The shape with a rotational symmetry would remain the same when rotated
The shape with the smallest angle of rotational symmetry of 180 degrees is shape D
How to determine the shape?To do this, we simply examine each of the options
Shape A: Cross
The shape has 4 equal sides.
So, the smallest angle of rotational symmetry is:
Angle = 360/4
Angle = 90
The smallest angle of rotational symmetry is 90 degrees
Shape B: Star
The shape has 5 vertices.
So, the smallest angle of rotational symmetry is:
Angle = 360/5
Angle = 72
The smallest angle of rotational symmetry is 72 degrees
Shape C: Composite figure
This shape has a square and a triangle merged together at two ends
This means that the smallest angle of rotational symmetry is a complete rotation of 360 degrees
Shape D: Circle
The circle is divided into two equal segments.
The angle on the straight line of each segment is:
Angle = 360/2
Angle = 180
The smallest angle of rotational symmetry is 180 degrees
Hence, the shape with the smallest angle of rotational symmetry of 180 degrees is shape D

Let g(x) = 3x+ 2 and f(x) = x-2/ 3 Find the value.
f(g(0))
0
-2/3
1
-1
Explanation needed please!! I'm confused on how to solve.
Answer:
0** (READ BELOW)
Step-by-step explanation:
First, solve for g(0). Since g(0) = 3x +2, we plug in 0 for x.
So,
g(0) = 3(0) + 2 = 0 + 2 = 2.
Now that we have an answer for g(0), we can plug it into f(x).
So,
f(x) = (x-2)/3
f(x) = f(g(0)) = f(2).
f(2) = (2-2)/3 = 0/3 = 0.
Thus, f(g(0)) = 0.
Essentially, you first solve for g(0) and use the answer from that to solve for f(x) where x is your answer from g(0).
**I was unsure of what the equation was for f(x) based on how you wrote it in the question, but I assumed it was f(x) = (x-2)/3.
Find the surface area of this cube. Be sure to include the correct unit in your answer.
Answer: 54 inch²
Step-by-step explanation:
The total surface area of the cube can simply be found by finding the area of one face and multiplying by 6 because the cube has 6 faces
Area of one face = 3 inch x 3 inch = 9 inch²
Total surface area of the cube = 9 inch² x 6 = 54 inch²

Answer: 2.5$
Step-by-step explanation: Since 1 hour is half of 2 hours and the price to park for 2 hours is 5. We can take half of the 2 hour parking price to find the 1 hour price.
5$/2 Hours = 2.5$ per hour
Please help me i have part one to this question I told you guys everything you need to know in my last question Ill show u my last question in comments and also 100 POINTS PLEASE HELP AND ILL BRAINLEST
Answer:
See below ~
Step-by-step explanation:
1. Vertically opposite angles are equal when two lines intersect.
m∠3 = m∠12. The sum of two interior angles is equal to the exterior angle forming a linear pair with the third angle.
m∠4 = 88° because 180 - (41 + 47) = 92 and 180 - 92 = 883. The sum of the interior angles of a triangle is 180°.
55° + 90° (right angle) + ∠ACB = 180°∠ACB = 180° - 145°∠ACB = 35°4. You can find the length of a hypotenuse using the Pythagorean Theorem.

The diagram shows a cube with edges of length x cm and a sphere of radius 3cm
The surface area of circle of radius 3 cm and cube of edge length x cm being equal implies [tex]x = \sqrt{k\pi}[/tex] integer (k = 6).
How to find the surface area of a sphere?Suppose that radius of the considered sphere is of 'r' units.
Then, its surface area S would be:
[tex]S = 4\pi r^2 \: \rm unit^2[/tex]
Given that:
Side length of considered cube = x cmRadius of considered sphere = 3 cmSurface area of the considered cube = surface area of the considered sphere.Finding the surface area of the considered cube and sphere:
Surface area of cube with x cm edge length = [tex]\rm 6 \times side^2 = 6(x)^2 \: \rm cm^2[/tex]Surface area of sphere with radius r = k cm is [tex]4 \pi r^2 = 4\pi (3)^2 = 36\pi \: \rm cm^2[/tex]Thus, we get:
[tex]6x^2 = 36\pi\\\\\text{Dividing both the sides by 6}\\\\x^2 = 6\pi\\\\\text{Taking root of both the sides}\\\\x = \sqrt{6\pi} \: \rm cm[/tex]
(took positive value out of the root since x cannot be negative as it represents length of the edge of a cube which cannot be a negative quantity).
Thus, the surface area of circle of radius 3 cm and cube of edge length x cm being equal implies [tex]x = \sqrt{k\pi}[/tex] integer (k = 6).

You attend a working dinner with four other colleagues. Since alcohol
is not reimbursed by your company. your party receives two separate
bills: One for food ($156.65) and one for alcohol ($49.50). Each
needs to be split 5 ways.
How much do you owe for each bill?
$3.13 for food and $9.90 for alcohol
$31.33 for food and $0.99 for alcohol
$31.33 for food and $99.0 for alcohol
Using proportions, it is found that the amount owed for each bill are given as follows:
$31.33 for food $9.90 for alcohol.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, each of the bills are split equally among the five people, hence the fraction is 1/5.
Thus:
1/5 x 156.65 = $31.33
1/5 x 49.50 = $9.90.
Hence the amount owed for each bill are given as follows:
$31.33 for food $9.90 for alcohol.

Two friends, Bob and Ben, each buy one ticket for a drawing. They can choose six numbers from a total of one hundred numbers (0 - 99) for their ticket. Bob chooses the numbers 1, 2, 3, 4, 5, 6, and Ben chooses the numbers 39, 45, 66, 72, 74, 89. Who has a higher probability of winning the drawing?
Bob and Ben, both have equal probabilities of 6 % of winning.
What is probability?Given that Bob and Ben are two friends who buy one lottery ticket each. Each ticket contains six numbers from a total of one hundred numbers from 0 to 99.
Bob chooses the numbers 1, 2, 3, 4, 5, 6, and Ben chooses the numbers 39, 45, 66, 72, 74, 89.
We are to select the friend who has a higher probability of winning.
Let, 'S' be the sample space for the experiment.
Then, S = {0, 1, 2, . . . , 98, 99} ⇒ n(S) = 100.
Let, B and F are the events that Bob win and Ben win respectively.
Then,
B = {1, 2, 3, 4, 5, 6} ⇒ n(B) = 6
and
F = {39, 45, 66, 72, 74, 89} ⇒ n(F) = 6.
Therefore, the probability of even t B is
[tex]P(B)=\dfrac{n(B)}{n(S)}=\dfrac{6}{100}=6\%[/tex]
and the probability of event F is
[tex]P(B)=\dfrac{n(F)}{n(S)}=\dfrac{6}{100}=6\%[/tex]
Since, both the events have equal probabilities, so there is an equal chance of winning of Bob and Ben.

Meeko insurance offers an annuity with a minimum interest rate of 4% for the next five years. You decide to invest 1000 into his account. what type of annuity is this?
a.single-payment fixed annuity
b.recurring-payment fixed annuity
c. recurring-payment variable annuity
D.single-payment variable annuity
Answer:
single payment variable annuity
Step-by-step explanation:
Given : ABC Insurance offers an annuity with 4.5% APR for the next 5 years. You decide to invest $1000 each year into this account.
To find : What type of annuity is this?
Solution :
Annuity is the form of insurance in which some of the money is paid each year to secure for future.
There are two types of annuity:
Single payment variable annuity - In this annuity the payment is made at the end of each period over a fixed length of time. Also in this annuity payments are made monthly, quarterly, semi-annually or annually.
Annuity due - is the opposite of single payment variable annuity as in this the payment is made at the beginning of each period.
In the given situation the annuity is single payment variable annuity because the investment is done each year for 5 years.
