what can you explain your question a bit more
Answer:
37.5% are male
62.5% are female
Step-by-step explanation:
in total 120 teachers (45 male+75 female)
therefore:
for male
120 - 100%
45 - x% (we need to find x)
by using the butterfly method (or cross multiply) we get:
120x=100*45
x=4500/120=37.5% (male teachers)
we do the same for female but instead of using 45 we will use 75(the quantity of female theachers in school)
120x=100*75
x=7500/120=62.5%
Answer:
Johnny and his family left home at 10:00.
Step-by-step explanation:
First, You add all of the minutes up,
45+20+10= 75
Then convert the minutes to hours,
75 mins = 1 hr and 15 mins.
Add the hours together,
1 hr + 2 hrs = 3 hrs
Then add minutes,
3 hrs and 15 minutes
Subtract 3 hrs and 15 mins from 13:15,
13.15 - 3.15 = 10:00
Your answer is:
Johnny and his family left home at 10:00.
Answer:
1 5/6 miles
Step-by-step explanation:
3 1/2 - 1 2/3 convert to improper fractions.
7/2 - 5/3 = 21/6 - 10/6 (common denominator)
21/6 - 10/6 = 11/6
11/6 as a proper fraction is 1 5/6
(PV=nrt) Divide nr from both sides to get t by itself. t=PV/nr
