Answer: (13.5 , 8)
14 + 13 / 2 = 13.5
14 + 2 / 2 = 8
Answer:
(13.5,8)
Step-by-step explanation:
midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]
[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

I need help! ABCD is a rectangle.
m<1 =
m<6 =
m<3 =
Answer:
m∠1 = 24°
m∠3 = 66°
m∠6 = 66°
Step-by-step explanation:
They are all near the corners of the rectangle
The corners always equal 90°
But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°
Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.
m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So
90 - 24 = 66
So both m∠3 and m∠6 = 66°

Quadrilateral BCDE is inscribed in circle A. The measure of ⏜ is 73°. The measure of ⏜ is 53° and the measure of ⏜ is 102°.
Determine the measure of ∠ BCD.
Answer:
117
Step-by-step explanation:
Angle BCD intercepted arc is Arc DEB.
We know DE measure but we need to find EB measure.
Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.
[tex]73 + 53 + 102 + x = 360[/tex]
[tex]126 + 102 + x = 360[/tex]
[tex]228 + x = 360[/tex]
[tex]x = 132[/tex]
So arc EB measure 132.
Arc eb and de.
132+102=234.
Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.
[tex] \frac{234}{2} = 117[/tex]
4. For which of the following probability assignments are events A and B independent?
P(AN B“) – 0.3. P(AN B) = 0.12, and P(Aºn B) = 0.4.
B
P(An BC) = 0.3. P(An B) = 0.3, and P(Aºn B) = 0.3.
C) P(An Bº) = 0.1. P(ANB) = 0.1, and P(Aº n B) = 0.4.
P(An Bº) = 0.3. P (AnB) = 0.0, and P(
AB) = 0.2.
E) P(An Bº) = 0.5, P (ANB) = 0.1 and P (Aºn B) = 0.4
Answer:
A
Step-by-step explanation:
formatting is so bad lol
but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12
Given the equation y= -3x + 2.5 . When y is 8.5 , what value of x makes the equation true?
Answer:
x = -2
Step-by-step explanation:
y = -3x + 2.5
if y = 8.5 then:
8.5 = -3x + 2.5
-3x = 6
x = -2
If you have 4 red, 3 blue, and 5 green M&Ms and draw an M&M at random, what is the probability of the following. Write your answer as a fraction, decimal, and percent.
1. Red M&M
2. Green M&M
3. Green or Blue M&M
Answer:
1. 0.3333333
2. 0.4166666
3. 0.6666666
Step-by-step explanation:
add them all up for a total of 12. then divide 4 into 12 for the probability of number 1. Next, divide 5 into 12 for the probability of green. Finally, add 3 and 5 to get 8 and divide by 12.
Can someone plzzz helppp meeee!!!!!!!!
Answer:
Radius of the Inner circle:
5.4 is the diameter so find the radius, divide by 2 = 2.7
Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.
3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.
Radius of Outer circle:
2.2 is the diameter so find the radius, divide by 2 = 1.1
Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.
3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.
Radius of the Inner circle: 23
Radius of Outer circle: 4
Please let me know if it was correct!
Identify the vertex of the parabola and tell whether it is a minimum or a maximum.
Answer:
First parabola's vertex is (-2,2), which is a minimum.
Second parabola's vertex is (3,2), which is a maximum.
Step-by-step explanation:
Simply, a vertex of a quadratic is a graph's turning point.
The maximum and minimum can be identified by seeing if the graph curves up or down.
Maximum occurs when your graph is facing down.
Minimum occurs when your graph is facing up.
Please help!!!!!!!! Find radius and diameter. will mark brainiest!!!!!!!!!!
Answer:
The radius is given its 10 in
The diameter is 20 in
Step-by-step explanation:
Two find the diameter given the radius you just multiply by 2
10x2=20 therefore the diameter is 20
Hope this helps :)
Answer:
Radius = 10 inches. Diameter = 20 inches
Step-by-step explanation:
Radius is the halfway point in a circle, the line which says 10 inches. While the diameter is the full length across the circle, which would be the radius times itself, 20.
Hope this helps!

Does 514, 684, 855 make a right triangle
Answer:
No, it does not.
Step-by-step explanation:
This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.
For example:
900, 800, 900 makes a right triangle
900, 800, 700 does not.

3w - 10>-4
Answer:
If your trying to find w then it'll be 2
Step-by-step explanation:
3w - 10 > -4
+10 +10
3w > 6
3 3
w > 2
So I added 10 on both sides and guess positive 10 is bigger than -4, it'll be a positive 6. Then I divide 3 on both sides after I got 6 and thats how I got 2
A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.
Answer:
P = 60
Step-by-step explanation:
First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.
25 5
---- = ----
15 3
So the larger triangle is 5/3 times bigger.
This means that all of its other sides with also be 5/3 times bigger.
So:
9 (5/3) = 45/3 = 15
12 (5/3) = 60/3 = 20
25 + 15 + 20 = 60
So the perimeter is 60.
You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:
36 (5/3) = 180/3 = 60
You would get the same thing.
