Answer:
Step-by-step explanation:
After 3 hours, Spike charges 6 dollars per hour. For 3 hours, the charge is only $5×3 = $15 (which is $3 less than $6×3). So the rate after 3 hours can be modeled by ...
s(h) = 6h -3
For 8 hours, s(8) = 6·8 -3 = 45 . . . . dollars
__
After 4 hours, Main Deck charges 8 dollars per hour. For 4 hours, the charge is only $18 (which is $14 less than $8×4). So the rate after 4 hours can be modeled by ...
m(h) = 8h -14
For 8 hours, m(8) = 8·8 -14 = 50 . . . . dollars
__
For 8 hours, the $45 charge at Spike's is $5 less than the $50 charge at Main Deck.
Answer:
15 feet per minute.
Step-by-step explanation:
First, convert the units into minutes. If you know that 450 feet is equal to half an hour, or 30 minutes, then to figure out feet per minute, divide 450 by 30. You should get 15 feet per minute.
hope this helps :)
Answer:
( x+3) ^2 + ( y-4) ^2 = 9
Step-by-step explanation:
The equation of a circle can be written as
( x-h) ^2 + ( y-k) ^2 = r^2
Where ( h,k) is the center and r is the radius
( x--3) ^2 + ( y-4) ^2 = 3^2
( x+3) ^2 + ( y-4) ^2 = 9
Answer:
I agree with Helen because she is right that the volume is about 175 cubic inch. and it is a triangular prism.
Step-by-step explanation:
We have a right triangle ( picture is in the attachment ):
tan 52° = h / 41 m
h = 41 m · tan 52° = 41 m · 1.27994 = 52.4776 m ≈ 52 m
Answer:
height of the pyramid is 52 m.
