Answer:

A translation simply moves the graph, or pre-image, without changing the size or spinning the image. A reflection flips the pre-image across some line. A rotation spins the pre-image around a point. A dilation either expands or shrinks the pre-image.

Answer:

A dilation is the only type of transformation that can change the size of a figure. A dilation results in similar figures, while other transformations result in congruent figures. It can still be described using a mapping and corresponding parts.

There are 3 feet in 1 yard. This is equivalent to 12 feet in 4 yards. Which proportion can be used to represent this?

Troyanec [42]

Proportion which can be used to represent equivalency of 3 feet in 1 yard and 12 feet in 4 yard is 3 : 1 : : 12 : 4

<h3><u>Solution:</u></h3>

Given that

There are 3 feet in one yard

And there are 12 feet in 4 yard

Number of feet in one yard = 3 that is feet : yard = 3 : 1

Number of feet in 4 yards = 12 that is feet : yard = 12 : 4

And 3 feet in 1 yard is equivalent to 12 feet in 4 yards means

$\frac{3}{1}=\frac{12}{4}$

That is 3 : 1 : : 12 : 4

A proportion is statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a : b = c : d

Hence proportion which can be used to represent equivalency of 3 feet in 1 yard and 12 feet in 4 yard is 3 : 1 :: 12 : 4

Richard bought 3 1/4 ft of plumbing pipe. The pipe cost $1.60 a foot. How much did Richard pay for plumbing pipe?

Vanyuwa [196]

2 1/8=2.125 and 3 3/8=3.375 then let x represent the amount of money that he payed for felt. Next 2.125+3.375=5.5 then
x=5.5*1.5
x=8.25
