The water level decreases 2 gallons every 3 seconds describes the rate of change shown in the grap
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given that Ariel is emptying the water from a 10 gallon cooler.
The graph shows the water level in the cooler as she empties it
Rate of change is change in water to change in time
(3, 8) and (0, 10) are the points from graph
Rate of change = 10-8/0-3
=-2/3
The minus sign is showing that is is decreasing
The water level decreases 2 gallons every 3 seconds
Hence, the water level decreases 2 gallons every 3 seconds describes the rate of change shown in the graph.

The equation A= 1750(1.04)t represents an account balance t years after the account was created. Which statement is correct?
A. The account balance will decrease 0.04% each year.
B. The account balance will increase 0.04% each year.
C. The account balance will decrease 4% each year.
D. The account balance will increase 4% each year.
Answer:
D. The account balance will increase 4% each year.
Step-by-step explanation:
Given the equation :
A= 1750(1.04)t
This is an exponential growth rate equation which has it's general format as :
A = A0 * (1 + r)^t
A0 = initial value,
Since (1 + r) is greater Than 1 ; then we conclude that it is a growth relation.
1 + r = 1.04
The rate, r = (1.04 - 1) = 0.04
r = 0.04 = (0.04 * 100%) = 4%
Hence, The account balance will increase 4% each year.

Answer:
9 ≤ x ≤ 7
Step-by-step explanation:
2x – 3 ≤ 11 or –8x – 10 ≤ – 82
We shall determine the value of x in both case.
2x – 3 ≤ 11
Collect like terms
2x ≤ 11 + 3
2x ≤ 14
Divide both side by 2
x ≤ 14/2
x ≤ 7
–8x – 10 ≤ – 82
Collect like terms
–8x ≤ – 82 + 10
–8x ≤ – 72
Divide both side by –8
x ≤ – 72 / –8
x ≥ 9 (since we divided by a negative sign)
9 ≤ x
Combining both answers
x ≤ 7
9 ≤ x
Thus,
9 ≤ x ≤ 7

A brick wall will be shaped like a rectangular prism. The wall needs to be 3ft tall and the builders have enough bricks for the wall to have a volume of 330 cubic feet. What tool can be used to find possible dimensions for the base of the wall?
Answer:
For a rectangular prism that has a base area B, and a height H, the volume is:
V = B*H
This is the only "tool" that we need to use in this situation.
We know that the wall needs to be 3ft tall, then H = 3ft
And we also know that we have enough bricks for a wall of a volume:
V = 330 ft^3
If we replace these two in the volume equation, we get:
330ft^3 = B*3ft
Now we can solve this for B, and thus find the volume of the base of the wall.
To do it, we just need to divide both sides by 3ft
(330 ft^3)/3ft = B*3ft/3ft
110 ft^2 = B
This means that the area of the base is 110ft^2
As the base is a rectangle of width W and length L, we must have:
110ft^2 = B = L*W
Then the possible measures of the base are given by the linear relation:
L = 110ft^2/W
Where we also need to add some trivial restrictions, like:
L > 0 ft
W > 0ft
This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.
You need a mean of at least 90 points to advance to the next round of the touch-screen trivia. What score in the fifth game will allow you to advance
Answer:
At least 98 is needed in the 5th game
Step-by-step explanation:
The missing parameters are:
[tex]Game\ 1 = 95[/tex]
[tex]Game\ 2 = 91[/tex]
[tex]Game\ 3 = 77[/tex]
[tex]Game\ 4 =89[/tex]
[tex]Mean = 90[/tex] at least
Required
The score in game 5 to make you advance
Mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
So, we have:
[tex]Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}[/tex]
[tex]Mean = \frac{352 + Game\ 5}{5}[/tex]
The mean must be at least 90.
So, we have:
[tex]\frac{352 + Game\ 5}{5} \ge 90[/tex]
Multiply both sides by 5
[tex]5 * \frac{352 + Game\ 5}{5} \ge 90 * 5[/tex]
[tex]352 + Game\ 5 \ge 450[/tex]
Make Game 5 the subject
[tex]Game\ 5 \ge450 - 352[/tex]
[tex]Game\ 5 \ge 98[/tex]
At least 98 is needed in the 5th game
The product of two consecutive even numbers is 224. What are these two numbers?
Answer:
14 and 16
Step-by-step explanation:
They are the ONLY consecutive even numbers
And also
x and (x+2)
x(x+2)=224 ( product of a number and the consecutive of that number)
x ²+ 2x-224=0
(x+16)(x-14) =0
x=-16 or 14
In this case 14 and (14+2) 14 and 16
The integers are either 14 and 16 or -14 and -16.

Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint does neil have
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint

1. Solve the following system of equations, show all your work on a separate sheet of paper, and check your answer. Write the solution as a point (x,y) (4 points).
3x + 5y = -40
–x + 4y = -15?
2. Suppose you and your friends form a band and you want to record a demo. Studio A rents for $125 plus $50 an hour and Studio B rents for $200 and $30 an hour. Let t = the number of hours and c = cost.
Write an equation to represent the cost at each studio (2 points)
Solve the system (2 points)
Write the solution as a point (x, y) (2 points)
Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A
C = 125 + 50t
Studio B
C = 200 + 30t
125 + 50t = 200 + 30t
20t = 75
t = 3.75
