Find the value of X ?
Answer:
x = 19
Step-by-step explanation:
(10x - 23) and (7x + 34) are vertically opposite angles and congruent, so
10x - 23 = 7x + 34 (subtract 7x from both sides )
3x - 23 = 34 ( add 23 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19

26 out of 65 as a percentage
How would you do that without a calculator?
Answer:
40%
Step-by-step explanation:
you would first simply the fraction down
13 goes into both numbers so the fraction can be simplified to
2/5 which is think is simply enough to know that 2/5 is 40% but if not the explanation would be
100÷5 =20
20 x by the 2 from the fraction
= 40%
Step-by-step explanation:
65 = 100%
0.65 = 1%
26 = x%
x = (26 ÷ 0.65)%
x = 40%

Unit 4 Homework 2 Gina Wilson all things algebra,
Pls help!
Answer:
1. m∠1 = 48°
2. m∠1 = 129°
3. m∠1 = 37°
4. m∠1 = 88°
m∠2 = 42°
m∠3 = 113°
5. m∠1 = 72°
m∠2 = 35°
m∠3 = 24°
6. m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 133°
m∠5 = 81°
7. m∠1 = 41°
m∠2 = 85°
m∠3 = 95°
m∠4 = 85°
m∠5 = 36°
m∠6 = 49°
m∠7 = 106°
8. x = 12°
9. x = 9°
10. x = 5°
11. x = 7°
Step-by-step explanation:
1. 76° + 56° + m∠1 = 180°
∴ m∠1 = 180° - (76° + 56°) = 48°
m∠1 = 48°
2. m∠1 = 67° + 62° = 129°
m∠1 = 129°
3. m∠1 = 152° - 115° = 37°
m∠1 = 37°
4. m∠1 = 180° - (52° + 42°) = 88°
m∠1 = 88°
m∠2 = 42°
m∠3 = 180 - (42° + 25°) = 113°
m∠3 = 113°
5. m∠1 = 180° - 118° = 72°
m∠1 = 72°
m∠2 = 180° - 72° - 73° = 35°
m∠2 = 35°
m∠3 = 73° - 49° = 24°
m∠3 = 24°
6. m∠5 = 180° - m∠52° - m∠47° = 81°
m∠5 = 81°
m∠1 = 81° + 47° = 128°
m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 180° - 47° = 133°
m∠4 = 133°
7. m∠3 = 95°
m∠5 = 180° - 144° = 36°
m∠5 = 36°
m∠6 = 180° - 95° - 36° = 49°
m∠6 = 49°
m∠4 = 180° - 95° = 85°
m∠4 = 85°
m∠2 = 85°
m∠7 = 360° - (38° + 85° + (180° - 49°)) = 106°
m∠7 = 106°
m∠1 = 360° - (85° + 90° + 144°) = 41°
m∠1 = 41°
8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 16·x° - 12° = 180°
16·x = 180°+ 12° = 192°
x° = 192°/16 = 12°
x = 12°
9. (3·x - 5)° + (7·x + 5)° + 90 = 180°
10·x + 90° = 180°
10·x = 180°- 90° = 90°
10·x = 90°
x = 90°/10 = 9°
x = 9°
10. 180 - 151 = 29°
(11·x - 1)° + (20·x - 3)° + 29° = 180°
31·x° + 25° = 180°
31·x° = 180° - 25° = 155°
31·x° = 155°
x = 155/31 = 5°
x = 5°
12. (4·x + 13) + (6·x + 2) + 180 - (14·x - 13)
208° - 4·x° = 180°
208° - 180° = 4·x°
28° = 4·x°
4·x° = 28°
x = 28°/4 = 7°
x = 7°.

Answer:
1500.110 - 0.157x - 5.853x² ;
1124.262
Step-by-step explanation:
Given the data:
Price __ Sales

5 ___ 1353
7 ____ 1212
9 ____1025
11 ____790
13 ____509
Usibg the quadratic regression calculator :
1500.110 - 0.157x - 5.853x²
If ticket price = $8 each
Ticket sales will be :
y = 1500.110 - 0.157(8)- 5.853(8^2)

Virginia needed some batteries for her flashlights. She bought 4 batteries for $6.80. At that rate, how much would 10 batteries cost?
Answer:
$17
Step-by-step explanation:
First find the cost of 1 battery.
$6.80 ÷ 4 = $1.70
Then multiply the cost of one battery by 10.
$1.70 x 10 = $17
Answer:
10 batteries would cost $17
Cora is playing a game that involves flipping three coins at once let the random variable H be the number of coins that land showing heads. Here is the probability distribution for H.
Answer:
[tex]P(H <3) = 0.875[/tex]
Step-by-step explanation:
Given (Missing from the question):
[tex]\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}[/tex]
And the required question is:
Determine the P(H < 3)
P(H <3) implies that: P(H = 0) or P(H = 1) or P(H = 2)
So, we have:
[tex]P(H <3) = P(H = 0) + P(H = 1) + P(H = 2)[/tex]
[tex]P(H <3) = 0.125 + 0.375 +0.375[/tex]
[tex]P(H <3) = 0.875[/tex]

Angle ABD is 52°. State the size of angle DEB, giving a reason for your answer.
Answer:
∠ DEB = 52°
Step-by-step explanation:
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ DEB = ∠ ABD = 52°
The short answer is that you use the tangent-chord theorem. A more lengthy answer is given below.
=================================================
Explanation:
Refer to the diagram below.
I'm going to move point E so that segment EB becomes a diameter of the circle (it goes through the center point F). Points A,B,C,D will stay in place. The red points and red segments show the changes.
In this slightly redrawn diagram, triangle EDB is a right triangle where angle EDB is 90 degrees. This is due to Thales Theorem, which is a special case of the inscribed angle theorem.
Also, the new segment EB is perpendicular to segment AC because the diameter touching the point of tangency is perpendicular to the tangent line. So angle EBA is 90 degrees.
Since points A, D and B didn't move, this means angle ADB is still 52 degrees. This makes the new angle EBD equal to 90-52 = 38 degrees.
Despite the fact that angle E has moved, it has not effected the size of angle DEB. This angle is the same as its original because we're still subtending the same minor arc DB, and that arc hasn't changed size (since segment DB hasn't changed). So that's why it's valid to use the same x for the old angle DEB in black and the new angle DEB in red. They're the same angle.
-------------
Focus on triangle EBD. We have the following interior angles
B = 38D = 90E = xFor any triangle, the three interior angles must add to 180
B+D+E = 180
38+90+x = 180
128+x = 180
x = 180-128
x = 52
Angle DEB is 52 degrees
It's not a coincidence that we end up with the same angle as shown in the original diagram. The tangent-chord theorem says that the angle between a chord and tangent (as shown in the diagram) is exactly equal to the inscribed angle that subtends the arc formed by the chord. Arc DB is formed by chord DB.
In short, the tangent-chord theorem says that inscribed angle DEB and angle ABD are the same measure (both are 52 degrees).
This demonstration I've shown is one way to prove the tangent-chord theorem. Though a more rigorous proof would involve another variable.

An experiment consists of randomly selecting a marble from a bag, not replacing it, and then selecting another marble. The bag contains 3 yellow marbles and 2 white marbles. What is the probability of selecting a white marble and then a yellow marble?
Answer:
The bag contains 4 blue marbles, 3 green marbles, 7 red marbles, and 1 yellow marble. What is the probability of selecting a red marble and then a blue marble? Question 3 ... 4 blue marbles+ 3 green marbles+ 7 red marbles+ 1 yellow marble= 15 ... P(red,blue0 = 7/15 * 2/7 = 2/15 =.13333333 = 13.33%.
Step-by-step explanation:
Answer:
There are 14 total marbles. The probability of drawing a yellow marble on the first draw is 3/14. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of a black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

How do I write an equation for a line with a slope of ²/³ that has a y-intercept at -2.Titer eat at 2
Answer:
y = 2/3x - 2
Step-by-step explanation:
Given :
Slope, b = 2/3
y - intercept, c = - 2
The equation of a line can be expressed in slope intercept form as :
y = bx + c
b = slope ; c = y - intercept
Hence, line equation becomes ;
y = 2/3x - 2
