Andreyy893 years ago
7 0

Answer:

the number of boxes that would take fill

the storage completely is 6<u>0 boxes.</u>

Step-by-step explanation:

given:

A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.

find:

What number of

1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely

fill this storage unit?

Volume of a storage unit = 6 x 7.5 x 4.5

Volume of a storage unit = 202.5  ft³

Volume of a cardboard box = 1.5 x 1.5 x 1.5

Volume of a cardboard box = 3.38 ft³

to get the number of cardboard boxes to fill in the storage unit,

Number of boxes =  <u>   202.5 ft³  </u>  

                                     3.38 ft³

Number of boxes = 60

therefore,

the number of boxes that would take fill the storage completely is 60 boxes.

The blades of a windmill turn on an axis that is 40 feet from the ground. The blades are 15 feet long and complete 3 rotations e
astraxan [27]

Answer:

a is the _amplitude_(Length of the blades)_

The vertical shift, k, is the _Mill shaft height_

a = 15\ ft\\\\k = 40\ ft

y = 15sin(\frac{\pi}{10}t) + 40

Step-by-step explanation:

In this problem the amplitude of the sinusoidal function is given by the length of the blades.

a = 15\ ft

The mill is 40 feet above the ground, therefore the function must be displaced 40 units up on the y axis. So:

k = 40\ ft

We know that the blades have an angular velocity w = 3 rotations per minute.

One rotation = 2\pi

1 minute = 60 sec.

So:

w = \frac{3(2\pi)}{60}\ rad/s

w = \frac{\pi}{10}\ rad/s

Finally:

a is the _amplitude_(Length of the blades)_

The vertical shift, k, is the _Mill shaft height_

a = 15\ ft\\\\k = 40\ ft

y = 15sin(\frac{\pi}{10}t) + 40

Kevin and Michelle traveled together by car and shared the driving. Kevin drove for 3.25 hours, then Michelle drove for 1.5 hour
jek_recluse [69]

Using the relation of velocity, distance and time, it is found that 35 represents Michelle's velocity.

-----------------------------

Velocity is <u>distance divided by time</u>, then:

v = \frac{d}{t}

Kevin drove for 3.25 hours, thus t_1 = 3.25. The distance drove by Kevin is:

d_1 = v_1t_1

d_1 = 3.25v_1

Michelle drove for 1.5 hours, thus t_2 = 1.5. The distance drove by Michelle is:

d_2 = v_2t_2

d_2 = 1.5v_2

The total distance is:

d = d_1 + d_2

d = 3.25v_1 + 1.5v_2

Comparing to the expression:

3.25v_1 + 1.5v_2 = 3.25(42) + 1.5(35)

We get that 42 is Kevin's speed and 35 is Michelle's speed.
