At a certain restaurant, the hourly wage for a waiter is 20 percent greater than the hourly wage for a dishwasher, and the hourly wage for a dishwasher is half as much as the hourly wage for a cook's assistant. If a cook's assistant earns $13.00 an hour.

Let's break down the problem and use algebra to solve it step by step

1. Let x be the hourly wage for a dishwasher.

2. We know that the hourly wage for a waiter is 20% greater than the hourly wage for a dishwasher, so the hourly wage for a waiter is

x + 0.2x = 1.2x

3. We also know that the hourly wage for a dishwasher is half as much as the hourly wage for a cook's assistant, so

x = 1/2 * $13.00

x = $6.50

Therefore, the hourly wage for a dishwasher is $6.50.

4. We can substitute x = $6.50 into the expression we found for the hourly wage of a waiter

1.2x = 1.2 * $6.50

1.2x = $7.80

Therefore, the hourly wage for a waiter is $7.80.

5. Finally, we can calculate the difference in hourly wage between a cook's assistant and a waiter

Hourly wage difference = hourly wage for cook's assistant - hourly wage for waiter

Hourly wage difference = $13.00 - $7.80

Hourly wage difference = $5.20

Therefore, a waiter earns $5.20 less than a cook's assistant each hour.

In summary, we can use algebra to find that a dishwasher earns $6.50 an hour, a waiter earns $7.80 an hour, and a waiter earns $5.20 less than a cook's assistant each hour.

Inflation refers to the general increase in prices of goods and services in an economy over a period of time.

A rise in meat prices may be an indication of inflation, but it is not necessarily an automatic or definitive sign of inflation.

Inflation can hurt savers and fixed-income earners, such as retirees on a fixed pension, as the purchasing power of their savings and income decreases.

The Consumer Price Index (CPI) is used to measure the rate of inflation by tracking the average price change of a basket of goods and services commonly purchased by households, including food, housing, transportation, and medical care.

The CPI measures the percentage change in prices from a base period and is calculated by dividing the cost of the basket of goods and services in the current period by the cost of the same basket in the base period and multiplying the result by 100.

y = -5/3 x - 13

Step-by-step explanation:

Parallel lines have the same slope.  The slope will be -5/3

y = mx + b

We will substitute -3 for y (-6,-3).

We will substitute -5/3 for m.

We will substitute -6 for x (-6,-3)

-3 = -5/3(-6) + b

-3 = [tex]\frac{30}{3}[/tex] + b

-3 = 10 + b  Subtract 10 from both sides

Option A is the correct answer.

We have,

This table describes the relationship between membership status and attendance of classes.

To determine if there is a relationship, we need to apply the principle of independence.

If the principle of independence holds, then the events "having a membership" and "attending one or more classes" are independent of each other, and similarly, the events "not having a membership" and "attending none of the classes" are independent of each other.

To check for independence, we can calculate the expected values for each cell assuming independence holds, and compare them to the observed values.

The expected value for "Have a membership" and "Attend one or more classes".

= (40/70) x (31/70) x 70

= 17.86

The expected value for "Have a membership" and "Attend none of the classes".

= (40/70) x (39/70) x 70

= 22.14

The expected value for "Do not have a membership" and "Attend one or more classes".

= (30/70) x (31/70) x 70

= 13.14

The expected value for "Do not have a membership" and "Attend none of the classes".

= (30/70) x (39/70) x 70

= 16.86

Comparing these expected values with the observed values, we see that they are reasonably close, indicating that the principle of independence holds.

Therefore,

We can conclude that this table describes the relationship between membership status and attendance of classes under the principle of independence.

Answer:

x = -1/12

Step-by-step explanation:

It is actually a rather simple proof. Before we get to that, it’s important to understand a couple of other things. Let’s consider the following infinite summation:

X = 1 - 1 + 1 - 1 + 1 - 1 ...

Rearranging the above equation a little bit, we get:

X = 1 - (1 - 1 + 1 - 1 + 1 - 1 ...)

If you look at the term inside the brackets, it in fact equals X. So let’s substitute that:

X = 1 - X

2X = 1

X = 1/2

Now let’s consider another sum.

Y = 1 - 2 + 3 - 4 + 5 - ...

Writing it in another way, we get:

Y = 0 + 1 - 2 + 3 - 4 + 5 + ...

Adding the above two equations:

Y + Y = (1 - 2 + 3 - 4 + 5 ...) + (0 + 1 - 2 + 3 - 4 + 5 ...)

Grouping the corresponding terms within the brackets, we get:

2Y = 1 + 0 - 2 + 1 + 3 - 2 - 4 + 3 + 5 - 4 ...

2Y = 1 - (2-1) + (3-2) - (4-3) + ...

2Y = 1 - 1 + 1 - 1 + 1 - 1 ...

But the summation on the right hand side is X. Let’s substitute it:

2Y = X

2Y = 1/2

Y = 1/4

Finally, let’s consider our original question at hand i.e. the sum of all natural numbers:

S = 1 + 2 + 3 + 4 + ...

We defined Y earlier as:

Y = 1 - 2 + 3 - 4 + ...

Subtracting Y from S:

S - Y = 1 - 1 + 2 + 2 + 3 - 3 + 4 + 4 + ...

S - Y = 4 + 8 + 12 + 16 + ...

We just calculated the value of Y to be 1/4. So let’s substitute it:

S - 1/4 = 4 x (1 + 2 + 3 + 4 + ...)

S - 1/4 = 4S

3S = -1/4

S = -1/12

The greatest common factor is 2z^2

How you find it is first you find the greatest common factor of the two numbers, which is 2 (2 is the greatest number that can be multiplied into 2 and 10; 2 times 1 = 2 and also 2 times 5 = 10)

Then you find the greatest common factor of the variables, which is z^2.

(z^2 is the largest that can go into z^3 and z^2 because z^2 times z = z^3 and z^2 = z^2)

After that, you just multiply them together to get 2z^2

Step-by-step explanation:

Correct answer is option A. If the height of the pyramid on the drawing was 3 1/2 inches, then the height of the actual pyramid is 98 feet

When a scale drawing or model is made, the actual object is typically much larger than the drawing or model. In order to represent the object in a smaller size, a ratio is used to scale down the dimensions. This ratio is can be in a fraction form or 'is to' form. We can use this ratio to easily calculate the dimensions of a replica from the actual object or vice versa.

To find the height of the actual pyramid, we need to use both scales given in the problem.

We can start by finding the height of the replica using the first scale:

1 inch on the drawing = 2 feet on the replica

So, 3.5 inches on the drawing = (3.5 * 2) feet on the replica = 7 feet on the replica

Now, using the second scale we can find the height of the actual pyramid:

1 foot on the replica = 14 feet on the actual pyramid

So, 7 feet on the replica = (7 * 14) feet on the actual pyramid = 98 feet

Therefore, the height of the actual pyramid is 98 feet.

In this case, renting the huge van would be a more cost-effective option because it would run you $289 as opposed to $354.65 for the minivan.

To compare the costs of renting the minivan and the large van, we need to calculate the total cost for each option.

For the minivan, the cost per day is $24.95 and the cost per mile is $0.15. So, for 7 days and 1,200 miles, the total cost would be:

Total cost = 7($24.95) + 1,200($0.15)

= $354.65

For the large van, the cost is a flat rate of $289 per week with no additional charge for mileage. So, for 7 days and 1,200 miles, the total cost would be:

Total cost = $289

We can see here that the equation that best models the situation is: B.  13 - (60h/23) = 10.

Speed is a scalar quantity that describes how fast an object is moving, or the rate at which it covers distance. It is typically measured in units of distance per unit of time, such as miles per hour or meters per second.

Speed only tells us how fast an object is moving, without any information about the direction of motion or changes in direction.

We can see that if we find the time, h in hours, we will have:

h = (3 x 23)/60

Simplifying this expression gives us:

h = 69/60

Therefore, the equation is:

h = 1.15

(Note: 3 is gotten from 13 gallons - 10 gallons = 3 gallons that was used at that particular time and speed).

If we substitute h = 1.15 into our model equation, we will get the correct answer.
