In geometry, transformation involves changing the position and/or size of a shape.

<em>The transformation that will change the size of ABCD is dilation.</em>

There are four transformations in geometry:

  • Translation
  • Reflection
  • Rotation
  • Dilation

Of all types of transformation, dilation will change the size of the shape,

The new shape will either be enlarged or reduced

<em>Either ways, the size of the shape will be altered.</em>

<em>When the size is altered, the perimeter will not remain the same.</em>

<em />

Hence. dilation will change the perimeter of ABCD.

An angle measures 48.4° less than the measure of its complementary angle. What is the measure of each angle?
Gennadij [26K]

Answer:

The angles are 69.2 degrees and 20.8 degrees

Step-by-step explanation:

Complementary angles, when added together, = 90°

We’ll call the first unknown angle a and the second angle b

b = a - 48.4

a + b = 90

So let’s substitute in for b in the second equation:

a + a - 48.4 = 90

2a - 48.4 = 90

2a = 138.4

a = 69.2

69.2 - 48.4 = 20.8 = b

Now, does a + b = 90?

69.2 + 20.8 = 90

According to the Pew Internet &amp; American Life Project, 54% of Internet users have a wireless connection to the Internet via
Setler79 [48]

Answer: 0.135

Step-by-step explanation:

if 54 % of internet users have a wireless connection then number of people that do nor have a wireless connection =46%.

Let A be the event that 54% of internet users have wireless connection.

Let B be the event that 25% of these users that have internet connection use twitter to share updates about themselves.

Hence, probability of A and B happening becomes:

P(AnB) = P(A) * P(B)

P(AnB) = 0.54 * 0.25

P(AnB) = 0.135

Molly owes her brother $300.She works for $10 per hour as a checker at the local grocery store.Molly plans to repay her brother
gavmur [86]

Answer: The expression which represents the condition described is given as  4x=300

Step-by-step explanation:

Since we have given that

Amount that Molly owes her brother = $300

Let the number of hours she worked as a checker be x

Cost of per hour = $10

Amount she get after doing work for x hours is given by

10x

Rate of tax are taken out = 80%

So, amount she left with is given by

\frac{100-20}{100}\times 10x\\\\=\frac{80}{100}\times 10x\\\\=8x

So, Molly plans to repay her brother half of what she earns is given by

\frac{8x}{2}=4x

According to question,

4x=300\\\\x=\frac{300}{4}\\\\x=75\ hours

So, the expression which represents the condition described is given as

4x=300
