Find the value of c. 16 = 4 - 3c
Answer:
c = -4
Step-by-step explanation:
16 = 4 - 3c
subtract 4 from each side
16-4 = 4-4 - 3c
12 = -3c
Divide each side by -3
12/-3 = -3c/-3
-4 =c

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? *
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.
Given A(-1,4), B(2,-5), and C(3, 4), which coordinate pair will make AB perpendicular to CD ?
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]

Is the square root of 15 greater than, less then , or equal to 4?
Answer:
less than 4
Step-by-step explanation:
the closest perfect square root to 15 is the square root of 16, which produces the number 4. since 16 is greater than 15, the value of the square root of 15 is less than 4.

At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The number of food tickets sold was 10 less than twice the number of ride tickets sold.
The system of equations represents x, the number of food tickets sold, and y, the number of ride tickets sold.
2x + 3y = 1240
x = 2y – 10

In your own words, explain the steps you would need to take to find slope from data in a table. Brainly work your magic.
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).
Answer:
Sample Answer
Step-by-step explanation:
Start by choosing two data points. Calculate the difference between the second y value and the first y value. Then divide that by the difference between the second x value and the first x value.

How many degrees does the minute hand of a clock travel in 1 minute? What angle does an hour hand travel in 1 min?
Answer:
6° and acute angle
you watch the clock or find a clock, in right angle there 90° or 3 o'clock, if you want to understand it, try to count the the minute from 12 to 3 in the clock, if you count it then you see the are there is 15 minutes, then the 90° divide the number of minute which is 15, the answer is 6°. and then the answer of the next question is acute angle it is because the hour hand of the clock travels in 1 minute, it means every 1minute there are 6°, and 6° is less than 90° that why it's acute angle.
Emy paid 24.50 for 4 baskets of apples. How much did she pay for each basket?
Bonus: How much will it be for 10 baskets.
Please help me it will be very much appreciated!
Due in one hour.
Answer:
6.125
Step-by-step explanation:
Divide 24.50 by 4!
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.

can someone please help me and explain how to change 2x − 3y = 9
into slope intercept form
Answer:
y=2/3x-3
Step-by-step explanation:
first, you have to isolate the y, so subtract 2x from both sides. -3y=-2x+9
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
2/3 is the slope points are (0,-3)
Step-by-step explanation:
2x-3y =9
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
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?
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
