Answer:
150°
Step-by-step explanation:
We know each angle in a equilateral triangle is 60° and that of a rectangle is 90° . So ,
X = r - h/y ; Solve for h & r
Let's first solve for h :)
Add h/y to both sides.
h/y + x = r
So, r = h/y + x
Now, let's solve for h.
x = r-h/y
Subtract r from both sides.
-r + x = -h/y
Multiply both sides by y.
y(-r + x) = y(-h/y)
Simplify.
-ry + xy = -h
Divide both sides by -1.
ry - xy = h
So, h = ry - xy

Answer:
27π units^2
Step-by-step explanation:
This shape is exactly 3/4 of a full circle. Thus, if we find the area of a full circle with radius 6 units, we multiply the result by 3/4 to obtain the area of the figure shown.
A of full circle = πr²
In this particular case,
A of full circle = π(6 units)² = 36π units^2
Then the area of the given figure is
(3/4)(36π) units^2, or 27π units^2.
Let x be the number of children and t, the number of adults.
x + y =153
5.2x + 8.4y = 1013.2
Solving those equation will give:
x = 85 tickets sold to the kids ( and 68 tickets for adults)
Answer:
15,000 people
Step-by-step explanation:
This is the question of ratio, it is the quantitative relationship of two number.
In this survey a ratio of 66 people out of 110 is defined as living in apartment, based on this ratio we can estimate the total numbers of people living in apartments.
Total population of the town = 25,000 people
Ratio of people living in apartment = 66 / 110 = 0.6
Town people living in apartment = 25,000 x 0.6 = 15,000 peoples
