The width of a rectangle is two-thirds of its length, and its area is 216 square meters. What is the length? is it 27 or 12

Answers

Answer:

The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle = $(2)/(3)x$

Area of rectangle = $216 m^2$

We have to find the length of rectangle .

Area of rectangle = $length* breadth$

Substitute the values in the given formula

$216=x* (2)/(3)x$

$216=(2)/(3)x^2$

$2x^2=216* 3$ By multiplication property of equality

$x^2=(216* 3)/(2)$ ( by division property of equality )

$x=√(324)=18$

Substitute the value then we get

Width of rectangle = $(2)/(3)* 18=12 m$

Hence, the length of rectangle =18 m.

The tub of a washer goes into its spin cycle, starting from rest and gainiing angular speed steadily for 8.0 s when it is turning at 5.0 rev/s. At this time the person doing the laundry opens the lid and a safety switch turns off the washer. The tub smoothly slows to rest in 12.0 s. Through how many revolutions does the tub turn whil it is in motion.

Answers

Angular acceleration is change of angular velocity over time:
α = 5 / 8 = 0.625 rev / s²
Number of revolutions of the 1st part:
α · t² /2 = 0.625 * 8² / 2 = 20 rev.
The 2nd part:
α = 5/12 = 0.41667 rev/s²
5 * 12 - ( 0.41667 * 12² / 2 ) = 60 - 30 = 30 rev.
In total: 20 + 30 = 50 revolutions

If a rhino stampede runs at about 13.5 m/s. if they went 77 how long would it take them in seconds?

Answers

Answer:

5.7 seconds

Step-by-step explanation:

Lets assume that 77 has units of meters (m).

The expression the relates time(T), speed(S), and distance(D) is:

D = S*T

We are given S = 13.5 m/s and D = 77m

D = S*T

77m = (13.5 m/s)*(T)

T = (77 m)/(13.5 m/s)

T = 5.7 seconds

Final answer:

To find the time it would take for a rhino stampede running at a speed of 13.5 m/s to travel 77 meters, we use the formula Time = Distance/Speed, which gives us a result of approximately 5.7 seconds.

Explanation:

This is a classic physics problem where you are asked to calculate the time. The question is asking for the time it would take for a rhino stampede running at a speed of 13.5 m/s to reach a certain distance, which is 77 meters.

To find the time, you need to use the formula for time, which in terms of speed and distance is: Time = Distance/Speed.

Step 1: Plug in the given values into the formula. So Time = 77m / 13.5 m/s.

Step 2: Do the division. The result comes out to be around 5.7 seconds. Therefore, it will take about 5.7 seconds for the rhino stampede to reach 77 meters.
