Jay has a 50 gallon water tank. He fills the tank with a garden hose at a rate of 8. 2 gallons per minute. There are 9 gallons of water in the tank
What is the maximum amount of time Jay can add water without causing the tank to overflow?
The maximum amount of time Jay can add water without causing the tank to overflow is 5 minutes.
Given:
Jay has a 50 gallon water tank. He fills the tank with a garden hose at a rate of 8. 2 gallons per minute.
There are 9 gallons of water in the tank.
water tank to fill = water tank capacity - water in the tank.
= 50 - 9
= 41 gallons.
Time = 41 / 8.2
= 41 / 82/10
= 41*10 / 82
= 10/2
= 5 minutes.
Therefore the maximum amount of time Jay can add water without causing the tank to overflow is 5 minutes.

There are 60 books that are either hardcover or softcover. The hardcover books each weigh 26 ounces. The softcover books each weigh 12 ounces. The books weigh 1,056 ounces in all
The number of hardcover books is 24 and the number of the softcover book is 36.
Here we have to find the number of hardcover and softcover.
Here it is given that 60 books are there.
Let x be the number of hardcovers, so the number of software books is 60- x.
The weight of each hardcover is 26 ounces and of softcover is 12 ounces.
The total weight is 1056 ounces.
So we get:
26x + ( 60 -x) 12 = 1056
26x - 12x + 720 = 1056
14x = 336
x = 24
60-x = 60 -24 = 36
Therefore the number of hardcovers is 24 and the number of softcovers is 36.

The average age of a class of 25 students is 10 years and the average age of another class of 30 students is 15 years. Find the average age of students of the two classes.
The average age of the two classes is 12.73 yrs.
How do we calculate average?Average This is the arithmetic mean, which is computed by adding a set of integers and then dividing by the number of numbers in the set.The average is just the sum of all the numbers divided by the total number of values. The mathematical average of a group of two or more data values is defined as a mean. Average is also known as mean or arithmetic mean. Mean is merely a way of describing the sample's average.Total age of 25 students =25×10=250years.
Total age of 30 students =30×15=450years
∴ Total age of 55 students =250+450=700years

Question B: During what interval(s) of the domain is the baseball’s height staying the same?
(btw I have to write the question)
Step-by-step explanation:
what does it mean for an object to stay at the same height ?
come on, you cannot tell me you don't understand this.
it means that e.g. the object is at a certain height (e.g. 50 ft above the ground) at the beginning of a time interval. then 1 seconds later it is still at the same height. 1 seconds after that it is still at this height. and so on.
how do you think that shows on a chart that displays height on an up or down scale ? as a flat (horizontal) line.
the chart is simply a rough picture of what the object does in real life.
so, where do we have flat (horizontal) segments in the curve ?
between second 2 and second 6.
and then infinitely after second 12.
in interval notation
[2, 6] and [12, +infinity)
please note the round bracket on the infinity side. it means the indicated end of the interval is not included. that is, because infinity is just a concept and not a number. it can never be reached. and it is therefore not included in the interval itself.
FYI - the flat line between second 2 and second 6 is not possible in real life, unless it rolls on a flat surface or something is holding it steady in place for these 4 seconds.
but a flying ball can never have a pure flat curve regarding height. only when it comes at rest on the ground. gravity would not allow that. not even for a bullet shot by a gun.

How to determine the scale factor that was used to enlarge the triangles?The triangles that complete the question are added as an attachment
From the attached triangles, we have the following side lengths:
Triangle UVW
UV = 9 units
VW = 15 units
Also, we have
Triangle KLM
KL = 12 units
LM = 20 units
Because the triangle was enlarged from triangle UWV, it is expected that the side length of KLM will be greater than the corresponding side length of UVW
The scale factor of dilation is then calculated using the following scale factor formula
Scale factor = Side length of KLM divided by Side length of UWV
Mathematically, we have
Scale factor = KLM/UVW

The cold water faucet will fill the tub on its own in 5.6 minutes.
Let us assume the time taken by cold water faucet to fill the tub be x minutes. Now, the rate of hot water faucet to fill the tub = 1/14
Combined rate of filling by both faucets = 1/4
Rate of filling by hot water faucet + Rate of filling by cold water faucet = Rate of filling of tub by combination of two faucets
1/14 + 1/x = 1/4
1/x = 1/4 - 1/14
1/x = (14 - 4)/(4×14)

The standard form of the given equation is 5x - 4y = -3.
What is a standard form of an equation?
The standard form for linear equations in two variables is Ax+By=C.
What is a slope intercept form?
The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible. This form is frequently known as the y = mx + b form.
Here, we have
y = 5/4x+3/4
we have to convert this equation into standard form
y - 5/4x = 3/4
y - 5/4x - 3/4 = 0
4y - 5x - 3 = 0
4y - 5x = 3
5x - 4y = -3

An online furniture store sells chairs for $200 each and tables for $600 each. Every day, the store can ship no more than 40 pieces of furniture and must sell no less than $12000 worth of chairs and tables. If xx represents the number of tables sold and yy represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
If the minimum 30 chairs were sold , then the minimum number of Tables sold is 10.
Given as :
The cost of each chair = $ 200
The cost of each table = $ 600
The total number of furniture sold per day = 40
The minimum amount of selling per day = $ 12000
Let the total number of chair = C
The total number of table = T
So , according to question
C + T = 40 .......1
200 C + 600 T = 12000 .......2
Solving eq 1 and 2
200 C + 600 T = 12000
200 × ( C + T ) = 40 × 200
i.e 200 C + 200 T = 8000
or, ( 200 C + 600 T ) - ( 200 C + 200 T ) = 12,000 - 8000
Or, 400 T = 4000
i.e T = 10
Put The value of T in eq 2
So, 200 C + 600 × 10 = 12000
or , 200 C + 6000 = 12,000
Or, 200 C = 12000 - 6000
Or, 200 C = 6000
i.e C = 30
The number of chair sold is 30
If the number of chair sold is 10 ,
Then the min number of table sold = 200 × 30 + 600 T = 12000
i.e 600 T = 12000 - 6000
or, 600 T = 6000
∴ T = 10
I.e T = 10
Hence, if the minimum 30 chairs were sold , then the minimum number of Tables sold is 10 .
