The time taken to fill the tank using a pump that pumps 25L per minute
is 30.4 minutes
Given that A 1000L tank now contains 240L of water and asked the time taken to fill the tank using a pump that pumps 25L per minute.
The amount of water that can be filled in tank=760L
Given that a pump that pumps 25L per minute ,
The time required to fill 760L {if a pump that pumps 25L per minute }=[tex]\frac{760}{25}[/tex]
The time required to fill 760L {if a pump that pumps 25L per minute }=30.4 minutes
Therefore,The time taken to fill the tank using a pump that pumps 25L per minute is 30.4 minutes

Answer:
(0,-4)
Step-by-step explanation:
I'm pretty sure it would be (0,-4) though it may be counted wrong. A whole 180° is like if you start from the highest point, you'd be at the lowest point right after the turn. It doesn't really matter the direction with 180° in this case cause it's going to be the same outcome anyways. (Or so I'd think).

Answer:
5 trumpet players
Step-by-step explanation:
Given there are 10 fewer trumpet players than saxophone players, and the number of saxophone players is 3 times the number of trumpet players, you want to know the number of trumpet players.
SetupLet t represent the number of trumpet players. Then 3t is the number of saxophone players, and the difference in numbers is ...
3t -t = 10
SolutionCollect terms and divide by the coefficient of t:
2t = 10
t = 5
There are 5 trumpet players.
__
Additional comment
Check: There are 3 times as many sax players, so 15 of those. That's 10 more than the number of trumpet players.
You could have written the equation as ...
t +10 = 3t . . . . . . 10 more than the number of trumpets
Sometimes, when ratios are given:
t : s = 1 : 3
you can think in terms of "ratio units." Here, the difference is 3-1 = 2 ratio units, corresponding to a difference of 10 players. Then the multiplier of the ratio is 10/2 = 5:
t : s = 1 : 3 = 5 : 15 . . . . . . 5 trumpets and 15 saxophones.

What is the maximum number of solutions an
equation of the form ||ax − b| + c| = d can have?
Justify your reasoning with an example
Answer:
4 for c < 02 for c > 0Step-by-step explanation:
You want the maximum possible number of solutions to the equation
||ax -b| +c| = d
AnalysisThe values of 'a' and 'b' represent a vertical scale factor and a horizontal shift, so don't really contribute to the number of possible solutions. That means we can consider only the equation ...
||x| +c| = d
Positive c
We know |x| is always positive, and may have the same value for two different values of x. For positive 'c', the outside absolute value function does nothing, so the equation is effectively ...
|x| = d-c
For d < c, there can be no solutions. For d = c, there will be one solution, and for d > c, there will be two solutions.
Negative c
When 'c' is negative, then sum |x| +c may have either sign. This gives rise to another pair of possible solutions, for a total of four solutions.
GraphThe attached graph shows the two cases. The red graph shows the left side expression with c > 0; the purple graph shows the left side expression with c < 0. The orange horizontal line represents a value of 'd'. The number of intersection points with that horizontal line is the number of possible solutions to the given equation.
For c > 0, there are two possible solutions.
For c < 0, there are four possible solutions.

The responses to the questions involving the solution and equations of a straight line are;
6. The slope is -0.5
7. The equation is; y = x + 4
8. y = 7 - 0.25•x
9. The balance after m months is modeled by the equation;
B = 1,800 - 150•m
10. The slope is the monthly payment on the loan
How can a straight line equation be analyzed?6. The points on the graph in question 6 are; (0, 4), and (4, 2)
The slope is given by the ratio of the rise to the run of the graph as follows;
[tex]Slope = \frac{2 - 4}{0 - 4} = - 0.5[/tex]
The slope of the graph is -0.57. The equation in slope and intercept form is found as follows;
The given points are;
(-1, 3), and (-3, 1)
The slope and intercept form is presented as follows;
y = m•x + c
The point and slope form is presented as follows;
y - y1 = m•(x - x1)
Where m is the slope of the graph
m = (1 - 3)/(-3 - (-1)) = -2/-2 = 1
Which gives;
y - 3 = 1 × (x - (-1)) = x + 1
y = x + 1 + 3 = x + 4
y = x + 4The equation of the graph in slope and intercept form is; y = x + 4
8. The points are; (-4, 8), (4, 6)
Which gives;
m = (6 - 8)/(4 - (-4)) = -2/8 = -0.25
Therefore;
y - 8 = -0.25•(x - (-4)) = -0.25•x - 1
y = -0.25•x - 1 + 8 = -0.25•x + 7
y = 7 - 0.25•x9. The amount Zachary purchased the computer on loan = $1,800
The balance after 3 months = $1,350
The balance after 5 months = $1,050
Therefore;
The points on the graph of the equation that models the balance are therefore;
(0, 1,800), (3, 1,350), (5, 1,050)
Which gives;
B - 1800 = ((1,350-1,800)/(3-0))•(m - 0)
B - 1800 = -150•m
B = 1,800 - 150•mThe equation that models the balance, B, after m months is therefore;
B = 1,800 - 150•m10. The slope, ((1,350-1,800)/(3-0)) = -150, signifies the amount by which the balance reduces each month, which is the same as the amount Zachary pays each month, (the monthly payment).

-2(y + 1) + 5y = 3(y + 1) - 2
solve for y
Answer:
0 = 3 or No Solution
Step-by-step explanation:
a) Simplify both sides of the equation
−2(y + 1) + 5y = 3(y + 1) − 2
(−2)(y) + (−2)(1) + 5y = (3)(y) + (3)(1) + −2
−2y + −2 + 5y = 3y + 3 + −2
(−2y + 5y) + (−2) = (3y) + (3 + −2)
3y + −2 = 3y + 1
3y −2 = 3y + 1
b) Subtract 3y from both sides
3y − 2 − 3y = 3y + 1 − 3y
−2 = 1
c) Add 2 to both sides
−2 + 2 = 1 + 2
0 = 3 or No Solution

An employment agency specializing in temporary construction help pays heavy equipment operators $136 per day and general laborers $80 per day. If thirty-two people were hired and the payroll was $3960, how many heavy equipment operators were employed? How many laborers?
The number of heavy equipment operators employed is 26 while number of laborers employed is 6
How to solve Algebraic word problems?
Let x be the number of heavy equipment operators employed
Thus, If thirty-two people were hired, then we can say that;
32 - x represents the number of laborers employed
Thus, the equation to solve for x would be;
136x + 80(32 - x) = 3960
136x + 2560 - 80x = 3960
216x + 2560 = 3960
216x = 3960 - 2560
216x = 1400
x = 1400/216
x ≅ 6
Thus;
32 - x = 32 - 6 = 26
Thus, we conclude that number of heavy equipment operators employed is 26 while number of laborers employed = 6

What is the vertex and minimum and maximum of
y= -2/3|x-1|
The vertex of the function is (1, 0), the maximum is y = 0 and it has no minimum
How to determine the vertex and minimum and maximum of the function?The function is given as:
y = -2/3|x - 1|
The above function is an absolute value function
An absolute value function is represented as:
y = a|x - h| + k
Where the vertex is
Vertex = (h, k)
By comparing y = a|x - h| + k and y = -2/3|x - 1|, we have
(h, k) = (1, 0) --- vertex
a = -2/3
Because a = -2/3 is negative, then the vertex is a maximum
Hence, the vertex of the function is (1, 0), the maximum is y = 0 and it has no minimum

Encontrando un factor comun entre los 3 números dados, concluimos que cada pedazo de tronco debe medir 3 metros, y se obtendran 10 pedazos en total.
¿cuánto deben medir los pedazos de tronco si tienen que ser del mismo tamaño?Sabemos que los troncos miden 15, 9, y 6 metros, si los queremos cortar en pedazos de igual longitud, de tal forma que nada se desperdicie, entonces debemos encontrar un factor comun entre esos 3 numeros.
Los podemos reescribir como:
15 = 3*5
9 = 3*3
6 = 2*3
Entonces el unico factor comun entre las 3 longitudes es 3.
El tronco de 15 metros dará:
15/3 = 5 pedazos de tronco.
El tronco de 9 metros dará:
9/3 = 3 pedazos de tronco.
El tronco de 6 metros dará:
6/3 = 2 pedazos de tronco.

The old/Original value of the book before 30% increase in price is $70
Let us assume the old price of book before30% increase be x
Then the new price of the book after 30% increase would be x+ 30% of x
Which can be simplified as x+ 0.30x
Which further can be simplified 1.30x
As we are provided with the new price of book, we have to equate the above linear equation with the new price of the book
1.30x = $91
To solve the equation we need to move 1.30 from left hand side to right hand side which would change from to
