Answer:

he has 121 cookies now

Step-by-step explanation:

8 times 14 plus 9

8 times 14 = 112 + 9 = 121

Answer:

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

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.

3 - 15a - 30

-15a - 27

As per linear equation, the value of the given expression is (-27 - 15a).

"A linear expression is an expression in which the highest power of the variable is always 1.

Given expression is:

3 - 5(3a + 6)

= (3 - 15a -30)

= (-27 - 15a)

Therefore, the value of the given expression is (-27 - 15a).

Answer:

(-2, 1)

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:

½÷n+5=11

or

0.5÷n+5=11

Answer:

no

Step-by-step explanation:

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.

Step-by-step explanation:

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.

                                           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,

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:

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

(x, y) → (3x, 3y)

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:

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

(x, y) → (1/2x, 1/2y)

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)
