Answer:$9.3 is the bars and the rest is the apples

Step-by-step explanation:because you take away from the bars than what is left is the apples.

The difference in price between a cliff bar and an apple is $0.50.

To determine the difference in price between a cliff bar and an apple, we must create two equations based on the information provided:

8C + 4A = 12.40 (equation 1 for the Kendall family)

15C + 9A = 24.30 (equation 2 for the Smith family)

We can solve these equations using substitution or elimination. Let's use the elimination method:

Multiply equation 1 by 2 to get 16C + 8A = 24.80 (equation 3).

Subtract equation 3 from equation 2: (15C + 9A) - (16C + 8A) = 24.30 - 24.80 which gives us -C + A = -0.50.

From this simplified equation, we gather that the price difference between a cliff bar and an apple is $0.50.

Therefore, the difference in price between a cliff bar and an apple is $0.50.

Answer:

3.6

Step-by-step explanation:

Here is the explicit formula for the arithmetic sequence: an = 500 + 50(n - 1)

where:

an is the amount of money Elian receives in week n

500 is the first payment

50 is the common difference

n is the week number (1-indexed)

For example, in week 2, Elian will receive $550 because 500+50(2−1)=550.

The formula is in simplified form because the common difference is a simple integer

Answer:

$62.50

Step-by-step explanation:

The original price is x

It is marked up 40 percent

x+.40x = new price

1.40x = new price

The new price is 87.50

1.40x = 87.50

Divide each side by 1.40

1.40x/1.40 = 87.50/1.40

x =62.50

The price before mark up is 62.50

Answer:

$62.50

Step-by-step explanation:

After mark up, price is

100 + 40 = 140% of cost

140/100 × Cost = 87.50

Cost = 87.50 × 100/140

Cost = $62.50

Answer:

Cholula

Step-by-step explanation:

first find the vlumes of the different pyramids:

FORMULA:

volume = (1/3) * basearea

Cholula- 157,583,664

Cheops- 91,204,000

Answer:

The Cholula Pyramid has a greater volume.

Step-by-step explanation:

volume = (1/3) * area of base * height

In both cases, the base is a square, so the area of the base is (side)^2

volume = (1/3) * (side)^2 * height

Cholula Pyramid:

volume = (1/3) * (side)^2 * height

volume = (1/3) * (1476 ft)^2 * 217 ft

volume = 157,583,664 ft^3

Cheops Pyramid:

volume = (1/3) * (side)^2 * height

volume = (1/3) * (755 ft)^2 * 480 ft

volume = 91,204,000 ft^3

The Cholula Pyramid has a greater volume.

Equation is y=kx.  We have four chance to figure out k; hopefully they all give the same result

x=9, y=63,  y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check  2×7=14, 11×7=77

Answer: k=7,   y=7x

Answer:

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Step-by-step explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Answer:

192 ft

Step-by-step explanation:

The volume of the prism with the given dimension of 2 feet, 8 feet, and 12 feet is 192 cubic feet.

The volume of a prism is the product of the base area and the height of the prism.

The given dimension of the prism is 2 feet, 8 feet, and 12 feet.

Therefore, the volume of the prism is

= (2 × 8 × 12) cubic feet

= 192 cubic feet.

Therefore, the volume is 192 cubic feet.

Final answer:

To calculate the volume of the orange juice can, the formula V = πr²h is used. By finding the radius from the given area of the base and then using the height of the can, the volume is calculated as 3120 cm³, which corresponds to answer choice A.

Explanation:

The student has asked a question about calculating the volume of a cylindrical can of orange juice. Given the area of the circular base is 156 square centimeters and the height of the can is 20 centimeters, the volume can be found by using the formula V = πr²h, where V stands for volume, r is the radius of the base, and h is the height of the cylinder. First, we need to find the radius (r) of the base from the given area, and then substitute it into the volume formula along with the height (h).

To find the radius, we use the formula for the area of a circle, A = πr², where A = 156 cm². Solving for r, we have r = √(A/π). Plugging the area into this formula, the radius (r) is:

r = √(156/π) cm

Then we substitute the radius and height into the volume formula:

V = πr²h

V = π(√(156/π))^2 × 20 cm

V = 156 × 20 cm³

V = 3120 cm³

Therefore, the correct answer is A. 3120 cubic centimeters.

Answer:

Time in weeks you mean not seconds.

His beard should be graphed at point xy 1, 8 and continue at a gradient rate 8 rise / 1 rise showing m = 8/1 . to show one week to be able to meet up with .

Step-by-step explanation:

There are 604800 seconds in a week so first multiply by 5.5 weeks to find the first green dot. 604800 x 5.5 = 3326400 so we know the .5 option shows a rounded next week number.

We can either work downwards to zero or start at 1,8 ever way they will be even balance as 8/32 = 4 8/36 = 4.4 growth and this for example would show a rounded amount, so that 8/8 would be 8 and show the first week, or can be skipped out and start with y = 2x + 10 and then when referring to show .5 growth it would still be a whole number within the equation representing 12 and still be a whole number representing 2 weeks.

The graph does not speak of seconds but weeks, but if you want to use the above and try for 604800 seconds as shown for 1 week, you will have a tough time graphing. Stick to 2,4,6 8, 10, 12, 14, 16, 18 weeks multiplied by 12 = y = 1 + 8 = 0  

y = 2x +8 +2 = 1

y = 3x + 8 +2 = 2

Answer:

y = 4x - 1/2

Step-by-step explanation:

2y = 8x - 1

y = (8x - 1)/2

y = 4x - 1/2

Given:

The graph of the parabola with vertex (-2,-4)

We need to determine the equation of the parabola in vertex form.

Equation in vertex form:

The general form of the equation of the parabola in vertex form is given by

[tex]y=a(x-h)^2+k[/tex]

where a is the constant and (h,k) is the vertex.

Substituting the vertex (-2,-4) in the above formula, we get;

[tex]y=a(x+2)^2-4[/tex]  -------- (1)

To determine the value of a, let us substitute the point that the parabola passes through.

Hence, substituting the point (0,8) in equation (1), we get;

[tex]8=a(0+2)^2-4[/tex]

[tex]8=a(2)^2-4[/tex]

[tex]8=4a-4[/tex]

[tex]12=4a[/tex]

[tex]3=a[/tex]

Thus, the value of a is 3.

Substituting the value a = 3 in equation (1), we get;

[tex]y=3(x+2)^2-4[/tex]

Thus, the equation of the parabola in vertex form is [tex]y=3(x+2)^2-4[/tex]

Answer:

Your answer is gonna be the letter B

Step-by-step explanation:

You're 42. 42-21=21 and 21x2=42.

The current age of your is 42 years old.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.

In other words, an equation is a set of variables that are constrained through a situation or case.

To form an equation we must know the constraint of that condition,

For example x < 5 is a constraint.

Another example of a constraint is;

7x + 3y = 8 like that

Let say

Your age is  = x

21 year ago your age were = x - 21

Now it was half the age x so,

x - 21 = (1/2)x

2x - 42 = x

x = 42

So your current age will be 42 years old.
