Answer:
$120
Step-by-step explanation:
100x30=3000
4x30=120
Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α

Answer:
1.) can not be found
2.)V=11403.98
3.)
Step-by-step explanation:
volume = π r×r × H
r = Radius
H = height
π = 3.14
the first one does not have a radius so therefore we can NOT find the volume
the second one is π×(11×11) ×30 =11403.98
the 3rd one is π× (10×10) ×5 =1570.79
hope this helped
Answer:
The last graph best represents the story
Step-by-step explanation:
Mary left for school from rest. So the initial speed is zero.
So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.
When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.
After resting she still continued her journey to school.
This part also has a positive slope.

Answer:
x = -3/2
Step-by-step explanation:
The zeros of the function are the values of x that make the factors zero:
x = -4, x = 1
The axis of symmetry is the vertical line halfway between these zeros.
x = (-4 +1)/2 = -3/2
The equation of the axis of symmetry is x = -3/2.
