Hi there, first let's add up the minutes, 30 minutes+15 minutes+20 minutes equals 65 minutes, 65 minutes equals 1 hour and 5 minutes. 7:15 pm, an hour before that is 6:15, 5 minutes before that is 6:10. Therefore, Leo needs to begin at 6:10 pm

PLEASE HELO ME AND EXPLAIN PLEASE. AND PLEASE SHOW IN STEPS!! i will mark brainliest if you get it correct!
Dimas [21]

Step-by-step explanation:

The height of the swipe card is given by :

h(t)=-3t^2+15t+18 .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.

How many feet are in 28 yards?
dsp73

Answer:

84 feet

Step-by-step explanation:

Let the feet be A

1 foot = 0.33 yard

A feet = 28 yards

Cross multiply

A x 0.33 = 28 x 1

Divide both sides by 0.33

A x 0.33/0.33 = 28/0.33

A = 84.84

A = 84 feet

Therefore, there are 84 feet in 28 yards
