A train running at a speed of 108 km/h crosses a pole in 32 seconds . the length of train is ?

Answers

Answer 1

Answer:

Answer:

Given speed of train = 108 km/hour ⇒ Speed of train = 108 × 5/18 = 30 m/sec Since, we know that Distance = Speed × time ⇒ Distance = 30 × 32 = 960 m ∴ Length of train is 960 m

Step-by-step explanation:

Answer 2

Answer:

Final answer:

The length of the train is calculated by using the formula 'distance = speed * time'. After converting the speed from km/h to m/s, we find that the length of the train is 960 meters.

Explanation:

To answer your question, we'll need to use the concept of speed in physics. Speed is essentially distance covered per unit of time. Since we are given that the train is running at a speed of 108 km/h and it crosses a pole in 32 seconds, we can use these metrics to find the length of the train, as the train length is the distance covered when the train crosses the pole.

First, we need to convert the speed from km/h to m/s, as we need the answer in a standard form. 1 km = 1000 m, and 1 hour = 3600 seconds. So, 108 km/h = 108 * 1000 m/3600 s = 30 m/s.

Next, we use the formula 'speed = distance/time'. Here, we need to find the distance (or the length of the train), so we rearrange that formula to get 'distance = speed * time'. That means, the length of the train = speed of the train * time taken to cross the pole = 30 m/s * 32 s = 960 m.

So, the length of the train is 960 meters.

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

m(x) = 2(x + 4)² - 8 ← is in vertex form

with vertex = (- 4, - 8 ) → A

If two figures are similar, the resulting corresponding angles are always enlarged reduced congruent similar

Answers

If two figures are similar, the resulting corresponding angles are CONGRUENT.

Congruent means exactly equal in size and shape. Congruent angles have the exact same measure.

Two figures are similar when its corresponding angles have the same exact measure.

the answer is congruent. I just took the quiz and I got it right hope this helps!

What is the volume of a cone with a radius of 6 cm and a height of 12 cm? Use 3.14 for pi. Round your answer to the nearest hundredth. (4 points) Group of answer choices 452.16 cm3 465.24 cm3 472.12 cm3 480.50 cm3

Answers

Answer:

The volume of a cone is $452.16\ cm^3$ .

Step-by-step explanation:

We have,

Radius of a cone is 6 cm and its height is 12 cm

It is required to find the volume of a cone. Volume of a cone is given by :

$V=(1)/(3)\pi r^2 h$

r is radius

h is height

Plugging all the given values in the above formula,

$V=(1)/(3)* 3.14*(6)^2* 12\n\nV=452.16\ cm^3$

So, the volume of a cone is $452.16\ cm^3$ .

Answer:

The volume of a cone is kp;m

Change 50% to a decimal, then a fraction. 0.05, 1/20 0.5, 1/2 0.05, 1/2 0.5, 1/20

Answers

Answer:

0.5 and $\frac{1{2}$ .

Step-by-step explanation:

Given : 50%.

To find : change 50% to a decimal, then a fraction.

Solution : We have given Number 50 %

In decimal form

We can convert percentage in to decimal by dividing by 100.

50% = $(50)/(100)$ .

0.5

50% = 0.5.

In fraction form :

$(50)/(100)$ .

On dividing both number by 50

$\frac{1{2}$ .

Therefore, 0.5 and $\frac{1{2}$ .

0.5,1/2 would be the answer
