Answer:
Step-by-step explanation:
Let
y ----> the total cost for renting the popcorn machine
x ----> the time in hours
we know that
The total cost of renting a popcorn machine for 6 hours is $48
so
using proportion
Find out the total cost for renting the popcorn machine for x hours
Is a linear direct variation
The constant of proportionality or slope is equal to
That means ----> the total cost is $8 per hour
Answer:
7.7 seconds
Step-by-step explanation:
To find how long would take to the object fall to the ground from the top of the building, we just need to use the function given (which express the position of the object in a certain time):
s(t) = 16*t2
The height of the tower is 949 feet, so the total height the object will fall is 949 feet. Using this value for s(t), we can find the value of t (the total amount of time that will take to travel this distance):
949 = 16*t2
t2 = 949 / 16
t2 = 59.3125
t = 7.7015 seconds
So it would take 7.7 seconds for the object to fall to the ground from the top of the building.
Answer:
115.2 in²
Step-by-step explanation:
Area of two triangles =
4 x 3 = 12
Area top rectangle/parallelogram =
5 x 8.6 = 43
Area back rectangle =
3 x 8.6 = 25.8
Area bottom rectangle =
4 x 8.6 = 34.4
Total = Sum of all areas
115.2 in²

Answer:
Jamie must sprint 107 meter to pass Shelly at point A.
Step-by-step explanation:
Circumference of a sector of the circle is represented by,
Circumference =
where θ = central angle subtended at the center by an arc
r = radius of the circle
=
= 34.1667π
= 107.34 meter
≈ 107 meter
Therefore, Jamie must sprint 107 meter to pass Shelly at point A.
