Answer:

[tex]\frac{5}{33}[/tex]

Step-by-step explanation:

1.

2

1 5 is what's repeating, and there are two digits.

2.

10² = 100

I chose 10 to the power of 2 because there are 2 digits repeating.

3.

n × 10² = 0.1515 x 10² (square 10)

100n = 0.1515 × 100 (combine like terms)

100n = 15.15

4.

   100n = 15.1515....

-         n = 0.1515....

-------------------------

99n = 15

5.

99n = 15 (divide both sides by 99)

n = [tex]\frac{15}{99}[/tex]

As it asks for simplified form:

[tex]\frac{15}{99}[/tex] ÷ [tex]\frac{3}{3} = \frac{5}{33}[/tex]

Therefore, the fractional equivalent of the repeating decimal n = 0.1515... is [tex]\frac{5}{33}[/tex].

The exponential function that best matches the graph is given as follows:

E. y = 4^(x + 1).

An exponential function, with horizontal asymptote at y = 0, is defined as follows:

y = ab^x.

In which:

From the graph, when x = 0, y = 4, hence the parameter a is given as follows:

a = 4.

When x = -1, y = 1, meaning that when x increases by one, y is multiplied by 4, hence the parameter b is given as follows:

b = 4.

Hence the function is defined as follows:

y = 4(4)^x

y = 4^(x + 1).

Answer:

C revenue

Step-by-step explanation:

Answer:

The movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.

Step-by-step explanation:

Let's use the following variables to represent the number of large and small bags of popcorn sold:

L: the number of large bags of popcorn sold

S: the number of small bags of popcorn sold

We can then write a system of equations based on the information given in the problem:

L + S = 289 (the total number of bags sold is 289)

4L + S = 544 (the total revenue from popcorn sales is $544)

To solve for L and S, we can use the method of substitution. Rearrange the first equation to solve for one variable in terms of the other:

L = 289 - S

Substitute this expression for L in the second equation and solve for S:

4(289 - S) + S = 544

1156 - 4S + S = 544

3S = 612

S = 204

Now that we know that 204 small bags of popcorn were sold, we can use the first equation to solve for L:

L + S = 289

L + 204 = 289

L = 85

Therefore, the movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.

So Katya's rectangular table is 1.6 meters long and 3/4 meters wide, with an area of 1 1/5 square meters.

Area is a measure of the size of a two-dimensional surface, such as the surface of a shape or object. It is usually measured in square units, such as square meters, square centimeters, square feet, or square inches. The area of a shape tells us how much surface area it covers, and is often used in a variety of fields, such as architecture, engineering, and physics. For example, the area of a room can help determine how much flooring is needed to cover it, the area of a building facade can help determine how much material is needed to cover it, and the area of a wing can help determine its lift and drag characteristics in aerodynamics.

Here,

Let's start by using the formula for the area of a rectangle:

A = lw

where A is the area, l is the length, and w is the width.

We are given that the width of the table is 3/4 meters, so we can substitute this value into the formula and simplify:

A = l(3/4)

l = (4/3)A

Next, we are told that the table has an area of 1 1/5 m^2. We can convert this mixed number to an improper fraction by multiplying the whole number by the denominator and then adding the numerator:

1 1/5 = (5*1 + 1)/5 = 6/5

So the area of the table is 6/5 m^2. Substituting this value for A in the formula above, we get:

l = (4/3)(6/5)

l = 8/5 m

Therefore, the length of the table is 8/5 meters, or 1.6 meters when converted to a decimal.

Using the Hamilton's method of apportioning of seats, the five countries will get the following number of seats:

Adams = 7

Grant =7

Colton= 11

Davis= 5

Hayes= 2

Total = 7+7+11+5+2 = 32 seats

To calculate the number of seats, first find the Standard Divisor (SD). That is: SD = Total population / Number of seats available

Total population = 213,000+225,000+351,000+158,000+70,000 = 1,017,000

Then divide the total population by number of seats available (32).

That is: SD = 1,017,000/32

SD = 31,781.25

Find the Standard Quota (SQ) for each county by using the formula;

SQ = County population / SD

Adam's SQ = 213,000/31,781.25 = 6.70

Grant's SQ = 225,000/31,781.25 = 7.08

Colton's SQ = 351,000/31,781.25 = 11.04

Davis's SQ = 158,000/31,781.25 = 4.97

Hayes's SQ = 70,000/31,781.25 = 2.20

Find the Lower Quota for each county and find the total number of occupied seats:

So overall, you can expect to make a profit of $166.67 if you play the game 100 times.

What is probability ?

Probability can be defined as the ratio of number of favourable outcomes and total number of outcomes.

To determine how much you expect to win or lose if you play the game 100 times, we need to calculate the expected value of each round and then multiply it by the number of rounds.

Let X be the random variable that represents the amount you win in one round of the game. The possible outcomes of X are winning $14, winning $12, or losing $10. We can calculate the expected value of X using the following formula:

E(X) = P(win $14) × $14 + P(win $12) × $12 + P(lose $10) × (-$10)

To calculate the probabilities, we can use the fact that there are 5 red balls, 3 green balls, and 4 yellow balls in the bag. The probability of drawing a red ball is therefore 5/12, the probability of drawing a green ball is 3/12, and the probability of drawing a yellow ball is 4/12.

So we have:

E(X) = (5/12) × $14 + (4/12) × $12 + (3/12) × (-$10)

E(X) = $5/3

This means that on average, you expect to win $5/3 per round. Over 100 rounds, you can expect to win:

100 × $5/3 = $166.67

However, it's important to note that this is just an average - in reality, you may win more or less than this amount depending on the luck of the draw.

Therefore, overall, you can expect to make a profit of $166.67 if you play the game 100 times.

The stated statement states that there are 360000 different ways to arrange them all in a line without any freshman standing close to one another.

Standing, also known as nov. 2, is a posture when the body is only supported by the feet while being held in an upright (orthostatic) position. The body moves slowly back and forth between the leg in the sagittal plane, although appearing to be immobile.

The total amount of ways they can position in a line without any further restrictions and the total amount of times they are standing in a line can both be included, but no undergraduates actually standing next to one another.

The answer we seek in accordance with the inclusion-exclusion principle is the difference between the two.

Furthermore take note of the phrase "Everyone is identifiable" in the issue, which suggests that "order matters."

The total number of configurations in which they can line up is the iteration of nine persons, which is:

P⁹ * 9 = 9! = 362880

The amount of different ways they can be in a line without standing close to one other is the next thing we take into account.

The sophomores will be taken into consideration initially. We have strategies for lining up the sophomores.

P⁴ * 4= 4! =24

But we haven't yet taken into account the freshman. Currently, we are not allowed to place two freshmen in front of or behind two sophomores, or between two freshmen. We shall take into account any location the freshman might possibly fit inside the line.

In the figure below, B stands for sophomores, and X for an open spot.

The line appears as follows once the sophomores have been taken into account:

X B X B X B X B X

Each freshman must move to an open area since no two undergraduates can fit in the exact same X place.

This is how the line will appear. (B stands for sophomores, G for freshmen)

G B G B G B G B G

The freshmen's order, however, has not been taken into account. They can be arranged in several ways.

P⁵ * 5 = 5!= 120 ways.

The number of sophomore arrangements and indeed the number of freshman arrangements are multiplied:

There are several methods to arrange them all in a line without any freshman standing near to one another.

Answer:

ok what is the question to your math equation then..?

Answer:study

Step-by-step explanation:

The solution is, the average speed of the boat relative to the water is 9 mph

Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Speed = Distance/ Time

here, we have,

Let x represent the speed of the boat.

The rate of the current was 7 mph,

Assuming the boat travelled against the current while going upstream, the total speed would be x - 7

Assuming the boat in the direction of the current while going downstream, the total speed would be x + 7

Time = speed × time

Since she travelled 32 miles upstream and 32 miles downstream, then,

Time taken to go upstream = 32/(x -7)

Time taken to go downstream = 32/(x + 7)

Since the total time of the trip was 18 hours, then

32/(x -7) + 32/(x + 7) = 18

Cross multiplying by (x - 7)(x + 7), it becomes

32(x + 7) + 32(x - 7) = 18[(x - 7)(x + 7)

32x + 224 + 32x - 224 = 18(x² + 7x - 7x - 49

32x + 32x = 18x² - 882

18x² - 64x - 882 = 0

Dividing through by 2, it becomes

9x² - 32x - 441 = 0

9x² + 49x - 81x - 441 = 0

x(9x + 49) - 9(9x + 49) = 0

x - 9 = 0 or 9x + 49 = 0

x = 9 or x = - 49/9

Since the speed of the boat cannot be negative, then x = 9
