Kevin loves the new video game rental store and he has a membership. When Kevin rented 2 games, he had spent a total of $25 of h

sveticcg [70]

Answer:

Step-by-step explanation:

Let x represent the number of video games that Kevin rents.

Let y represent the total amount that he paid for x video games rental.

The slope intercept form of an equation is expressed as

y = mx + c

Where

m = slope

c = intercept

When Kevin rented 2 games, he had spent a total of $25 of his money. When Kevin rented 2 more video games (4 total), he then had spent $30 total of his money at this store all together. Therefore,

Slope, m = (30 - 25)/(4 - 2) = 5/2 = 2.5

To determine the intercept, c, we will substitute m = 2.5, x = 4 and y = 30 into y = mx + c. It becomes

30 = 2.5 × 4 + c

30 = 10 + c

c = 30 - 10 = 20

The Slope-Intercept Form to model how much Kevin pays per x video game rentals with his store membership becomes

y = 2.5x + 20

The cost per video game rental is $2.5

The membership fee is $20

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36

Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = $7.02576 * 10^6$

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in $7.02576 * 10^6$ minutes is calculated as follows

Number of days = $\frac{7.02576 * 10^6}{1440}$

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are $\frac{4879}{30}$ months in 4879 days

Number of months = $\frac{4879}{30}$

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are $\frac{4879}{365}$ years in 4879 days

Number of years= $\frac{4879}{365}$

Number of years = 13.37 years

A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initial

faltersainse [42]

Answer:

$y=12.5x+225$

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the amount of fuel in gallons

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the unit rate or slope

b is the y-intercept or initial value

we have that

The unit rate or slope is equal to

$m=12.5\ \frac{gal}{min}$

$b=225\ gal$ ----> initial value (value of y when the value of x is equal to zero)

substitute

$y=12.5x+225$
