Monica is making a design for art class she is experimenting with how to transform line segment AB in her design

Answers

Answer:

it will be A. Line segment AB and its image will be the same length and in different positions.

Step-by-step explanation:

hope this helps

Answer:

A reflection does not change lengths, so answers B and D are not right.

In most cases, a reflection will change the position of any object; so answer A would be right.

However, if segment AB is contained inline l, its reflection in line l will be in the same position.

Or if line l is the perpendicular bisector of segment AB, then the reflection of segment AB inline l will be in the same position as segment AB, but with the two endpoints, A and B switched.

So, with the question as posed and no further information about the relationship of line l and segment AB, the best answer is A; but in certain cases answer, C could be right.

Answers

Answer:

Step-by-step explanation:

This is the information we know :

A. a = 4

B. b = 15

C. c = 16

a + c

The a and c represent variables that must be substituted by their value, since we know their initial value, we substitute :

a + c when a = 4 and c = 16

4 + 16

The answer is 20 because a=4 and c=16 then 4+16=20

Which of these expressions is equivalent to 1/4x − 16 ?

Answer:

Perimeter: 18 ft

Height: 7 ft

Base Area: 12

Surface Area: (7)*(8) + 2(47) = 150

Step-by-step explanation:

To find the perimeter add all the edges together.

5 + 5 + 8 = 18

To find the height look at the diagram. 7ft shows the height of the rectangle and thus is the height for the rest of the shape.

Base Area:

Multiply the length (8ft) of the base by the height of the base (3ft)

8 * 3 = 24

Then divide by 2 to get the total area of the triangle

24 / 2 = 12.

Surface Area:

To find the surface area you to need to find the specifics of each side.

The base area we already solved for which is 12. We'll get back to this in a minute. The other double sides are of 5 * 7. That equals 35. Add together 12 + 35 to get 47. That is what will go in the 2(___) box because both of those sides have 2. It is the same number when done this way versus just adding them up.

47 * 2 = 94

12 + 12 + 35 + 35 = 94

Then for the (___)(___) that would be 7ft * 8ft because it is the only side left and does not have a double so it must be separate.

7 * 8 = 56

56+94 = 150

A doctor replaces the fish tank in her office. Do the fish have more room to swim in the new tank? Find the volume of each tank to find out.

The volume of the old fish tank, in cubic feet:

Answers

Answer: The volume of the old fish tank is 10 ft. The volume of the new fish tank is 8 ft.

Step-by-step explanation: The formula for a rectangle is A=l*w. Multiply the length and the width of the tank. 4*2 1/2 = 10. And 4*2 = 8. So the old fish tank is bigger than the new one.
