Answer:
Step-by-step explanation:
If there are 1500 total students.
75% or 1125 are boys
25% or 375 are girls.
So, we know that the amount of wrapping paper necessary is equal to the surface area or net of the box.
Solve for the surface area of the box.
First side: <em />8*6=48
Second side: 8*6=48
Third side: 6*5=30
Fourth side: 6*5=30
Fifth side: 5*8=40
Sixth side: 5*8=40
Now, add up the areas of the sides.
48+48+30+30+40+40=236 inches
Answer:
Height of the antenna = 28 ft (Approx)
Given:
Length of base = 300 ft
Angle of elevation to the building = 40°
Angle of elevation to the antenna = 43°
Find:
Height of the antenna
Computation:
Using trigonometry function:
Tan40° = Height of building / Length of base
Height of building = 251.73 ft
Tan43° = [Height of building + Height of the antenna] / Length of base
0.9325 = [251.73 + Height of the antenna] / 300
Height of the antenna = 28.02 ft
Height of the antenna = 28 ft (Approx)
Answer:
Median- 31
Mean- 39
Mode- 20
Range-71
Step-by-step explanation:
Median-13, 20, 20, 20, 31, 35, 61, 67, 84
31 one is in the middle, also you have to sort it for least to greatest.
Mean- Add all the number then divide by the numbers there are.
Mode-It has occored the most
Range- sort least to greatest, then subtract the highest number to the lowest
