Find the coordinates of the midpoint of the segment whose endpoints are H (-4, 10) and K (2,-4)
9514 1404 393
Answer:
(-1, 3)
Step-by-step explanation:
The midpoint is the average of the end points.
M = (H +K)/2
M = ((-4, 10) +(2, -4))/2 = (-4+2, 10-4)/2 = (-2, 6)/2
M = (-1, 3)
The coordinates of the midpoint are (-1, 3).

9. If NK = 7x-1, NM = 10x - 13, and KM = 24, find NP.
Answer:
[tex]NP = 24.18[/tex]
Step-by-step explanation:
Given
[tex]NK = 7x - 1[/tex]
[tex]NM = 10x - 13[/tex]
[tex]KM = 24[/tex]
See attachment
Required
Length of NP
First, calculate the value of x
[tex]NK = NM[/tex]
So:
[tex]7x -1 = 10x - 13[/tex]
Collect like terms
[tex]10x - 7x = 13 - 1[/tex]
[tex]3x =12[/tex]
Solve for x
[tex]x = 4[/tex]
To solve for NP, we consider right triangle [tex]\triangle NKP[/tex]
Where
[tex]NK = 7x - 1[/tex]
[tex]NK = 7 * 4 - 1[/tex]
[tex]NK = 27[/tex]
[tex]KP =\frac{1}{2}KM[/tex]
[tex]KP =\frac{1}{2} * 24[/tex]
[tex]KP =12\\[/tex]
Using Pythagoras theorem, we have:
[tex]NK^2 = KP^2 + NP^2[/tex]
[tex]27^2 = 12^2 + NP^2[/tex]
[tex]729 = 144 + NP^2[/tex]
Collect like terms
[tex]NP^2 = 729 - 144[/tex]
[tex]NP^2 = 585[/tex]
Take square roots
[tex]NP = \sqrt{585[/tex]
[tex]NP = 24.18[/tex]
16/4 + 56 – (3 + 4 - 1)
Answer:
54
Step-by-step explanation:
First solve for brackets then multiplication or division then addition or subtraction
Answer: 52.
Step-by-step explanation: I don't know if you know about PEMDAS, but it basically stands for (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). So first, we would do Parenthesis. In the parenthesis, we have 3 + 4 - 1. Addition and Subtraction are the same, since they are inverse operations. We would start from left to right, so the addition goes first. 3 + 4 = 7. Now we are left with 7 - 1. 7 - 1 = 6. The equation so far is: 16/4 + 54 - 6. Next, we will do division. 16 ÷ 4 = 4. The equation so far is: 4 + 54 - 6. Now, we have to add 4 + 54 since we are doing it from left and right. 54 + 4 = 58. We are left with 58 - 6. 58 - 6 = 52. So your final answer is 52. Hope this helps!! :) **I tried my best**

-2x + 7y = 20
x + 7y = 32
Answer:
(4,4)
Step-by-step explanation:
1) Using substitution: move 7y to the other side by subtraction
x = 32 - 7y
2) substitute in for x in the first equation
-2(32 - 7y) + 7y = 20
3) distribute
-64 + 14y + 7y = 20
4) add like terms and solve for y
21y = 84
y = 4
5) plug in y value of for in one of the eqautions to get x value
-2x + 7(4) = 20
x = 4

Answer:
mean: 4
median: 5
mode: 5
Step-by-step explanation:
Hi there!
Let's first start with the mean
the mean is the average of all of the numbers; we add up how many hours each week each student spent playing video games and then divide it by how many people responded (9)
(0+5+7+5+3+0+9+5+2)/9
add all of the numbers on top
36/9
divide
4
the mean is 4
now find the median, or the value that separates the upper half from the lower half of the data (it's the "center" value).
first, list the numbers in order from least to greatest
0,0,2,3,5,5,5,7,9
now get rid of the largest number and the smallest number (0 and 9)
the set is now:
0,2,3,5,5,5,7
now get rid of the largest and smallest number in the new set (0 and 2)
the set becomes:
2,3,5,5,5
get rid of the largest and smallest number in the new set (2 and 5)
3,5,5
get rid of the largest and smallest number in the new set (3 and 5)
5
the median is therefore 5
the mode is the number that occurs most frequently in the data set
here's our list again of all of the numbers from least to greatest:
0,0,2,3,5,5,5,7,9
we can count how many times each number appears to find the mode
0: 2 times
2: 1 time
3: 1 time
5: 3 times
7: 1 time
9: 1 time
since 5 appeared the most times, then the mode is 5
hope this helps!

Answer:
x = 11
Step-by-step explanation:
[tex]x-3y=-7[/tex]
[tex]5x=-2y+67[/tex]
=> [tex]x=\frac{1}{5}(-2y+67)[/tex]
=> [tex]x=-\frac{2}{5}y+\frac{67}{5}[/tex]
=> [tex]-\frac{2}{5}y+\frac{67}{5}-3y=-7[/tex]
=> [tex]-\frac{17}{5}y+\frac{67}{5} =-7[/tex]
=> [tex]\frac{-17}{5}y=-\frac{102}{5}[/tex]

in how many years 1600 invested at 5% will amount to 1920
Answer:
principal=1600
rate=5%
amount=1920
time=x
interest=p*t*r/100
=1600*x*5/100
=8000x/100
80x
amount=principal +interest
1920=1600+80x
1920-1600=80x
320/80=x
4=x
therefore after 5 years 1600 amount to 1920 at the rate of 5%

What is an Inscribed Angle ?An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
In the circle, the two lines AC and AD intersect outside the circle at the point A .
m∠CAE=1/2(m CD−m BE)
The formula for the angle between 2 secants is
1/2 (124 - 16)
= 1/2 * 108
= 54°
Therefore the measure of CA = 54°

Answer:
∠ h = 75°
Step-by-step explanation:
∠ e = ∠ a = 105° ( corresponding angles )
∠ h and ∠ e are adjacent angles and sum to 180°
∠ h + 105° = 180° ( subtract 105° from both sides )
