Answer:
B) A dilation followed by a reflection
3 of our transformations are called isometries. These are transformations that preserve the size and shape of the original figure; they just change the position or orientation of it. Translations, reflections and rotations are all isometries. We know that isometries preserve congruence, since they maintain the size and shape of the original figure.
dilation changes the size of a figure. Since the new figure will not be the same size as the original, they will not be congruent.

Answer:
Step-by-step explanation:The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm. The area A of a rectangle with length l and width w is A=lw .
Answer:
8
Step-by-step explanation:
mean of A=28+23+30+25+27/5 = 26.6
average of B=22+19+15+17+20/5 = 18.6
now,
difference= 26.6-18.6

Answer:
13 miles
Step-by-step explanation:
3 1/4 can be changed to 3.25
Then multiply 3.25 (the time) and 4 (the distance per hour) to get 13.
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
