Answer is A. PQRST = XWVZY

Explanation- the 2nd figure was transformed with a reflection and a rotation

We know the congruent vertices will match exactly in how they are sequenced in order

First I located the same vertices of S and Z

Second I noticed the 2nd figure was reflected so I rearranged the sequence of vertices to match the reflection

Problem solved!

The ratio of the perimeters of two rectangles is 4 to 7. The perimeter of the larger rectangle is 42 inches. What is the perimet

Mumz [18]

In this question, there are numerous information's of immense important already given. Based on those given information's the answer to the question can be easily deduced.
Ratio of the perimeter of two rectangles = 4:7
Perimeter of the larger rectangle = 42 inches
Let us assume the common ratio = x
Then
7x = 42
x = 42/7
= 6
Then
Perimeter of the smaller rectangle = 4 * 6 inches
= 24 inches.
So the perimeter of the smaller rectangle is 24 inches. I hope the procedure and the answer is clear enough for you to understand. Based on this procedure, you can attempt similar problems without requiring any outside help.

A candle holder is in the shape of a triangular pyramid. The area of the base is 15 in2

EleoNora [17]

The volume of candle holder is 30 inches cubed.

Step-by-step explanation:

Given,

Area of base = A = 15 square inches

Height of candle holder = H = 6 inches

As the holder is in shape of triangular pyramid, therefore,

Volume of candle holder = $\frac{1}{3}AH$
