25 points plus brainliest

Answer:

The indifference point is 4 hours.

Step-by-step explanation:

Giving the following information:

Waiter A:

Fixed cost= $20

Unitary variable cost= $5.5 per hour

Waiter B:

Fixed cost= $24

Unitary variable cost= $4.5

First, we structure the total cost formula for each waiter:

Waiter A= 20 + 5.5*x

Waiter B= 24 + 4.5*x

x= number of hours

Now, we equal both formulas and isolate x:

20 + 5.5x = 24 + 4.5x

1x = 4

x= 4

The indifference point is 4 hours.

Prove:

Waiter A= 20 + 5.5*4= $42

Waiter B= 24 + 4.5*4= $42

2 2/5 / 1/5 = 12 or 2.4 / .2 = 12

1/2 * 12 = 6

Answer: 3:1

Step-by-step explanation:

From the question, we are informed that a gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.

We are further told that the bike has 36 teeth on the front sprocket and 12 teeth on the rear sprocket.

Based on the explanation given in the question, the gear ratio for the bike would be the ratio of 36 to 12. This will be:

= 36:12

Since 12 is a common factor. It can be further reduced to 3:1.

Therefore, the gear ratio is 3:1

Maximum Value: ∞

General Formulas and Concepts:

Calculus

Basic Power Rule:

Step-by-step explanation:

Step 1: Define

f(x) = 3x² + x³

Step 2: Find Derivative

Step 3: Analyze

We see that our derivative is the graph of some sort of parabola. The parabola would be opening upwards.

Therefore, the maximum value of the derivative would be ∞, as the parabola's output y infinitely increases.

Answer:

Third choice, likely

Second choice, equally likely

Step-by-step explanation:

There's 14 red ones and 3 green ones, so there's 17 marbles in total. !4 red ones so the probability is 14/17, which is a very high chance so yea

It's not certain because there's still 3 marbles that are not red, so while the chance of it not being red is low, it's not none so u can't choose certain

There's only 2 sides to a coin, so the chance of getting either heads or tails is 1/2. So there's an equal chance

The volume of pyramid R is 144 cubic inches.

We have to find the dimensions of pyramid Q using the given information:

Volume of pyramid Q = 96 cubic inches

The volume of a pyramid is given by the formula:

Volume = (1/3) * base area * height

Since pyramid Q has a rectangular base, let's assume its base has dimensions length (L), width (W), and height (h).

Volume of pyramid Q = (1/3) * (L * W) * h

We are given that the volume of pyramid Q is 96 cubic inches:

96 = (1/3) * (L * W) * h

Now, let's move on to pyramid R:

Base area of pyramid R = (1/2) * base area of pyramid Q

Base area of pyramid R = (1/2) * (L * W)

Height of pyramid R = 3 * height of pyramid Q

Height of pyramid R = 3 * h

Now, we can calculate the volume of pyramid R using the same volume formula:

Volume of pyramid R = (1/3) * (base area of pyramid R) * (height of pyramid R)

Volume of pyramid R = (1/3) * ((1/2) * (L * W)) * (3 * h)

Volume of pyramid R = (1/2) * (L * W) * (h)

We know that the volume of pyramid Q is 96 cubic inches,

so (L * W) * h = 96*3 = 288.

Now, let's substitute this value into the formula for the volume of pyramid R:

Volume of pyramid R = (1/2) * 288

Volume of pyramid R = 144 cubic inches

So, the volume of pyramid R is 144 cubic inches.

The 25th battery replacement will occur in October.

What is Rate of change?

A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.

The last time he changed his batteries was in May, so we know he needs to change them every 5 months. So we can figure out when he has to replace them for the 24th time. The first thing we need to do is figure out how many months have passed since he has to replace them 24 times a year.

[tex]\begin{aligned}5\text{ months}\cdot 24\text{ replacement}&= 120\text{ months}\end{aligned}[/tex]

From the amount of months we can calculate the amount of years that will pass.

120 months x  (12 months/ 1 year ) = 10 year

Adding 10 years to May results in 10 years later May, which is the month of the 24th replacement.

That is the 24th battery replacement will occur in May and therefore, the 25th battery replacement will occur in October.

Answer:

6 m

.006 km  

6,000 mm

Step-by-step explanation:

Let's look at some conversions real quick:

1 cm --> 10 mm (multiply cm by 10)

1 cm --> 0.00001 km (divide cm by 100000)

1cm --> 0.01 m (divide cm by 100)

Now that this is laid out, lets do these conversions for 600 cm.

Meters (m) = 600/100 = 6 meters

Kilometers (km) = 600/100000 = .006km

Millimeters (mm) = 600 * 10 = 6,000 mm

Answer:

If the recipe is cut in half, 3/8 teaspoon of salt is needed.

Step-by-step explanation:

Since the recipe is cut in half, we need to find 1/2 of 3/4. This means we need to multiply 1/2 times 3/4. For the numerator, 1 times 3 equals 3. For the denominator, 2 times 4 equals 8. The fraction is 3/8.

Answer: $310,000

Step-by-step explanation:

In 40 additional years, the amount she made less than her college counterparts was;

= 10,000 * 40

= $400,000

She however made $90,000 more than them as they went to college;

= 400,000 - 90,000

= $310,000

The long-term financial cost was $310,000.

Answer:

1) y=1/2x+4 and y=-2x-4

2) y-9 = -2(x+7)

Step-by-step explanation:

1) Perpendicular lines must have reciprocal slopes. So, the sign must be switched and the numerator and denominator must be switched.

2) Point-slope form is [tex]y-y_{1} = m(x-x_{1})[/tex]

So plug the slope and point in.

y - 9 = -2 (x - (-7))

y-9=-2(x+7)

Step-by-step explanation:

Answer:

First result: X = 248/3 or 82.67    Second result: X = 260/3 or 86.57

Step-by-step explanation:

1st one: 7x + 8(x + 1/4) = 3(6x - 90 - 8)

              7x + 8x + 2 = 18x - 270 - 24

                 15x + 2 - 2 = 18x - 246 - 2

                  15x - 18x = 18x - 18x -248

                -3x = 248  -->   -3x/3 = 248/3

                    X = 248/3 or X = 82.67

2nd one: 7x + 8(x+1/4) = 3(6x - 90) - 8

                  7x + 8x + 2 = 18x - 270 - 8

                   15x + 2 - 2 = 18x - 262 - 2  

                    15x - 18x = 18x -18x - 260

                   -3x = 260 --> -3x/3 = 260/3

                        X = 260/3 or X = 86.67
