Answer:
The answer is 40
Step-by-step explanation:
28/x=7/10
firs you need to setup this equation and solve it to get 40
there are 12 girls in the band and 28 boys in the band and I know this because 12+28=40 just like 3/10 + 7/10= 10/10
12 divided by 4 is 3
28 divided by 4 is 7
Find the probability of getting a sum of 35 while rolling 10 number cubes.
we know that
posiible outcomes=6x6x6x6x6x6x6x6x6x6=6^10=60,466,176
To find out the number 35
35=8(4)+2+1
35=6(5)+2+ 1+1+1
35=5(5)+5(2)
35=4(5)+4(3)+2+1
35=3(5)+4(4)+2+1+1
35=5(6)+5(1)
35=4(6)+5(2)+1
35=3(6)+2(5)+2(2)+3(1)
35=2(6)+5+
7x+8x+44.4=180
15x=44.4=180
15x=135.6
x=9.04°
so 8x=72.32° and the 7x is 63.28°
Answer:
12 cleaners
Step-by-step explanation:
8 cleaner can clean in 3 hours = 1 office
1 cleaner can clean in 3 hours = part of job
1 cleaner can clean in 1 hours = part of job
Let the number of cleaner required to finish the job in 2 hours = x
hence
x cleaner can clean in 1 hours = part of job
x cleaner can clean in 2 hours = part of job
Hence
Hence we need 12 men to complete the same job in 2 hours
