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
D- 1 mile
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.

a box in the shapr of s rectangular prism has a length of 3 5/8 inches, a width of 2 1/2 inches and a height of 4 inches. what is tje volume of the box?
Answer:
V = 36 1/4 in.^3
Step-by-step explanation:
V = LWH
L = 3 5/8 in.
W = 2 1/2 in.
H = 4 in.
V = (3 5/8)(2 1/2)(4) in.^3
Change the mixed numerals to fractions.
To change the mixed numeral a b/c to a fraction, do this:
a b/c = (ac + b)/c
V = (3 * 8 + 5)/8 * (2 * 2 + 1)/2 * 4/1
V = (24 + 5)/8 * (4 + 1)/2 * 4/1
V = 29/8 * 5/2 * 4/1 in.^3
V = 580/16 in.^3
V = 145/4 in.^3
V = 36 1/4 in.^3

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.

Write two polynomial functions whose quotient will be the same degree as the divisor?
Answer:
[tex]f(x) = 15x^2 -14x - 8[/tex]
[tex]g(x) = 5x + 2[/tex]
Step-by-step explanation:
Represent the two polynomials with f(x) and g(x)
The question requires that we assume values for f(x) and g(x) as long as the condition in the question is met;
Let
[tex]f(x) = 15x^2 -14x - 8[/tex]
[tex]g(x) = 5x + 2[/tex]
To determine if the condition is met, we need to divide f(x) by g(x)
[tex]\frac{f(x)}{g(x)} = \frac{15x^2 -14x - 8}{5x + 2}[/tex]
Factorize the numerator
[tex]\frac{f(x)}{g(x)} = \frac{15x^2 - 20x + 6x - 8}{5x + 2}[/tex]
[tex]\frac{f(x)}{g(x)} = \frac{(5x + 2)(3x - 4)}{5x + 2}[/tex]
Cross out 5x + 2
[tex]\frac{f(x)}{g(x)} = 3x - 4[/tex]

3. Miguel and his family are on vacation and notice an advertisement for a taxi service
that charges a fee of $12 to pick up a family and an additional fee of $0.55 per mile for
the trip. Write an equation that models this situation, using m to represent the number
of miles traveled and t to represent the total cost for the trip. Find the total cost of an
18 mile trip.
Student's Work
Student's Answer
A. t = 0.55m + 12; $21.90
B. t = 12m +0.55; $21.90
C. t = 0.55 + m + 12 $30.55
D. t = 0.55(12) + m; $24.60
Answer: The answer would be A : t=0.55m+12;$21.90
The equation that models the situation, using m to represent the number of miles traveled and t to represent the total cost for the trip is A. t = 0.55m + 12; and the total cost of an 18 mile trip is $21.90.
⇒ The correct answer is A. t = 0.55m + 12; $21.90
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Cost of pick up = $12
Additional fee = $0.55 per mile
Now if,m represent the number of miles traveled and t to represent the total cost for the trip
Thus, Total additional fee = 0.55m
⇒ Total cost for the trip = Total additional fee + Cost of pick up
⇒ t = 12 + 0.55m
This is the equation that models the situation.
Now the total cost of an 18 mile trip, put m = 18 in the equation we get,
⇒ t = 12 + 0.55*18
⇒ t = 12 + 9.9
⇒ t = 21.9
Thus,the total cost of an 18 mile trip is $21.90.
The equation that models the situation, using m to represent the number of miles traveled and t to represent the total cost for the trip is A. t = 0.55m + 12; and the total cost of an 18 mile trip is $21.90.
Thus the correct answer is A. t = 0.55m + 12; $21.90

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.

First off, vertical angles are always congruent. Which means <A will be equal to <B.
m<A=8x+14
m<B=2x+50
8x+14=2x+50
So you want to get x alone so subtract 2x from each side.
6x+14=50
Since the variable is not alone you will also need to subtract 14 from both sides.
6x=36
You will need to divide both sides by 6
x=6
You now have x. You need angle B though so your not finished.
Plug 6 in for x.
