Sara sold hotdogs and drinks at the soccer game.
18 hot dogs and 9 drinks sold for $45.00
20 hot dogs and 12 drinks sold for $52.00
What is the charge for an order of 4 hot dogs and 3 drinks?

Answers

Answer:

$11

Step-by-step explanation:

Set up the system of equations

18x + 9y = 45

20x + 12y = 52

Let's try to get y on one side for the first equation.

9y=45-18x

y=5-2x

Now substitute it into the second equation.

20x + 12(5-2x) = 52

20x + 60 - 24x = 52

-4x = -8

x = 2

Now solve for y using the first equation.

18(2) + 9y = 45

36 + 9y = 45

9y = 9

y = 1

Now that we know x and y we can solve for the price of 4 hot dogs and 3 drinks.

4(2) + 3(1) = z

8 + 3 = z

11 = z

That means that the price is 11 dollars.

Can someone help me with this? During a certain period of time about 2000 penguins had an annual growth rate of 19% why will the population of penguins be after 5 years? This is exponential growth and decay

Answers

Answer:

Future amount of penguin = 4,772.70

Step-by-step explanation:

Given:

Current amount of penguin = 2,000

Growth rate r = 19% = 0.19

Number of year n = 5

Find:

Future amount of penguin

Computation:

Future amount of penguin = Current amount of penguin[1+r]ⁿ

Future amount of penguin = 2000[1+0.19]⁵

Future amount of penguin = 4,772.70

Given the preimage points: find the coordinates
of the dilated image using the scale factors. *look at picture*

Answers

                                           Question 1)

Answer:

Please see the explanation.

Step-by-step explanation:

We know that the dilation of an original object shows how much bigger or smaller the image will really get, as compared to the original shape.

Also,

if the value of scale factor > 1, the image will get bigger.if the value of scale factor < 1, the image will get smaller.

The new coordinates of the image can be determined by multiplying the scale factor with the coordinates of the original object.

Given the preimage points:

A(0, 5)B(4, 9)C(-1, -8)

The formula of the dilation by a scale factor of 3:

(x, y) → (3x, 3y)

As the scale factor > 1, so the image will be bigger.

Therefore, the coordinates of the dilated image after the dilation by a scale factor of 3 will be:

A(x, y) → (3x, 3y) = A(0, 5) → (3(0), 3(5)) = A'(0, 15)

B(x, y) → (3x, 3y) = B(4, 9) → (3(4), 3(9)) = B'(12, 27)

C(x, y) → (3x, 3y) = C(-1, -8) → (3(-1), 3(-8)) = C'(-3, -24)

                                               Question 2)

Answer:

Please see the explanation.

Step-by-step explanation:

Given the preimage points:

A(0, 5)B(4, 9)C(-1, -8)

The formula of the dilation by a scale factor of 1/2:

(x, y) → (1/2x, 1/2y)

As the scale factor < 1, so the image will be smaller.

Therefore, the coordinates of the dilated image after the dilation by a scale factor of 1/2 will be:

A(x, y) → (3x, 3y) = A(0, 5) → (1/2(0), 1/2(5)) = A'(0, 5/2)

B(x, y) → (3x, 3y) = B(4, 9) → (1/2(4), 1/2(9)) = B'(2, 9/2)

C(x, y) → (3x, 3y) = C(-1, -8) → (1/2(-1), 1/2(-8)) = C'(-1/2, -4)

Step-by-step explanation:

Well, to actually graph it, for the first line you'd have one point at (0, -1) [0 right, 1 down] , then you go down one, right one, and place a point there, down another, right another, and repeat.

For the second you'd place a point on (0, 3) [0 right, 3 up] and then go one up, one right, and place a point. One up, one right and place a point and repeat that. the point where the two lines cross would be your answer. If you don't want to do that then the answer is (-2, 1) I believe.

(ANSWER FOR FREE BRAINPOINTS!) (FIRST TO ANSWER GETS BAINLIEST) The local park has a rectangular swimming pool that measures 40 yards in length and 15 yards in width. The community is planning to build a smaller swimming pool that is similar to the current pool. 40 yards, 15 yards, 24 yards. If the length of the new smaller pool will be 24 yards, what will be the width of the smaller pool in yards?

Answers

Answer:

9 yards

Step-by-step explanation:

Since both pools are similar, therefore the ratio of their length and width would be equal. That is:

Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool

Thus, we can set up a proportion as shown below:

Let the width of the new swimming pool be x.

40 : 24 = 15 : x

[tex] \frac{40}{24} = \frac{15}{x} [/tex]

Cross multiply

[tex] 40*x = 15*24 [/tex]

[tex] 40x = 360 [/tex]

Divide both sides by 40

[tex] x = \frac{360}{40} [/tex]

[tex] x = 9 [/tex]

The width of the new swimming that is smaller would be 9 yards.

Step-by-step explanation:

the sum of four times a number and another number is 10. The difference of the two numbers is 35. What is the larger number? Also please explain how you got that answer

Answers

Answer:

The two numbers are 9 and -26.

The larger number is 9.

Step-by-step explanation:

Let the two unknown numbers be x and y.

The sum of a four times a number x and another number y is 10. Hence:

[tex]4x+y=10[/tex]

And the difference between the two numbers is 35. So:

[tex]x-y=35[/tex]

So, we have the system of equations:

[tex]\left\{ \begin{array} \ 4x+y=10 \\ x-y=35 \end{array}[/tex]

From the second equation, we can add y to both sides:

[tex]x=y+35[/tex]

Now, we can substitute this into the first equation:

[tex]4(y+35)+y=10[/tex]

Distribute:

[tex]4y+140+y=10[/tex]

Simplify:

[tex]5y+140=10[/tex]

Subtract 140 from both sides:

[tex]5y=-130[/tex]

Divide both sides by 5:

[tex]y=-26[/tex]

So, the value of y is -26 .

Then it follows that the value of x is:

[tex]x=y+35[/tex]

Substitute -26 for y:

[tex]x=-26+35=9[/tex]

So, our two numbers are 9 and -26.

The larger number is 9.

So, our answer is 9.

You can also use sites ending in .edu. Theyre generally trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the sources author before proceeding. Some .org and .com sites are credible, but its important to verify their authenticity. When reviewing a source, ask these questions:Who is the author?Is this person a cancer expert?What is the documents purpose?Does the document state facts that scientists can prove with evidence?Are there opinions in the document?How old is the document?Do other credible sources support the statements in the document?Search for credible websites and note the information they contain.
