Answer:
x=8°
y= 96°
z= 96°
Step-by-step explanation:
Solve for z first. The whole circle is 360° so if you only count half the angles it will add up to 180°.
Solve for z:
48+36+z=180°
84+z+180°
z=96°
Now that you have z you can solve for x by using only the bottom half of the circle.
z+36+6x=180° *remember z=96
96+36+6x=180
132+6x=180
6x=48
x=8°
Now you can solve for y by either plugging x into an equation or by knowing that opposite angles are equal.
y=96°
If f(x) = 5x - 3, fill out the following table of values:
-2,-1,0,1,2,3
What type of function is this?
Answer:
Step-by-step explanation:
Given function is,
f(x) = 5x - 3
Where f(x) represents the output values and 'x' is the variable representing the input values.
For x = -2,
f(-2) = 5(-2) - 3
= -13
For x = -1,
f(-1) = 5(-1) - 3
= -8
For x = 0,
f(0) = 5(0) - 3
= -3
For x = 1,
f(1) = 5(1) - 3
= 2
For x = 2,
f(2) = 5(2) - 3
= 7
For x = 3,
f(3) = 5(3) - 3
= 12
Table for the input-output values will be,
x -2 -1 0 1 2 3
f(x) -13 -8 -3 2 7 12
Since the values of f(x) has a common difference of [-13 - (-8) = -5] negative five, given function will be a linear function.
On a famous episode of Star Trek, Captain Kirk and the gang played a card game called Phisbin. This problem is about another game, called Frisbin. The object of Frisbin is to throw three Frisbees at three different-sized bins that are set up on the ground about 20 feet away from the player. If a Frisbee lands in the largest bin, the player scores 1 point. If a Frisbee lands in the medium-sized bin, the player scores 5 points. If a Frisbee lands in the smallest bin, the player scores 10 points. Kirk McCoy is playing the game. If all three of his Frisbees land in bins, how many different total scores can he make?
Answer:
10 different possible scores
Step-by-step explanation:
the total possible scoring combinations are:
large bin (1) medium bin (5) small bin (10) score
3 0 0 3
2 1 0 7
2 0 1 12
1 2 0 11
1 0 2 21
1 1 1 16
0 3 0 15
0 2 1 20
0 1 2 25
0 0 3 30
Using the principle of combination, the number of different total scores that can be made is 10.
Using the combination relation which includes repetition :
[tex] \binom{n + k - 1}{k} [/tex]n = number of Frisbee = 3 k = number of bins = 3Substituting the values into the formula :
[tex] \binom{3 + 3 - 1}{3} = \binom{5}{3} [/tex]
Using the combination formula :
[tex]nCk = \frac{n!}{(n-k)!k!}[/tex]
[tex]5C3 = \frac{5!}{(5-3)!3!}[/tex]
[tex]5C3 = \frac{5!}{2!3!}[/tex]
[tex]5C3 = \frac{5 \times 4}{2} = \frac{20}{2} = 10[/tex]
The number of different total scores that he can make is 10.

Bernie helped design a magician costume for a school play. He used 5.75 feet of ribbon for the magician's wand. He used 11.75 feet of the same ribbon to decorate the magician's robe. If Bernie used $10.50 of ribbon in all, how much did the ribbon cost per foot?
Answer:
The ribbon cost per foot $0.6 per foot
Step-by-step explanation:
Total number of ribbon used = (5.75 + 11.75) = 17.50 feet
17.50 feet of ribbon cost = $10.50
1 foot of ribbon cost = x
Cross Multiply
17.50 × x = 1 foot × $10.50
x = 1 foot × 10.50/17.50
x = $0.6
The ribbon cost per foot $0.6 per foot
Answer: $0.75
Step-by-step explanation:
Total amount used for the ribbons = $1.50
Total feet of ribbons used = 5.75 feet + 11.75 feet = 17.5 feet
The cost of ribbon per foot will now be:
= $10.50/17.5
= $0.6 per foot
A bakery sells 5 bagels for 7.50.There is a proportion relationship between the cost and the number of bagels,Which equation represents the cost in dollars, c, for b bagels?
Answer:
$1.5b
Step-by-step explanation:
If a bakery sells 5 bagels for $7.50, we are to find the equation that will represent the cost of b bagels. This can be gotten using the equality postulate as shown;
5 bagels = $7.50
b bagel = $c
Cross multiply
5*c = 7.50b
Divide both sides by 5
5c/5 = 7.50b/5
c = 1.5b
Hence the cost of b bagel c is $1.5b

Which lines are perpendicular to the line y - 1= 1(x+2)? Check all that apply
y2= -36% -4)
y-5=9(x - 11)
• y=-3x-2/
y = 1x-2
3x + y=7
) Intro
Done
Step-by-step explanation:
Given the line y-1 = 1(x+2), in order to know the line that is perpendicular to the given line, we will first find the slope of the known line.
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the intercept
Rewrite the equation given
y-1 = 1(x+2)
y-1 = x+2
y = x+2+1
y = x+3
Comparing to the standard form, the slope m = 1.
For two lines to be perpendicular, the product of their slope must be -1 i.e mM = -1
Substitute
1(M) = -1
M = -1
For us to know the line that is perpendicular to the given line, its slope must be -1.
Since none of the equation has a slope of -1, hence none of the lines are perpendicular to the line y - 1= 1(x+2).

In the figure, the measure of angle 9 is 80 degrees and the measure of angle 5 is 68. Find the measure of each angle.
Answer/Step-by-step explanation:
Given:
m<9 = 80°,
m<5 = 68°
Lines w and v are parallel to each other.
m<1 = m<9 (corresponding angles theorem)
m<1 = 80°
m<2 + m<1 = 180° (linear pair)
m<2 + 80° = 180° (substitution)
m<2 = 180° - 80°
m<2 = 100°
m<3 = m<1 (vertical angles are congruent)
m<3 = 80°
m<4 = m<2 (vertical angles are congruent)
m<4 = 100°
m<6 + m<5 = 180° (linear pair)
m<6 + 68° = 180° (substitution)
m<6 = 180° - 68°
m<6 = 112°
m<7 = m<5 (vertical angles)
m<7 = 68°
m<8 = m<6 (vertical angles)
m<8 = 112°
m<10 = m<2 (corresponding angles)
m<10 = 100°
m<11 = m<9 (vertical angles)
m<7 = 80°
m<12 = m<10 (vertical angles)
m<12 = 100°
m<13 = m<5 (corresponding angles)
m<13 = 68°
m<14 = m<6 (corresponding angles)
m<14 = 112°
m<15 = m<13 (vertical angles)
m<15 = 68°
m<16 = m<14 (vertical angles)
m<16 = 112°

Step-by-step explanation:
X-intercept(s) can be found when y = 0
Rearrange the equation
-3y = -2x + 11
y = 2x/3 - 11/3
Let y = 0
0 = 2x/3 - 11/3
Rearrange so that x is on one side
2x/3 = 11/3
x = 11/2

The quadratic function y = –10x2 + 160x – 430 models a store’s daily profit (y) for selling a T-shirt priced at x dollars. What equation do you need to solve to find the selling price or prices that would generate $50 in daily profit? What method would you use to solve the equation? Justify your choice.
Answer:
x = 4 or x = 12
Step-by-step explanation:
Given:
y = -10x² + 160x - 430
When y = $50
50 = -10x² + 160x - 430
50 + 430 = -10x² + 160x
480 = -10x² + 160x
-10x² + 160x - 480 = 0
Divide through by -10
x² - 16x + 48 = 0
Solve the quadratic equation using factorization method
+48 = -12 × -4
-16 = -12 -4
Therefore,
-12 and -4 are both factors
x² - 16x + 48 = 0
(x - 4 )(x - 12 ) = 0
x - 4 = 0
x = 4
OR
x - 12 = 0
x = 12
Answer:
Replace y in the equation with 50: (50 = -10x2 +160x - 430) Use factoring to solve the equation. After writing the equation in standard form and dividing each side by -10, it is easy to factor as 0 = (x - 4)(x - 12).
Step-by-step explanation:
4x + 11y = 36, What is the x intercept (let y = 0)? *
To find the x intercept we must put zero instead of the y in the function.
Let's do it....
[tex]4x + 11(0) = 36[/tex]
[tex]4x + 0 = 36[/tex]
[tex]4x = 36[/tex]
Divided sides by 4
[tex] \frac{4}{4}x = \frac{36}{4} \\ [/tex]
[tex]x = 9[/tex]
Thus the x intercept is 9 .
And we're done....

Given:
A new four way intersection is being constructed in New York Hyde park through point P(-3,-15).
Equation of line of one road : [tex]y=-\dfrac{3}{4}x+7[/tex].
New road that will run perpendicular to the first road
To find:
The equation of line for the new road.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
We have,
[tex]y=-\dfrac{3}{4}x+7[/tex]
Slope of this line is [tex]-\dfrac{3}{4}[/tex] and y-intercept is 7.
Product of slopes of two perpendicular line is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{3}{4}\times m_2=-1[/tex]
[tex]m_2=\dfrac{4}{3}[/tex]
The point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
The slope of new line is [tex]\dfrac{4}{3}[/tex] and it passes through P(-3,-15). So, the equation of line of new road is
[tex]y-(-15)=\dfrac{4}{3}(x-(-3))[/tex]
[tex]y+15=\dfrac{4}{3}(x+3)[/tex]
[tex]y+15=\dfrac{4}{3}x+4[/tex]
Subtract 15 from both sides.
[tex]y=\dfrac{4}{3}x+4-15[/tex]
[tex]y=\dfrac{4}{3}x-11[/tex]
Therefore, the equation of the line representing the new road is [tex]y=\dfrac{4}{3}x-11[/tex].
