C. Image C: square

D. Image D: regular pentagon

E. Image E: regular hexagon

plz help me

Answers

Answer 1

Answer: B, C and E

Explanation

Answer 2

A figure with a rotation symmetry will look the same, when rotated. The figures with [tex]180^o[/tex] rotation symmetry are:

B: rectangle

C: square

E: regular hexagon

For a shape to have a [tex]180^o[/tex] rotation symmetry, the following must be true.

The shape must have an even number of sides (4,6...)The shape must have equal and parallel opposite sides.

Options (a) and (d) do not meet any of the above conditions.

However, the stated conditions are true for options (b), (c) and (e); because they have parallel & equal opposite sides; and they have an even number of sides.

Hence, the rectangle, the square and the regular hexagon have a [tex]180^o[/tex] rotation symmetry

See attachment for an illustration of rotation symmetry.

Eight year-old Alex is learning to ride a
horse. The trainer says that a horse
ages 5 years for every 2 human years.
The horse is now 50 years old in human
years. How can you determine the age
of the horse, in human years, when Alex
was born?
Hint: Use a table or a graph to
help you find the solution.
Show your work.

Answers

Answer:

The age of the horse, in human years, when Alex was born can be determined by simply deducting the Current age of Alex from the Current age of the horse in human years.

Therefore, the age of the horse, in human years, when Alex was born was 42 years.

Step-by-step explanation:

Current age of Alex = 8

Current age of the horse in human years = 50

Since the age of the horse is already stated in human years, it implies there is no need to convert the age of the horse again.

Therefore, since Alex is a human who was born 8 years ago, the age of the horse, in human years, when Alex was born can be determined by simply deducting the Current age of Alex from the Current age of the horse in human years as follows:

The age of the horse, in human years, when Alex was born = 50 - 8 = 42

Therefore, the age of the horse, in human years, when Alex was born was 42 years.

This can be presented in a table as follows:

Age of Alex Age of the Horse (in human years)

Eight years ago 0 42

Current age 8 50

Trevor is looking at purchasing a new cellular phone plan. Company A charges $35.25 a month, plus $.11/min for local calls. Company B charges $14.25 a month, plus $.32/min for local calls. Trevor stated that if he used x amount of minutes, the cost of the phone companies would be the same. For what amount of minutes, x, would Trevor's argument be true? Trevor is planning to use at least a 100 minutes for local a month. Which company would be cheaper for Trevor to use?

Answers

Answer: Trevor's argument will be true if he used 100 minutes.

Let x represent the amount of minutes that Trevor would use for the cost of the phone companies to be the same.

Company A charges $35.25 a month, plus $.11/min for local calls. This means that the total cost of making x minutes of call with Company A's plan is

32.25 + 0.11x

Company B charges $14.25 a month, plus $.32/min for local calls. This means that the total cost of making x minutes of call with Company B's plan is

14.25 + 0.32x

For both costs to be the same, the number of minutes would be

35.25 + 0.11x = 14.25 + 0.32x

0.32x - 0.11x = 35.25 - 14.25

0.21x = 21

x = 21/0.21 = 100

Answer:

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

Answer:

Step-by-step explanation:

Green bat: x

Purple bat: y

Pumpkin: z

Given:

2x + y = 40

y - z = 7 ===> y = 7 + z

z + x = 19 ===> z = 19 - x

Substitution to find green bat x:

2x + y = 40

2x + (7 + z) = 40

2x + 7 + z = 40

2x + 7 + (19 - x) = 40

2x + 7 + 19 - x = 40

x + 26 = 40

green bat: x = 14

Substitution to find pumpkin z:

z + x = 19

z + (14) = 19

z + 14 = 19

pumpkin: z = 5

Substitution to find purple bat y:

y - z = 7

y - (5) = 7

y - 5 = 7

purple bat: y = 12

Solve for x - z + y:

14 - 5 + 12 = 21
