Answer:
n=82
Step-by-step explanation:
Proof:
17+n/3=33
17+82/3=33
99/3=33
33=33
Hope this helps ;) ❤❤❤
Area of a triangle = 1/2 x base x height.
Replace are and base to get:
82.5 = 1/2 x 15 x height
Multiply both sides by 2:
165 = 15 x height
Divide both sides by 15:
Height = 165 / 15
Height = 11 inches.
Step-by-step explanation:
(-1)⁴ - 11 = 1 - 11 = -10
0⁴ -11 = -11
1⁴ - 11 = -10
2⁴ -11 = -3
Answer:
All we have to find the fraction of students who preferred green and go from there.
Subtracting blue and red out of the all students,
1- (1/8+1/4)
1- 3/8
5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5
5/8(2/5) = 3/8
3/8 preferred green, which was 15 students. In order to get 100% of the whole population (1), we multiply by 8/3:
15(8/3) = 40
40 students were surveyed in total.
Step-by-step explanation:
The trapezoid's area is 126 inch².
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
.
Here 
is the lower base and 
is the upper base, height is h.
Step 2:
In the given diagram,
inches and 
inches and h = 9 inches.
inch².
So the given trapezoid's area is 126 inch².
