Find the missing angle x
Answer:
144° or 36°- depends on what you are asking.
Step-by-step explanation:
Since there are 190° in a straight line and there is 36° on one side. I then substracted 190-36 to get 144°.
If you are asking for the missing side of the triangle then the answer is 36° since this triangle is an equilateral triangle.

x is directly proportional to the square of y.
.
y is directly proportional to the cube of z.
z= 2 when x = 32
Find a formula for r in terms of z.
The direct variation of x to y implies that x and y increases at the same time, and the formula of x in terms of z is [tex]x = 4z^3[/tex]
How to determine the formula for x?The direct proportion of x to y is represented as:
[tex]x\ \alpha\ y^2[/tex]
As an equation, we have:
[tex]x\ =\ ky^2[/tex]
The direct proportion of y to z is represented as:
[tex]y\ \alpha\ z^3[/tex]
As an equation, we have:
[tex]y\ =\ kz^3[/tex]
Square both sides
[tex]y^2 = k^2z^3[/tex]
Substitute [tex]y^2 = k^2z^3[/tex] in [tex]x\ =\ ky^2[/tex]
[tex]x =k^3z^3[/tex]
When z = 2, x = 32.
So, we have:
[tex]32 =k^3 * 2^3[/tex]
Evaluate
[tex]32 =k^3 * 8[/tex]
Divide both sides by 8
[tex]k^3 =4[/tex]
Substitute [tex]k^3 =4[/tex] in [tex]x =k^3z^3[/tex]
[tex]x = 4z^3[/tex]
Hence, the formula of x in terms of z is [tex]x = 4z^3[/tex]

Miguel cabrera has had 369 at bats, and he has 127 hits and 21 home runs. (note: the home runs are included in the hits data.) if he is challenged to a batting battle, what is the expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run?
The expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run is 0.57
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Number of bats = 369
Number of hits = 127
Number of home runs = 21
The probability of a hit:
[tex]=\frac{127}{369}[/tex] (includes home run)
The probability of home run:
[tex]=\frac{21}{369}[/tex]
The probability of hit run(without home run)
[tex]=\frac{127}{369}-\frac{21}{369}[/tex]
[tex]=\frac{106}{369}[/tex]
The probability of no hit:
[tex]=\frac{369-127}{369}[/tex]
[tex]=\frac{242}{369}[/tex]
For home run, the score will be 5 points.
If not, a home run score will be 1 points.
If Miguel does not get hit, score will be zero point.
Expected value of Miguel hit at each bat is (without home run):
For 5 hit:
[tex]=\frac{106}{369}[/tex]
For 21 home runs, the points will be 21×5 = 105 (5 points for each home run)
The expected value for this:
[tex]\frac{105}{369}[/tex]
Adding both expected hits, we get:
[tex]=\frac{106}{369}+\frac{105}{369}[/tex]
[tex]=\frac{211}{369}[/tex]
= 0.571 ≈ 0.57
Thus, the expected score of each at bat if he earns 1 point for each hit that is not a home run and 5 points for each home run is 0.57

Answer:
[tex]\mathrm{Slope = \dfrac{1}{2}}[/tex]
Step-by-step explanation:
To find the slope of a graph, we use the formula below:
[tex]\mathrm{m =\dfrac{y\x_{2}-y\x_{1}}{x\y_{2}-x\y_{1}}}[/tex]
m = slope
(x1, y1) = coordinates of first point in the line
(x2, y2) = coordinates of second point in the line
Step 1: Find any two points on the line
Lets choose: (0, 3) and (2, 4)
Step 2: Put these points into the slope formula
[tex]\mathrm{m =\dfrac{y\x_{2}-y\x_{1}}{x\y_{2}-x\y_{1}}}[/tex]
Step 3: Substitute points into formula
[tex]\mathrm{m =\dfrac{4-3}{2-0}}[/tex]
Step 4: Subtract 3 from 4 and 0 from 2
[tex]\mathrm{m =\dfrac{1}{2}}[/tex]
----------------------------------------------------------------------------------------------------------
Another way you could easily do this is:
Step 1: Find two ponts on the line
For this problem, let's use (0, 3) and (2, 4)
Step 2: Then from the first point, how much do you need to go up and to the left or right to get to the second point
For this problem, we start on the on the point (0, 4) and go up by 1 and then to the right by 2
Step 3: Then you do rise over run to get the slope
The slope is rise over run:
Rise = 1
Run = 2
So, the slope is 1/2

What value of x is in the solution set of 9(2x 1) < 9x – 18? –4 –3 –2 –1
Inequalities help us to compare two unequal expressions. The value of x which is the solution set of 9(2x+1)<9x–18 is -4.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
To know which value will satisfy the inequality we need to substitute each of the values into the inequality,
A) x=-4
[tex]9(2x+1) < (9x-18)\\\\9[2(-4)+1] < [9(-4)-18]\\\\9(-8+1) < (-36-18)\\\\9(-7) < -54\\\\-63 < -54[/tex]
Since the inequality is satisfied this is the solution set of the inequality.
Thus, the value of x which is the solution set of 9(2x+1)<9x–18 is -4.

Answer:
$216
Step-by-step explanation:
First, find out what Mary makes every hour. To find this, we divide 144 by 8.
144/8 = $18
This means that Mary makes $18 per hour.
Now, we find out how much Mary would make if she worked for 12 hours:
x = # of hours worked
18n
18(12)
$216
Therefore, Mary would make $216 in 12 hours.

Triangle EFG has an area of 70 m².
EF: FG= 1:2 and angle EFG = 40°.
(a) Calculate EF.
The measure of length EF is the triangle EFG has an area of 70 m² is 7.38m
How to calculate the area of a triangle?A triangle is a 2-dimensional shape with 3 sides and angles. The formula for calculating the area of a triangle is expressed as:
A = (EF)(FG) sin theta
If the ratio of EF to FG is 1:2, then FG = 2EF
A = (EF)(2EF) sin theta
70 = 2EF²sin40
70 = 1.2856EF²
EF² = 54.474
EF = 7.38m
