Answer:

Step-by-step explanation:

Let's denote the length of the rectangle as 3x and the width as 2x, based on the given ratio.

The perimeter of a rectangle is given by the formula P = 2(length + width). In this case, we have:

P = 2(3x + 2x)

40 = 2(5x)

Now, let's solve for x:

40 = 10x

x = 40/10

x = 4

Now that we have the value of x, we can find the length of the rectangle:

Length = 3x = 3(4) = 12

Therefore, the length of the rectangle is 12.

Answer:

Sure, here is the inequality that represents the number of gigabytes of data (G) you can use to stay under your budget of $130:

```

cost_per_gb * G <= budget

```

where:

* cost_per_gb is the cost of data per gigabyte, which is $10 in this case

* G is the number of gigabytes of data

* budget is your budget, which is $130 in this case

To solve this inequality, we can first subtract cost_per_gb from both sides of the inequality. This gives us:

```

G <= budget / cost_per_gb

```

We can then plug in the values for cost_per_gb and budget to get:

```

G <= 130 / 10

```

```

G <= 13

```

This means that you can use up to 13 gigabytes of data and still stay under your budget. If you use more than 13 gigabytes of data, you will exceed your budget.

Here is a table that shows the cost of data for different amounts of data:

```

| Amount of data (G) | Cost (\$) |

The man is in the south direction from the starting point.

Let's visualize the movements of the man step by step:

The man starts by going 10 meters north.

He then turns left (which means he is now facing west) and covers 6 meters in that direction.

Next, he turns left again (which means he is now facing south) and walks 5 meters.

To determine the final direction of the man from the starting point, we can consider the net effect of his movements.

Starting from the north, he moved 10 meters in that direction. Then, he turned left twice, which corresponds to a 180-degree turn, effectively changing his direction by 180 degrees.

Since he initially faced north and then made a 180-degree turn, he is now facing south. Therefore, the direction he is in from the starting point is "south."

Answer:

Step-by-step explanation:

To determine the percentage of adults who had 2 children, we need to first find the total number of adults questioned.

Looking at the bar graph, we can see that the bar representing 2 children has a height of 2.5. This means that 2.5 adults indicated having 2 children.

Let's assume the total number of adults questioned is "m". According to the bar graph, the sum of the heights of all the bars represents the total number of adults questioned.

From the bar graph, we can see the following:

The bar representing 4+ children has a height of 4.

The bar representing 3- children has a height of 3.5.

The bar representing 2- children has a height of 2.5.

The bar representing 1- children has a height of 1.5.

The bar representing 1 child has a height of 1.

The bar representing 0.5- children has a height of 0.5.

The bar representing 0 children has a height of 0.

To find the total number of adults questioned (m), we sum up the heights of all the bars:

m = 4 + 3.5 + 3 + 2.5 + 2 + 1.5 + 1 + 0.5 + 0

m = 18

Therefore, the total number of adults questioned is 18.

To find the percentage of adults who had 2 children, we divide the number of adults with 2 children (2.5) by the total number of adults questioned (18) and multiply by 100:

Percentage = (2.5 / 18) * 100

Percentage ≈ 13.9 (rounded to 1 decimal place)

Therefore, approximately 13.9% of the adults questioned had 2 children.

The area of the region bounded by the graphs of [tex]f(x) = x^3 + x^2 - 6x[/tex] and [tex]g(x) = 2x - x^2[/tex] is 69 1/3 square units.

To find the area of the region bounded by the graphs of the functions [tex]f(x) = x^3 + x^2 - 6x[/tex] and [tex]g(x) = 2x - x^2[/tex], we need to determine the points of intersection and evaluate the definite integral.

First, let's find the points of intersection by setting f(x) equal to g(x):

[tex]x^3 + x^2 - 6x = 2x - x^2[/tex]

Rearranging the equation, we get:

[tex]x^3 + 2x^2 - 8x = 0[/tex]

Factoring out an x, we have:

[tex]x(x^2 + 2x - 8) = 0[/tex]

Using the quadratic formula, we find the solutions for [tex]x^2 + 2x - 8 = 0[/tex] to be x = -4 and x = 2. Therefore, the points of intersection are (-4, -16) and (2, 4).

To calculate the area, we integrate the difference of the two functions within the bounds of -4 to 2:

Area = ∫[from -4 to 2] (f(x) - g(x)) dx

Evaluating the definite integral, we have:

Area = ∫[-4 to 2] [(x^3 + x^2 - 6x) - (2x - x^2)] dx

= ∫[-4 to 2] (x^3 + 2x^2 - 8x) dx

Integrating each term and evaluating the integral, we find:

Area = [1/4x^4 + 2/3x^3 - 4x^2] from -4 to 2

= [(1/4)(2)^4 + (2/3)(2)^3 - 4(2)^2] - [(1/4)(-4)^4 + (2/3)(-4)^3 - 4(-4)^2]

= [4/4 + 16/3 - 16] - [16/4 + (-128/3) - 64]

= 1/3 + 128/3 - 16 + 4 - 128/3 + 64

The difference in size between the two guys is approximately -0.3108 inches, which implies that the first guy is bigger than the second guy.

To calculate the difference in size between two people, one measuring in inches and the other measuring in centimeters, we must first convert all measurements to a common unit.

Guy measures 3 inches + 1/4 inch. We can convert 1/4 inch to a decimal fraction by dividing 1 by 4, which gives us 0.25 inches. So your measurement in inches would be 3 + 0.25 = 3.25 inches.

The other guy measures 9.045 cm. To convert centimeters to inches, we use the following relationship: 1 cm = 0.3937 inches. Multiplying the measurement in centimeters by 0.3937, we get the measurement in inches: 9.045 cm * 0.3937 = 3.5608 inches (approximately).

Now we can calculate the size difference between them. We subtract the measurement of the second chavo (3.5608 inches) from the measurement of the first chavo (3.25 inches):

3.25 inches - 3.5608 inches = -0.3108 inches.

The resulting difference is -0.3108 inches. This means that the second chavo is smaller in size than the first. Since the difference is negative, it indicates that the first chavo is bigger than the second.

In summary, the difference in size between the two guys is approximately -0.3108 inches, which implies that the first guy is bigger than the second guy.

The total volume of the dill spears is approximately 1013 cm³.

To find the total volume of the dill spears, we can use the formula for the volume of a cylinder, which is given by V = πr²h,

where V is the volume, r is the radius of the base, and h is the height of the cylinder.

First, let's find the radius of the base.

Since the area of the base is given as 45 cm², we can use the formula for the area of a circle,

A = πr², to solve for the radius.

Rearranging the formula, we have r = √(A/π).

Given that the area of the base is 45 cm², we can substitute this value into the formula to find the radius:

r = √(45/π) ≈ 3 cm (rounded to the nearest centimeter)

Now that we have the radius and the height of the jar, we can calculate the volume of the jar using the formula V = πr²h:

V = π(3²)(13) ≈ 1173 cm³ (rounded to the nearest cubic centimeter)

However, we need to subtract the volume of the pickle juice that was drained from the jar.

We are given that the amount of pickle juice is 160 cm³, so the total volume of the dill spears is:

Total volume = Volume of jar - Volume of pickle juice = 1173 cm³ - 160 cm³ = 1013 cm³

Hope this helps and have a nice day

Step-by-step explanation:

To find the probability that a student is accepted at FSU or accepted at UF, we can use the concept of conditional probability and the law of total probability.

Let's denote the events as follows:

A: Accepted at FSU

B: Accepted at UF

We need to find P(A or B), which can be calculated as the sum of the probabilities of each event minus the probability of their intersection:

P(A or B) = P(A) + P(B) - P(A and B)

Given the information provided, we can calculate the probabilities:

P(A) = 0.4 (40% chance of being accepted at FSU)

P(B|A) = 0.6 (60% chance of being accepted at UF if accepted at FSU)

P(B|A') = 0.9 (90% chance of non-acceptance at UF if not accepted at FSU)

P(A and B) = P(A) * P(B|A) = 0.4 * 0.6 = 0.24 (probability of being accepted at both FSU and UF)

Now we can substitute these values into the formula:

P(A or B) = P(A) + P(B) - P(A and B)

= 0.4 + (1 - 0.4) * P(B|A') - P(A and B)

= 0.4 + 0.6 * 0.9 - 0.24

= 0.4 + 0.54 - 0.24

= 0.7

Therefore, the probability that a student is accepted at FSU or accepted at UF is 0.7, or 70%.

a. The interval of time between eruptions if the previous eruption lasted 4 minutes is 86.51 minutes.

b. The residual for this cycle is 2.07 minutes.

c. The interval of time between eruptions lasted for 2.07 minutes than the regression line equation predicted.

d. The slope of the regression line means that the interval of time between eruptions increases by 13.29 minutes for every additional minute of the previous eruption.

e. No, the value of the y-intercept doesn't have meaning in the context of the problem.

Based on the information provided above, the relationship between the duration of the previous eruption (x in minutes) and the interval of time between eruptions (y in minutes) is modeled by this regression line equation:

ÿ = 33.35 + 13.29x

Part a.

When x = 4 minutes, the value of is given by:

ÿ = 33.35 + 13.29(4)

ÿ = 86.51 minutes.

Part b.

The residual for the given cycle can be calculated as follows;

Residual = y - ÿ

Residual = 62 - (33.35 + 13.29(2))

Residual = 62 - 59.93

Residual = 2.07 minutes.

Part c.

Based on the calculation above, we can logically deduce that the interval of time between eruptions lasted for 2.07 minutes than the equation of regression line predicted.

Part d.

The slope of the regression line is equal to 13.29 and it implies that the interval of time between eruptions increases by 13.29 minutes for every additional minute of the previous eruption.

Part e.

In the context of the problem, we can logically deduce that the value of the y-intercept doesn't have any meaning because the duration of the previous eruption cannot be equal to 0 minutes.

The periods of daylight and darkness on that day are approximately:

Daylight: 202.5°

Darkness: 157.5°

Hence, the correct option is:

C. 202°3°, 157°30'

To calculate the periods of daylight and darkness on a certain day, we need to find the difference between the times of sunrise and sunset.

Sunrise time: 5.30 am

Sunset time: 7.00 pm

To find the period of daylight, we subtract the sunrise time from the sunset time:

Daylight = Sunset time - Sunrise time

First, let's convert the times to a 24-hour format for easier calculation:

Sunrise time: 5.30 am = 05:30

Sunset time: 7.00 pm = 19:00

Now, let's calculate the period of daylight:

Daylight = 19:00 - 05:30

To subtract the times, we need to convert them to minutes:

Daylight = (19 * 60 + 00) - (05 * 60 + 30)

Daylight = (1140 + 00) - (330)

Daylight = 1140 - 330

Daylight = 810 minutes

To convert the period of daylight back to degrees, we can use the fact that in 24 hours (1440 minutes), the Earth completes a full rotation of 360 degrees.

Daylight (in degrees) = (Daylight / 1440) * 360

Daylight (in degrees) = (810 / 1440) * 360

Daylight (in degrees) ≈ 202.5 degrees

To find the period of darkness, we subtract the period of daylight from a full circle of 360 degrees:

Darkness = 360 - Daylight

Darkness = 360 - 202.5

Darkness ≈ 157.5 degrees

Therefore, the periods of daylight and darkness on that day are approximately:

Daylight: 202.5°

Darkness: 157.5°

Answer: 2 1/2 pounds of more clay

Step-by-step explanation:

To calculate how much more clay Ms. Garcia needs, we need to add up the clay requirements for each grade level and then subtract the amount she already has.

For the sixth graders:

Number of students: 25

Clay required per student: 3/4 pound

Total clay required for sixth graders: 25 * (3/4) = 75/4 = 18 3/4 pounds

For the seventh graders:

Clay required for sculptures: 20 pounds

Total clay required for both grade levels: 18 3/4 + 20 = 38 3/4 pounds

Clay leftover from last year: 5 2/5 pounds

To find out how much more clay Ms. Garcia needs, we subtract the clay she already has from the total required:

38 3/4 - 5 2/5 = 38 3/4 - 27/5 = 38 3/4 - 27/5 = (155 - 108 + 3)/20 = 50/20 = 5/2 = 2 1/2 pounds

Therefore, Ms. Garcia needs an additional 2 1/2 pounds of clay.

The loan principal is $12,483.33, and the loan's maturity value is $15,479.33.

To calculate the loan principal, we can use the formula for simple interest:

Interest = Principal x Rate x Time

Given that Rebecca earned $2,996 as interest, the rate is 2.00% per month (or 0.02), and the time is 12 months, we can plug in these values into the formula and solve for the principal:

$2,996 = Principal x 0.02 x 12

$2,996 = Principal x 0.24

Dividing both sides of the equation by 0.24, we get:

Principal = $2,996 / 0.24

Principal = $12,483.33

So, the loan principal is $12,483.33.

To calculate the loan's maturity value, we need to add the principal and the interest earned. Since the interest earned is $2,996 and the principal is $12,483.33, the maturity value can be calculated as:

Maturity Value = Principal + Interest

Maturity Value = $12,483.33 + $2,996

Maturity Value = $15,479.33

Therefore, the loan's maturity value is $15,479.33.
