The length of the side between the vertices A′ and B′ is 16/7 units.

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> reflection, translation, rotation and dilation.</em>

Dilation is the increase or decrease in the size of a figure by a factor k. If a figure is dilated to produce an image, they are similar, hence the ratio of the corresponding sides are proportional.

$\frac{A'B'}{AB} =\frac{C'D'}{CD} \\
\\
\frac{A'B'}{4}=\frac{8}{14} \\
\\
A'B'=\frac{16}{7}$

The length of the side between the vertices A′ and B′ is 16/7 units.

If i sold 3 small boxes of oranges and 14 large boxes of oranges for total of $183. how much are the small and large box

Liono4ka [1.6K]

X = small boxes and y = large boxes

x + y = 17.....x = 17 - y
3x + 14y = 183

3(17 - y) + 14y = 183
51 - 3y + 14y = 183
-3y + 14y = 183 - 51
11y = 132
y = 132/11
y = 12 <=== large boxes (y) cost $ 12

x + y = 17
x + 12 = 17
x = 17 - 12
x = 5 <=== small boxes (x) cost $ 5

What is 7 2/10 as a decimal

Dmitry_Shevchenko [17]

When changing fractions into decimals the whole number goes before the period and the fraction goes after.The denominator of the fraction will tell you whether or not you need to put any zeros before the numerator. If the denominator is 10 zeros are not needed.The end result is 7.2 and can be read as seven tenths.

A watch seller gained 20% by selling a watch for rupees 1260. what was its cost price and if we add gain 30% at what price shoul

vekshin1

Answer:

1365 rupees

Step-by-step explanation:

1. Approach

The easiest method to solve this problem is via the method of proportions. One can use a proportion to find the original price of the watch. Then one can find the price of the watch if the watch had a (30%) mark up, by using a proportion.

2. Find the original price

Remember, the general format of a proportion is the following:

$\frac{part}{total}=\frac{percent}{100}$

The following information is given:

The watch sold for (1260) rupees which is (120%) of the original price. Remember, there was a (20%) gain, meaning that the seller recovered (120%) of the price, in essence, the price of the watch, plus (20%) extra, thus (120%). Substitute these values into the proportion and solve,

$\frac{part}{total}=\frac{percent}{100}$

$\frac{1260}{total}=\frac{120}{100}$

Simplify,

$\frac{1260}{total}=\frac{120}{100}$

$\frac{1260}{total}=\frac{6}{5}$

Cross product,

$\frac{1260}{total}=\frac{6}{5}$

$(5)(1260)=(6)(total)$

Simplify,

$(5)(1260)=(6)(total)$

$6300=6*total$

Inverse operations,

$6300=6*total$

$1050=total$

3. Find the price if the mark up is (30%)

Now, one knows the original price of the watch. Set up a proportion to find the price of the watch if there is a (30%) mark up. Use the same logic to set up this proportion as was used to set up the last one. The (percent) will be (130%) because the new price of the watch is (130%) of the original watch.

$\frac{part}{total}=\frac{percent}{100}$

Substitute,

$\frac{part}{total}=\frac{percent}{100}$

$\frac{part}{1050}=\frac{130}{100}$
