If 5 in 25 people make a preorder, the remaining people in that study group did not. By subracting the people who pre-ordered from the total people the people without preorders will be found
People without preorders = 25-5 =20
20 people didn't preorder
Answer:
X=6 and Y=3
Step-by-step explanation:
Use SOHCAHTOA, SOH, Sin=Opposite/Hypotenuse, Therefore Sin60°=(3√3)/x ; Xsin60°=3√3 and Sin60° without using 4figuretable or calculator is √3/2, Now x=3√3 ÷√3/2 ;. therefore X=3√3×2/√3= 6. X=6 . Using Pythagoras theorem, 6²={(3√3)² +y²}. Y²= 36-27=9. Y=√9, Y=3. Therefore X=6 and Y=3.
Answer:
yes
Step-by-step explanation:
First find the number of mysteries by multiplying 85 books by 20%:
80 x 0.20 = 17
Now add mysteries and adventure books together and subtract from 85 to find the number of fantasy books:
17 + 18 = 35
85 - 35 = 50
So 50 out of 85 books are fantasy.
This is written as 50/85 which simplifies to 10/17.
