Answer:
128 fluid ounces
Step-by-step explanation:
As per linear equation, there are 128 ounces of fluid in a gallon.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given relations for any fluid is:
1 cup = 8 ounces
1 pint = 2 cups
1 quart = 2pints
1 gallon = 4 quarts
Therefore,
1 gallon
= 4 quarts
= 4 (2) pints
= 8 pints
= 8(2) cups
= 16 cups
= 16(8) ounces
= 128 ounces
Therefore, for any particular fluid 128 ounces equal to 1 gallon.

Step-by-step explanation:
hope it helps, please mark as brainliest
plz help meeeeeeeeeee
Answer:
Please check the explanation.
Step-by-step explanation:
We know the equation
y = kx
k = y/x
where k is the proportionality constant
so,
First ratio can be calculated as
Miles = 45
Hours = 3/4
The ratio = 45 / (3/4)
= (45 × 4) / 3
= 180/3
= 60
Thus, the proportionality constant = 60
Thus, the remaining ratios can be calculated as:
The Pair (135, Hours)
135/Hours = 60
Hours = 135 / 60
= 27/12
= 9/4
= 2.25
Thus, the pair is (135, 2.25)
The Pair (Miles, 3)
Miles/3 = 60
Miles = 60×3
= 180
The Pair (90, Hours)
90/Hours = 60
Hours = 90 / 60
= 3/2
= 1.5
Thus, the complete table:
Miles 45 135 180 90
Hours 3/4 9/4 3 3/2
Verification:
Miles / Hour = 45/(3/4) = 60
Miles / Hour = 135 / 2.25 = 60
Miles / Hour = 180 / 3 = 60
Miles / Hour = 90 / 1.5 = 60

A figure has the following vertices: A(0,4), B(3,8), and C(4,0). What are the vertices of the figure after a reflection across the x-axis?
Answer:
A -> (0,-4)
B -> (3, -8)
C -> (4, 0)
Step-by-step explanation:
Hiya! When it came to this, the goal of shifting a figure across the x-axis is to get it flipped across the horizontal line. By doing this, which I may potentially be incorrect on, I assumed that you would have to take the negatives of the y values in order to make that shift downwards. I left the x-values be, as I believe they remain stable when you're only doing a reflection across the x-axis. C also remained the same, as a negative of a zero is still a zero. If you would like to see this change graphed out, I would recommend plugging the coordinates into Desmos to see the shapes. I hope this at least helped a little!
The amount of time it takes a water pump to empty a tank varies directly as the capacity of the tank. If it takes a water pump 2.5 hours to empty a tank containing 60,000 gallons of water, how long does it take the same pump to empty a tank containing 108,000 gallons of water?
Answer: 4.5 hours
Step-by-step explanation: i used cross multiplication.
2.5/x=60,000/108,000
60,000x=270,000
divide 270,000 by 60,000
x=4.5
An equation is formed when two equal expressions. The time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that the amount of time it takes a water pump to empty a tank varies directly with the capacity of the tank. Therefore, the relationship can be written as,
V ∝ T
V = kT
Substituting the volume and time in the equation,
60,000 gallons = 2.5 hours × k
Solving the equation for k,
k = 60,000 gallons / 2.5 hours
k = 24,000 gallons per hour
Now, the equation for the relationship can be written as,
V = 24,000 gallons per hour × T
Now, the time the same pump will take to empty a tank containing 108,000 gallons of water is,
V = 24,000 gallons per hour × T
108,000 gallons = 24,000 gallons per hour × T
108,000 gallons / 24,000 gallons per hour = T
T = 4.5 hours
Hence, the time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

Gerry's electric toothbrush rotates the brush 125 times per second.
Gerry brushes her teeth for two minutes, twice a day.
How many rotations does her electric toothbrush make in one week?
Answer:
Her electric toothbrush makes 210,000 rotations in one week
Step-by-step explanation:
Note that:
1 minute = 60 seconds1 week= 7 days∵ Gerry brushes her teeth for two minutes, twice a day
→ Twice means times 2
∴ Gerry brushes her teeth for 2 × 2 = 4 minutes a day
∵ Gerry's electric toothbrush rotates the brush 125 times per second
∵ 1 minute = 60 seconds
→ Multiply 125 by 60 to find the number of rotating in 1 minute
∴ Gerry's electric toothbrush rotates 125 × 60 = 7,500 in 1 minute
∵ Gerry brushes her teeth for 4 minutes a day
→ Multiply it by 4 to find the number of rotation in 1 day
∴ Gerry's electric toothbrush rotates 7,500 × 4 = 30,000 in 1 day
∵ 1 week = 7 days
→ Multiply the number of rotation in 1 day by 7 to find it in 1 week
∴ Gerry's electric toothbrush rotates 30,000 × 7 = 210,000 in 1 week
∴ Her electric toothbrush makes 210,000 rotations in one week
Find sin theta if cot theta = -2 and cos theta < 0
cot(θ) = cos(θ)/sin(θ)
So if both cot(θ) and cos(θ) are negative, that means sin(θ) must be positive.
Recall that
cot²(θ) + 1 = csc²(θ) = 1/sin²(θ)
so that
sin²(θ) = 1/(cot²(θ) + 1)
sin(θ) = 1 / √(cot²(θ) + 1)
Plug in cot(θ) = -2 and solve for sin(θ) :
sin(θ) = 1 / √((-2)² + 1)
sin(θ) = 1/√(5)

Which ordered pair is a solution of the equation y=5x? (-2, 10) (-5, 25) (-3, 15) (-2, 10)
One of the solutions of the given equation y = 5x is (2,10)
The solution of an equation means if we substitute the value of this solution into the equation, it will produce the correct equality from the left side to the right side.
If the solution has 2 variables, for example x and y, and the solution is (a,b) means that if we replace x with a and y with b, the equality is correct.
The given equation is: y = 5x
For option (-2,10), substitute x = -2 and y = 10 into the equation:
10 = 5 . (-2)
10 = -10 (False)
Hence (-2,10) is not a solution.
For option (-5, 25), substitute x = -5 and y = 25 into the equation:
25 = 5 . (-5)
25 = -25 (False)
Hence (-5, 25) is not a solution.
For option (-3, 15), substitute x = -3 and y = 15 into the equation:
15 = 5 . (-3)
15 = -15 (False)
Hence (-3, 15) is not a solution.
There is no options in the problem that gives the correct equality. Looks like there is a typo.
Example of a solution of the given equation is (2,10), since if we substitute x = 2 and y = 10 into the equation:
10 = 5 . (2)
10 = 10 (True)
Hence (2, 10) is a solution.

smallest 1000 = 3^3 = 27
biggest 2222 = 2*27+2*9+2*3+2 = 802 digits base 6smallest 10 = 36biggest 1000-1 = 6^3-1 = 4095.
So the intersection of these is 36 to 80 , 80-36+1 = 45
sum of numbers from 36 to 80 = (45/2)(72+44) = 45/2*116= 45*58 = 2610 average = 2610/45 =58A more straight forward approach would be to say that of there are 45 numbers the median on is in the 46/2 = 23rd position.
In this case the median and the mean will be the same. 36+23-1 = 58.
The median is the middle number in a sorted, ascending or descending list of numbers and can be more descriptive of that data set than the average. It is the point above and below which half (50%) the observed data falls, and so represents the midpoint of the data.
Median is not dependent on all the data values in a data set. The median value is fixed by its position and is not reflected by the individual value. The distance between the median and the rest of the values is less than the distance from any other point.

Part B
the 4 ordered pairs for the given proportional relation are (1, 7), (2, 14), (3, 21), (4, 28).
How to find the set of ordered pairs?
Here we know that the sloth travels about 7 feet every minute, then we can define the speed as:
S = 7 ft/min
Now remember the relation:
distance = speed*time
Then the proportional relation is:
D = 7*t
The ordered pairs are of the form (t, D)
if t = 1.
D = 7*1 = 7
if t = 2
D = 7*2 = 14
if t = 3
D = 7*3 = 21
if t = 4
D = 7*4 = 28
Then the 4 ordered pairs are (1, 7), (2, 14), (3, 21), (4, 28).
