A regular pentagon is centered about the origin. Which transformation
maps the pentagon onto itself?
a. A reflection across line m
b. A reflection across the x-axis
C.
d.
A clockwise rotation of 144 degrees about the origin
Answers
Answer:
The answer is D. A clockwise rotation of 144 degrees about the origin.
Step-by-step explanation:
In most cases; when an object is transformed, the position of the object changes. A clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.
Given:
The attached pentagon
The number of sides (n) in a pentagon is:
[tex]n = 5[/tex]
The pentagon will not be mapped onto itself when reflected across line m because m is not at the center of the polygon
The pentagon will not be mapped onto itself when reflected across the x-axis because the pentagon has 5 sides (odd number of sides)
To map the pentagon onto itself, the pentagon has to be rotated.
The angle of rotation is:
[tex]\theta = \frac{360}n[/tex]
[tex]\theta = \frac{360}5[/tex]
[tex]\theta = 72[/tex]
Other possible angles of rotation must be a multiple of 72. i.e.
[tex]\theta = 72, 144, 216, 288....[/tex]
This means that: option (d) is correct because 144 is a multiple of 72
Hence, a clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.

What is the greatest number of bags you can fill using all the candy?
How many chocolate bars will be in each bag?
How many peanut butter cups will be in each bag?
Answers
Answer:
If you can't split up the peanut butter cups, the identical bags would each have 1 chocolate bar and 1 peanut butter cup because 30 cannot be divided between 18 bags as whole numbers more than once.6Is you're looking for the answer all you have to do is find the gcf (greatest common factor) of 18 and 30 and you would get 6I hope this helpsAnswer:

When Stacey’s son,Kevin, solves the problem,he changed the equation from part C to one that didn’t have any fractions. In other words, he eliminated the denominator on both sides of the equation.Explain how to get rid of both denominators in the equation 9/2=x/24
Answers
Answer:
To get rid of the 2 in the denominator of 9/2 multiply both sides of the equation by 2 or 2/1. to get rid of the 24 in the denominator of x/24, multiply both sides the equation by 24 or 24/1

Nicole is making smoothies. She uses 1.2 kilograms of apples and 600 grams of strawberries. How many kilograms of fruit does Ann use in all?
Answers
Answer:
wait Ann? wasn't the question stating that Nicole was making smoothies? kinda threw me off
either way: 1.8 kilograms of fruit
Step-by-step explanation:
first you need to convert all of your measurements into a same unit, so 600 grams into kilograms, remember that 1 gram = 0.001 kilograms, so all you need to do is multiply 600 by 0.001
you'll get 0.6 and then you add that to 1.2 kilograms which is 1.8 in total. hope it helped

A 3 ft tree casts a 10 ft. shadow. How many feet long is the shadow of a 26 ft tall tree at the same time? If necessary, round to the nearest tenth.
Answers
Answer:
8 feet
Step-by-step explanation:
It is given that, a 3 ft tree casts a 10 ft. shadow. It means that 1 ft long shadow will cast by [tex]\dfrac{3}{10}[/tex] feet long tree.
Let 26 ft tall tree will cast x feet long shadow. To find it using unitary method we get :
[tex]x=\dfrac{3}{10}\times 26\\\\x=7.8\ \text{feet}[/tex]
or
x = 8 feet
So, 8 feet long is the shadow of a 26 feet tall tree.
