6 buses with 32 students per bus.....6 x 32 = 192 students
each row seats 8 students...192/8 = 24 rows will be needed for all students
Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
Longer wavelength means lower frequency (lower pitch)

The scale factor (k)
Since point C is the center of dilation, the scale factor (k) is calculated using:

So, we have:



Answer:
K = (1/2)r^2(sin(θ) +θ)
Step-by-step explanation:
The area of the triangle to the left is ...
A1 = (1/2)r^2·sin(180°-θ) = (1/2)r^2·sin(θ)
The area of the sector to the right is ...
A2 = (1/2)r^2θ
so the total area of the blue shaded region is ...
K = A1 + A2 = (1/2)r^2·sin(θ) + (1/2)r^2·θ
K = (1/2)r^2(sin(θ) +θ)
