Answer: $7

Step-by-step explanation:

Let x = Cost of each T-shirt.

As per given,

Total charge  =( Number of t shirts x Cost per t shirt )+ set up fee  

For 21 T-shirts , total charge would be : 21x+40  

According to the question

⇒21x+40=187

⇒21x = 187-40

⇒21x = 147

⇒x= 7

Hence, each T-shirt costs $7 .

Step-by-step explanation:

Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT

Since VR = length * width and height

VR = 6*x*3

VR = 18x ft³

Also VT =  Length *width * Height/2

VT = (7 * x * 4)/2

VT = 28x/2

VT = 14xft³

Since VR = 32 + VT

18x = 32+(14x)

collect like terms

18x-14x = 32

4x = 32

divide both sides by 4

4x/4 = 32/4

x = 8

Volume of the rectangular prism = 18x

Volume of the rectangular prism = 18*8

Volume of the rectangular prism = 144ft³

Volume of the right triangular prism = 14x

Volume of the rectangular prism = 14*8

Volume of the rectangular prism = 112ft³

Answer:

rectangular is 114ft and triangular is 112ft

Step-by-step explanation:

Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT

Since VR = length * width and height

VR = 6*x*3

VR = 18x ft³

Also VT =  Length *width * Height/2

VT = (7 * x * 4)/2

VT = 28x/2

VT = 14xft³

Since VR = 32 + VT

18x = 32+(14x)

collect like terms

18x-14x = 32

4x = 32

divide both sides by 4

4x/4 = 32/4

x = 8

Volume of the rectangular prism = 18x

Volume of the rectangular prism = 18*8

Volume of the rectangular prism = 144ft³

Volume of the right triangular prism = 14x

Volume of the rectangular prism = 14*8

Volume of the rectangular prism = 112ft³

The figures demonstrate a reflection are option (B) and option (D) are the correct answer.

A reflection is a type of transformation. It maps one shape onto another. The function retains its basic shape; however, by including a negative sign in the appropriate place in the equation, the graph of the function will flip over one or the other of the axes.

For the given situation,

The options shows the different figures. we need to select the figure that correctly demonstrates the reflection.

Option A:

Here, the figure is not flipped on the axes.

The figure in option A does not show the transformation of reflection.

Option B:

Here, the figure is flipped on the axes.

The figure in option B shows the transformation of reflection.

Option C:

Here, the figure is not flipped on the axes.

The figure in option C does not show the transformation of reflection.

Option D:

Here, the figure is flipped on the axes.

The figure in option D shows the transformation of reflection.

Hence we can conclude that the figures demonstrate a reflection are option (B) and option (D) are the correct answer.

y+6=15

Step-by-step explanation:

3+3+16+19+y=41+y

41+y/5=10

multiply both sides by 5

205+y/5=50

41+y=50

Rearrange the equation so y is isolated.

y= 50-41

Answer: I am doing this quiz right now I think the answer is C, 600.

Step-by-step explanation:

I think the higher you increase the sample size, the closer you get to the actual parameter.

The sizes that should be  closest to the actual parameter value of a population is option c. 600.

It represent the amount of the parameter that can be in the form of the mean or the standard deviation. Also, it helps for determining the confidence interval.

Also, we know that if the sample size is high so there should be more precise for the estimate.

Step-by-step explanation:

The given function is linear function.

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3[tex]x[/tex] - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with g([tex]x[/tex]), this function can be written as g([tex]x[/tex] )= 3[tex]x[/tex] - 2.

A linear function is of the form g([tex]x[/tex]) = m[tex]x[/tex] + b where 'm' and 'b' are real numbers. Here,

Answer: 45 / 40 ft

Step-by-step explanation:

Given that She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor?

Actual width of shorter side = 45 ft

New width of shorter side = 40 ft

Scale factor is the ratio of the actual length to the new or intended length

Scale factor = Actual width / New width

Hence, scale factor :

45 ft / 40 ft

Answer:

1.  You can prove that a line parallel to one side of a triangle divides the other 2 sides proportionally by using the Triangle Proportionality Theorem.  

2. You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.

28(5280)=147840 feet per hour.

There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.

147840/60=2464

And we divide by sixty again to get to seconds.

2464/60=41 1/15 feet per second.

Have a wonderful day! :D

Multiply to feet.

28 * 5280 = 147840

Divide by an hour in minutes.

147840 / 60 = 2464

Divide by a minute in seconds.

2464 / 60 = 41 1/5 ft/s

Step-by-step explanation:

You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.
