Answer: 13 miles per hour
Step-by-step explanation: 52 divided by 4 to find unit rate
The speed of bike which covers 52 miles in 4 hours is 13 miles per hour.
What is speed?In unit time the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The distance covered by bike in 4 hours = 52 miles.
To find the speed of the bike,
Use formula
Speed = distance / time
Since, distance is 52 miles and time is 4 hours,
Therefore, speed = 52 / 4 = 13 miles per hour
The required speed of bike is 13 miles per hour.

Is 92% on a math exam an A+ or an A?
It depends but it's most like a A.
I'd say a 98/99% is an A+
Answer:
A 92% on any exam would just be an A, because it's closer to a 90% than an 100%.
Step-by-step explanation:
If it's a 95% or higher, then you can consider that an A+.

What is the equation, in slope-intercept form, that relates the cost compared to the miles traveled for a Red Cab?
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope. it is expressed as ratio y change / x change when going from one point to another.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b.
costs are on the y axis, miles are in the x axis.
so, what points do we see on the chart for the red taxi ?
let's start with the point right in the y-axis : (0, 2).
that gives us the y- intercept automatically.
and then let's pick e.g. the point, where both lines cross : (3, 8).
so, for the slope we look at the coordinate changes :
x changes by +3 (from 0 to 3).
y changes by +6 (from 2 to 8).
the slope is then 6/3 = 2.
and again, the y- intercept is +2.
therefore, the line equation is
y = 2x + 2

The sum of two integers is 75. One of the numbers is three more than the other. What is the larger integer?
Step-by-step explanation:
Assign variables to the integers
Let the larger integer be 'A' and the smaller 'b'
Write Equations based on the Question
Since the sum of the integers is 75, then A + b = 75 (eq
1)
Since the larger number is three times more than the smaller, then A = 3b (eq2)
Combine the Equations and solve for variables
By substituting the value of A in eq1 into eq2
⇒ 3b + b = 75
4b = 75
b = ⁷⁵/₄ = 18.25
By substituting the value of b into eq1
⇒ A = 3(⁷⁵/₄)
A = ²²⁵/₄ = 56.25
∴ the larger integer is 56.25Check our Answer:
A + b = 56.25 + 18.75 = 75
39 is the answer
If $x$ is the larger integer, then the smaller integer is $x-3$. We find the sum and set it equal to 75:$$x+x-3=75\qquad\Rightarrow \qquad 2x=78\qquad\Rightarrow \qquad x=39$$The larger integer is $\boxed{39}$.

Heather ran a race at a constant rate. The table shows the time she reached each mile marker.
Let X represent the mile marker reached and let y represent the overall time passed.
Mile Marker: 0 | 1 | 2 | 3
Time (min): 0 | 8 | 16 | 24
(a) Write the equation in point-slope form to represent the mile reached over time
(b) Find the total time it will take Heather to run a 9-mile race if she maintains the same rate. Explain your reasoning.
Answer:
y − 8 = m(x − 1)
72 minutes
Step-by-step explanation:
Point slope form is: y − y1 = m(x − x1)
Pick any two points. I'll pick (1,8) and (2,16). I will make the first point the (x1,y1) we need for the point slope equation:
y − y1 = m(x − x1)
y − 8 = m(x − 1)
We can calculate the slope, m, by determining the Rise/Run of the line. The Rise is the change in y for the Run, the change in x.
Change in Run (x) = (2-1) = 1
Change in Rise (y) = (16-8) = 8
Slope (Rise/Run) = 8
m is 8
y − 8 = m(x − 1)
y − 8 = 8(x − 1)
or
y = 8x
We can now predict Heather's time to complete the 9 miles:
y = 8x
y = 8*(9)
y = 72 minutes

A man has 14 coins in his pocket, all of which are dimes and quarters. If the total value of his change is $2.30, how many dimes and how many
quarters does he have?
Answer:
8 dimes and 6 quarters
===================================================
Work Shown:
d = number of dimes
q = number of quarters
d+q = 14 since this is his coin total; equation solves to d = 14-q
10d+25q = 230 which is the total value in cents
10(14-q)+25q = 230 .... apply substitution rule
140-10q+25q = 230
15q+140 = 230
15q = 230-140
15q = 90
q = 90/15
q = 6 = number of quarters
d = 14-q
d = 14-6
d = 8 = number of dimes
-----------------
Check:
8 dimes + 6 quarters = 14 coins
8 dimes = 8*10 = 80 cents
6 quarters = 6*25 = 150 cents
8 dimes + 6 quarters = 80 cents + 150 cents = 230 cents = $2.30
The answers have been confirmed.

Answer:
m = 1
Step-by-step explanation:
We can start by moving all the terms with m to one side by subtracting m from both sides(to cancel out):
11m + 13 = m + 23
-m -m
10m + 13 = 23
Now, to single out the m term, we can subtract 13 from both sides:
10m + 13 = 23
- 13 -13
10m = 10
To find the value of m, we can divide both sides by 10:
10m = 10
÷ 10 ÷10
m = 1

The function h (d) = 2d + 4.3 relates the height (h) of the water in a fountain in feet to the diameter (d) of the pipe carrying the water in inches. Find h (1.5) and interpret your solution in the context of the problem find the value of d when h (d) = 10.3 and interpret your solution in the context of the problem
Answer:
h(1.5) = 7.3 ft
h(10.3) = 24.9 ft
Step-by-step explanation:
Given the function h(d) = 2d + 4.3,
where:
h = height of the water in a fountain (in feet)
d = diameter of the pipe carrying the water (in inches)
h(1.5)Substitute the input value of d = 1.5, into the function:
h(1.5) = 2(1.5) + 4.3
h(1.5) = 3 + 4.3
h(1.5) = 7 feet
The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.
h(10.3)Substitute the input value of d = 10.3, into the function:
h(10.3) = 2(10.3) + 4.3
h(10.3) = 20.6 + 4.3
h(10.3) = 24.9 feet
The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.
Context of the solutions to h(1.5) and h(10.3):The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.

Answer:
A. 2x - 1
Step-by-step explanation:
We want the price of each notebook, so we will get this equation.
(4x^2 + 2x + 1) / (8x^3 - 1) [ The " / " sign means I wrote as a fraction. ]
After that, we will use this method to factor ( 8x^3 - 1 ).
a^3 - b^3 = ( a - b )( a^2 + ab + b^2 )
1 can be wrote as 1^3 as we still get the same answer.
8^3 - 1^3 = ( 2x - 1 )( 4x^2 + 2x + 1)
So, we will get this.
(4x^2 + 2x + 1) / ( 2x - 1 )( 4x^2 + 2x + 1)
Now, we can cross out the ( 4x^2 + 2x + 1 ).
We will be left with 1 / ( 2x - 1 ).
Flip it and we will get ( 2x - 1 )
And that is the answer.
I hope it helps.

Given g(x)=5x+4, solve for x when g (x)=9
Answer:
g( 1 ) = 9
Step-by-step explanation:
Remember that in linear functions expressed in the function notation, g(x), this means that for any allowed value of x, we can use the equation to find the corresponding value of g(x) or y (output). Thus, the linear function g(x) = 5x + 4 is essentially the same as expressing the given equation as: y = 5x + 4.
Solution:Given the linear function, g(x) = 5x + 4, we can solve for x when g(x) = 9 by substituting the value of the output, g(x) = 9, into the function.
g(x) = 5x + 4
9 = 5x + 4
Subtract 4 from both sides:
9 - 4 = 5x + 4 - 4
5 = 5x
Divide both sides by 5 to solve for x:
[tex]\large\mathsf{\frac{5}{5}\:=\:\frac{5x}{5}}[/tex]
x = 1
Therefore, when g(x) = 9, the value of x = 1. Another way of expressing this is: g( 1 ) = 9.
