Answer:
You are correct it is 12.
Step-by-step explanation:
Answer: Square root of 288, or estimated 16.97
Step-by-step explanation:
Conveniently, the points form a diagonal line as you show, so we can use the Pythagorean Theorem to find the distance.
The x-component of this is the distance between -6 and 6, which is 12, and the y-component is again the distance between -6 and 6, which is also 12.
Therefore, the distance is the square root of 12^2 + 12^2, or the squareroot of 288.

If the ratio of cars to trucks on the lot is 11 to 33 and there are currently 51 trucks for sale, then there are 17 cars for sale
The ratio of cars to truck on the lot = 11 : 33
Total number of trucks for sale = 51 truck
Consider the number of cars for sale = x
Then the ratios will be
11/33 = x / 51
Cross multiply the terms in the equation
33x = 51 × 11
33x = 561
Move 33 to the right hand side of the equation
x = 561 / 33
Divide the terms
x = 17
Therefore, the number of cars does the dealer have for sale is 17

A metal washer has an external diameter of 2 cm and an internal diameter of 1 cm.
How many washers can be cut from a sheet of steel 3 m by 1 m?
If the metal left over was remelted and cast into a sheet of the same thickness and
width 1 m, how many additional washers could be cut?
(a) The number of washers that can be cut from a sheet of steel is 12,732 washers.
(b) No additional washers could be cut from the metal left over after it was remelted and cast into a sheet of the same thickness and width (1 m).
How many washers can be cut from the sheet?
First, we need to calculate the area of the washer, which can be done as follows:
Area = π (de/2)² - π (di/2)²
= π(0.02 m/2)² - π (0.01 m/2)²
= 0.000236 m²
Now, we can calculate the number of washers that can be cut from a 3m x 1m sheet of steel:
Number of washers = (Area of the sheet) / (Area of the washer)
= (3 m x 1 m) / 0.000236 m²
= 12,732 washers
Next, we need to find the area of the metal left over after cutting the 12,732 washers. This can be calculated as follows:
Area of the metal left over = (3 m²) - (12,732 x 0.000236 m²)
= 3 - 3.05
= -0.05 m²
Since the metal left over is negative, it means that not enough metal was available to cut 12,732washers. Hence, 12,732 is the maximum number of washers that can be cut from a 3m x 1m sheet of steel.

The expression that represents the amount of money the friends still need to collect to meet their goal is 5x² - 7xy + 20. The solution has been obtained by using arithmetic operations.
What are arithmetic operations?
The four fundamental mathematical operations that can be used to express any real number are referred to as "arithmetic operations" in mathematics. The four operations are addition, subtraction, division, and multiplication.
We are given the total contribution goal as 8x² - 4xy + 9
Amounts collected by:
Martin = 3xy + 17
Tyreese = x²
Braydon = 2x² - 6
So, the total amount collected till now is
(3xy + 17) + x² + (2x² - 6) = 3x² + 3xy - 11
Amount left to be collected is
⇒(8x² - 4xy + 9) - (3x² + 3xy - 11)

How much water was already in the pool when the hose was turned on today?
gallons
Complete the equation to represent the relationship between the volume of water in the pool in gallons, V, and the elapsed time in hours, t, since the hose was turned on today.
QUIC HELP
1) Note that the volume of water that was already in the pool when the hose was turned on today is 2000 gallons of water.
2) The equation that represents the relationship between the volume of water in the pool in gallons "V) and the elapsed time in hours, t, since the hose was turned on today is V = 800t + 2000.
Note that to get the right expression above we have to solve for the slope of the graph.
What is the rationale for the above response?1) To arrive at the answer in 1 above, we only have to examine the y-intercept. since at time (t) =0 the volume of water (gallons) indicated on the graph is 2000 gallons, thus, it is correct to state that:
"the volume of water that was already in the pool when the hose was turned on today is 2000 gallons of water."
2) From the graph, we can see the equation must be linear.
That is:
y = mx + b
Where y = V = Volume of Water in the Pool in Gallons
m = Slope
x = t = elapsed time in hours
b = y- intercept = already given as 2000
Thus:
To get m (slope) we need to use the above equation:
m = rise/run = y2-y1/x2-x1
Take
y1 = 6000
y2 = 10,000
x1 = 5
x2 = 10
Substituting the given values, we get:
m = (10,000 - 6,000) / (10 - 5)
m = 4,000 / 5
m = 800
Therefore, the slope of the line passing through the points (5, 6000) and (10, 10,000) is 800.
Having derived m, the full expression is thus given as:
V = 800t + 2000.

What is the complete square corresponding to x2 – 6x? A. (x – 1.5)2 B. (x – 3)2 C. (x – 4.5)2 D. (x – 9)
Answer:
So the answer is C. (x - 3)^2.
Step-by-step explanation:
The complete square corresponding to x^2 - 6x is (x - 3)^2.
A complete square is a trinomial that can be written in the form (x - a)^2, where a is a constant. To find the complete square of x^2 - 6x, we need to rewrite x^2 - 6x into the form (x - a)^2. We do this by adding and subtracting a constant term to make the trinomial a perfect square.
x^2 - 6x + 9 = (x - 3)^2
So the answer is C. (x - 3)^2.
Determine the intercepts of the line. Do not round your answers. y+1=3(x − 4) x-intercept: (_,_) y-intercept: (_,_)
The intercepts of the line are x intercept: (4.3,0) y-intercept: (0,-13)
How to determine the intercepts of the lineFrom the question, we have the following parameters that can be used in our computation:
y+1=3(x − 4)
To calculate the x-intercept, we set y to 0
So, we have the following representation
0+1=3(x − 4)
This gives
x - 4 = 1/3
So, we have
x = 4.33
To calculate the y-intercept, we set x to 0
So, we have the following representation
y + 1 = 3(0 − 4)
This gives
y + 1 = -12
So, we have
y = -13

Can someone help me find the point of intersection for:
2500(1. 25)^t=6000(0. 3)^t
algebraically? thank you.
The point of intersection can be found by setting the equations equal, dividing by the same quantity, taking the natural log, and dividing by ln(1.25).
[tex]2500(1.25^t) = 6000(0.3^t)[/tex]
[tex]2500*1.25^t = 6000*0.3^t[/tex]
Divide both sides by 2500:
[tex]1.25^t = 0.3^t * (6000/2500)[/tex]
Divide both sides by[tex]0.3^t[/tex]:
[tex]1.25^t / 0.3^t = (6000/2500) / 0.3^t[/tex]
Take the natural log of both sides:
[tex]t*ln(1.25) = ln((6000/2500) / 0.3^t)[/tex]
Divide both sides by ln(1.25):
[tex]t = ln((6000/2500) / 0.3^t) / ln(1.25)[/tex]
The point of intersection is t = ln((6000/2500) / [tex]0.3^t[/tex]) / ln(1.25).
The point of intersection of two exponential functions can be found algebraically by setting the two equations equal to each other and solving for the variable t. For example, if we want to find the point of intersection of [tex]2500(1.25^t) = 6000(0.3^t)[/tex], we can start by setting the two equations equal to each other and dividing both sides by [tex]2500: 1.25^t = 0.3^t * (6000/2500)[/tex]. Then we can divide both sides by[tex]0.3^t: 1.25^t / 0.3^t = (6000/2500) / 0.3^t[/tex]. We then take the natural log of both sides: [tex]t*ln(1.25) = ln((6000/2500) / 0.3^t)[/tex]. Finally, we divide both sides by ln(1.25): [tex]t = ln((6000/2500) / 0.3^t) / ln(1.25)[/tex]. This means that the point of intersection is[tex]t = ln((6000/2500) / 0.3^t) / ln(1.25).[/tex] In conclusion, the point of intersection of two exponential functions can be found algebraically by setting the two equations equal to each other, dividing both sides by the same quantity, taking the natural log of both sides, and then dividing both sides by ln(1.25).

8. the weights of cows offered at an auction in one region are normally distributed with a mean of 825.0 pounds and a standard deviation of 74.8 pounds. one cattleman only wants to bid on cows that are in the top 5% of weight. what is the lowest weight cow that the cattleman should bid on
The cattleman should bid on cows that weigh at least 944.0 pounds, which is the weight corresponding to the top 5% of the normally distributed weights of cows.
To determine the lowest weight cow that the cattleman should bid on, we need to find the weight that corresponds to the top 5% of the weight distribution.
Using the standard normal distribution, we can find the z-score that corresponds to the top 5% of the distribution as follows:
z = invNorm(0.95) ≈ 1.645
where invNorm is the inverse of the standard normal cumulative distribution function, which can be found using a statistical calculator or a standard normal distribution table.
Next, we can use the z-score formula to convert the z-score to a weight value:
z = (x - μ) / σ
Solving for x, we get:
x = z * σ + μ
Substituting the values given in the problem, we get:
x = 1.645 * 74.8 + 825.0
x ≈ 944.0 pounds
Therefore, the cattleman should bid on cows that weigh at least 944.0 pounds.

Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
From the given information,
Slope(m) = (42 - 48)/(5 - 0).
