You can use a volume calculator
The answer is “Yes, Mr. Yule’s sample is random and representative of the population” cause he randomly chose people from all greases
So to find the answer you need to use SOHCAHTOA
Sine= Opposite/ Adjacent
Cosine= Adjacent/Hypotenuse
Tan = opposite/adjacent
angle ADC is 60 so to find the length of line ABC we would use the angle and the line DC.
We would use Tan with opposite over adjacent
Tan 60 = opp. / 5 root 3
opp. = 15
so that is the length of the entire thing, all you need to do now is find the length of the single line of BC which we can use the same equation with just Tan 30 now.
Tan 30 = opp. / 5 root 3
opp. = 5
next you need to take the entire ABC length and subtract the length of BC to get AB
15-5 = 10
so the answer would be C
Answer:
10g-12
Step-by-step explanation:
9(x + 3) = 108
First distribute the 9 to everything inside the parenthesis by multiplying them.
9x + 27 = 108
Now subtract 27 from both sides
9x + 27 (-27) = 108 (-27)
9x = 81
divide 9 from both sides
9x/9 = 81/9
x = 9
9x = 81
hope this helps
