10 is another way to say 1,000. So. just do the stuff by thinking like.. 1
10 is 10, 2
10 is 100. so on and so on. Hope this helped.
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%
Two angles are complementary when they add up to 90 degrees<span>
</span>Two angles are supplementary when they add up to 180 degrees
angle = x
supplementary angle = (180-x)
complementary angle = (90-x)
180 - x - 40 = 2(90-x)
140 - x = 180 - 2x
-x + 2x = 180 - 140
x = 40°
