What is the measure of x and what is the reasoning you used
Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108

The vertices of a quadrilateral in the coordinate plane are known. How can the perimeter of the figure be found?
A) Use the distance formula to find the length of each side, and then add the lengths.
B) Use the slope formula to find the slope of each side, and then determine if the opposite sides are parallel.
C) Use the slope formula to find the slope of each side, and then determine if the consecutive sides are perpendicular.
D) Use the distance formula to find the length of the sides, and then multiply two of the side lengths.
A) Use the distance formula to find the length of each side, and then add the lengths.
-18 = 9z - 9
z =___?
Answer:
z = - 1
Step-by-step explanation:
Given
- 18 = 9z - 9 ( add 9 to both sides )
- 9 = 9z ( divide both sides by 9 )
- 1 = z

The area of a rectangle is 12x^2 - 8x - 15. The width is (2x - 3). What is the length of the
rectangle?
Answer:
6x+5 us the length of the rectangle
Step-by-step explanation:
If A = 12x² - 8x - 15 and w = 2x - 3, then..
l = (12x² - 8x - 15)/(2x - 3)
= (2x - 3)(6x + 5)/(2x - 3)
= 6x + 5 cm
Sally has 8 red marbles and 16 green
marbles. She also has red bags and
green bags. She wants to put marbles in
the bags that match their color. Each
bag will have the same number of
marbles. What is the largest number of
marbles she can put into each bag?
Answer: 8
Step-by-step explanation: It's just GCF. The greatest common factor (GCF) of 8 and 16 is 8 (8 and 16 are both divisible by 8 but not by anything greater) which brings us to our answer.

find the value of x and y
Answer:
It's hard to make out which is x and y, if x is lower right and y is at the top, then:
x = 55°
y = 70°
Step-by-step explanation:
x = 55° because it is an isosceles triangle
y = 180° - 55° - 55° = 70°

find the solution of the system of linear equations below
y = 5x +1
–5x + y = 1
Answer:
Infinite number of solutions.
Step-by-step explanation:
Y=5x+1
-5x+Y=1
substitute value of y in first equation (5x+1) into 2nd equation
-5x+5x+1=1
0+1=1
1=1
since answer equals on both sides of the equatio, the answer is determined to be infinite.

compute the distance between (9,-5,4) and (-10,3,4)
Answer:
~20.6155
Step-by-step explanation:
To compute distance between two points, we can get the vector from one to the other by subtracting them and then computing the length of the vector.
The length of a vector V is:
[tex]|V| = \sqrt{\sum_{i=1}^n v_i^2}\\[/tex]
The vector is:
(9, -5. 4) - (-10, 3, 4) = (9 + 10, -5 - 3, 4 - 4) = (19, -8, 0)
So the length is:
[tex]\sqrt{19^2 + (-8)^2} = \sqrt{361 + 64} = \sqrt{425} = \sqrt{5\cdot 5\cdot 17} = 5\sqrt{17} \approx 20.6155281281[/tex]

29°
X
(Round to the nearest whole number as needed.)
Answer:
x = 557 to the nearest whole number
Step-by-step explanation:
The triangle is divided into two right triangles
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 29 = (x/2)/502
x/2 = 502 tan 29'
x/2 = 278.26
x = 278.26 * 2
x = 556.52
x = 557 to the nearest whole number
Use point slope form to write the equation of a line slope intercept form that passes through the points 0,-5 and -3,4
Answer:
y + 5 = -3(x - 0)
Step-by-step explanation:
First, you find the slope. To do that, you subtract the second y point (in this case 4) by the first y point (in this case -5), and you get 9. Then, you subtract the second x point (in this case -3) by the first x point (in this case 0), and you get -3. Y is over X, so you get 9/-3 or 9 over -3, which can simplify to -3.
Next, you use the point slope formula: y - y1 = m(x - x1). Add in the y1, m, and x1, then solve if it asks you to put it in slope intercept form. So, for this case, it would be y + 5 = -3(x - 0)
Yay!!!! :D
Find mHT
A) 140°
C) 145°
B) 150°
D) 120°
Answer:
A
Step-by-step explanation:
The secant- secant angle is half the difference of the intercepted arcs, then
[tex]\frac{1}{2}[/tex] (20x - 7x - 11) = 40 ( multiply both sides by 2 to clear the fraction )
13x - 11 = 80 ( add 11 to both sides )
13x = 91 ( divide both sides by 13 )
x = 7
Then
arc HD = 20x = 20 × 7 = 140° → A

Tarzan split up $21 equally among 30 winners. What decimal is equivalent to the fraction of a dollar that each winner received? Round to hundredths.
Answer:
21/30 = 7/10 = 0.7
Step-by-step explanation:
spliting up 21 dollars among 30 winners, is dividing 21 by 30. When you do this you can simplify it to 21/30 = 7/10. 7/10 is equal to 0.7.
Answer:
$0.7
Step-by-step explanation:
As you may know, instead of saying divide. You can say split. So $21 split between 30 people would be $0.7 or 70 cents.
2. What is the measure of angle AOE and angle EOD?
X+138
x + 48
Answer:
AOE = 138, EOD = 48
Step-by-step explanation:
Since AD is the diameter of the circle and goes through the middle
angle AOE + angle EOD = 180
Solving the equation (x + 138) + ( x+ 48) = 180
We get x = 0.

A bag contains six white marbles and four black marbles a marble is drawn from the bag and then a second marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw polo buy a black marble on the second?
Answer:
4/15
Step-by-step explanation:
Total event: 6+4=10
First draw: 6 white out of 10 marbles 6/10
2nd draw: 4 black out of 9 marbles 4/9
probability of drawing a white marble on the first draw polo buy a black marble on the second: 6/10 x 4/9 = 4/15
