The required area of the frame shown is 5x + 3. Option C is correct.

The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.

Here,
The area of the picture is given as,
= 2x × x
= 2x²

The area of the whole painting with frame.

= (x + 1)(2x+ 3)
= 2x² + 5x + 3

The area of the frame is given as,
= area of picture with frame - an area of the picture,
= 2x² + 5x + 3 - 2x²

Answer:

the approximate value of m is -0.12, indicating that the value of Ty's computer decreases by 0.12 (or 12%) each year.

Step-by-step explanation:

o express this depreciation rate as a slope in the equation y = mx + b, we need to determine how much the value changes (the "rise") for each year (the "run").

Since the value decreases by 12% per year, the slope (m) would be -12%. However, we need to express the slope as a decimal, so we divide -12% by 100 to convert it to a decimal:

m = -12% / 100 = -0.12

The Relative Maximum will be (7, 50) and minimum is (12, 0).

We have the graph showing average low temperatures in international falls minnesota.

From the graph the maximum y coordinate is 50.

So, the Relative Maximum will be (7, 50).

and, the minimum y coordinate is 0.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

Answer:

Confidence Interval = (1.41, 1.59)

Step-by-step explanation:

To construct a confidence interval for the population mean, we can use the following formula:

Confidence Interval = sample mean ± (margin of error * standard error)

where the standard error is equal to the standard deviation divided by the square root of the sample size.

Given the information provided, we can calculate the standard error as:

standard error = 2.16 / sqrt(1370) = 0.058

Then, we can calculate the margin of error as 0.12.

Substituting these values into the formula, we get:

Confidence Interval = 1.5 ± (0.12 * 0.058)

Confidence Interval = (1.41, 1.59)

Therefore, we can interpret the 95% confidence interval as follows: we are 95% confident that the true population mean of the number of days that people feel lonely in the past 7 days is between 1.41 and 1.59. This means that if we were to take many samples of 1370 subjects and compute the confidence intervals for each sample using the same method, we would expect about 95% of the intervals to contain the true population mean.

Amount of dividend that PRH will receive is $833,625.

Step-by-step explanation:

The following are given in the question:

Total number of shares of Marks Brothers = 78,000

Percentage of shares of Marks Brothers held by PRH = 19%

Dividend per share = $56.25

Therefore, we can now proceed as follows:

Number of shares of Marks Brothers held by PRH = Total number of shares of Marks Brothers * Percentage of shares of Marks Brothers held by PRH = 78,000 * 19% = 14,820

Amount of dividend that PRH will receive = Number of shares of Marks Brothers held by PRH * Dividend per share = 14,820 * $56.25 = $833,625

The amount of dividend that PRH will receive is $833,625.

Number of shares of Marks Brothers held by PRH is

= Total number of shares of Marks Brothers × Percentage of shares of Marks Brothers held by PRH

= 78,000 × 19%

Let's assume that there are 100 houses in her neighborhood. then 89 of them have garages and 48 of them have garages and pools. 48 / 89 = about 0.5393. Conver this to percent and we get 53.9

Katie spent approximately $285.544 on fuel during her vacation in Australia.

The Average Cost is the per unit cost of the product received by dividing the total cost (TC) by the total output (Q). By per unit cost of production, we mean that all the fixed and variable costs are considered for calculating the average cost. Thus, it is also called Per Unit Total Cost.

Symbolically, the average cost is expressed as:

AC = TC/Q

To estimate how much Katie spent on fuel, you need to multiply the number of gallons of gas she used (56 gallons) by the average cost of gas per gallon ($5.099):

56 gallons × $5.099/gallon = $285.544

So, Katie spent approximately $285.544 on fuel during her vacation in Australia.

Answer:

(-1, 5)

Step-by-step explanation:

this is correct

The new coordinates of the vector (5,1) after rotating it 90° clockwise about the origin would be (-1,5).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Rotating a vector 90° clockwise in a 2D coordinate system can be accomplished by "flipping" the vector's x and y coordinates and then negating one of them.

In this case, the original x-coordinate is 5 and the y-coordinate is 1.

When we negate the x-coordinate and swap the positions of x and y, we get the new coordinates of (-1,5).

Answer:

\(y =\frac{x}{4}\)

Step-by-step explanation:

We are given several functions, and we want to figure out which one is linear.

A linear function has both of its variables (x and y) with a power of 1. Variables with other powers do not mean that the function is linear.

Let's go through the list.

Starting with \(y=\frac{3}{x} -7\), we can see that x is in the denominator. If this is the case, it means that the power of x is -1.

Even though y has a power of 1, this is NOT linear, because x has a power of -1.

Now, with y=√x-2, this is also not linear. This is because √x = \(x^\frac{1}{2}\), even though y has a power of 1.

For x² - 1 = y, we can clearly see that x has a power of 2, while y has a power of 1. This means that the function is not linear.

This leaves us with \(y = \frac{x}{4}\). x is in a fraction, however it is not in the denominator. This means that the power of x in this function is 1. We can also see that the power of y in this function is 1.

This means that \(y=\frac{x}{4}\) is linear.

Step-by-step explanation:

The amount of 4​% butterfat milk  is equal to x quarts , When 1​% butterfat milk  is equal to 75-x. The amount of butterfat in 4​% butterfat milk is x/100*4=0.04x

The amount of butterflat in 1​% butterfat milk is (75-x)/100= 0,75-0.01x

1​The amount of butterflat in 75 quarts of 3​% butterfat milk (our desired mixture) is 75/100*3= 2.25

This quantity (2.25) is the sum of butterfat from  4​% butterfat milk and 1​% butterfat milk(the sum of 0.04x and 0.75-0.01x)

the equation is

0.04x+0.75-0.01x=2.25

0.03x=1.5

x=50

Answer:

D

Step-by-step explanation:

To solve this problem, we can use algebra. Let's call the amount invested at 5% "x" and the amount invested at 8% "y".

We know that:

x + y = $20,000 (because this is the total amount Candace had to invest)

We also know that:

0.05x + 0.08y = $1435 (because this is the total income from the two investments, and we need to use the percentage rates to calculate the income)

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y:

y = $20,000 - x

We can substitute this expression for y into the second equation:

0.05x + 0.08($20,000 - x) = $1435

0.05x + 0.08($20,000) - 0.08x = $1435

0.05x - 0.08x = $1435 - 0.08($20,000)

-0.03x = $1435 - $1600

-0.03x = -$165

x = $5500

So, Candace invested $5500 at 5%. To find how much she invested at 8%, we can use one of the original equations:

x + y = $20,000

$5500 + y = $20,000

y = $20,000 - $5500

y = $14500

Therefore, Candace invested $14500 at 8%

The answer is d) $5500 at 5% and $14500 at 8%
