60 is 25% of what number

Answers

For these problems,  the this number is this percent of what number ones,  turn the percent into a decimal.
Do this by moving the decimal two places to the left.
0.25 is the decimal.
Now divide the whole number by the decimal.
60/0.25=240
60 is 25% of 240
Solutions 
To solve the problem we first have to turn the percent into a decimal. To convert to decimal divide the percent by 100. 

0.25 is the decimal.

Now divide the whole number by the decimal.

60÷ 0.25 = 240

60 is 25 percent of 240

Melinda, a carpet installer, brings 270 square feet of carpet padding on an installation job. After the job is finished, she has 1⁄5 of the carpet padding left over. How many square feet of carpet padding did Melinda use? A. 230
B. 54
C. 216
D. 244

Answers

A correct option is an option (B).

Given,

The total area of the carpet is 270 square feet.

Fraction:

it is also termed as a portion or section of any quantity. It is denoted by using the ‘/’ symbol, such as a/b. For example, 2/4 is a fraction where the upper part denotes the numerator and the lower part is the denominator. A fraction is a word that is originated from Latin. In Latin, “Fractus” means “broken”.

Now, (1)/(5) of the carpet padding leftover.

So, (1)/(5) of 270 square feet is,

(1)/(5) *270=54

So, 54 square feet is left.

Answer:

c     216

Step-by-step explanation:

270 divide by 5 equals 54

54 times 5 equals 270

270 - 54 equals 216

An automobile traveling 95 km/h overtakes a 1.00km long train travelling in the same direction on a track parallel to the road. if the train's speed is 75km/h, how long does it take the car to pass it and how far will the car have traveled in this time? what are the results if the car and train are traveling in opposite directions?

Answers

Lovely.

The car is traveling at 95 km/h, and the train is at 75 km/h.

Remember the train is 1 km long.

a)

With respect to the train the car is not moving as much as 75 km/h.

The car with respect to the train is moving as much as 95 - 75 = 20 km/h

Recall the train is 1 km long.

Time to cover the 1km long train = Distance / speed = 1 / 20 = (1/20) hour.

= (1/20)*60 minutes = 3 minutes.

So the car would pass the train in 3 minutes.    

b)

Now if they are traveling in opposite directions;

the car with respect to the train = 75 + 95 = 170 km/h

Time to cover the 1km long train = Distance / speed = 1 / 170 = (1/170) hour.

= (1/170)*60 minutes = (6/17) minutes 

= (6/17)*60 seconds = 360/17 seconds ≈ 21.176 seconds.

SameDirection: The car takes 3 minutes to pass the train and travels 4.75 km in this time.

Opposite Directions: The car takes about 0.35 minutes to pass the train and travels approximately 559 meters in this time.

SameDirection:

When the car overtakes the train, it has to cover the entire length of the train, which is 1.00 km.

Relative speed of the car with respect to the train = Car's speed - Train's speed

Relative speed = 95 km/h - 75 km/h

= 20 km/h

Now, we can calculate the time it takes for the car to overtake the train:

Time = Distance / Relative speed

Time = 1.00 km / 20 km/h

Time = 0.05 hours

=3 minutes(since 1 hour = 60 minutes, this is 0.05 x 60 = 3 minutes)

Hence, it takes the car 3 minutes to pass the train when they are traveling in the same direction.

Now, let's calculate how far the car has traveled in this time:

Distance traveled by the car = Car's speed x Time

Distance traveled by the car = 95 x 0.05

Distance traveled by the car = 4.75 km

So, when the car overtakes the train while traveling in the same direction, it takes 3 minutes, and the car will have traveled 4.75 km in that time.

Opposite Directions:

When the car and train are traveling in oppositedirections, they are moving towards each other.

In this case, the relative speed will be the sum of their speeds.

Relative speed of the car and train = Car's speed + Train's speed

Relative speed = 95 km/h + 75 km/h

= 170 km/h

To calculate the time it takes for the car to pass the train:

Time = Distance / Relative speed

Time = 1.00 km / 170 km/h

Time = 0.005882 hours (approximately 0.35 minutes)

So, it takes the car about 0.35 minutes to pass the train when they are traveling in opposite directions.

Now, let's calculate how far the car has traveled in this time:

Distance traveled by the car = Car's speed x Time

Distance traveled by the car = 95 km/h x 0.005882 hours

Distance traveled by the car = 0.5588 km (approximately 559 meters)

Hence, when the car and train are traveling in opposite directions, it takes about 0.35 minutes, and the car will have traveled approximately 559 meters in that time.
