Answer:
12/19.
Step-by-step explanation:
There are 19 instructors altogether.
Probability (getting a computer science instructor) = 5/19.
Probability (getting a mathematics instructor) = 7/19.
As this a 'compounded or' probability these values are added so the answer is 5/19 + 7/19
= 12/19.
To figure this out, first subtract the number of kids that rode with their parents; they didn't ride the bus.
375 - 15 = 360
Next, divide 360 by the number of buses there were:
360 ÷ 15 = 24
There were 24 students on each bus.
Terminating decimal
rmember that all numbers can be put over 1 and that is a fraction
ex
1/1=x
3/1=3
π/1=π
so therefor
0.25=0.25/1
if yo want to make the top number equal a whole number
multiply top and bottom by 100 to move 0.25 two decimal places to the right to make it ahwole number
0.25/1 times 100/100=25/100=1/4
answer is 1/4
steps:
1. find how many decimal placees the number goes to (ex. 0.25=2 places 0.2=1 place, 0.2345=4 places)
2. put the decimal over 1 (so if the decimal is x then do x/1)
3. find a fraction that is 10/10 such that the number of zeros one the top should be equal to the zeroes on the bottom, the number of zeros on the top should be equal to the number of decimal places from step 1
4. multiply the fraction (x/1) from step 2 by the fraction from step 3
5. simplify the resulting fraction
Answer:
288
Step-by-step explanation:
the formula is 2(lw+wh+hl)
length - 8
width - 8
height 5
substitute the values and you get
2(64+40+40)
2(144)
= 288
Visible light is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves.
