The unit rate is 10 minutes per meters.
What is rate of time?
Time is in units of seconds, minutes, hours, or years. Rate is distance per time, so its units could be mph, meters per second, or inches per year.
rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute.
Given,
she fills 4/5 meters in 8 minutes.
let x be the time she fills minutes per liter.
4/5 meters ⇔ 8 minutes
1 meter ⇔ x minutes
Cross multiplying
4/5*x = 1*8
x = 5*8/4
x = 10 minutes
The unit rate is 10 minutes.

what is 7 1/5 divided by 8 in fraction form and as a mixed number
7 1/5 divided by 8 in fraction form is 36 / 40 = 9/ 10 and in decimal form = 0.9
A fraction is a numerical expression expressing a portion of the whole. There are two parts: a numerator and a denominator. The denominator is the total number of pieces that make up the whole, while the numerator is the number of equally sized portions of the whole. For instance, in the percentage of 3/8 has a denominator of 8 and a numerator of 3.
We have been given that -
7 1/5 divided by 8
Rewrite as
(36/5) / 8
36 / 5×8
Multiplying 5 with 8 and we get
36 / 40
Follow these steps to convert an incorrect fraction to a mixed number: Subtract the denominator from the numerator. The quotient's whole number component should be written down. Write the leftover amount on top of the original denominator.
36/ 40 in decimal form = 0.9
0.9 = 0.9 × 10 /1 × 10
= 9 / 10
Hence, When 7 1/5 is divided by 8, the result is 36/40 (9/10) and 0.9 (in decimal notation).

Where does the graph of y= -2x + 1 intersect the x-axis?
The graph intersects the x-axis at ( 1/2 , 0) .
A cartesian coordinate system, which uses signed distances between two fixed perpendicular oriented lines and the point measured in the same unit of length, uniquely identifies any point in a plane by a pair of numerical coordinates.
The origin of each reference coordinate line, known as an x-axis or y-axis of the system or simply an axis (plural axes), is the intersection of the ordered pairs (0, 0).The coordinates can also be determined by looking at the locations of the perpendicular projections of the point onto the x- axis and y -axis, which are shown as signed distances from the origin.We know that at the x-axis the value of y is 0 .
Now substituting the value of y in the equation of the graph we get :
y = - 2x + 1
at y = 0 ,
0 = -2x + 1
or, -1 = -2 x
or, x = 1 / 2
Hence the co-ordinate of the point where the graph passes through x-axis is ( 1/2 , 0 ) .

a. Write an inequality for this situation. Let x represent the number of miles ridden.
b. What is the greatest number of whole miles Ivan can ride without going over his spending
limit?
Using a linear function, it is found that:
a. The inequality for this situation is: 5 + 0.45x ≤ 12.
b. He can ride at most 15 miles without going over the limit.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).For the context of this problem, the slope and the intercept are defined as follows:
The slope is the cost per mile, hence m = 0.45.The intercept is the flat cost, the renting fee of b = 5.Hence the cost function, considering x miles, is given as follows:
C(x) = 0.45x + 5.
He wanted to spend $12 or less on a beach bike rental, hence the inequality that models this situation is given by:
C(x) ≤ 12.
5 + 0.45x ≤ 12.
The inequality is solved similarly to an equality, isolating the variable and finding the range of values, hence the solution is found as follows:
0.45x ≤ 7
x ≤ 7/0.45
x ≤ 15.6 miles.
The greatest whole number of miles is of 15 miles, as for 16 miles, the cost would be above $12.

The rate of change (m) = 9
The starting number (b) = 100
The equation is: y = 9x + 100
(0, 100) is the ordered pair for the starting number.
See the image for the graph of y = 9x + 100.
How to Create and Graph the Equation of a Line?To create the equation of a line, we need to determine the following:
Y-intercept/starting value = b
Slope of the line/rate of change = m
The ordered pair of the y-intercept or starting value is represented as (0, b), where b is the value of y on the y-axis where the line intercepts the y-axis and x = 0 at this point.
These values can be substituted into y = mx + b, which represents the equation of the line in slope-intercept form.
From the information given, we have:
Y-intercept/starting value (b) = 100
Slope of the line/rate of change (m) = 9
To write the equation of the line, substitute m = 9 and b = 100 into y = mx + b:
y = 9x + 100
The ordered pair for the starting number would be: (0, 100).

What is the solution to the linear-quadratic system of equations.
The solution to the linear-quadratic system of equations are: [tex]\begin{pmatrix}x=1,\:&y=3\\ x=-5,\:&y=-3\end{pmatrix}[/tex].
Quadratic Function
The Standard form for a quadratic equation is ax²+ bx + c=0, where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
To solve a quadratic function, you should find the discriminant: D=b²-4ac and then use this variable in the formula: [tex]x=\frac{-b\±\sqrt{\Delta} }{2a}[/tex].
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=4x+3. Where:
m= the slope. It can be calculated for Δy/Δx .
b= the constant term that represents the y-intercept.
The question asks the solution of the system the following equations
y=x²+5x-3 (1)
y=2+x (2)
Firstly, you should subtract equation 1 and 2, as result, you have
y-y= x²+5x-3 -(2+x)
y-y= x²+5x-3 -2 -x
0= x² +4x -5
After that for finding x, you should solve the equation x² +4x -5=0. Then,
D=b²-4ac
D= 4²-4*1*(-5)
D=16+20
d=36
Thus,
[tex]x=\frac{-b\±\sqrt{\Delta} }{2a}= \frac{-4\±\sqrt{36} }{2*1}= \frac{-4\±\ 6 }{2}[/tex]. Therefore

At the beginning of the year, Salma had $35 in savings and saved an additional $8 each week thereafter. Henry started the year with $95 and saved $5 every week. Let SS represent the amount of money Salma has saved tt weeks after the beginning of the year and let HH represent the amount of money Henry has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved.
The number of weeks when Salma and Henry would have the same amount of money is 20 weeks.
How many weeks would they have the same amount?The form of the equations that represent the total amount of money saved is :
Total amount in the account = initial amount in the account + (amount added each week x number of weeks)
SS = $35 + ($8 x tt)
SS = $35 + $8tt
HH = $95 + ($5 x tt)
HH = $95 + $5tt
When they have the same amount in their account, the two equations woud be equal.
HH = SS
$95 + $5tt = $35 + $8tt
$95 - $35 = $8tt - $5tt
$60 = $3tt

He has a budget of $35. A four pack of markers costs $5.49, including tax. Write and solve an inequality, using x for the variable, to solve for the number of packs of markers Mr. Sowers can purchase. Copy/paste one of the following inequality symbols to help you write your inequality: ≤ < ≥ >
The number of packs of markers that Mr. Sowers can purchase is 6.
How many packs can he buy?The maximum amount that Mr. Sowers can spend is $35. This means that the amount can either by $35 or less than $35. Thus, the inequality sign that would be used is the less than or equal to sign, ≤ .
total amount spent on the packet of markets ≤ budget
(cost of one packet x number of packets) ≤ $35
$5.49x ≤ $35
In order to determine the value of x, divide both sides of the equation by 5.49
x ≤ $35 / 5. 49
x ≤ 6.38
x ≤ 6
