Answer:
63 people
Step-by-step explanation:
Given parameters:
Number of students survey = 32
Number of those that liked ice-cream = 8
Total population size = 252
Unknown:
How many people in the population should prefer ice cream = ?
Solution:
From the survey;
8 out of 32 students prefer ice cream;
8 : 32
1: 4
This shows that 1 out of 4 students will prefer ice cream
NOw to the total population;
If out of 4 students, 1 prefers ice-cream;
Out of 252 students y will prefer ice-cream
Number of students that prefers ice-cream =
= 63people
The correct answer is 13.86.
In order to find this, we must first note that the tangent of any angle is equal to the opposite side length over the adjacent side length. If we use that formula and the 60 degree angle, we can find y.
Tan(angle) = Opp/Adj
Tan(60) = y/8
8Tan(60) = y
13.86 = y
I saw the image that accompanied this problem.
4 identical isosceles trapezoid forming 2 parallelogram.
1 parallelogram has a base of 16 inches and its height is 10 inches.
We need to get the area of the parallelogram and multiply it by 2 before dividing it into 4 to get the area of each isosceles trapezoid.
Area of a parallelogram = base * height
A = 16 in x 10 in = 160 in²
160 in² x 2 parallelogram = 320 in²
320 in² / 4 tiles = 80 in²
The area of one tile is 80 square inches.
I can’t understand any of this but I have to answer stuff
