Given: KLMN is a trapezoid, m∠N=m∠KML, FD=8, LM KN = 3/5 F∈ KL , D∈ MN , ME ⊥ KN KF=FL, MD=DN, ME=3root5 Find: KM

Step-by-step explanation:

We have been given an equation y+6=45(x+3) in point slope form.

It says to use the point and slope from given equation to create the graph.

So compare equation y+6=45(x+3) with point slope formula

y-y1=m(x-x1)

we see that m=45, x1=-3 and y1=-6

Hence first point is at (-3,-6)

slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).

Now we just graph both points (-3,-6) and  (-2,39) and join them by a straight line. Final graph will look like the attached graph.

Answer:

10 five-point questions and 40 two-point questions

Step-by-step explanation:

Let x represent the total number of five-point questions and y represent the total number of two-point questions.

Equation 1:     5x+2y=130

Equation 2:     x+y=50

Multiplying Equation 2 by 2:     2x+2y=100     (Equation 3)

(Equation 1) - (Equation 3):     3x=30

                                                  x=10

Substituting x=10 into x+y=50:     10+y=50

                                                            y=40

Therefore, there are 10 five-point questions and 40 two-point questions.

Substituting x=10 and y=40 into Equation 1:

LHS=5x+2y=5(10)+2(40)=50+80=130

RHS=130

LHS=RHS

Substituting x=10 and y=40 into Equation 2:

LHS=x+y=10+40=50

RHS=50

LHS=RHS

Since in both cases the left-hand side is equal to the right-hand side, the answer is correct.

(LHS: left-hand side, RHS: right-hand side)

Final answer:

To find the number of five-point questions on the test, set up an equation using the given information and solve for x.

Explanation:

To find the number of five-point questions on the test, we need to first determine the total number of points available. The test is worth 130 points, and there are a total of 50 five-point and two-point questions. Let's denote the number of five-point questions as x.

The total points from the five-point questions would be 5x, and the total points from the two-point questions would be 2(50 - x) = 100 - 2x. Since the test is worth 130 points, we can set up the equation 5x + 100 - 2x = 130.

Simplifying the equation, we get 3x + 100 = 130. Solving for x, we subtract 100 from both sides, resulting in 3x = 30, and then divide both sides by 3, giving us x = 10. Therefore, there are 10 five-point questions on the test.

Answer: x = 8

Step-by-step explanation:

4x + 18  +  5x  =  90

9x + 18 = 90             Added like terms

9x = 72                    Subtracted 18 from both sides

x = 8                       Divided both sides by 9

BONUS: The sum of these two angles is 90°, which means these angle are complementary.

Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = [tex]\frac{(y-y')}{(x-x')}[/tex]

                     slope   = [tex]\frac{(1-0)}{(0-0.5)}[/tex]

                                 = ( -2 )  

Therfore, Option A will be the answer.

The rate of change of function is,

m = - 2

We have to given that,

A function is shown in figure.

Since, The rate of change of linear function is slope of line.

Here, Two points on the line are (1, - 1) and (0, 1)

Since, The equation of line passes through the points (1, - 1) and (0, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-1)) / (0 - 1)

m = 2 / - 1

m = - 2

So, The rate of change of function is,

m = - 2

Step-by-step explanation:

Answer:

4 and 5

Step-by-step explanation:

Consider whole numbers 1, 2, 3, 4, 5, 6, ... and their squares

[tex]1^2=1,\\ \\2^2=4,\\ \\3^2=9,\\ \\4^2=16,\\ \\5^2=25,\\ \\6^2=36,...[/tex]

The number [tex]\sqrt{24}[/tex] has a square [tex](\sqrt{24})^2=24.[/tex]

Since [tex]16<24<25,[/tex] you can conclude that

[tex]4<\sqrt{24}<5.[/tex]

Thus, two consecutive whole numbers that [tex]\sqrt{24}[/tex] lies between are 4 and 5.

Final answer:

√24 lies between the consecutive whole numbers 4 and 5 because 4² is 16 and 5² is 25, and 24 is between these two perfect squares.

Explanation:

To find two consecutive whole numbers that √24 lies between, we should first identify the perfect squares that are closest to 24 but less than and greater than 24.

The perfect square less than 24 is 4², which is 16, and the perfect square greater than 24 is 5², which is 25. Since √24 is greater than √16 (which is 4) and less than √25 (which is 5), √24 lies between the whole numbers 4 and 5.

Transformation Shifted by 4 units right and 2 units down .

Step-by-step explanation:

Given  : Graph .

To find : Which type of transformation maps ABC to A'B'C.

Solution : We have given graph with  transformation maps ABC to A'B'C.

Coordinates of A ( -3 , 2) , B( -2 ,4) , C( -1 ,3) .

Coordinates of A' (1 , 0) , B'( 2 ,2) , C'( 3 ,1) .

We can see from given graph triangle ABC is shifted right ( x axis) by 4 units and move down by 2 units (y axis ).

Then

A ( -3 + 4 , 2 -2) →→A' (1 , 0)

B( -2+4 ,4 -2)  →→  B'( 2 ,2)

C( -1+ 4 ,3 -2)  →→ C'( 3 ,1) .

Therefore, Transformation Shifted by 4 units right and 2 units down .

The equation is linear because it is in the form y = mx+b, which is slope intercept form

m = 2 is the slope

b = -5 is the y intercept

Graphing y = 2x-5 produces a straight line.

The equation y=2x-5 is linear because it fits the form y = a + bx, with a straight-line graph and a direct relationship between x and y.

The equation y=2x-5 is a linear equation. In the form y = a + bx, a is the y-intercept, and b represents the slope.

Here, -5 is the y-intercept, and 2 is the slope of the equation, indicating how much y changes for each unit increase in x.

This linear equation can be graphed as a straight line.

The structure is similar to other linear equations like 7y = 6x + 8 and y + 7 = 3x, which are also represented by straight lines on a graph.

Linear relationships model a direct correlation between two variables, making them suitable for analysis with techniques like linear regression.

In practice, finding a relationship between an independent variable, such as hours worked on a car, and a dependent variable, like labor charges (y = 55x + 75), showcases a real-world example of linear equations.

Answer:

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

[tex]\frac{13}{100} =\frac{2600}{x}[/tex]

We begin solving by cross multiplying numerator to denominator of each fraction.

[tex]13(x)=100(2600)\\13x=260000\\\frac{13x}{13}=\frac{260000}{13}  \\20,000=x[/tex]

Answer:

the company's total budget is 20,000

Step-by-step explanation:

A company spends 13% of its month budget on rent which total $2600

Let x be the month budget on rent

13% of the month budget is 2600

13% can be written as 13/100

[tex]\frac{13}{100} \cdot x=2600[/tex]

Now we solve for x

multiply both sides by 100

[tex]13x= 260000[/tex]

divide both sides by 13

x=20000

So, the company's total budget is 20,000

Answer:

I think what you should do is 2/3 + 3/5 and then sutract it from the 2-ounce tube or you can do 2/15 - 2-ounces.

Step-by-step explanation:

Shelby used [tex]\frac{9}{15}[/tex]  or [tex]\frac{3}{5}[/tex]  ounce to paint the flag.

To determine how much paint Shelby used to paint her flag then, we have:

= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] + [tex]\frac{2}{15}[/tex]   (let solve the first 2 fractions)

= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] (the lowest common denominator of 3 and 5 is 15)

= (5 x 2) + (3 x 3) / 15

= (10) + (9) / 15

= 10 + 9 / 15

= [tex]\frac{19}{15}[/tex]  .

Now we should add [tex]\frac{9}{15}[/tex]  with the fraction of ounce she had left: [tex]\frac{2}{15}[/tex]

Therefore, we have  

= [tex]\frac{19}{15}[/tex] + [tex]\frac{2}{15}[/tex]  (the lowest denominator of 15 and 15 is 15)

= (19 x 1) + (1 x 2) / 15

= (19) + (2) / 15

= [tex]\frac{21}{15}[/tex]  .

Recall that the total paint is 2-ounce. Therefore, to get the fraction of ounce used to paint a flag, we have to subtract the ounce of the total paint from the [tex]\frac{21}{15}[/tex] .

Therefore we have:

2-[tex]\frac{21}{15}[/tex]  (can also be expressed as [tex]\frac{2}{1}[/tex] – [tex]\frac{21}{15}[/tex] )  

= (15 x 2) – (1 x 21) / 15 (the lowest denominator is 15)

= (30) – (21) / 15

= 30 – 21 / 15

= [tex]\frac{9}{15}[/tex]  or [tex]\frac{3}{15}[/tex]  .  

Therefore Shelby used [tex]\frac{9}{15}[/tex] or [tex]\frac{3}{5}[/tex] ounce to paint the flag.

Answer:

The answer is y=20

Step-by-step explanation:

If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.

Next, add angles B and C together to get 50.

Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.

Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)

Next, slove the equation.

And theres your answer, I hope I helped. Put any questions in the comments.

The value of y in the isosceles triangle is 20. This was determined by making use of the angles sum property of a triangle and the specific properties of an isosceles triangle.

The subject of this question is geometry, specifically the properties of an isosceles triangle and the inner angles. An isosceles triangle is a triangle with at least two equal sides - in this case, sides AB and AC. Because it is an isosceles triangle, angles B and C are equal. Therefore, we know that the value of angle C in degrees is also 25 (5x = 25).

According to the angles sum property of a triangle, the sum of the inner angles of a triangle is always 180 degrees. Therefore, we have the equality: (3y + 70) + 25 + 25 = 180. If we subtract 70 from both sides, we have 3y = 180 - 120, which simplifies to 3y = 60. To solve for y, we divide both sides by 3. Concluding, y = 60/3 = 20.

Step-by-step explanation:

Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.

This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.

The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.

Step-by-step explanation:

Temperature was [tex]0[/tex] degrees and it fell to [tex]-6\frac{3}{5}=-\frac{33}{5}[/tex] in [tex]2\frac{1}{5}=\frac{11}{5}[/tex] hours.

To get temperature change per hour, we divide the change by total number of hours. So:

So temperature changer per hour:

[tex]\frac{-\frac{33}{5}}{\frac{11}{5}}\\=-\frac{33}{5}*\frac{5}{11}\\=-\frac{33}{11}\\=-3[/tex] degrees per hour.

Answer:

The temperature change per hour was -3 degrees per hour.

Step-by-step explanation:

We know that the temperature fell from [tex]0[/tex] degrees to [tex]-6\frac{3}{5}[/tex] degrees in a time period of [tex]2\frac{1}{5}[/tex] hours.

So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.

For that, we will change the mixed number into improper fractions and then solve:

[tex]-6\frac{3}{5}=-\frac{33}{5}degrees[/tex]

[tex]2\frac{1}{5}=\frac{11}{5} hours[/tex]

Temperature change per hour = [tex]\frac{-\frac{33}{5}}{\frac{11}{5}} = \frac{33}{5}*-\frac{5}{11}=-3[/tex]

Therefore, the temperature change per hour was -3 degrees per hour.

Step-by-step explanation:

A coefficient is a number written with a variable to indicate the product of the number and the variable in a term.

In any of the algebraic expressions or an equation or a polynomial, a term contains at least one variable and a coefficient (numerical value). Thus, the coefficient of the term is one of the factors. So, the coefficient is indicated by the product of the number and the variable in a term.

The number written with a variable indicates the product of the number and the variable in a term is its coefficient. This is because it is a numerical value and it is the factor for the term.

E.g., 4xy - here 4 is the coefficient, and x y are the variables.
