A potato chips manufacturing facility uses 1/6 of a barrel of oil in each batch. The facility used 2/3 of a barrel of oil yesterday. How many batches of potato chips did the facility make? A. 2/3 B. 1/4 C.2 D.4

Answers

Answer 1
The answer is D. 2/3 = 4/6 4/6 divided by 1/6 = 4
Answer 2

Answer:

Option D. 4 batches

Step-by-step explanation:

A potato chips manufacturing facility uses 1/6 barrel of oil in each batch and we have to find the batches of potato chips manufactured in 2/3 of a barrel.

We will use unitary method to solve this question.

∵ [tex]\frac{1}{6}[/tex] barrel is required to manufacture batch = 1

∴ 1 barrel is required to manufacture batches = 1 ÷ [tex]\frac{1}{6}[/tex]

∴ [tex]\frac{2}{3}[/tex] barrel is required to manufacture batches = [tex](\frac{1}{\frac{1}{6}})(\frac{2}{3})=(\frac{6}{1})(\frac{2}{3})=6.\frac{2}{3}=4[/tex]

Therefore Option D.4 is the correct option.

This problem exercises the concept of "similar triangles."

With similar triangles, we can compare the sides using ratios.
The equation we can use to find side A is stated below.

Side 1A / Side 1B = Side 2A / Side 2B

The number refers to the triangle, and the letter refers to the side of each triangle. Side A in both triangles must be the base of the triangle, and side B in both triangles can be either of the other sides. The only restriction is that once we pick a side B on triangle 1, we must pick that same side on triangle 2.

Given that P = (2, 9) and Q = (4, 14), find the component form and magnitude of vector PQ.

Answers

the magnitude of the vector is
[tex] \sqrt{2 {}^{2} + 5 {}^{2} } = \sqrt{29} [/tex]
the component form is
<2,5>
To find the component form, <x2-x1, y2-y1>
We have P(2,9) meaning, x1=2, y1=9
And, Q(4,14) meaning, x2=4, y2=14
Now PQ = <4-2, 14-9> = <2, 5>

Now to find the magnitude, we use the distance formula aka the Pythagorean Theorem. a^2 + b^2 = c^2 and we have, x=2, y=5
So, 2^2 + 5^2 = c^2 =29
Therefore, the magnitude is c = sqrt of 29.

How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number. The large tire has a diameter of 60 inches. The small tire has a radius of 9 inches.

Answers

Final answer:

For the large tire with a diameter of 60 inches, it would make 38 rotations after traveling 600 feet. The small tire with a radius of 9 inches would make 127 rotations in the same distance.

Explanation:

First, let's convert the feet into inches since the tire measurements are given in inches. There are 12 inches in a foot, so 600 feet is equal to 7200 inches. Now, we need to determine the circumference of each tire, which we can find using the formula for the circumference of a circle which is 2πr (twice the product of pi and the radius).

For the large tire, the diameter is 60 inches, so the radius (r) is half the diameter, which is 30 inches. Thus, the circumference of the large tire would be 2π*30, which is about 188.5 inches. The large tire would therefore make about 7200/188.5 = 38 rotations.

The small tire has a radius (r) of 9 inches, so its circumference is 2π*9, which is about 56.55 inches. The small tire would hence make about 7200/56.55 = 127 rotations.

Please note that the numbers are rounded off to the nearest whole number as requested.

Final answer:

The large tire makes approximately 38 rotations, and the small tire makes approximately 128 rotations when each travels a distance of 600 feet.

Explanation:

To find the number of rotations a tire makes, you first need to know the circumference of the tire, which represents the distance the tire would cover in one full rotation. The circumference of a circle (or tire, in this case) is calculated as 2πr, where r is the radius of the circle.

For the large tire with a diameter of 60 inches (which makes the radius 30 inches because the radius is half the diameter): The circumference is 2π × 30 = 188.5 inches. Convert this to feet because the distance given is in feet. So, 188.5 inches is about 15.7 feet. Divide the total distance by the circumference to find the number of rotations: 600 feet / 15.7 feet = approximately 38 rotations.

For the small tire with a radius of 9 inches: The circumference is 2π × 9 = 56.5 inches, which is about 4.7 feet. Divide the total distance by the circumference to find the number of rotations: 600 feet / 4.7 feet = approximately 128 rotations.

A light bulb consumers 1800 watt-hours per day. How long does it take to consume 9450 watt-hours?

Answers

Final answer:

To find out how long it takes for a light bulb to consume 9450 watt-hours, when it uses 1800 watt-hours per day, divide 9450 watt-hours by 1800 watt-hours per day, which equals 5.25 days.

Explanation:

The question involves calculating how long it takes for a light bulb to consume a certain amount of energy (9450 watt-hours) given its daily consumption rate (1800 watt-hours per day).

To find the duration, you simply divide the total energy by the daily consumption rate:

Total energy to be consumed = 9450 watt-hours

Daily energy consumption = 1800 watt-hours per day

Duration = Total energy ÷ Daily energy consumption

Duration = 9450 watt-hours ÷ 1800 watt-hours/day = 5.25 days

Therefore, it will take 5.25 days for the light bulb to consume 9450 watt-hours of energy.

Johnson Certified bought a fiber optic cable for $975,000. The estimated life of the cable is 20 years, after which its salvage value is estimated to be $5,000. Using the straight-line method, what is the annual depreciation to the nearest cent?

Answers

Remember that straight line depreciation can be calculated using the formula:

Gavin's mean score on 3 math tests is 87. What equation can be solved to find x, the score he needs on his next test to bring his mean score up to 90?

Answers

Final answer:

To find the score Gavin needs on his next test to have an average of 90, we understand that the sum of his first three tests and the fourth test, divided by four, must equal 90. Translating this understanding to an equation gives: (261 + x4) / 4 = 90, which can be solved for x4.

Explanation:

The subject posed deals with the understanding of mean averages and algebra. The mean, or average, is calculated by adding up all the values and dividing by the total number of values. In Gavin's case, his mean score of 87 over three tests can be represented algebraically as (x1 + x2 + x3) / 3 = 87. The challenge is to find out what Gavin needs to score in his next test (let's call this x4) to have a new mean score of 90.

To set up the equation we need to understand that now the average is calculated over four tests, and it must equal 90. Thus, the equation to solve is ((x1 + x2 + x3) + x4) / 4 = 90. As we know that the sum of his first three test scores is 87 * 3 (because (x1 + x2 + x3) / 3 = 87), we substitute that sum (261) into the equation:

(261 + x4) / 4 = 90. Solving this equation for x4 will give the score Gavin needs on his next test to achieve an average of 90.

an automobile radiator contains 20 L of antifreeze and water. this mixture is 20% antifreeze. how much of this mixture should be drained and replaced with pure antifreeze so that the mixture will be 50% antifreeze.

Answers

Try this solution (this suggested way is not short, but pure):
1. to make up the scheme of changes; 2. to make up the system of the equations according to the scheme.

Note, that antifreeze is marked by black in the picture.

Final answer:

To make a 20L mixture 50% antifreeze, 7.5L of the mixture should be drained and replaced with pure antifreeze. This calculation is based on the original 20% antifreeze concentration and the goal of reaching a 50% concentration without changing the total volume.

Explanation:

The question asks how much of a 20L mixture, which is 20% antifreeze, needs to be drained and replaced with pure antifreeze so the mixture will be 50% antifreeze. To solve this, first calculate the current amount of antifreeze in the mixture: 20L * 20% = 4L. Let's say x liters are drained and replaced with pure antifreeze. The volume of the solution does not change, the remaining 20L. After replacement, the quantity of antifreeze is (4 - 0.2x + x) liters (since we subtract the antifreeze drained, which is 20% of x, and add back x liters of pure antifreeze), and we require this to be 50% of the total, which is 10L (50% of 20L).

Setting up the equation: 4 - 0.2x + x = 10. Simplifying gives 0.8x = 6, so x = 7.5. Therefore, 7.5L of the mixture should be drained and replaced with pure antifreeze to achieve a 50% concentration.

You apparently need to find the greatest common divisor of (418, 456, 494). You can start by looking at the differences between these numbers. They are
.. 456 -418 = 38
.. 494 -456 = 38
So, if 38 divides these numbers evenly, that is the number of seats in each car. (It does).

train 1 had 418/38 = 11 cars
train 2 had 456/38 = 12 cars
train 3 had 494/38 = 13 cars

_____
The number of seats in each car could be a sub-multiple of 38, say 19. In that case, the number of cars in each train would be twice the number shown above. It is slightly unusual for a train car to have an odd number of seats, but is not unheard of.
