Area = the top semicircle + the rectangle AEBD
= 1/2 pi*6^2 + 6*12 = 128.55 cm^2 to nearest 100th
Perimeter = 6pi + 12 + 2 pi * 3 = 49.70 cm
-8 you have to do a number line
There are 13 girls and 4 more students that are boys that made an A grade. Thus there are 13+4=17 students that are either girls or A students.
The probability of choosing a girl or A student is 17/30.
You can use the prefixes to figure this out:
Mono: one
Bi: two
Tri: three
So, because there is only one term, it is a monomial.
x= 4.5
18x - 9 = 72 are the equations
Stay safe!! God bless!
