I think it's C but I might be
Step-by-step explanation:
The midpoint of AD is C. The midpoint of AC is B. If A is at (-10,4) and D is at (2,12), find the coordinates of B. Group of answer choices (-5,5) (-4,8) (-2.5,9) (7,6)
Answer:
[tex]B(x,y) =(-7,6)[/tex]
Step-by-step explanation:
Given
[tex]A = (-10,4)[/tex]
[tex]D = (2,12)[/tex]
Required
Determine the coordinates of B
C is the midpoint of AD. So, we calculate the coordinates of C, first.
[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Where:
[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]D = (2,12)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]C(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
[tex]C(x,y) = (\frac{-10+2}{2},\frac{4+12}{2})[/tex]
[tex]C(x,y) = (\frac{-8}{2},\frac{16}{2})[/tex]
[tex]C(x,y) = (-4,8)[/tex]
So, the coordinates of C is (-4,8)
The midpoint of AC is B.
So, we calculate the coordinates of B using:
[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Where:
[tex]A = (-10,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]C(x,y) = (-4,8)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]B(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
[tex]B(x,y) =(\frac{-10-4}{2},\frac{4+8}{2})[/tex]
[tex]B(x,y) =(\frac{-14}{2},\frac{12}{2})[/tex]
[tex]B(x,y) =(-7,6)[/tex]
Hence, the coordinates of B is (-7,6)
None of the options is correct.

A movie theater has a seating capacity of 385. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 2794, How many children, students, and adults attended?
Answer:
Step-by-step explanation:
The number of children is 198, adults are 99 and students are 88.
What is word problem?A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
Given that, the theatre sitting capacity is 385 and the theatre charges are $5.00 for children $7.00 for students, and $12.00 for adults.
Let the number of children be c, since, there are half as many adults as there are children therefore, number of adults = c/2
The number of students = 385 - c - c/2 = 385 - 3c/2
The total cost = $2794
Therefore,
2794 = 5c+c/2×12+(385-3c/2)×7
2794 = 5c+6c+2695 - 21c/2
c = 198
Therefore, number of adults = 198/2 = 99
The number of students = 385-3/2×198 = 88
Hence, The number of children is 198, adults are 99 and students are 88.

Find midpoint of PQ with endpoints P (0,2) and Q (6,-2)
Answer:
(3, 0)
Step-by-step explanation:
The easiest way to do this problem is to average the x-coordinates and y-coordinates.
So, (0 + 6) / 2 = 6/2 = 3 = x and (2 - 2)/2 = 0/2 = 0 = y
Therefore, the midpoint is (3,0)

A single card is drawn from a deck. Find the probability of selecting a 4 or diamond
Answer:
I believe 16/52
Step-by-step explanation:
There are 13 diamonds and 4 fours. Add those together then you get 17/52. It is not that since there is a four of diamonds card, so you would need to subtract one. Then that reduces to 4/13
Which graph represents the function f(x) = 4x
Answer:
[tex]\boxed{\textsf{ The required graph of y = 4x will be a straight line passing through the origin . }}[/tex]
Step-by-step explanation:
Here we need to plot the graph for the function given to us . The function is ,
[tex]\sf \implies f(x)= 4x [/tex]
In order to plot a graph let us assume that ,
[tex]\sf\implies y = f(x) [/tex]
Hence we now get , that ,
[tex]\sf\implies y = 4x [/tex]
Now let's find out some values of x and y taking which we will plot the graph .
• So , firstly let , x = 0 then y will be equal to 4*0 = 0 . Hence we got one coordinates as (0,0) .
• Secondly let x = 1 , then y will be equal to 4*1 = 4 . Hence we get the third coordinate as (4,0) .
• Thirdly let us take that x = 0.5 then y will be equal to 4*0.5 = 2 . Hence we got the third coordinate as ( 0.5 , 2 )
• Fourthly let x = -0.5 then y will be equal to 4*-0.5 = -2 . Hence the fourth coordinate will be (-0.5 , -2)
Now when we plot it's graph taking suitable scale then it will look something like that as shown in attachment .
For the graph of y = 4x kindly refer to the attachment :) .

Herb’s mom is a seamstress. She hems shirts, pants and dresses. For each item she hems she gets paid $1.50. If she hems 45 pieces of clothing each day, how much money would she make after working 30 days?
a.) $2,025
b.) $135
c.) $67.50
Answer: $2025
Step-by-step explanation:
$1.50. x 45= 67.5 items per day. 30 days is 30 x 67.5= $2025
Answer:
a) $2025
Step-by-step explanation:
The equation you would do is
[tex](45(1.50))30[/tex]
by multiplying 45 and 1.50, you get the price of how much money she makes after one day. in order to find 30 days, just take the product of that equation and multiply it by 30 to get $2025
