A large industrial tank holds a maximum of 11,020 gallons of water. There is a drain on the bottom of the tank that allows 29 gallons per minute to drain out of the tank. Suppose the tank is full when the drain opened. How many gallons of water are left in the tank after one minute? Two minutes? Ten minutes? n minutes?
Volume of water in the tank after one minute is 10,991 gallons
Volume of water in the tank after two minutes is 10,962 gallons
Volume of water in the tank after one minute is 10,730 gallons
How to calculate the Flow rate?The given parameters are;
The volume of water the large industrial tank holds, V = 11,020 gallons
The rate of flow out of the tank through the drain on the bottom; Q = 29 gallons per minute
The initial level of water in the tank if the tank is initially filled is; 11,020 gallons
We want to find out the amount of water in gallons left in the tank after one minute.
The volume, V_out, of water that flows out of the tank after a given time, t, is given as follows;
V_out = Q × t
When t = 1 minute, we have;
V_out = 29 * 1
V_out = 29 gallons
The volume of water left in the tank, V_in tank , is given as follows;
V_in tank = V - V_out
Thus, volume left after one minute is;
V_in tank = 11020 - 29
V_in tank = 10991 Gallons
Similarly, after 2 minutes;
When t = 2 minute, we have;
V_out = 29 * 2
V_out = 58 gallons
The volume of water left in the tank, V_in tank , is given as follows;
V_in tank = V - V_out
Thus, volume left after two minutes is;
V_in tank = 11020 - 58
V_in tank = 10672 Gallons
Similarly, after 10 minutes;
When t = 10 minute, we have;
V_out = 29 * 1 0
V_out = 290 gallons
The volume of water left in the tank, V_in tank , is given as follows;
V_in tank = V - V_out
Thus, volume left after ten minutes is;
V_in tank = 11020 - 290
V_in tank = 10933 Gallons

Three men went into a second-hand shop to buy a
television.
It was priced in the window at £30.
Each of them handed over £10 to the shop assistant.
As the assistant opened the till, the manager had a quiet
word with him, "that TV is in the sale and is only £25
now, you will have to give them £5 back."
The assistant was very lazy and couldn't be bothered to
count out the right change for each man.
Instead, he took 5 £1 coins out of the till.
He put two of them in his own pocket and gave each
man £1 back.
Here's the problem:
The men have now paid £9 each for the TV.
The assistant has kept £2 for himself.
3 x £9 = £27.
£27 + £2 = £29.
But £30 was handed over in the first place.
WHERE IS THE MISSING £1?
Step-by-step explanation:
The trick here is to realize that this is not a sum of the money that the three people paid originally, as that would need to include the money the clerk has ($25). This is instead a sum of a smaller amount the people could have paid ($9 × 3 people = $27), added with the additional money that the clerk would not have needed had they paid that smaller amount ($27 paid - $25 actual cost = $2). Another way to say this is, the $27 already includes the bellhop's tip. To add the $2 to the $27 would be to double-count it. So, the three guests' cost of the room, including the bellhop's tip, is $27. Each of the 3 guests has $1 in his pocket, totaling $3. When added to the $27 revised cost of the room (including tip to the bellhop), the total is $30.
To obtain a sum that totals to the original $30, every dollar must be accounted for, regardless of its location.
Thus, the sensible sum can be expressed in this manner:
Jordan will hike the trail at a rate of 4mph. Write a linear equation to represent the distance Jordan still has to walk after x hours what does the y intercept represent
The linear equation would be y = 18 - 4x which represents the distance Jordan still has to walk after x hours.
The y-intercept represents the total distance Jordan has to walk.
What is the distance?Distance is defined as the product of speed and time.
We have to determine the distance.
So distance = speed× time
Given that his speed is 4 mph and x hours of walking, then:
So distance = 4 × x
Let it Start of the trail: 0 miles
And the end of the trail: 18 miles
The trail length is 18 miles, so if he walked 1 mile, 18 - 1 = 17 miles are left, in general:
⇒ y = 17 - 4(x)
Here y would be the distance Jordan still has to walk.
The y-intercept would be if substitute x = 0, then:
⇒ y = 17- 4(0)
⇒ y = 17
This represents the total distance Jordan has to walk
Hence, the linear equation would be y = 18 - 4x which represents the distance Jordan still has to walk after x hours.
The y-intercept represents the total distance Jordan has to walk.

The circle graph shows how the annual budget for a company is divided by department. If the amount budgeted for Media and Engineering combined is
$30,000,000, what is the total annual budget?
Answer: 150,000,000
Step-by-step explanation:
Total percentage of editorial + engineering = 20%
Total budget of editorial + engineering = 30,000,000
So, Total budget*20/100 = 30,000,000
Total budget = 5*30,000,000
Total budget = 150,000,000

The total cost of an annual pass for admission to a national
park plus camping for x days can be modeled by the function
f(x) = 20x + 80. A senior citizen pays $20 less than half of
this price for x days. What is the total cost for a senior citizen to
go camping for three days in the park?
The total cost paid by the senior citizen for 3 days = $50
Function word problemsThe function representing the total cost of the annual pass is:
f(x) = 20x + 80
A senior citizen pays $20 less than half of this price for x days
The total cost paid by the senior citizen = [tex]\frac{f(x)}{2} -20[/tex]
The total cost paid by the senior citizen =[tex]\frac{20x+80}{2} -20[/tex]
Simplify the resulting expression:
The total cost paid by the senior citizen =10x + 40 - 20
The total cost paid by the senior citizen = 10x + 20
x represents the number of days
Substitute x = 3 into the resulting equation
The total cost paid by the senior citizen for 3 days =10(3)+20
The total cost paid by the senior citizen for 3 days = $50

What number multiplied by 7/9 as a product of one
Answer:
★ How to do :-
Here, we are given with a fraction in which we are asked to find the second number in which we get it's product when multiplied as one. We aren't given with the appropriate first number but it's written in thr form of multiplication. If we multiply those numbers, we'll get the value of the first number. After finding the first number, we shift thr obtained value from LHS to RHS. We should always remember that while shifting the numbers, the sign of the appropriate number changes. So, let's solve!!
\:
➤ Solution :-
{\tt \leadsto 3 \: \bigg( \dfrac{7}{9} \bigg) \times x = 1}⇝3(97)×x=1
First, multiply the numbers on LHS.
{\tt \leadsto \bigg( \dfrac{3}{1} \times \dfrac{7}{9} \bigg) \times x = 1}⇝(13×97)×x=1
First solve the bracket on LHS.
{\tt \leadsto \dfrac{21}{9} \times x = 1}⇝921×x=1
Shift the first fraction from LHS to RHS, changing it's sign.
{\tt \leadsto x = 1 \div \dfrac{21}{9}}⇝x=1÷921
Take the reciprocal of second fraction and multiply both the fractions.
{\tt \leadsto x = \dfrac{1}{1} \times \dfrac{9}{21}}⇝x=11×219
Multiply the fractions now.
{\tt \leadsto x = \dfrac{9}{21}}⇝x=219
\:
{\red{\underline{\boxed{\bf So, \: the \: other \: number \: is \: \dfrac{9}{21}}}}}So,theothernumberis219
\:
Verification :-
{\tt \leadsto 3 \: \bigg( \dfrac{7}{9} \bigg) \times x = 1}⇝3(97)×x=1
Substitute the value of x.
{\tt \leadsto 3 \: \bigg( \dfrac{7}{9} \bigg) \times \dfrac{9}{21} = 1}⇝3(97)×219=1
Multiply the numbers on LHS in the bracket.
{\tt \leadsto \bigg( \dfrac{7 \times 3}{9 \times 1} \bigg) \times \dfrac{9}{21} = 1}⇝(9×17×3)×219=1
Multiply the numerators and denominators.
{\tt \leadsto \dfrac{21}{9} \times \dfrac{9}{21} = 1}⇝921×219=1
Multiply the numbers on LHS.
{\tt \leadsto \dfrac{21 \times 9}{9 \times 21} = 1}⇝9×2121×9=1
Multiply the numerators and denominators.
{\tt \leadsto \dfrac{189}{189} = 1}⇝189189=1
Write the fraction in lowest form on LHS.
{\tt \leadsto 1 = 1}⇝1=1
So,
{\sf \leadsto LHS = RHS}⇝LHS=RHS

Point A is located at (2,-2) on the coordinate plane. Point A is reflected over the Y-
axis to create point A'. Point A' is then reflected over the x-axis to create point A".
What ordered pair describes the location of A"?
Answer: A''=(-2, 2)
Step-by-step explanation:
A' = (2, -(-2)) = (2,2) ==> the y-coordinate is negated when A reflects over the y-axis
A''=(-(2), 2) = (-2, 2). ==> the x-coordinate is negated when A reflects over the x-axis
A''=(-2, 2)

Answer:
(-1, -4)
Step-by-step explanation:
y = -x is the 45° diagonal through the origin from top left to bottom right.
a reflection across that line brings anything that is in quadrant 1 (x and y are positive) to quadrant 3 (x and y are negative) like this point. and vice versa.
points in quadrant 2 stay in quadrant 2, points in quadrant 4 stay in quadrant 4.
but in every case x and y are exchanged and both signs are flipped like (-1, 2) turns into (-2, 1).

What is the constant of proportionality between y and x in the graph?
Answer: 4/3 or 2/1.5
Step-by-step explanation:
The constant of proportionality is also known as the slope. This can be found with change in y over change x.
Since we have a graph with distinct points, we can use rise over run. For this graph, we will count 3 units up from (0, 0) and 4 units right to (4, 3). This becomes 4/3 or 2/1.5. This is the constant of proportionality.
