The perimeter of a rectangle is 100 ft , if the wife is 20 ft what is the value of the length?

Answers

Answer:

30

Step-by-step explanation:

since the width is 20, there are 2 sides, so multiply by 2 and it's 40. Subtract 40 from 100 and you get 60. 60 is both lengths combined, so divide by 2 and you have 30 as your length. :)

just took notes on subject and know answer. 100% sure its right

The slope of the LlNE 1 is negativeFor the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of LINE  2 will be UNDEFINEDThe slope of LlNE 3 is positiveFor the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE  4 will be ZERO

The slope of a line is determined by its steepness.

The formula for calculating slope is expressed as;

[tex]\frac{\triangle y}{\triangle x} = \frac{y_2-y_1}{x_2-x_1}[/tex]

For the first graph, we can assume the coordinates (-1, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0_1}{0-(-1)}\\\frac{\triangle y}{\triangle x} = \frac{-2}{1}\\\frac{\triangle y}{\triangle x} = -2\\\\[/tex]

Since the slope is -2 which is a negative value, hence the slope of LlNE 1 is negative

For the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of  LINE  2 will be UNDEFINED

For the THIRD graph, we can assume the coordinates (2, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0}{0-2}\\\frac{\triangle y}{\triangle x} = \frac{-2}{-2}\\\frac{\triangle y}{\triangle x} = 1\\\\[/tex]

Since the slope is 1 which is a negative value, hence the slope of LlNE 3 is positive

For the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE  4 will be ZERO

Suppose it takes John 18 minutes to run 3 miles. How long would it take him to run 7 kilometers? round to the nearest minute

Answers

Answer: 26 Minutes

Step-by-step explanation:

3 mi * 1.609 km/1 mi = 4.82 km

4.82 km/ 18 minutes = 7 km/ x minutes

4.82x=18*7

x=126/4.82

x=26.14 ~ 26 Minutes

One mile contains  1 mile = 1.690KM.

According to the if we convert 7km into miles 4.3496 miles. Thus the correct answer for the question is 26 minutes  

Explanation:

That its taken the when john runs 18 minutes for 3 miles that is km4.82 than if we consider 1.34 miles is required to be covered more when subtract the value 4.3496-3.0000-1.34miles it should be 13is half of it multiply by 2 minutes more is required to cover the left distance is carried by Dividing 18by 1.34 and multiplying by 2

Answers

Answer:

Step-by-step explanation:

The total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Zoe bought 1.5 pounds of apples for $3.50 per pound.

Let x be the total cost of the product:

x = 3.50x1.5

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

x = $5.25

Thus, the total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.

Truckco manufactures two types of trucks: 1 and 2. Each truck must go through the painting shop and assembly shop. If the painting shop were completely devoted to painting Type 1 trucks, then 800 per day could be painted; if the painting shop were completely devoted to painting Type 2 trucks, then 700 per day could be painted. If the assembly shop were completely devoted to assembling truck 1 engines, then 1,500 per day could be assembled; if the assembly shop were completely devoted to assembling truck 2 engines, then 1,200 per day could be assembled. Each Type 1 truck contributes $300 to profit; each Type 2 truck contributes $500. formulate an LP that will maximize Truckco’s profit.

Answers

Answer:

Step-by-step explanation:

Let y represent type 2 truck and x represent type 1 truck. The painting can be represented by the inequality:

[tex]\frac{x}{800}+\frac{y}{700}\leq 1[/tex]                  (1)

The assembling can be represented by the inequality:

[tex]\frac{x}{1500}+\frac{y}{1200} \leq 1[/tex]                (2)

Also, x, y ≥ 0

The objective function is given as:

max z = 300x + 500y

Plotting 1 and 2 using online geogebra

From the graph, the optimal value is at (0,700). Hence:

max z = 300(0) + 500(700) = $350000

Answer:

x = 25

Step-by-step explanation:

It is given that, ray Ray AP bisects angle CAT. It means,

[tex]\angle CAT=\angle CAP+\angle PAT[/tex]

Also, [tex]\angle CAP = \angle PAT[/tex]

It gives, [tex]\angle CAT=2\angle PAT[/tex]

ATQ,

[tex]\angle CAT = 5x+17 \ \text{and}\ \text{PAT}=3x-4[/tex]

So,

[tex]5x+17=2(3x-4)\\\\5x+17=6x-8[/tex]

Taking like terms together,

[tex]5x-6x=-8-17\\\\-x=-25\\\\x=25[/tex]

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

The slope of the linear function is -6

What is slope?

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as, dx/dy.

here, we have,

Method used for finding the slope

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

m = y2 - y1/x2-x1

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

m = -6

The slope of the linear function, m = -6

Which of the following is an informal proof of the given conjecture? Conjecture: All squares are similar

Answers

Answer:

the last one, i just got 100%

Step-by-step explanation:

Option 4 : Square A has side lengths a₁ =3, a₂= 3 and Square B has side lengths b₁=6,b₂=6 Then show that the ratio of corresponding side length is equal:  a₁ /a₂=b₁/b₂,  3/3=6/ 6  is the informal proof of the given conjecture.

What is informal proof?

Informal proofs are used to proof a theorem in different methods of  proving theorems and steps of the proof are not formally framed.

Mostly by taking a particular example a theorem is proved.

All square are similar.

This statement is true

Option 1 is false

Option 2 is formal proof as sides of squares A and B are taken as variables x and y therefore this proof can be used for any pair of two squares

Option 3. is wrong proof as the  two sides of square A and B are taken unequal but square has all four sides equal.

Option 4 is correct proof but it is not a formal one as a particular example is taken to proof with statement

Therefore option 4 is the correct option that show the informal proof of the given statement.
