Suppose A has a coordinate of 8 and AB = 3. What are the possible midpoints of AB?
Answer:
The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].
Step-by-step explanation:
Let suppose that A and B have one-dimensional coordinates. GIven that [tex]A = 8[/tex] and [tex]AB = 3[/tex], there are two possible locations for B:
[tex]B_{1} = A+AB[/tex]
[tex]B_{1} =8+3[/tex]
[tex]B_{1} = 11[/tex]
[tex]B_{2} = A-AB[/tex]
[tex]B_{2} = 8-3[/tex]
[tex]B_{2} = 5[/tex]
The midpoint equations for each case are, respectively:
[tex]m_{1} = \frac{A+B_{1}}{2}[/tex]
[tex]m_{1}=\frac{8+11}{2}[/tex]
[tex]m_{1} = \frac{19}{2}[/tex]
[tex]m_{2} = \frac{A+B_{2}}{2}[/tex]
[tex]m_{2} = \frac{5+8}{2}[/tex]
[tex]m_{2} = \frac{13}{2}[/tex]
The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].

NEED IMMEDIATE HELP Water flows through a pipe at a rate of 6 fluid ounces per day. Express this rate of flow in cubic meters per year. Round your answer to the nearest hundredth.
Answer:
0.06 cubic meters per year...
Step-by-step explanation:
The rate of water flows through a pipe is 0.06 cubic meters per year.
What is rate of flow?It is the volume of fluid flows out from the container per unit time.
Given that,
Water flows through a pipe at a rate of 6 fluid ounces per day. It can be written as:
Water flows per day ⇔ 6 fluid ounces
∴ Water flows per year ⇔ 365 x (6 fluid ounces)
Volume of water in milliliter,
Water flows per year ⇔ 365 x (6 x 29.574 ml )
Volume of water in cubic meter,
Water flows per year ⇔ 365 x ([tex]\frac{6 x 29.574}{1000000}[/tex] [tex]m^{3}[/tex]) = 0.06477 [tex]m^{3}[/tex]
Hence Water flows per year round value to the nearest hundredth is 0.06 [tex]m^{3}[/tex].

What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that there are 82 people in a restaurant. Four groups of 3 leave and then five groups of 2 enter.
The expression will be solved as below:-
E = 82-12+10
E = 82+10-12
E = 92-12
E = 80
Therefore, the number of people in the restaurant will be 80

9 + 12m = 6 + 15(m - 1)
Answer: m=6
Step-by-step explanation:
[tex]9+12m=6+15\left(m-1\right)[/tex]
[tex]6+15\left(m-1\right)=15m-9[/tex]
[tex]9+12m=15m-9[/tex]
subtract 9 on both sides
[tex]9+12m-9=15m-9-9[/tex]
[tex]12m=15m-18[/tex]
subtract 15m on both sides
[tex]12m-15m=15m-18-15m[/tex]
[tex]-3m=-18[/tex]
divide by -3 on both sides
[tex]\frac{-3m}{-3}=\frac{-18}{-3}[/tex]

Pio
Answer:
(0, 6)
Step-by-step explanation:
Point T has a coordinate pair of (3, 4). That is, at point T, x = 3, while y = 4.
3 points to the left of T would be a movement on the x-axis. This movement is a run across the x-axis. At T, x = 3. Therefore, 3 points to the left would be a decrease by 3 = 3 - 3 = 0.
3 points to the left of T would leave us with an x coordinate of 0.
2 points above T suggest a rise, which is on the y-axis.
Therefore, at T, y = 4. 2 points above 4 = 4 + 2 = 6. y coordinate would now be 6.
In conclusion, the ordered pair representing 3 points to the left, and 2 points above point T is (0, 6).

Answer:
a) 820
b)450
c) -540
d) -294
e) 1440
f) 1425
Step-by-step explanation:
a) it is an arithmetic progression with ratio=4
a1=3,
a2=3+r=3+4=7.....
a20=a1+19r
so a20=3+19*4=3+76=79
S=(a1+an)*n/2 where n=20
so S=(3+79)*20/2=820
b) a15=a1+14*r=2+14*4=2+56=58
S=(a1+a15)*15/2=(2+58)*15/2=60*15/2=30*15=450
It is the same formula for all the exercises
S=(a1+an)*n/2 , where n is the number of terms
c) a40=30+39*(-3)=30-87=-57
So S=(30-57)*40/2=-540
d) a14=5+13*(-4)=5-52=-47
S=(5-47)*14/2=-42*14/2=-42*7=-294
e) it is 5+7+9+......+75
nr of terms = (an-a1) :r+1=(75-5):2+1=36
S=(5+75)*36/2=36*40=1440
f) ratio=7-4=3
the same formula for n= (91-4):3+1=87:3+1=29+1=30
S=(4+91)*30/2=95*30/2=2850/2=1425

How many numbers are 3 units from 0 on the real numbers line
Answer:
2 right? 3 and -3?
Step-by-step explanation:
Answer:
2 numbers
Step-by-step explanation:
● -3 and 3 are both 3 units apart from 0
We can find it with calculations.
You are moving in a real numbers line.
You can move either right or left.
You starting point is 0.
When you go 3 units to the right then you are adding 3.
● 3+0 = 3
When you go back 3 units starting from 0 then you are substracting 3.
● 0-3 = -3

Answer:
(- 1, 8 )
Step-by-step explanation:
Under a reflection in the line y = x

(8, - 1 ) → (- 1, 8 )
The image of (8, -1) after a reflection over the line y = x is, (- 1, 8).
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
We have to given that;

The image of point (x, y) after reflection over the line y = x is,
⇒ (x, y) → (y, x)
Thus, The image of (8, -1) after a reflection over the line y = x is,
