A gas station has monthly expenses in dollars of 5000+2.2 X. It sells the gas at $2.25 per gallon. How many gallons do they need to sell to make a profit of $3000 per month

Answers

The number of gallons to be sold in a month is 160,000 gallons.

Your question is incomplete. It looks like you are referring to this question below:

A gas station has monthly expenses in dollars of 5000+2.2 X. It sells the gas at $2.25 per gallon. How many gallons do they need to sell to make a profit of $3000 per month, if X is the number of a gallons sold.

The given parameters include;

total monthly expenses, t = $(5000 + 2.2x)

number of gallons sold,  = x

price of a gallon, p = $2.25

estimated profit in a month, g = $3000

The equation for profit made in a month is as follows;

Total revenue - expenses = profit

2.25x - (5000 + 2.2x) = 3000

2.25x - 5000 - 2.2x = 3000

0.05x = 8000

x = 8000/0.05

x = 160,000 gallons

Therefore, the number of gallons to be sold in order to make the estimated profit in a month is 160,000 gallons.

if 2x+20 and 3x+20 makes a straight angke find value of x​

Answers

Answer:

x = 28

Step-by-step explanation:

The sum of the angles in a straight angle = 180°

Sum the angles and equate to 180

2x + 20 + 3x + 20 = 180

5x + 40 = 180 ( subtract 40 from both sides )

5x = 140 ( divide both sides by 5 )

x = 28

From the picture, we are to draw the graph of the function

[tex]y = -\frac{4}{x}[/tex] for the range of values [tex]-3\leq x\leq 3[/tex] (that is for values of x from -3 to 3)

The graph for the function [tex]y = -\frac{4}{x}[/tex]  (purple lines) is also shown in the attachment.

To use the graph to solve the equation [tex]\frac{4}{x}-2x+1=0[/tex]

We will rewrite the equation so that it takes the form [tex]y = -\frac{4}{x}[/tex]

From [tex]\frac{4}{x}-2x+1=0[/tex]

Then, [tex]-2x+1= -\frac{4}{x}[/tex]

∴ [tex]y = -2x+1[/tex]

Hence, we will plot the graph for the function [tex]y = -2x+1[/tex] on the same graph and the points of intersection gives the solution.

The function is a linear equation

Can you find the area of the figure?

Answers

Answer:

Below

Step-by-step explanation:

First I found the area of the triangle on the right

A = bh/2

A = (9)(4.5) / 2

A = 20.25 ft^2

Next, the area of the rectangle in the middle

A = lw

A = (7.5)(9)

A = 67.5 ft^2

And now the area of the right triangle on the left

A = bh/2

A = (5)(9) / 2

A = 22.5 ft^2

Add em all up : 20.25 + 67.5 + 22.5 = 110.25 ft^2

Find the amount and the compound interest on rupees 5000 for 2 years at 6% per annum, Interest payable yearly. Answer with full steps and formula NO BAD ANSWERS REQUIRED :D

Answers

Answer:

I. Amount = 5618 Rupees

II. Compound interest = 618 Rupees

Step-by-step explanation:

Given the following data;Principal = 5000 RupeesTime = 2 yearsInterest rate = 6%

To find the compound interest;

Mathematically, compound interest is calculated using the formula;

A = P(1 + r)^t

Where;

A is the future value.P is the principal or starting amount.r is annual interest rate.t is the number of years for the compound interest.

Substituting into the formula, we have;

A = 5000(1 + 0.06)^2

A = 5000(1.06)^2

A = 5000 * 1.1236

A = 5618 Rupees

Next, we would determine the compound interest using the formula;

C.I = A - P

C.I = 5618 - 5000

Compound interest (C.I) = 618 Rupees

Answer:

b=3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

b = 3

Step-by-step explanation:

3(9+9b)=69+136

27+27b = 205

27b = 205-27

27b = 178

b = 178/27

*slaps face*

In the comments you said the "136" is "13b" so ok...

3(9+9b)=69+13b

27+27b = 69 + 13b

27+14b = 69

14b = 69-27

18. If the ratio of males to females in each

females still 5 to 4 if the classes were
considered as one large class instead
of two smaller classes?
Ra

Answers

Answer:

Yes, the ratio is still 5:4.

Step-by-step explanation:

If you have a class of 5 males and 4 females, both numbers can be multiplied to get an even bigger class but the same ratio.

For example:

5 x 5 = 25 males

4 x 5 = 20 females

The amount of males to females is 25:20 when simplified (divided by 5) gets you back to your ratio of 5:4. You also can't go under this because the two don't have a way to get simplified without going into decimals. And I don't think decimals are very good with the number of students.
