Mrs.Gunn makes one costume in 3hours and 20 minutes. How long will it take her to make 6 costumes for a school play?

Answer

you put an open circle on -2 on the number line and continue the line into negative infinity ( the left side of the number line)

Step-by-step explanation:

The slope formula for the line that passes through the points (3, 7) and (5, 7) is (7-7)/ (5-3).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have points (3, 7) and (5, 7).

So, the slope of line passes through the given points

= ( 7 - 7) / (5-3)

= 0- 2

= 0

Thus, the slope formula is (7-7)/ (5-3).

The correct expression for the slope between points (3, 7) and (5, 7) is D) 7 - 7/ 5 - 3, which equals 0, indicating a horizontal line.

To find the slope of a line passing through the points (3, 7) and (5, 7), we use the slope formula m = (y2 - y1) / (x2 - x1).

For the points (3, 7) and (5, 7), the correct way to set up the slope formula is: (7 - 7) / (5 - 3).

This simplifies to m = 0 / 2, which equals 0.

Therefore, the correct expression that shows the slope for the line that passes through the points (3, 7) and (5, 7) is D) 7 - 7/ 5 - 3.

The equation used to find the cost of student ticket is:

[tex]13x + 3.50 + 3x + 18.50 = 50[/tex]

Solution:

Given that,

A teacher brings $50 to pay for museum  admission

She buys an adult ticket for $3.50 and 13 student tickets

Cost of adult ticket = $ 3.50

Let "x" be the cost of each student ticket

Three students arrive late  so she buys 3 more student tickets

She has $18.50 left

The equation used to find the cost of student ticket is:

Cost of adult ticket + 13 student tickets x cost of each student ticket + 3 student ticket x cost of each student ticket = 50 - 18.50

[tex]3.50 + 13x + 3x = 50-18.50\\\\13x + 3.50 + 3x + 18.50 = 50[/tex]

Thus the above equation is used

Answer:

So the line that is a perpendicular bisector of AB is [tex]y=\frac{3}{8}x+\frac{11}{16}[/tex].

Step-by-step explanation:

If we are looking for a line such that is is perpendicular bisector of AB, then we first need to find the midpoint of AB.

The midpoint of AB is going to be the "average" point.  

What I mean by this, to find the x-coordinate of the midpoint we need to average our x-coordinates of our endpoints and we also need to do the same for the y-coordinate part.

Let's begin this.

The average of the x-coordinates of the endpoints are:

[tex]\frac{2+5}{2}=\frac{7}{2}[/tex]

The average of the y-coordinates of the endpoints are:

[tex]\frac{6+(-2)}{2}=\frac{4}{2}=2[/tex]

This concludes the midpoint of AB is [tex](\frac{7}{2},2)[/tex].

Now we also need to calculate the slope of [tex]AB[/tex] so we can find the slope of the line perpendicular to it.

To do this we could use [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Without using the formula directly, I like to line the points up vertically and subtract. I then put the 2nd difference over the first difference. Like so,

  [tex](5,-2)[/tex]

-[tex](2,6)[/tex]

----------------------

[tex]3 , -8[/tex]

So the slope is [tex]\frac{-8}{3}[/tex].

The line that is perpendicular to the line AB will have an opposite reciprocal slope.

So the line we are looking for has slope [tex]\frac{3}{8}[/tex].

So we are looking for a line going through the midpoint [tex](\frac{7}{2},2)[/tex] and has slope [tex]\frac{3}{8}[/tex].

A line in slope-intercept form is [tex]y=mx+b[/tex].

We know [tex]m=\frac{3}{8}{/tex] and we know a point [tex](x,y)=(\frac{7}{2},2)[/tex]. We could plug this in to find [tex]b[/tex].

Let's do that now.

[tex]2=\frac{3}{8}(\frac{7}{2})+b[/tex]

Simplify:

[tex]2=\frac{21}{16}+b[/tex]

Subtract 21/16 on both sides:

[tex]2-\frac{21}{16}=b[/tex]

Find a common denominator:

[tex]\frac{32}{16}-\frac{21}{16}[/tex]

[tex]\frac{11}{16}[/tex]

So the line that is a perpendicular bisector of AB is [tex]y=\frac{3}{8}x+\frac{11}{16}[/tex].  This is so because the line we found will be perpendicular to AB while also cutting AB into two equal halves.

[tex]\boxed{y=-1}[/tex]

In order to solve this problem, let's remember the point-slope form of the equation of a line:

Answer:

4.5

Step-by-step explanation:

The equation above is such that we find the value of p. Therefore, it is calculated thus:

0.5p - 3.45 = -1.2

Add 3.45 to both sides of the equation

0.5p - 3.45 + 3.45 = -1.2 + 3.45

0.5p = 2.25

Divide both sides by 0.5

0.5p/ 0.5 = 2.25/0.5

p = 4.5

Answer: The answer is 4.5

Step-by-step explanation:

0.5p - 3.45 = -1.2

So basically, you take everything on the left of the equal sign (0.5p-3.45) then since the sign is telling you to subtract, you use the inverse operation, so you would add 0.5 to the 3.45 and to the -1.2. So when you add the 0.5 to the 3.45, it cancels out, and when you add it to the -1.2, you should get 2.25. Then now that your done adding, your expression should be: 0.5p = 2.25. Then, now that you have 0.5p = 2.25, and there is no sign, multiplication is expected, but since were using the inverse operation, were dividing. So, 0.5p divided by 0.5 cancels out, and then you divide the 2.25 by 0.5 and you should get 4.5 after dividing. So, your final answer should be p = 4.5.

the difference between a data value in a set and the mean of the set. the mean of all deviations in a set equals zero. absolute value. the distance of any value on a number line from zero. the sum of the absolute values of deviations on each side of the mean are equal.

Step-by-step explanation:

A data set that has a mean absolute deviation of 0 means the average difference between  the elements in a data set and mean of the same data set is very less.

The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

As we know the mean absolute deviation is the average distance between each data point and the mean.

If more than 50% of your data have identical values, your MAD will equal zero.

Also, the mean absolute deviation of a dataset is the average distance between each data point and the mean.

If the mean absolute deviation (MAD) is close to 0,it means the average difference between the elements in a data set and mean of the same data set is very less.

Thus,  the average difference between  the elements in a data set and mean of the same data set is very less.

Each animal require 3 balloons.

Step-by-step explanation:

Let 'x' be the number of balloon poodles.

Let 'y' be the number of balloon giraffes.

Multiply eqn (1) by 2 and subtract eqn(2) from eqn(1),

   4x+4y = 24

(-) 4x+5y = 27

      -y = -3  

⇒ y=3

⇒ Number of balloon giraffes = 3

Substitute y=3 in eqn(1)

⇒ 2x+6=12

⇒ x = 6/2

⇒ x = 3

⇒ Number of balloon poodles = 3

Answer:

The correct option is b.) $2.28

Step-by-step explanation:

i) the gas tank is of 15 gallons

ii) there are three gallons left in the gas tank

iii) therefore the tank has to be filled with 15 - 3 = 12 gallons

iv) lower grade of gasoline costs $2.96 per gallon

v) the upper grade of gasoline costs $3.15 per gallon

vi) the cost of filling the tank with the lower grade gasoline

   = 12 [tex]\times[/tex] 2.96 = $35.52.

vii) the cost of filling the tank with the lower grade gasoline

    = 12 [tex]\times[/tex] 3.15 = $37.80

viii) therefore  the difference in the cost of filling your tank between the two grades

  = $37.80 - $35.52 = $2.28

Therefore the correct option is b.) $2.28

Final answer:

The difference in the cost of filling the 15-gallon gas tank between the two grades of gasoline is $2.28.

Explanation:

Firstly, let's calculate how many gallons are needed to fill the car's tank completely, since it currently has 3 gallons left in a 15-gallon tank. This means the car requires 15 - 3 = 12 gallons of gasoline to be filled up.

Next, we calculate the cost to fill up the car with the lower grade gasoline that costs $2.96 per gallon. The cost for 12 gallons would be 12 x $2.96 = $35.52.

Then, we calculate the cost to fill up the car with the premium gasoline that costs $3.15 per gallon. The cost for 12 gallons would be 12 x $3.15 = $37.80.

Finally, to find the difference in cost between the two grades of gasoline, we subtract the lower cost from the higher cost: $37.80 - $35.52 = $2.28. Hence, the difference in cost is $2.28, so the correct answer is option (b).

Answer: [tex]C)62\°[/tex]

Step-by-step explanation:

For this exercise it is necessary to remember the definition of "Vertical angles".

Vertical angles are defined as those angles that are opposite to each other and share the same vertex. These angles are congruent, which means that they have equal measure.

You can identify in the picture that [tex]\angle XQL[/tex] and [tex]\angle MQR[/tex] are Vertical angles, then they are congruent.

Based on the above, you can set up the following equation:

[tex]-5b+82=-3b+74[/tex]

Now you must solve for "b" in order to find its value:

[tex]82-74=-3b+5b\\\\8=2b\\\\\frac{8}{2}=b\\\\b=4[/tex]

Finally, substituting the value of "b" into [tex]\angle XQL=-5b+82[/tex] and evaluating, you get:

[tex]\angle XQL=-5(4)+82\\\\\angle XQL=62\°[/tex]

Step-by-step explanation:

3x + 19 = 5x + 33

x = -7

y= 3x ( - 7) + 19

y= -2

(x, y) = (-7,-2)

The x and y value is -7 and -2.

Given that,

Based on the above information, the calculation is as follows:

3x + 19 = 5x + 33

3x - 5x = 33 - 19

-2x = 14

x = -7

Now put the value of x in any of the above equation

So,

y = 3x + 19

= 3(-7) + 19

= -21 + 19

= -2

Therefore we can conclude that the x and y value is -7 and -2.

The solution to the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method is x = -44/19 and y = -29/19.

To solve the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method, we need to multiply the equations by respective constants so that a variable gets eliminated when we add or subtract them. Let's try to eliminate y.

Multiply the first equation by 5 (the coefficient of y in the second equation) and the second equation by 2 (the coefficient of y in the first equation):

5*(3x+2y) = 5*(-10)

2*(2x-5y) = 2*3

15x + 10y = -50

4x - 10y = 6

Add the two equations:

(15x + 10y) + (4x - 10y) = -50 + 6
19x = -44

Divide both sides by 19 to solve for x:

x = -44/19

x = -44/19

Now substitute x back into one of the original equations to solve for y:

3x + 2y = -10

3*(-44/19) + 2y = -10

Multiply 3 by -44/19:

-132/19 + 2y = -10

Now solve for y:

2y = -10 + 132/19

2y = (-190/19) + (132/19)

2y = -58/19

Divide by 2:

y = -58/38

y = -29/19

Therefore, the solution to the system of equations is x = -44/19 and y = -29/19.
