27.5% of x=11 x is the number of people 27.5%=.275 x=11/.275=40 people in the survey participated
Answer:
Step-by-step explanation:
suface area of base=1/2×9×7.8=9×3.9=35.1 yd²
lateral surface area=3×1/2×9×10=135 yd²
total surface area=135+35.1=170.1 yd²
i assumed it is an equilateral triangular base.
as √(7.8²+4.5²)=9.0049≈9
4.3 bc it’s right and i did the assignment
