Answer: x = [tex]\frac{-31}{23}[/tex], y = [tex]\frac{-9}{23}[/tex], z = [tex]\frac{-83}{23}[/tex]
Step-by-step explanation :Solving system of equations
Given the following system of equation below
- 4x + 2y + z =1 .......(1)
x − y + 3x = −5 ........(2)
3x + y − 4z = 10.........(3)
first we solve eq 1 and eq 3:
we get, -13x + 9y = 14 ..........(4)
Now we solve eq 2 and eq 4 and get value of x and y:
we get, x = [tex]\frac{-31}{23}[/tex] and y = [tex]\frac{-9}{23}[/tex]
finally we put value of x and y in eq 1 and get the value of z:
-4(-31/23) + 2(-9/23) + z = 1
106/23 + z = 1
z = 1 - 106/23
z =[tex]\frac{-83}{23}[/tex]

The Henderson family and the Ramirez family each used their sprinklers last summer. The water output rate for the Henderson family's sprinkler was 40 L per hour. The water output rate for the Ramirez family's sprinkler was 35L per hour. The families used their sprinklers for a combined total of 55 hours, resulting in a total water output of 2125 L. How long was each sprinkler used?
Answer:
Henderson family spent 40 hrs, while Ramirez spent 15 hrs.
Step-by-step explanation:
Let t = time in hrs the Henderson family used their sprinkler
Let 55 - t = time in hrs the Ramirez family used their sprinkler.
40t+35*(55-t)=2125
40t+1925-35t=2125
calculcate this and you will get t=40.
then 55-40=15.
So, Henderson family spent 40 hrs, while Ramirez spent 15 hrs.

Answer: hope this help
step-step explanation:
A pole 11 feet tall is used to support a guy wire for a tower, which runs from the tower
to a metal stake in the ground. After placing the pole, Violet measures the distance
from the pole to the stake and from the pole to the tower, as shown in the diagram
below. Find the length of the guy wire, to the nearest foot.
The length of the guy wire, to the nearest foot is 48 ft.
What is mean by foot of Maths?A unit of length (or distance) in US units equal to 12 inches. The abbreviation is: ft. Or sometimes the single quote mark: ' Example: 10 feet can be written 10 ft, or just 10' A foot is exactly 0.3048 meters in the Metric System (the foot is defined that way).
Step-by-step explanation:
Here, we want to find the length of the wire
from the diagram, we can identify two similar triangles
The smaller one and a bigger one
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
We can start by getting the height of the tower
we have this as:
8/11 = 28/x
8 * x = 28 * 11
8x = 308
x = 308/8
x = 38.5 ft
So as we can see, the wire represents the hypotenuse of the larger triangle that measures 28 ft base and 38.5 ft height
So we can use the Pythagoras’ theorem to get the hypotenuse
Let us call this g mathematically;
According to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
thus, we have it that;
g^2 = 38.5^2 + 28^2
g^2 = 2,266.25
g = √2,266.25
g = 47.61 which is approximately 48 ft

The fraction model below shows the steps that a student performed to find a quotient. Which statement best interprets the quotient?
The statement that best interprets the quotient is "there are 6( 1/4 ) two - third in 4( 1/6 )".
In mathematics, the sum obtained by diluting two numbers is known as a quotient. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.
Any integer may be used as the larger number in a fraction, which is a number that represents a percentage of the larger number. It is shaped like a denominator and a numerator.
For step 1:
The shaded part is:
4 + 1/6 = 4(1/6) = 25/6
Now, dividing the shaded part by the unshaded part,
( 25/6 ) / ( 2/3 ) = ( 25/6 ) × ( 3/2 )
( 25/6 ) / ( 2/3 ) = 25/4
( 25/6 ) / ( 2/3 ) = 6( 1/4 )

Step-by-step explanation:
Suppose the Kalamazoo Brewing Company (KBC) currently sells its microbrews in a seven-state area: Illinois, Indiana, Michigan, Minnesota, Mississippi, Ohio, and Wisconsin. The company’s data analytics department has collected data from its distributors in each state. This data consists of the quantity and price (per case) of microbrews sold in each state, as well as the average income (in thousands of dollars) of consumers living in various regions of each state. The data for each state are available via the link below--please note there are multiple tabs at the bottom of the spreadsheet, each refers to one of the seven states selling the Kalamazoo Brewing Company’s microbrews. Excel Data File Assuming that the underlying demand relation is a linear function of price and income, use your spreadsheet program to obtain least squares estimates of Ohio’s demand for KBC microbrews.
Let's say that the Kalamazoo Brewing Company (KBC) now distributes its microbrews across a region that includes seven states: Illinois, Indiana, Michigan, Minnesota, Mississippi, Ohio, and Wisconsin. Data from the company's distributors in each state has been gathered by the data analytics division. This information includes the volume and cost of microbrews (per case) sold in each state as well as the average annual income (in thousands of dollars) of customers residing in various states' areas. Please notice that there are several tabs at the bottom of the spreadsheet, each of which corresponds to one of the seven states where the microbrews of the Kalamazoo Brewing Company are sold. The statistics for each state are available via the link below. Data File in Excel Using the supposition that the fundamental demand relationship is a linear function of price and income, utilize
With your spreadsheet application, you may predict Ohio's demand for KBC microbrews using least squares.
Ohio's demand for KBC microbrews is estimated using least squares as follows: Price + Income = 1.57 times the quantity.
Note: Sheet1 of the attached Excel document has a replication of the data from the question, and Sheet2 contains the results of the regression analysis.
Rounding to two decimal places, we find the following coefficients in the second column of the third table in Sheet2:

A plumber charges a one-time surcharge fee of $50 for
emergency calls plus a rate of $65 per hour. Write a function
using function notation to determine the total amount charged
for an emergency service call. Then find f(4.5), and explain the
real-world interpretation of f(4.5).
Answer:
f(x) = $65x + $50
f(4.5) = $342.5
The real-world interpretation of f(4.5) would be an emergency service call where they have to work for 4.5 hours.
Step-by-step explanation:
We will write a function where x is the hours. Since you pay $65 for every hour, we will multiply $65 by x. Next, there is a fee of $50 so we will add that onto the end.
f(x) = $65x + $50
Now, we will plug 4.5 into the function for x and solve.
f(x) = $65x + $50
f(4.5) = $65(4.5) + $50
f(4.5) = $292.5 + $50
f(4.5) = $342.5
The real-world interpretation of f(4.5) would be an emergency service call where they have to work for 4.5 hours.

19m=55.5 − 5
5m=19−55.5
m=55.5−19/5
55.5=19m+5
The equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C.
m = (55.5 - 19)/5
How do we come up with the Equation?We are to deduce from the question the equation that may be used to calculate, m, the average number of miles she would have to ride to reach her objective.
Given:
"Arianys wants to ride her bicycle 55.5 miles"
and
"She has already ridden 19 miles"
Hence,
The number of miles she needs to ride more is
55.5 miles - 19 miles
= 36.5 miles
'
If m is the average number of miles she must cycle in 5 days to reach her objective,
Then, we can write that
m = 36.5/5
OR
m = (55.5 - 19)/5
As a result, the equation that may be used to get m is 5m = 55.5 - 19.

Find the piecewise linear equation that models the data above. Round to three decimal places if needed.
y={
___ x + ___. −9 ≤ x ≤ −3
___ x + ___. −3 < x ≤ 4
___ x + ___. 4 < x ≤ 10
The piecewise linear function that models the situation is given as follows:
y = -4/3x + b, −9 ≤ x ≤ −3,y = -8/7x - 17/7, −3 < x ≤ 4,y = 17/6x - 110/6, 4 < x ≤ 10.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.A piecewise function is a function that has different definitions based on the input.
For x between -9 and -3, the function decreases by 8 when x increases by 6, hence the slope is given by:
m = -8/6 = -4/3, hence:
y = -4/3x + b.
When x = -9, y = 9, hence we use it to find b as follows:
9 = -4/3(-9) + b
9 = 12 + b
b = -3.
Thus the first definition is:
y = -4/3x + b, −9 ≤ x ≤ −3
For x between -3 and 4, the function decreases by 8 when x increases by 7, hence the slope is given by:
m = -8/7
y = -8/7x + b.
When x = -3, y = 1, hence we use it to find b as follows:
1 = -8/7(-3) + b
1 = 24/7 + b
b = -17/7
Thus the second definition is:
y = -8/7x - 17/7, −3 < x ≤ 4.
For x between 4 and 10, the function increases by 17 when x increases by 6, hence the slope is given by:
m = 17/6
y = 17/6x + b.
When x = 10, y = 10, hence we use it to find b as follows:
10 = 17/6(10) + b
b = 10 - 170/6
b = -110/6
Thus the third definition is:
y = 17/6x - 110/6, 4 < x ≤ 10

a) Calculate the size of each payment during the first year.
b) What is the size of the final payment (payment at the end)?
Answer:
Step-by-step explanation:
(a).
Within 1 year, there would be 4 payments to be made.
therefore, PMT= [tex]\frac{P(1+i)}{n} = \frac{2500(1+0.025)}{4*5} =\frac{2562.5}{20} = $128.125[/tex]
(i) 1st payment will be :PMT $128.125
(ii) 2nd payment will be :128.125*(1.025)^1= $131.33
(iii) 3rd payment will be :128.125*(1.025)^2=$134.61
(iv) 4th payment will be :128.125*(1.025)^3=$137.98
Hence the payments are: $128.125, $131.33, $134.61, and $137.98.
(b).
The size of the final payment [tex]PMT(1+i)^{m-1}[/tex] where m 4 *5= 20
[tex]=128.125(1+0.025)^{20-1} \\=128.125(1.025)^{19} \\=$204.83[/tex]
