The slope of the line that contains the given points A(0,6), B(4,0) is -3/2.
It is given in the question that the line contains the points A(0,6) and B(4,0).
We know that:-
The formula to find the slope of a line that contains points (a,b) and (c,d) is given by:-
m = (d-b)/(c-a)
Here, we have
m = slope of the line
(a,b) = (0,6)
(c,d) = (4,0)
Hence, putting the values of (a,b) and (c,d) , we get
Slope of the line that contains the given points A(0,6), F(4,0) is given by:-
(0-6)/(4-0) = -6/4 = -3/2

Step-by-step explanation:
you know the area of a rectangle or square is length x width, we do the same here.
so we have a length of (x+5) and because its a square we do (x+5)(x+5) which is
[tex] {x}^{2} + 10x + 25[/tex]
and we know the area of the square is 30 so we make the expression above equal to 30 and take 25 away from both sides to get the wanted equation
The scores on the statistics test was normally distributed with a mean of 86 and a standard deviation of 5. Jose scored a 93 on his test. What percentage of the class scored less than he did?
The scores on the statistics test was normally distributed with a mean of 86 and a standard deviation of 5. Jose scored a 93 on his test then 1.4% of the class scored less than he did.
What is Normal Distribution?A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
The scores on the statistics test was normally distributed with a mean of 86, a standard deviation of 5, and Jose scored a 93 on his test.
We need to find the percentage of the class scored less than he did
z=(x-mean)/ S.D
=93-86/5
=7/5
=1.4
Therefore 1.4 percentage of the class scored less than Jose did.

10% of a water tank fills every 5 minutes. If you are filling a 40 gallon tank, how many gallons will there be in 30 minutes
explain step by step
By using cross mutliplication, there are 24 gallons in the water tank after 30 minutes.
How to estimate the filling time of a water tank by cross multiplicationAccording to the statement the water tank is full at constant rate, 10 % tank capacity per each 5 minutes. The tank has a capacity of 40 gallons. The gained capacity is determined by the following cross multiplication, where the water capacity is directly proportional to filling time:
x ∝ t
x = (n / 100) · V × (T / t) (1)
Where:
n - Initial capacity percentage of the water tank, in percentage.V - Full capacity of the water tank, in gallons.T - Final time, in minutes.t - Initial time, in minutes.x = [0.1 · (40 gal)] × (30 min / 5 min)

The sum of angles on a line is 180°. That means, 109° and a have to add up to 180°.
Angles that add up to 180° are called supplementary angles.

Write an equation for each vertical translation of y=f(x) .
2/3 unit down.
The equation for the vertical translation of y=f(x).2/3 unit down is y=f(x)-2/3.
Using equations of the form y=f(x), you may be able to modify the graph in various ways. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. Understanding these transformations makes it easy to graph different functions. Start with a "basic model" and apply a series of modifications to change it to the desired function.
A point on the graph of y=f(x) has the shape (x,f(x)).
The points on the graph of y=f(x)-2/3 are of the form (x,f(x)-2/3).
So, the graph for y=f(x) -2/3 is the same as the graph for y=f(x) shifted down by 2/3 units.
The new equation is:
y=f(x)-2/3

In a recent year the populations of china was 1.3x10^9According to the census data the population of the us was about 308,745,538 about how many times greater was the population of china than the population of the us step by step pleas
According to the census data, the population of China is more than the population of US by a factor 4.2
How to find how many times greater was the population of China over US populationGiven data
population of China = 1.3x10^9
population of US = 308,745,538
population of china = 1.3x10^9. can be rewritten as = 1,300,000,000
comparing the both figures representing population. we divide the population of China by the population of US
let the number of times the population of china is greater than population of US be x, such that
308,745,538 * x = 1,300,000,000
308,745,538x = 1,300,000,000
x = 1,300,000,000 / 308,745,538
x = 4.2106
x ≅ 4.2
We therefore say that the population of china is more than the population of US by a factor 4.2

What is the pitch when the wavelength is 5 feet? hertz
A) The type of variation between pitch and wavelength is an inverse variation. b) the pitch when the wavelength is 5 feet would be 132 hertz.
What is Inverse Variation?we know that the Inverse Variation is a relationship between two variables in which the product is a constant.
Let x be a pitch of a musical instrument
y be the wavelength
x*y=k
We need to find the value of k for x=220 hertz and y=3 ft
Then x*y=k
220*3=k
k=660
And for x=165 hertz , y=4 ft
x*y=k
165*4=660
k=660
A) Therefore, the type of variation between pitch and wavelength is an inverse variation.
B) the pitch when the wavelength is 5 feet;
x=?
y=5 ft
k=660
x*y=k
Then solve for x
x=k/y
x=660/5

How do I find (rs)(4)=?
How do i also find (r/s)(3)=?
The functions are express as follows:
(rs)(4) = 8(r / s)(3) = 2How to solve composite functions?A composite functions is gotten from the combination of two or more functions.
Therefore,
(rs)(4) = r(4) × s(4)
r(x) = 2√x
s(x) = √x
Hence,
r(4) = 2√4 = 2 × 2 = 4
s(4) = √4 = 2
Therefore,
(rs)(4) = r(4) × s(4) = 4 × 2 = 8
(r / s) (3) = r(3) / s(3)
r(3) = 2√3
s(3) = √3
Hence,

She was paid $15 an hour. The equation 50+15h=1250 represents the amount of money she has. 1. What could the 1250 represent in this situation? A. The amount of money she had saved before B. The amount of money she had at the end of the summer C. The amount of money she earned per hour D. The amount of money she earned per week 2. George said that 10 could not be the solution to the equation. Explain why he is correct (Hint: put 10 in the place of h). 3. Find the solution to the equation. Show your work.
The 1250 represents option B in the situation, George is correct, the solution to the linear equation is h = 80$.
What is a linear equation?
A linear equation has only one or two variables. No variable in a linear equation is raised to a power greater than one or used as the denominator of a fraction. When two values satisfying a linear equation are found and shown, all of the points on a coordinate grid fall on the same line.
Given that,
Jennifer was paid $15 per hour.
Given equation is 50+15h=1250
1)Here 1250 represent B.
Her financial situation towards the end of the summer.
Because as mentioned in the equation 50+15h=1250
Here, 50 is the money already there with her, and 15h was the amount paid to her,
So, by adding those both the amount 1250 will be the amount with Jennifer at the end of the summer.
2)Given equation is 50+15h=1250
By putting 10 in place of h (h=10)
50+15(10)=1250,
50+150=1250,
200=1250$.
Since, LHS is not equal to RHS.
Therefore, George is correct, 10 could not be the solution to the linear equation.
3) Given equation 50+15h=1250
15h=1250-50,
15h=1200,
h=1200/15,
h=80$.
Therefore, the solution for the equation h is 80$.

the price of a scooter and a cycle are in the ratio 5:2 if the scooter costs ruppes 4,200 more than the cycle ,whats the price of the cycle
The price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000
Let the price of the cycle be x
Then the price of the scooter will become X + 4200
As the price of a scooter and the price of a cycle are in the ratio of 5:2
So, it can be written as
x+4200: x:: 5:2
which implies
x= 2a and x+4200= 5a
a= x/2 and x+4200/5
equating both the equations, we get
x/2=(x+4200)/5
in order to solve this linear equation, we need to move 2 from the left-hand side to the right-hand side which would result in the change of sign from division to multiplication and we need to move 5 from the right-hand side to the left-hand side which would result in the change of sign from division to multiplication
5x=2x+8400
3x= 8400
X= 8400/3
X= 2800
So, the price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000
