Answer:

Step-by-step explanation:
Given ∠2 and ∠4 are vertical angles.
Prove ∠2 ≅ ∠4
A proof is a set of logical statements that show that a statement is rational and true. See the proof for the above statement below.
What is the proof that ∠2 ≅ ∠4?Given ∠2 and ∠3 make a linear pair hence,
∠2 + ∠3 = 180
∠3 = 180 - ∠2....................1
Again ∠3 and ∠ translate to a linear pair. Hence
∠ 3 + ∠4 = 180, thus
∠3 = 180 - ∠4 .........................2
Drawing from 1 and 2, we get
180 - ∠2 = 180 -∠4 [Remove 180 from both sides]
⇒ -∠2 = -∠4
or ∠2 = ∠4
Thus, we have proven that ∠ and ∠4 are congruent angles.

Tara bakes 225 cookies in 5 hours, and she uses 8 pounds of sugar. She divides 225 by 5 to get a rate of 45. Which of the following corresponds to this rate?
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie
Answer:
c
Step-by-step explanation: Cookies per hour because if you divide the amount of cookies by the time it took to make them what your gonna get out of it is the amount of cookies baked per hour.
The rate 45 corresponds to cookies per hour.
What is Rate?Rate is defined as the ratio of two different quantities with different units. Ratio of two different quantities with the denominator equals 1 is called unit rate.
Unit rate, on the other hand can be defined as the amount of one quantity in a single unit of the other quantity.
For example, speed is the unit rate of distance and time.
Number of cookies Tara bakes in 5 hours is given as 225.
When 225 is divided by 5 to get a rate of 45, we are actually dividing the number of cookies with time to get how many cookies can be made in 1 hour.
So a rate of 45 implies that 45 cookies are baked by Tara in a single hour, which is the unit rate.
This means that this rate means cookies per hour.
Hence, the rate 45 corresponds to cookies per hour.

please please help me i can’t figure this out .. ernest's friend rolls a six-sided number cube and lands on square 8. She asks Ernest to guess what number she rolled. He guesses that she rolled a 3. She says he's wrong.
ernest wonders if she could have rolled a number other than 3. Use a mapping diagram to help guess what number she rolled.
If she would have rolled
Create a Mapping Diagram
When playing this game, the square you land on during the first turn depends on the number you roll. You can write this as a function: SQUARE(number), or S(n). For example, if you roll a 2, you end up on square 2 (when you land on 3 you move back a space). So S(2) = 2.
1. Describe the possible inputs of S(n) using words. (2 points: 1 point for the description, 1 point for the list of numbers)
2. Describe the possible outputs of S(n) using words. (1 point)
3. Draw a mapping diagram for S(n) that maps all the possible inputs and outputs for a player's first turn. Note that the player should begin on square 1. (6 points: 3 points for the inputs and outputs, and 3 points for the mapping)
4. In the mapping diagram you created, what numbers are in the domain of S(n)? Explain what this means. (2 points: 1 point for the domain, 1 point for the explanation)
5. What numbers are in the range of S(n)? Explain what this means. (2 points: 1 point for the range, 1 point for the explanation)
Evaluate the Conjecture
6. Based on the mapping diagram, is it possible that the player rolled a number other than 3 to land on square 8? If so, which number or numbers? Explain your answer. (2 points: 1 point for the answer, and 1 point for the explanation)
Defining Functions
7. Does the mapping diagram you created for S(n) for the first turn of the game represent a function? Why or why not? (2 points: 1 point for the answer, and 1 point for the explanation)
Answer:
1. The values of the dice. It can be 1,2,3,4,5,6.
2. Values in which you don’t move on the map. 2,5,6,11,14,15
3. inputs: 1,2,3,4,5,6
outputs: 2,2,8,5,6,8
4. Domain numbers are 1,2,3,4,5,6.
5. Range numbers are 2,2,8,5,6,8.
6.) The player could have rolled a 3 or a 6. Based on the chart, if they rolled a three they could land on a 8 and if they rolled a 6 they would have to move up a space.
7. The mapping diagram does represent a function because it tells how the numbers depend on each other.

The diagram is a straightedge and compass construction. A is the center of one circle, and B is the center of the other.
Explain why segments AC, CB, BD, and AD are all the same length.
All the segments AC, CB, BD, and AD are same in length because all are radiuses of the circles which have same dimensions.
What is a radius?Radius is the distance between circle center point and the point at its circumference.
In the given problem,
AC and AD are clearly the radiuses of the circle whose center is at point A (say first circle). Therefore these must be equal in length.
AC = AD
Similarly, BC and BD are the radiuses of the circle whose center is at point B (say second circle) . Therefore these are also equal in length.
BC = BD
Now you can observe that the first circle has a radius AB also which is equal to the radius of second circle i.e., BA.
∴ Both the circles has same radius length.
and
∴AC = AD = CB = BD
Hence all the segments which are nothing but the radiuses of both the circles must be equal.

Mrs. Moore walks 3 miles in one hour. How far does mrs.moore walk in 20 minutes?
A- 3 miles
B- 45 miles
C- 18 miles

Answer: D - 1 mile
Step-by-step explanation:
she walks 3 miles per hour -- one hour is equal to 60 minutes, and there are three 20s in 60. one mile per 20 = 60 (because 20*3=60) and so in 20 minutes she could walk 1 mile.

The formula P=c+m can be used to determine price P of an
item that costs c cents and a markup of m cents. The markup on a
can of juice is 25 cents. What is an equivalent version of this
Formula solved for c?
Answer:
c = P-25Step-by-step explanation:
Given the formula P = c+m which is used to determine price P of an item that costs c cents and a markup of m cents. To get the value of c, we will make c the subject of the formula;
P = c+m
subtract m from both sides
P-m = c+m-m
P-m = c
c = P-m
Given the price of mark up on a can of juice to be 25 cents, we will substitute m = 25 into the resulting expression as shown;
c = P-25
Hence the equivalent version of this formula solved for c is c = P-25

Answer:
[tex]z=\frac{at-67}{45+a}[/tex]
Step-by-step explanation:
Step 1: Write out equation
a(t + z) = 45z + 67
Step 2: Distribute a
at + az = 45z + 67
Step 3: Subtract 67 on both sides
at + az - 67 = 45z
Step 4: Subtract az on both sides
at - 67 = 45z + az
Step 5: Factor out z
at - 67 = z(45 + a)
Step 6: Divide both sides by 45 + a
[tex]z=\frac{at-67}{45+a}[/tex]
Answer:
Step 1: Write out equation
a(t + z) = 45z + 67
Step 2: Distribute a
at + az = 45z + 67
Step 3: Subtract 67 on both sides
at + az - 67 = 45z
Step 4: Subtract az on both sides
at - 67 = 45z + az
Step 5: Factor out z
at - 67 = z(45 + a)
Step 6: Divide both sides by 45 + a
