A parking garage has 9 floors, including the street level, with 8 separate ramps connecting them. Each ramp is 18 m in length and the top floor is 28 m above street level.
a. Assuming each ramp has the same dimensions, what is the slope of each ramp? (2
marks)
b. Stairs rise from the street level to the top floor. The stairwell between the street level
and the first floor has the same rise as one ramp. The slope of the stairwell is 0.95. What
horizontal distance does the stairwell cover? (2 marks)

20335+282=20617

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

if you was gonna solve for a, a is a   < -12

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
