Katy works as a court reporter. She can type 27,000 words in two hours. Which of the following best represents Katy's rate in words per minute? *
Answers
Answer:
225 wpm
Step-by-step explanation:
Ok, I'm gonna solve it as I type this:
So you know that she types 27k words in two hours so you can divide it by 2 to get the words per hour. 27000 divided by 2 is equal to 13500 or also 13.5k.
Now you know the hours, you can divide that by 60 to get the words per minute since there are 60 words per hour.
You get 225 words. (That is a very fast speed lol I do 140)
So 225 words per minute.

Point slope question
Answers
Answer: (y + 3) = -1/3 (x - 2)
Step-by-step explanation:
Point-slope form has the form of
y - y1 = m (x - x1)
Where
y1 is the y-value of a point on the line
x1 is the x-value of a point on the line
m is the slope of the line
The problem already gives a point on the line, (2, -3)
(y + 3) = m (x - 2)
Remember to put the opposite value of the x and y values. (In other words, do NOT write (y - 3) = m (x + 2) )
The slope of a perpendicular line is the opposite reciprocal of slope of the line it is perpendicular to. The perpendicular line given in the equation is
3x - y = 4
When rearranged to slope-intercept form, we get
y = 3x - 4
Meaning the slope of the perpendicular line is 3. The opposite reciprocal of positive three is negative one-third. Therefore, the slope of the line we are solving for is -1/3.

In your own words, explain the steps you would need to take to find slope from data in a table. Brainly work your magic.
Answers
Answer:
In order to find the slope, you need to find the difference in the x values and the difference in the y values. To do this, you write out y2-y1/x2-x1, insert your x and y values, and get your answer. Then, you find your y-intercept (where the x value is 0).

There are 100 people in a sport centre. 67 people use the gym. 62 people use the swimming pool. 56 people use the track. 38 people use the gym and the pool. 31 people use the pool and the track. 33 people use the gym and the track. 16 people use all three facilities. A person is selected at random. What is the probability that this person uses at least 2 facilities?
Answers
Answer:
7/10
Step-by-step explanation:
For a person to use at least two of the facilities means they can use the three facilities as well.
Let n(U) be the total people in the sport centre = 100
n(G) be people that uses gym = 67
n(S) be people that uses swimming pool = 62
n(T) be people that uses track = 56
n(GnP) be gym and pool = 38
n(PnT) be people that use the pool and the track = 31
n(GnT) be people that use the gym and the track = 33
n(GnPnT) be people that use all three facilities = 16
People that uses gym and pool only = n(GnP) - n(GnPnT)
= 38-16
= 22
People that uses pool and track only = n(PnT) - n(GnPnT)
= 31-16
= 15
People that uses gym and track only = n(GnT) - n(GnPnT)
= 33-16
= 17
Total people that uses at least 2 facilities = 16+22+15+17 = 70
Probability that this person uses at least 2 facilities = Total people that uses at least 2 facilities/Total people in the sport centre
Probability that this person uses at least 2 facilities = 70/100 = 7/10

Step-by-step explanation:
Given A(-1,4), B(2,-5), and C(3, 4), which coordinate pair will make AB perpendicular to CD ?
Answers
Answer:
The coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3)
Step-by-step explanation:
The slope of the given line AB can be presented as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m =\dfrac{-5-4}{2-(-1)} = \dfrac{-9}{3} =-3[/tex]
The slope of a perpendicular line to a given line is equal to the negative reciprocal of the slope of the given line
Therefore, the slope of the perpendicular to a line that has a slope of m is -1/m
The slope of the perpendicular to the line AB is therefore [tex]-\dfrac{1}{3}[/tex]
From which we get the equation of the perpendicular to the line AB given as follows;
y - 4 = -1/3 × (x - 3)
y - 4 = -x/3 + 1
y = -x/3 + 1 + 4
y = -x/3 + 5
When x = 6, y = -6/3 + 5 = 3
Therefore, the coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3).
Using the slope concept, it is found that the coordinate pair is:
[tex]D\left(x, \frac{x}{3}+9\right)[/tex]
The slope of a coordinate pair [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the change in y divided by the change in x, that is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
If two segments are perpendicular, the multiplication of their slopes is -1.
For segment AB, the slope is:
[tex]m = \frac{-5 - 4}{2 - (-1)} = -\frac{9}{3} = -3[/tex]
At segment CD, we want that:
[tex]-3m = -1[/tex]
[tex]m = \frac{1}{3}[/tex]
Considering D(x,y), we have that:
[tex]\frac{y - 4}{x - 3} = \frac{1}{3}[/tex]
Writing y as a function of x:
[tex]x - 3 = 3(y - 4)[/tex]
[tex]3y - 12 = x - 3[/tex]
[tex]3y = x + 9[/tex]
[tex]y = \frac{x}{3} + 9[/tex]
Thus, the coordinate pair is:
[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order?
Answers
Answer:
110 pounds of peaches should be ordered
Step-by-step explanation:
Here, we want to calculate the number of pounds of peaches to order.
Let the number of peaches to ordered be x peaches
Now, since 9% is expected to be bad, then the percentage expected to be good will be 91%
Thus;
91% of x = 100
91/100 * x = 100
91x = 100 * 100
x = 10000/91
x = 109.89
Since we cannot have fractional peaches, then x must be 110

Next, we must divide all sides by -3, so y=-2/-3x-3
Finally, simplify the equation to y=2/3x-3
Answer:
y=mx+b
y=2/3x + -3

Step-by-step explanation:

subtract 2x from each side leaving it -3y = -2x +9
now divide both sides by -3 -3y/-3=-2x/-3 +9/-3
y= 2/3+ -3

Answer:
$6.13 for each basket.
Bonus: $61.30 for ten baskets.
Step-by-step explanation:
To solve this, we would divide the $24.50 by four, because there are four baskets. We now know that she paid $6.13 (rounded from $6.125) for each basket. To solve for 10 baskets, you would take the price per basket of $6.13 and multiply it by ten, resulting in $61.30 for all ten baskets.
