OA) 30°
O B) 60°
D) 50°
OC) 90°
Answer:
A) 30°
Step-by-step explanation:
Sum of three angles of a triangle = 180°
75° +75° + ∠WYZ = 180°
Add like terms
150° + ∠WYZ = 180°
Subtract 150°from both sides
∠WYZ = 180 - 150
∠WYZ = 30°

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Two line segments are parallel if and only if their slopes are equal.
If the slopes of two lines are equal, then they have the same steepness and will never intersect.
However, if the slopes are different, the lines will intersect at some point, and they will not be parallel.
Thus,
Two line segments are parallel if and only if their slopes are equal.

Nikki works at a store that sells consumer electronics. She earns $12 per hour, plus a commission of 5% of her total sales amount each day. Nikki worked 8 hours on Saturday. Including her commission, Nikki earned a total of $139 on Saturday. Which equation can be solved for x, Nikki’s total sales amount in dollars on Saturday?
Answer:
See below.
Step-by-step explanation:
So, Nikki earns $12 per hour.
And she also earns a 5% or 0.05 commission of her total sales each day.
On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.
Thus:
[tex]139=96+0.05x[/tex]
Where x represents Nikki's total sales on Saturday.
Further notes:
To solve, subtract 96 from both sides and divide by 0.05:
[tex]139=96+0.05x\\43=0.05x\\x=\$860[/tex]
Thus, her total sales that day were $860.

Joshua spins a spinner twice. The spinner consists of 3 equally spaced colors, Red, Blue, and Yellow. What is the probability that the spinner will stop on green and then yellow? ASAP
Answer:
[tex]\dfrac{1}{9}[/tex]
Step-by-step explanation:
Given a spinner with 3 equally spaced colors Red, Blue, Yellow.
The colors are equally spaced, therefore probability of each color must be same.
i.e. Probability of occurrence of any one color in one spin is [tex]\frac{1}{3}[/tex].
To find:
Probability that spinner will stop one green in first spin and yellow in the second spin = ?
Solution:
As all the colors are equally likely to occur, so
Probability of green color in the first spin, P(G) = [tex]\frac{1}{3}[/tex]
Probability of yellow color in the second spin, P(Y) = [tex]\frac{1}{3}[/tex]
As we can observe that occurrence of any color in the second round of spin is not dependent on the color occurrence in the first spin, therefore these are the independent events.
P(G and Y) = P(G) [tex]\times[/tex] P(Y)
[tex]\Rightarrow P(G\ and\ Y) = \dfrac{1}{3} \times \dfrac{1}{3}\\\Rightarrow P(G\ and\ Y) = \bold{\dfrac{1}{9}}[/tex]
Therefore, the required probability is
[tex]\dfrac{1}{9}[/tex].

Step-by-step explanation:
Given that :
Coordinate of point A = - 7, - 3
Number of points between point A and B = 12
Possible coordinate of point B
Possible coordinates of point B:
(-7, - 3) + 12 = (5, 9)
(-7, - 3) - 12 = (-19, - 15)
(-7, - 3) = (-7 +12, -3 - 12) = (5, - 15)
(-7, - 3) = (-7 - 12, - 3 + 12) = (-19, 9)
Hence possible coordinates of be are :

Eighty percent of adults drink coffee and seventy percent drink tea. What is the smallest possible percent of adults who drink both coffee and tea?
Answer:
50%
Step-by-step explanation:
Given that Eighty percent ( 80%) of adults drink coffee and seventy ( 70%) percent drink tea.
Let the percent of the adults that drink coffee and tea be y
The total percentage of adults = 100
80 - y + y + 70 - y = 100
150 - y = 100
- y = 100 - 150
Y = 50.
Therefore, the smallest possible percent of adults who drink both coffee and tea is 50 %
A Simpler Answer:
Add together the probabilities.
80%+70%=150%
Therefore we overcounted 50 percent, so the least amount possible is [tex]\boxed{50\%}[/tex]

-4.75 = x/2 what is x
Answer:
x= -9.5
Step-by-step explanation:
We want to find out what the variable, x, is equal to. Therefore, we must isolate the variable on one side of the equation.
-4.75 = x/2
x is being divided by 2. The inverse of division is multiplication. Multiply both sides of the equation by 2.
2*(-4.75) = (x/2)*2
2*(-4.75)=x
2* -4.75=x
Multiply 2 and -4.75
-9.5=x
Let's check our solution. Plug -9.5 back in for x and solve.
-4.75= x/2
-4.75= -9.5/2
-4.75= -4.75
This checks out, so we know our solution is correct.
x is equal to -9.5
Answer:
[tex]x = \frac{19}{2} [/tex]
Step-by-step explanation:
[tex] \frac{x}{2} = - 4.75[/tex]
First convert the decimal to an improper fraction
That's
[tex] - 4.75 = - \frac{19}{4} [/tex]
So we have
[tex] \frac{x}{2} = - \frac{19}{4} [/tex]
Cross multiply
4x = - 38
Divide both sides by 4
We have the final answer as
[tex]x = \frac{19}{2} [/tex]

Yearly Salary: $20.000. Bonus for each game that attracts 100+ fans: $8.000.
Answer:
on average, the pitcher expects to earn 18.3 bonuses per year
Step-by-step explanation:
Total amount earned over the next 6 years = $1,000,000
salary per year = $20,000
salary for the next 6 years = 20,000 × 6 = $120,000
Next, let us calculate the amount earned from bonuses:
Total amount earned = amount earned from salaries + amount earned from bonuses
$1,000,000 = 120,000 + Amount earned from bonuses
Amount earned from bonuses = 1,000,000 - 120,000
Amount earned from bonuses = $880,000
Total bonus amount earned over six years = $880,000
Amount of bonus earned per game = $8,000
Number of bonuses received over the next 6 years = (Total bonus earned over six years) ÷ (Amount of bonus earned per game)
Number of bonus received over the next 6 years = 880,000 ÷ 8,000
Number of bonus received over the next 6 years = 110 bonuses
6 years = 110 bonuses
1 year = 110 ÷ 6 = 18.33 bonuses
on average, the pitcher expects to earn 18.3 bonuses per year
