A bicycle-sharing station on Main Street has 5 times as many bicycles as a station on Park Avenue. There are 24 bicycles at the two stations. How many bicycles are at the Main Street station?​

Answers

Answer 1

There are 20 bicycles at the Main Street station.

According to question statement, A bicycle-sharing station on Main Street has 5 times as many bicycles as a station on Park Avenue. There are 24 bicycles at the given two stations.

We are supposed to know the number of bicycles at the Main Street station.

Let us assume that the number of bicycles at the Park Avenue station is "x". Then, number of bicycles at the Main Street station will be "5x".

We will have to form a Linear Equation of single variable "x" as per the conditions based in the question statement, and solving for x, we will obtain our desired answer.

As there are 24 bicycles at the two stations therefore,

[tex]x + 5x = 24[/tex], will be our equation.

Solving the equation for x, we get

[tex]x + 5x = 24\\6x = 24\\x=\frac{24}{6} \\or x=4[/tex]

Therefore the number of bicycles at the Park Avenue station is 4.

And the number of bicycles at the Main Street station will be 5x i.e., [tex]5*4 = 20[/tex].

Find the scale if:

Answers

The scale used on the map is 1 centimeter to 12.5 kilometers.

How to find the scale?

When we do a scale drawing of something in scale (like a map, that represents a given location) the dimensions suffer a change of scale.

This means that each unit on the scale drawing not represents the same unit on the original thing.

On this case we have a map where a actual distance of 50 kilometers is represented by a distance of 4cm (this means that each 4cm in the map are equivalent to 50 kilometers in the actual place).

Then the scale will be in cm to km, and to get the scale we can write:

4cm = 50km

Dividing both sides by 4 we get:

1cm = 50km/4 = 12.5 km

Then we conclude that the scale used for the map is 1 centimeter to 12.5 kilometers.

There are 496 black sedans in the parking lot and 640 non-black sedans in the parking lot. What is the ratio of non-black sedans to black sedans

Answers

Answer: the ratio is 1.13

Step-by-step explanation:

The ratio of non-black sedans to black sedans is 40/31, as of the given condition.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,

The total number of sedans in the parking lot is,
496 black sedans + 640 non-black sedans = 1136 sedans.

The ratio of non-black sedans to black sedans can be found by dividing the number of non-black sedans by the number of black sedans:

Ratio = 640 non-black sedans / 496 black sedans
Ratio  = 640/496

Answers

Option one, it is a 15.6069% increase

The percentage increase is the ratio of value increased to the original value and multiplied by 100.

The percentage increase in his hourly wage between year 1 and year 2 is 15.61%.

Option A is the correct answer.

What is a percentage increase?

The percentage increase is the ratio of value increased to the original value and multiplied by 100.

It is expressed in percentage.

If there is an increase in the value of anything, then there is an increase in percentage.

We have,

Wage in the first year per hour = $8.65

Wage in the second year per hour = $10

The percentage increase in hourly wage:

= [ (10 - 8.65) / 8.65 ] x 100

= ( 1.35 / 8.65 ) x 100

= 15.6069 %

= 15.61 %

Thus the percentage increase in his hourly wage between year 1 and year 2 is 15.61%.

In the question, it is given that city A is 96 feet below sea level, city C is 24 feet below sea level, and the elevation of city D is 1 over 4th of the elevation of C. Since, City A & C are both below sea level their elevation will be negative. So, by these we get elevations:

In the beginning, they used an hourglass. This is a cylindrical glass with a narrow center which allows sand to flow from its upper to its lower portion. Once all the sand has trickled to the lower portion, one knows that an hour has passed. Using the same idea, water clocks were constructed to measure time by having water flow through a narrow passage from one container to another. On the other hand, sundials allowed people to estimate an hour by looking at the position of the shadow cast by the sun on a plate. At night, people measured time by checking the alignment of the stars in the sky. None of these were accurate, though.
