Answer:
x = -4/17
Step-by-step explanation:
Working together, two pumps can drain a certain pool in 3 hours. If it takes the older pump 12 hours to drain the pool by
itself, how long will it take the newer pump to drain the pool on its own?
Do not do any rounding.
The more recent pump can clean the pool itself in 4 hours, as per the question we have.
What are a pump and a type?Pumps are primarily classified into two broad categories: 1. Kinetic and dynamic pumps. Fluid passing by or through the impeller of a dynamic pump is given velocity and pressure.
Let's refer to the earlier pump's rate as "p1" and the more recent pump's rate as "p2."
The older pump took 12 hours to drain the swimming pool on its own.
Together, the two pumps' operating time equals 3 p1, or 1/12 of the pool's volume each hour.
And if the pool can be drained by the two pumps over 3 hours, so p1 + p2 equals one-third of a water's volume each hour.
We can solve for p2:
p2 = (1/3) - p1
p2 = (1/3) - (1/12)
p2 = 1/4 of the pool's volume per hour.
So the newer pump can drain the pool by itself in 4 hours.

What is thirty five thousandths as decimal numerals
Answer: Thirty five thousandths as decimal numerals is 0.035
The value of thirty five thousandths as decimal numerals is 0.035.
We are given that;
Decimal numerals =Thirty five thousandths
Now,
One thousandth is equal to 0.001,
so thirty five thousandths is equal to 0.001 x 35 = 0.03512.
Also, it is moving the decimal point three places to the left of 35, since there are three zeros in 1000
Therefore, by decimal the answer will be 0.035.

Devon sells used laptop computers. He recorded the ages of some laptops and the prices for which they sold in this scatterplot
Answer:
B. (6, 325) and (21, 200).
Step-by-step explanation:
A line of best fit that that would best represents and show the trend between two variables on a scatter plot is a line drawn to connect points that will produce a line whereby most of the data points would be clustered around the line or not much far apart from each other along the line of best fit.
Therefore, from the given suggested points that Devon can draw a line, the most appropriate two points that would give a good line of best fit are points (6, 325) and (21, 200).
Try connecting these two points by drawing a line, you will discover that most of the data points represented fall along the line or and they are not much far apart from each other along the line.

Three high school basketball teams measured the heights of all of their basketball players: The Derby Dragons have a mean height of 72.0 inches and a standard deviation of 1.2. The Aviston Aces have a mean height of 70.8 inches and a standard deviation of 0.7. The Ballwin Bears have a mean height of 73 inches and a standard deviation of 1.0. On average, which team is a taller? Which team has players whose heights are more consistent? Select the correct answer below: The Derby Dragons are taller on average, and have players whose heights are more consistent. The Ballwin Bears are taller on average, and the Derby Dragons have players whose heights are more consistent. The Derby Dragons are taller on average, and the Ballwin Bears have players whose heights are more consistent. The Ballwin Bears are taller on average, and the Aviston Aces have players whose heights are more consistent.
Answer:
The Ballwin Bears are taller on average, and the Aviston Aces have players whose heights are more consistent.
Step-by-step explanation:
for derby dragon;
mean height = 72 inches
standard deviation = 1.2 inches
for aviston aces:
mean height = 70.8
standard deviation = 0.7 inches
for balwin bears;
mean height = 73 inches
standard deviation = 1.0 inches
the mean height of aviston aces < mean height of derby < mean height of balwin bears
So on average the balwin bears are taller.
The standard deviation of derby dragon is > that of balwin bears > aviston aces.
So the more consistent height is that of aviston aces players.

What do the following two equations represent?
6x-15y=15 and y=2/5x-1
Answer:
Same Line
Step-by-step explanation:
The solutions are all the same when both of them are asked to be solved. When you graph it, you get the same line, not intersecting, not perpendicular, its the same line.
Therefore the Answer is Same Line
The given two equations 6x - 15y = 15 and y = (2/5)x - 1 represent that both are identical to each other.
What is the equation?The equation is defined as a mathematical assertion with at least two terms that contain variables or integers that are equal.
We have been given two equations as
6x - 15y = 15 and y = 2/5x - 1
⇒ 6x - 15y = 15
Divided by 3 both sides of the equation
⇒ 2x - 5y = 5
⇒ y = 2/5x - 1
Multiply by 5 both sides of the equation
⇒ 2x - 5y = 5
When both of them are required to be solved, the answers are identical. When you graph it, you get the same line—not one that is perpendicular or intersecting—but just one that is.
As a result, the answer is identical.
