Answer:

radius = 72.00 units

Step-by-step explanation:

The general formula for circumference (C) of a circle is C = πd, where d is the diameter.  The formula using 3.14 for π is C = 3.14d   The diameter (d) is simply twice the radius (r) as d = 2r

Thus, we can rewrite the formula for circumference in terms of radius as C = 3.14(2r)

To solve for r, we can divide the circumference we're given by the product of 3.14 and 2 to find r:

[tex]C/(2*3.14)=r\\452.16(2*3.14)=r\\452.16/6.28=r\\72=r[/tex]

The answer is option A. That is, the time taken in hours if the train traveled 13 miles in 30 minutes is 4.5 hours.

The relation between distance traveled and time is given by the formula:

Distance = Speed x Time

where distance is the total distance traveled, speed is the rate at which the distance is covered, and time is the duration for which the distance is covered. This formula applies to any type of motion, whether it is linear or circular, and it is often used to calculate the distance covered by an object given its speed and the time it traveled. Alternatively, the formula can also be used to calculate the time required to travel a certain distance given the speed at which the object is traveling.

Given that the total distance = 117 miles. We need to find the time taken in hours if the train traveled 13 miles in 30 minutes.

For that we can use the equation, distance = rate x time

Now, rate = distance/time

Distance = 13 miles, time = 30 minutes = 30/60 hours = 0.5 hours

Therefore, rate = 13 miles / 0.5 hours = 26 miles per hour

Now to find the time it took to travel the entire 117 miles:

time = distance/rate

time = 117 miles/ 26 miles per hour

time = 4.5 hours

Therefore, the answer is (A) 4.5 hours.

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 time it took Milan longer to clean the bathroom is 3 1/8 hours

Time taken for Milan to clean the bathroom = 3 1/4 hours

Time taken for Milan to clean the kitchen = 1/8 hours

Time taken longer for Milan to clean the bathroom = 3 1/4 hours - 1/8 hours

= 13/4 - 1/8

= (26-1) / 8

= 3 1/8 hours

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.

Thus, 13 - (60 × 1.15)/23 = 10.

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.

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.

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.

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.
