Answer:
35 minutes from 4:12 pm at 4:47 pm the tank will contain only 6617 liters of water.
Step-by-step explanation:
3:56-4:12 = -00:56 minutes passed
10452-8092=2360 liters of water lost
8092-6617=1475 liters
meaning: 56 mins lost 2360L
x mins lost 1475L
(the 2360 liters lost)/(the 56 minutes during which they were lost) is equal to the rate at which (the 1475 liters would be lost)/(the unknown amount of time)
2360/56 = 1475/x (cross multiply)
2360x = 1475(56)
2360x = 82600 (simplify)
x = 82600/2360 (divide to isolate x)
x = 35 (the unknown amount of time during which the water is lost)
4:12 pm plus 35 minutes is 4:47 pm.
The flow rate is the product of the speed of flow and the area through which the fluid flows
The time at which the tank will contain 6,617 L is 4:22 PM
Reason:
Known parameters are;
Volume of water in the tank at 3:56 PM = 10,452 L
Volume of water in the tank at 4:12 PM = 8,092 L
The rate at which water is flowing out of the tank, R, is given as follows;
[tex]Flow \ rate, \, Q = \dfrac{10,452 - 8,092}{3:56 - 4:12 } = 147.5[/tex]The flow rate, Q, of water out of the tank, Q = 147.5 L/min
The time it will take tank to contain 6,617 L, is given as follows;
Volume flow out = 10,452 L - 6,617 L = 3,835 L
The time it takes to flow to remain 6,617, t = [tex]\dfrac{3,835}{147.5} = 26[/tex]
It takes 26 minutes from the start before the water remaining is 6,617 L
Therefore, the time of the day, T = 3:56 PM + 26 minutes = 4:22 PM
The time at which the tank will contain 6,617 L is at 4:22 PMLearn more here:

What is the equation of a line of slope of 4 and pass through (-1,-6)
Answer:
The answer is
[tex] \huge y = 4x - 2[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question the point is (-1,-6) and slope 4
The equation of the line is
[tex]y + 6 = 4(x + 1) \\ y + 6 = 4x + 4 \\ y = 4x + 4 - 6[/tex]
We have the final answer as
[tex]y = 4x - 2[/tex]

Since the time series has trend and seasonal pattern, to forecast the quarterly sales of the textbook, the following regression equation was found: stack y t with overparenthesis on top equals 2120 space minus 620 space Q t r 1 space minus space 1320 space Q t r 2 space plus space 290 space Q t r 3 space plus space 24 space t , where Q t r 1 , Q t r 2and Q t r 3 are dummy variables corresponding to Quarters 1, 2 and 3, and t = time period. The sales in Quarter 4 of the next year are predicted to be
Answer:
Y(2)= 2120+ 48= 2168
Step-by-step explanation:
The given equation is
Yt= 2120 - 620 Qtr 1 t -1320 Qtr 2 t + 290 Q tr3 t + 24 t
Taking the quarter 1 , 2 and 3 to be dummy variable the predicted sales for the 4th qtr are
Yt= 2120 - 620 Qtr 1(0) -1320 Qtr 2(0) + 290 Q tr3 (0) + 24 (1)
Y(1)= 2120 + 24 = 2144 ( for year =1)
Y(2)= 2120+ 48= 2168 ( for year =2)
Y(3)= 2120 + 72= 2192 ( for year =3)
where t is the number of years.
So for the next year the fourth quarter sales are predicted to be 2168.

The mean of four numbers is 2.6
One of the four numbers is 5
Find the mean of the other three numbers.
Answer:
Step-by-step explanation:
the "mean" just means the "average"
So if the average of four numbers = 2.6
To find the total of the four numbers, you would multiply 2.6 by 4.
2.6 x 4 = 10.4
One of the four numbers is 5. (given in the question)
This means that the total of the remaining three numbers is:
10.4 - 5 = 5.4
Then divide 5.4 by 3 to find the average of the 3 numbers.
Mean of the other 3 numbers = [tex]\frac{5.4}{3}[/tex] = ?

What is the equation of the line that passes through the point (5,-7) and has a slope of negative 1
Answer:
y = -x - 2
Step-by-step explanation:
Use equation: y = mx + b, where "m" is the slope and "b" is the y intercept. You are given a slope of -1 for the m. This is usually expressed as just a "-", as the 1 is inferred.
Since you are given a point, plug the x and y values in to the equation.
-7 = -(5) + b
Solve for b:
-7 = -5 + b
-2 = b
Knowing "m" and "b", plug these in to get your final equation
y = -x - 2

A pallet full of soda contains 40 12-packs. The pallet itself weighs about 25 lbs and with
the pop weighs 410 lbs. How much does a can of pop weigh?
Answer:
0.802 lbs or 12.8 ounces(British).

Victor has a goal of making $75 per week at his after-school job. Last month he was within $6.50 of his goal. What are the maximum and minimum amounts that Victor might have made last month?
Answer:
maximum is 81.50
minimum is 68.50
Step-by-step explanation:
1m-751=6.50
m-75=6.50
m=81.50
/m-75=-6.5
m=68.50
The maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that Victor has a goal of making $75 per week at his after-school job. and Last month he was within $6.50 of his goal. Therefore, the maximum and minimum amounts that Victor might have made last month are,
Maximum and minimum amount = $75 ± $6.50
= $75+$6.50 , $75-$6.50
= $81.5 , $68.5
Hence, the maximum and minimum amounts that Victor might have made last month are $81.5 and $68.5, respectively.

m = 10 - 0 / 11 - 6
m = 10/5
m = 2
Therefore, the slope of the line is 2.
