Answer:

Hi how are you doing today Jasmine

Answer:

10 years

Step-by-step explanation:

We are told that One year after you buy a tree, it is 10 feet tall. Thus, it's initial height after 1 year is 10 ft.

Now we are told that each year after you buy the tree, it grows 2 feet. This means that it's height after you bought it was; f(0) = 10 - 2 = 8ft

Thus,

f(1) = 8 + 2 = 10

f(2) = 8 + 2 + 2 = 12

f(3) = 8 + 2 + 2 + 2 = 14

The pattern here is;

f(x) = 8 + 2x

Where x is number of years

Thus, for it to reach a maximum height of 28 ft;

28 = 8 + 2x

Subtract 8 from both sides to give;

28 - 8 = 2x

2x = 20

x = 20/2

x = 10 years

Answer:

7 1/2 dozen of cookies

Step-by-step explanation:

If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;

3 dozens cookies = 8 cups of butter

x cups of cookies = 20 cups of butter

Cross multiply

8*x = 3 * 20

8x = 60

x = 60/8

x = 7 4/8

x = 7 1/2

Hence you will need 7 1/2 dozen of cookies

Multiply the numerator together and the denominators together.

1 x 5 / 6 . 7 = 5/42

42 is not a multiple of 5 so the answer is already in the lowest term.

The answer is 5/42

Answer:

b because the Orgin always start with 2 0s

Answer:

A.

Step-by-step explanation:

1. Write down the coordinates of the two points on the line.

(-4,-3) (-1,2)

2. Use the slope formula to find the slope.

Slope formula: y2-y1/x2-x1

2--3/-1--4

Slope: 5/3

Answer:

C) On average, children grow about 9 inches every 2 years.

Step-by-step explanation:

Think about what the slope 9/2 means:

Slope is Change in Y / Change in X which is Change in Height / Change in Age, so 9 inches / 2 years means that on average, children grow about 9 inches every 2 years.

Answer:

[tex]J' =(1, 3)[/tex]

[tex]K' = (4,4)[/tex]

[tex]L' = (6,0)[/tex]

[tex]M' = (-1,-3)[/tex]

Step-by-step explanation:

Given

[tex]J = (-6,6)[/tex]

[tex]K = (-3,7)[/tex]

[tex]L= (-1,3)[/tex]

[tex]M = (-8,0)[/tex]

Transformation: [tex](x,y) = (x+7,y-3)[/tex]

This means that, we add 7 to the x coordinate and subtract 3 from the y coordinate.

For J, we have:

[tex]J = (-6,6)[/tex]

[tex]J' =(-6 + 7, 6 - 3)[/tex]

[tex]J' =(1, 3)[/tex]

For K, we have:

[tex]K = (-3,7)[/tex]

[tex]K' = (-3+7,7-3)[/tex]

[tex]K' = (4,4)[/tex]

For L, we have:

[tex]L= (-1,3)[/tex]

[tex]L' = (-1 + 7,3-3)[/tex]

[tex]L' = (6,0)[/tex]

For M, we have:

[tex]M = (-8,0)[/tex]

[tex]M' = (-8+7,0-3)[/tex]

[tex]M' = (-1,-3)[/tex]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

Step-by-step explanation:

1. First calculate for the gradient m

2. Calculate for the constant C by using any point (0,3) or (3,9)

3. Lastly, put the values found in the equation y = mx + c

1. m = Y2-Y1/X2-X1

=9-3/3-0=2

2. input one point together with m into the equation y=mx+c

3=2(0)+C

C=3

3. Therefore equation of linear relationship is

y = 2x + 3

Answer:

to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled

to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour

Step-by-step explanation:

Answer:

Step-by-step explanation:

LV to Colorado Springs = 595 miles

Colorado Springs to Mil=  929 miles

Total distance =                1524  miles

Average Speed = 1524 miles / 3 hours

Average Speed =  508  miles / hour

Answer:

x = 4

Step-by-step explanation:

Given

6x - 5y = 14 ← substitute y = 2 into the equation

6x - 5(2) = 14

6x - 10 = 14 ( add 10 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

Answer:

[tex]\huge\boxed{\sf x = 4}[/tex]

Step-by-step explanation:

[tex]\sf 6x-5y = 14\\\\Put \ y = 2\\\\6x - 5(2) = 14\\\\6x - 10 = 14\\\\ Adding \ 10 \ to \ both \ sides\\\\6x = 14+10\\\\6x = 24\\\\Dividing \ both \ sides \ by \ 6\\\\x = 24 / 6\\\\x = 4\\\\\rule[225]{225}{2}[/tex]

Answer:

La distancia real entre el hotel y el parque es 960 metros.

Step-by-step explanation:

Este es un caso de factor de escala, donde 5 centímetros en el mapa equivalen a 600 metros a escala real. Por tanto, la distancia entre el parque y el hotel en el mapa halla su equivalente mediante la siguiente regla de tres simple:

[tex]x = \frac{600\,m}{5\,cm}\times 8\,cm[/tex]

[tex]x = 960\,m[/tex]

La distancia real entre el hotel y el parque es 960 metros.

Step-by-step explanation:

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles

Charges for one mile by Prestige car rentals = $0.07

Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]

Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]

Charges for one mile by Gateway Auto = $0.12

Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]

Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]

As per question statement, the charges are same:

[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Answer:

I'm sorry I don't know what that means so I just put the meaing for quadratic formula

Step-by-step explanation:

In elementary algebra, the quadratic formula is a formula that provides the solution to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring, completing the square, graphing and others

I'm sry that this is not the answer you were probaly looking for but all you said was "Solve in quadratic formula" and theres nothing else so pls if you need to fix that pls do so you can get your answer- Lily~Senpai :P

Answer:

24 minutes

Step-by-step explanation:

Given

Ashley = 12 minutes

Becky = 8 minutes

Required

Determine when they will be at the same point again

To do this, we simply determine the least common factor of both.

Ashley = 12, 24, 36, 48....

Becky = 8, 16, 24, 32........

From above, the least common factor is 24

Hence, both of them will be at the starting point in 24 minutes
