Answer:

The x and y intercept are (96,30)

Step-by-step explanation:

8y=240-2.5x

y=240/8-2.5x/8

y=30-0.3125x

The y intercept=30

The x intercept=96 thus 30=0.3125x,x=30/0.3125

Answer:

The number of cartons of concentrated orange juice she needs in 4.5 gallons of orange juice is 12 cartons of orange juice

Step-by-step explanation:

The given parameters are;

The volume of the concentrated orange juice = 12 fluid ounce cartons

The ratio of orange juice concentrate to water = 12 fluid ounces to 36 fluid ounces

The amount of orange juice James need = 4.5 gallons = 576 fluid ounces

Therefore;

The  ratio of orange juice concentrate to water is 12:36

Therefore;

Let 'x' represent the amount of concentrated orange juice in 4.5 gallons of orange juice, and let 'y' represent the amount of water in the 4.5 gallons of orange juice, we have;

x + y = 4.5 (gallons)...(1)

x:y = 12:36 = 1:3

∴ x/y = 1/3

3·x = y...(2)

From equation (1) and equation (2), we have;

x + y = 4.5

x + 3·x = 4.5

x = 4.5/4 = 1.125

x = 1.125

The amount of concentrated orange juice in 4.5 gallons of orange juice, x = 1.125 gallons

∴ y = 3 × x = 3 × 1.125 = 3.375

y = 3.375

The amount of water in the 4.5 gallons of orange juice, y = 3.375

Therefore, we have;

4.5 gallons = 576 fluid ounces

∴ 1.125 gallons = (576/4.5) × 1.125 = 144 fluid ounces

The amount of fluid ounces per carton = 12 fluidounces/carton

∴ The number of cartons in 144 fluid ounces = 144 fluidounces ÷ 12 fluidounces/carton = 12 cartons

The amount of concentrated orange juice she needs in 4.5 gallons of orange juice, x = 1.125 gallons = 144 fluidounces = 12 cartons

The amount of concentrated orange juice she needs in 4.5 gallons of orange juice, x = 12 cartons of orange juice

The amount (number of cartons) of concentrated orange juice she needs in 4.5 gallons of orange juice, x = 12 cartons of orange juice.

Thus, the measure of the value of 'x' for the given length of arc of circle is found as: x = 90.

The products of a measurements of the segments of two chords are equal if they overlap in a circle.

For the given arc length  of circle:

Let the intersection of the both chords be 'O'.

m∠KOL = 180 - x  ...eq 1 (linear pair).

By the  intercept chord theorem:

m∠KOL = (arc JM + arcKL)

Put the value of eq 1.

180 - x = 1/2(30 + 2x - 30)

180 - x = 1/2 * 2x

180 = x + x

x = 180/2 = 90

Thus, the measure of the value of 'x' for the given length of arc of circle is found as: x = 90.

The value of angle x in the diagram of equilateral triangle and square is 120⁰.

If one vertex of the equilateral triangle is in the center of the square, and one vertex of the square is in the center of the equilateral triangle, the value of x is calculated as follows;

Since the vertex of the equilateral triangle is at the center, then angle x will be equal to the opposite angle.

Also, the center angle will be equal to 60⁰, individual angle of equilateral triangle.

( x + x ) + ( 60 + 60 ) = 360 ( sum of angles in a quadrilateral )

2x + 120 = 360

2x = 240

x = 240 / 2

Step-tep explanation:

We are evaluating a project that costs $786,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 65,000 units per year. Price per unit is $48, variable cost per unit is $25, and fixed costs are $725,000 per year. The tax rate is 22 percent, and we require a return of 10 percent on this project

The tax rate for 10% is IRR = 78%.

The Initial evaluating cost is $786000 and the

Depreciation expense per year will be  = $786,000 / 8 = $98,250.

and the contribution margin per unit = $48 - $25 = $23

total units sold  Projected per year = 65,000

fixed costs  will be per year = $725,000

At Present the tax rate = 22%

Net cost fixed per year  = -$786,000

Net Cost Fixed year 1-8 = {[($23 x 65,000) - $98,250 - $725,000] x 0.78} + $98,250 = $622,215

Net Per Variable  = $2,533,471.10

Hence the answer is, The tax rate for 10% is IRR = 78%.

To find the percentage of faculty members who work no more than 53.2 hours a week, we need to calculate the z-score and then use the standard normal distribution table.

First, we calculate the z-score using the formula: z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation. In this case, the z-score is (53.2 - 46) / 2.4 = 3. Next, we look up the cumulative probability in the standard normal distribution table corresponding to a z-score of 3. From the table, we find the cumulative probability to be approximately 0.9987.  To find the percentage, we multiply the cumulative probability by 100: 0.9987 * 100 = 99.87%.

Therefore, no more than 99.87% of faculty members work more than 53.2 hours a week.  Rounded to two decimal places, the answer is 99.87%.

Answer:

New radius(r) = 3.65 (Approx)

Step-by-step explanation:

Given:

Radius of sphere(R) = 8

Find:

New radius(r)

Computation:

Volume of sphere = (4/3)πR³

Volume of sphere = (4/3)π(6)³

Volume of sphere = 288π

Volume of ring = (4/3)π(R²-r²)³/²

Half volume of sphere = Volume of ring

288π / 2 = (4/3)π(R²-r²)³/²

144 = (4/3)(6²-r²)³/²

108 = (6²-r²)³/²

New radius(r) = 3.65 (Approx)

Just took the quiz.

In the given list of numbers (56, 25, 26, 28, 81, 93, 92, 85, 99, 87), when the Partition function is called with the range from 5 to 9, the pivot chosen is 93. The low partition consists of the numbers less than or equal to the pivot.

Quicksort is a sorting algorithm that involves partitioning the list around a pivot and recursively sorting the resulting sublists. In this case, the given list of numbers is (56, 25, 26, 28, 81, 93, 92, 85, 99, 87).

When the Partition function is called with the range from 5 to 9, the pivot is chosen as the element at the midpoint of that range. So, the midpoint of the range from 5 to 9 is (5 + 9) / 2 = 7. Therefore, the pivot chosen is the 7th element of the list, which is 93.

The low partition consists of the numbers less than or equal to the pivot. In this case, the numbers less than or equal to 93 are 56, 25, 26, 28, 81, and 92.

Hence, the pivot is 93, and the low partition consists of the numbers 56, 25, 26, 28, 81, and 92.

Answer: f(x)=-.5x+1x      f(1)=-.5(1)+1= f(1)= 1-.5= .50, so after selling one bag of popcorn they make a $0.50 profit.

Step-by-step explanation: Hope this helps!! :))

Answer: 51 bags.

Step-by-step explanation:

Profit = (price of goods sold) - (cost of goods sold)

Therefore, the profit per bag of popcorn is $1.50 - $0.50 = $1.00.

The fixed cost of the machine is $50.

For every bag sold, we make $1.00 of profit. If we divide the price of the popcorn machine by the profit on each bag of popcorn, we find how many bags we need to sell. $50 / $1.00 = 50 bags. If we sell 50 bags, we break even. The 51st bag and every bag sold after makes a profit, so therefore, in order to make a profit, the student council must sell at least 51 bags of popcorn.

Answer: x + x - 40 = 152; 96

Step-by-step explanation:

If x is the highest score, then x - 40 would be the lowest score because of a 40 point difference. Adding these terms would result to x + x - 40 which is equal to 152. This sets up the equation x + x - 40 = 152. The value of x in this equation would be 96.
