The ratio of saving money for Lisa and her brother is 5 : 2.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Lisa and her brother are saving money to go on a trip. For every $2 Lisa saves, her brother saves $5.

Therefore, The ratio of saving money for Lisa and her brother is,

Answer:

Population of bacteria in culture after 14 hours is 285541.

Step-by-step explanation:

We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]

Here initial population is 41000 , t=5 and d=14

Plug in these values into the formula

[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]

Simplify

[tex]P_{14}= 41000(2)^{2.8}[/tex]

     =41000(6.9644)

     =285540.5847...

To the nearest whole number is 285541.

Answer:

285541.

Step-by-step explanation:

P0=41000-The initial population

t=14-Time elapsed

d=5-The doubling time

Pt=P0⋅2^t/d

Pt=41000⋅2^14/5-Plug in

Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

Answer:

y - 2 = 2(x + 5)

Step-by-step explanation:

Use the point slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Plug in the point and slope:

y - y1 = m(x - x1)

y - 2 = 2(x + 5) is the equation

Answer:

Sunayana's income is ₹25000 and expenditures are ₹15000.

Step-by-step explanation:

Let i denote the monthly income and e denote the expenditures.

We know that the ratio of the monthly income to expenditure is 5:3. So, we can write the following proportion:  

[tex]\displaystyle \frac{i}{e}=\frac{5}{3}[/tex]

Let's multiply both sides by e. This yields:

[tex]\displaystyle i=\frac{5}{3}e[/tex]

We know that when the income is increased by 5000 and the expenditures are decreased by 3000, the new ratio is 5:2. So, we can write the following proportion:

[tex]\displaystyle \frac{i+5000}{e-3000}=\frac{5}{2}[/tex]

Let's multiply both sides by [tex](e-3000)[/tex]:

[tex]\displaystyle i+5000=\frac{5}{2}(e-3000)[/tex]

Since we know that [tex]i=\frac{5}{3}e[/tex], substitute:

[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}(e-3000)[/tex]

So, let's solve for the expenditures. Distribute the right:

[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}e-7500[/tex]

Subtract [tex]\frac{5}{2}e[/tex] from both sides:

[tex]\displaystyle -\frac{5}{6}e+5000=-7500[/tex]

Subtract 5000 from both sides:

[tex]\displaystyle -\frac{5}{6}e=-12500[/tex]

Multiply both sides by -6/5. So, the expenditures are:

[tex]e=\text{Rs }15000[/tex]

We can use the original ratio to find Sunayana's income:

[tex]\displaystyle i=\frac{5}{3}e[/tex]

Substitute 15000 for e. Evaluate:

[tex]\displaystyle i=\frac{5}{3}(15000)=\text{Rs }25000[/tex]

So, Sunayana's income is ₹25000 and expenditures are ₹15000.

And we're done!

Answer: Income = 25000, Expenditures = 15000

Step-by-step explanation:

A ratio of 5:3 can also be written in fraction form as [tex]\dfrac{5}{3}[/tex] (which is in simplified format from [tex]\dfrac{5x}{3x}[/tex]).

Adding 5000 to 5x results in 5x + 5000

Subtracting 3000 from 3x results in 3x - 3000

--> [tex]\dfrac{5x+5000}{3x-3000}[/tex]

The new ratio of 5:2 can be written in simplified fraction form of [tex]\dfrac{5}{2}[/tex].

Set the fractions equal to each. Then cross multiply and solve for x.

   [tex]\dfrac{5x+5000}{3x-3000}=\dfrac{5}{2}[/tex]

5(3x - 3000) = 2(5x + 5000)             Cross multiplied

15x - 15000 = 10x + 10000                Distributed

5x - 15000 =            10000                Subtracted 0x from both sides

5x               =            25000               Added 15000 to both sides

               x = 5000                            Divided 5 from both sides

The original ratio of 5 : 3     -->  5x:3x

where 5x is the income and 3x is the expenditures results in:

income = 5x                            expenditures = 3x

             = 5(5000)                                         = 3(5000)

             = 25000                                          = 15000

Answer:

RS = 8

Step-by-step explanation:

Given that R is on QS , then

QR + RS = QS , substitute values

3x - 8 + 2x = 3x , that is

5x - 8 = 3x ( subtract 3x from both sides )

2x - 8 = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

RS = 2x = 2 × 4 = 8

Step-by-step explanation:

So we know that Jordan bought 12 balls and Annika bought 16. We also know that they came is packages that each contain some number of balls. We are trying to find the greatest possible number of tennis balls in each package.

The greatest possible number of tennis balls in each package would be the greatest common factor of 12 and 16.

To find the greatest common factor of 12 and 16, lets first find all of the factors of 12 and the factors of 16.

12: 1, 2, 3, 4, 6, 12

16: 1, 2, 4, 8, 16

From looking at the factors of 12 and 16, we can find that the greatest common factor of 12 and 16 is 4. Therefore, the greatest possible number of tennis balls in each package would be 4.

Answer:

I think that's 18

Step-by-step explanation:

Given parameters:

Cost of paint per month = $320

Cost of quality plain shirts  = $9 each

Selling price  = $24

Rent per month  = $100

Unknown:

Number of shirts Sam has to sell to break even  = ?

Solution :

 Let the number of shirt sold each month  = y

To break even the cost price per shirt must be equal to the selling price;

   i.e;

      Cost price  = selling price at break even point;

Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent

                  = 320 + 9y + 100

                  = 420 + 9y

Selling price =  24y

To break even;

                      420 + 9y  = 24y

                      420  = j24y - 9y

                      420 = 15y

                          y  = [tex]\frac{420}{15}[/tex]  = 28

To break even, Sam must sell 28 shirts in a month.
