Step-by-step explanation:

The value of the variable 'x' is 12.5. Then the perimeter of the ΔJHI is 50 units.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ΔGEF and ΔJHI are similar triangles. Then the equation is given as,

5 / x = 8 / 20

5 / x = 2 / 5

x = 25/2

x = 12.5

The perimeter of the ΔJHI is given as,

P = 17.5 + 20 + 12.5

P = 50 units

The value of the variable 'x' is 12.5. Then the perimeter of the ΔJHI is 50 units.

Answer:

8500 ft²

Step-by-step explanation:

First we need to find the area of the non shaded region within this shaded region. To find the area of this non shaded rectangle, use the formula base×height.

20×100=2000 ft².

Now we need to find the height and width of the shaded region which is,

25+25+20=70 Height

25+25+100=150 Width

mutiply these numbers 150×70=10500 ft²

Now we just need to subtract that inside area.

10500-2000=8500 ft²

The probability of randomly choosing a green marble after you have chosen red is 4.4%

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Given

A jar has 20 marbles: 3 green, 12 blue, 5 red.

Probability;

In probability theory, an event is a set of outcomes of an experiment or a subset of the sample space.

The total number of marbles = 20

The number of green marbles= 3

The number of blue marbles = 12

The number of red marbles = 5

The probability of choosing a red marble = Number of red marbles / Total number of marbles

= 5/20

The probability of choosing a green marble is =  Number of green marbles / New total number of marbles

= 3/19

Therefore,

The probability of randomly choosing a green marble after you have chosen red is;

= 5/20 * 3/19

= 3/68

percentage = 3/68 * 100 = 4.4%

Hence, the probability of randomly choosing a green marble after you have chosen red is 4.4%

Answer:

  x = -2 and x = 1/3

Step-by-step explanation:

The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.

The solutions are x = -2 and x = 1/3.

__

One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.

  -6 = (-1)(6) = (-2)(3) = ...

The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...

  3x^2 -x +6x -2 = 0

Factoring pairs of terms, we have ...

  x(3x -1) +2(3x -1) = 0

  (x +2)(3x -1) = 0

The solutions are the values of x that make these factors zero:

  x + 2 = 0   ⇒   x = -2

  3x -1 = 0   ⇒   x = 1/3

The solutions are x = -2 and x = 1/3.

Step-by-step explanation:

First find 5 percent of 30 which is 5 divided by 100 multiplied by 30 then add the answer to 30 to get the answer to the question

Answer:

Percent error = -4.02 (Approx.)

Step-by-step explanation:

Given:

Estimated pool dimension = 15 ft long and 35 ft wide

Actual pool dimension = 14.5 ft long and 34.75 ft wide

Find:

Percent error

Computation:

Area of Estimated pool = 15 x 35

Area of Estimated pool = 525 ft²

Area of Actual pool = 14.5 x 34.75

Area of Actual pool = 508.875 ft²

Percent error = [(Actual - Estimated) / Estimated]100

Percent error = [(508.875 - 525) / 525]100

Percent error = [(-21.125) / 525]100

Percent error = -4.02 (Approx.)

Answer:

2x

Step-by-step explanation:

Think about it. Adding 8 would make the equation: 3x+8=3x+8. That has infinite solutions.  if you made it 7, it would be 3x+8=3x+7, which is impossible.  

Therefore, it must be 2x, which would make the equation 3x+8=5x.

Let's check: 3x+8=5x

                     8=2x

                     4=x

All good.

The equivalent expression to the sentence "9 more than the quotient of x and 5" is given as follows:

-19.99; The line of best fit underpredicts the student's science test score.

So correct option is A.

A prediction is an estimation or forecast about future events or conditions, based on past data and trends, current information, and/or mathematical models. Predictions can be made in various fields, such as finance, weather, sports, social sciences, and natural sciences. The accuracy of predictions depends on many factors, including the quality of the data used, the assumptions made, the complexity of the system being analyzed, and the reliability of the methods used. Predictions are not always accurate and are often subject to revision as new information becomes available.

The predicted science score for the student with IQ 100 can be calculated using the line of best fit:

ŷ = −20.3 + 0.7489 * 100 = 71.59

The residual is the difference between the actual science test score and the predicted science score:

residual = actual score - predicted score = 52.6 - 71.59 = -19.99

So the line of best fit underpredicts the student's science test score by 19.99 points.

Therefore, the residual is:

Answer:

12

Step-by-step explanation:

Given that,

f(x) = 2x² - 3x + 7

To find the value of f ( 2.5 ), replace x with 2.5 and solve the equation.

Let us solve it now.

f(2.5) = 2(2.5)² - 3×2.5 + 7

f(2.5) = 12.5 - 7.5 + 7

f(2.5) = 12

Answer:

\(f(x) = 2 {x}^{2} - 3x + 7 \\ f(2.5) = 2 {(2.5)}^{2} - 3(2.5) + 7 \\ f(2.5) = 12.5 - 7.5 + 7 \\ \boxed{f(2.5) = 12}\)

We would apply the formula for finding net profit which is expressed as

Net profit = gross profit - expenses

In this case, it is

net profit = gross annual profit - annual operating expenses

From the information given,

gross annual profit = $394,840

annual operating expenses = $196,900

Thus,

Net profit = 394840 - 196900

Net profit = $197940

The 6 number of muffins in each box if they all contain the same amount of muffins.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Jill made 20 muffins.

She put them into 3 boxes and has 2 muffins left.

That means,

muffins in the boxes =20 -2

                              = 18 muffins are in the boxes.

To find the number of muffins in each box if they all contain the same amount of muffins:

Divide the rest of the muffins to 3.

Number of muffins in the boxes / 3

= 18 / 3

= 6

Therefore, six muffins are in each box.

Answer:

sorry I can see the whole answer on the image

You posted a lot of questions. I'll do the first three to get you started.

==================================================

Problem 1

Explanation:

Draw a vertical line to enclose the un-shaded region. Think of it like adding fencing to enclose a paddock or backyard.

What results are two rectangles. The larger rectangle has area = length*width = 8*10 = 80 square inches.

The smaller unshaded rectangle inside has area of 5*5 = 25 square inches.

The difference of those areas is:  80-25 = 55

You have the correct answer. Nice work.

==================================================

Problem 2

Explanation:

Follow the same set of steps as done in the previous problem. Draw a vertical line to form a larger rectangle.

The larger rectangle has area of 18*31.5 = 567 square feet.

The smaller unshaded rectangle has area of 9*9 = 81 square feet.

Subtract those results to get the shaded region only: 567-81 = 486

==================================================

Problem 3

Explanation:

This time we don't have to add any extra lines to enclose the figure.

A = larger area = 6*2.4 = 14.4

B = smaller unshaded area = 2*4.4 = 8.8

C = A-B = 14.4-8.8 = 5.6 square cm

You have the correct answer. Nice work.

Answer:

1)  55 in²

2)  486 ft²

3)  5.6 cm²

Step-by-step explanation:

To calculate the area of each given figure, subtract the area of the cut-out rectangle (marked in blue on the attached diagram) from the area of the larger rectangle.

\(\boxed{\begin{minipage}{5cm}\underline{Area of a rectangle}\\\\$A=w\cdot l$\\\\where:\\ \phantom{ww} $\bullet$ \quad $w$ is the width.\\ \phantom{ww} $\bullet$ \quad $l$ is the length.\\\end{minipage}}\)

\(\begin{aligned}\textsf{Total Area}&=\textsf{Larger rectangle}-\textsf{Cut-out rectangle}\\&=8 \cdot 10- 5\cdot 5\\&=80-25\\&=55\; \sf in^2\end{aligned}\)

\(\begin{aligned}\textsf{Total Area}&=\textsf{Larger rectangle}-\textsf{Cut-out rectangle}\\&= 31.5\cdot 18- 9\cdot 9\\&=567-81\\&=486\; \sf ft^2\end{aligned}\)

\(\begin{aligned}\textsf{Total Area}&=\textsf{Larger rectangle}-\textsf{Cut-out rectangle}\\&= 6\cdot 2.4- 4.4\cdot2 \\&=14.4-8.8\\&=5.6\; \sf cm^2\end{aligned}\)
