=28
Answer : Each grade level will be 30,60,90,30 respectively.
Explanation:
Since we have given that ratio of freshman to sophomores to juniors to seniors in band is 1:2:3:2
Let the number of fresh man be x
Let the number of sophomores be 2x
Let the number of juniors be 3x
Let the number of seniors be 2x
According to question,
x+2x+3x+2x=240
⇒8x=240
⇒x=
⇒x=30
So, the required number of freshman is 30
Number of sophomores is 2×30=60
Number of juniors is 3×30=90
Number of seniors is 2×30=60
