Answer•Pic on the left
x = 8.36
y = 140.18°
• Pic on the right
x = 110°
Way to do• This one for the pic on the left
#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)
#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D
90 = (5x - 2) + 6x
90 = 11x - 2
90 + 2 = 11x
92 = 11x
x = 92 : 11
x = 8.36 (2 decimal places)
#Now you know the x, you can now find the degree
#degree of (5x - 2)
5x - 2 =
5(8.36) - 2 =
41.81 - 2 = 39.81
#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)
180° - 39.81° = 140.18
•This one for the pic on the right
#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.
# Also as i said before, total triangle degree is 360°
#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)
Degree = 180° - 80° - 30° = 70°
#Now you can get x
x = 180° - 70° = 110°

10 Six years ago Jon was one-sixth the age of his mother
and in four years time his age doubled and increased
by 10 will match his mother's age. How old is Jon
now?
Answer:
Jon is 11 years old
Step-by-step explanation:
We write the following equations describing the sentences of the problem, using the letter M to represent Jon's mom's current age, and j to represent his current age.
First sentence: "Six years ago Jon was one-sixth the age of his mother."
translates into:
J - 6 = (M - 6) / 6
Second sentence: "in four years time his age doubled and increased
by 10 will match his mother's age."
2 * (J + 4) + 10 = M + 4 which removing parentheses gives: 2 J + 18 = M + 4
We solve for "M" in the first equation
6 (J - 6) = M - 6
6 J - 36 = M - 6
M = 6 J - 30
and now use this result to substitute for M in the second equation
2 J + 18 = (6 J - 30) + 4
and work on solving for J
2 J + 18 = 6 J - 30 + 4
18 + 26 = 6 J - 2 J
44 = 4 J
J = 44 / 4
J = 11
How many times does X squared minus 4X -12 cross the X axis
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D

Step-by-step explanation:
Gold’s gym charges $30 membership fee plus $3 for each workout, while Titletown charges $40 membership fee plus $1 for each workout.
Let x = number of workouts
Let y = total costs
Gold's Gym: y = 30 + 3x
Titletown Fitness: y = 40 + x
How many workouts does a person have to do until the total costs are equal?
Answer:
5 workouts should be performed to equalize the costs between both gyms.
Step-by-step explanation:
Given that Gold’s gym charges $ 30 membership fee plus $ 3 for each workout, while Titletown charges $ 40 membership fee plus $ 1 for each workout, to determine how many workouts does a person have to do until the total costs are equal, the following calculation must be performed:
Gold's Gym: y = 30 + 3x
Titletown Fitness: y = 40 + x
Gold's Gym: y = 30 + 3x2 = 36
Titletown Fitness: y = 40 + 2 = 42
Gold's Gym: y = 30 + 3x3 = 39
Titletown Fitness: y = 40 + 3 = 43
Gold's Gym: y = 30 + 3x4 = 42
Titletown Fitness: y = 40 + 4 = 44
Gold's Gym: y = 30 + 3x5 = 45
Titletown Fitness: y = 40 + 5 = 45
Thus, 5 workouts should be performed to equalize the costs between both gyms.

Answer:
14.13
Step-by-step explanation:
Formula for area of a semicircle: 3.14*r*r/2
6/2 = 3
3*3=9
3.14*9 = 28.26
28.26/2 = 14.13

Assume a test for a disease has a probability 0.05 of incorrectly identifying an individual as infected (False Positive), and a probability 0.01 of incorrectly identifying an individual as uninfected (False Negative). Assume furthermore that the probability of an individual being infected is 0.000001 (1 in 1 million). If a person tests positive for this disease, what is the probability of actually having the disease
Answer:
0.00002 = 0.002% probability of actually having the disease
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive test
Event B: Having the disease
Probability of having a positive test:
0.05 of 1 - 0.000001(false positive)
0.99 of 0.000001 positive. So
[tex]P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094[/tex]
Probability of a positive test and having the disease:
0.99 of 0.000001. So
[tex]P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}[/tex]
What is the probability of actually having the disease
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{9.9 \times 10^{-7}}{0.05000094} = 0.00002[/tex]
0.00002 = 0.002% probability of actually having the disease
Aspen has 10 pairs of white socks and 1 pair of red socks. What is the chance that Aspen wears a pair of black socks?
Answer:
no chance
Step-by-step explanation:
he doesn't have any black socks
Answer:
Step-by-step explanation:
Of the ten socks,
10/11 chance of wearing white socks
1/11 chance of wearing red socks
0/11 chance of wearing any OTHER color
Black socks fall into the final row, which is the OTHER color, meaning there is no chance he can wear black socks.

When plotting points on the coordinate plane below, which point would lie on the x-axis?
(6, 0)
(0, 2)
(3, 8)
(5, 5)
Answer: (6,0)
Coordinate points are always written in pairs of the x- and y-coordinate: (x, y). Knowing this, the point would need to have a y-value of 0 in order to lie on the x-axis (otherwise, it would be on a random spot on the grid). The only coordinate point with a y-value of 0 is (6, 0). Therefore, the coordinate point (6, 0) lies on the x-axis.
Please refer to the attached graph below to see all the coordinate points.
Please help please please
Answer:
C. y = 2x + 8
Step-by-step explanation:
✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):
Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))
Slope (m) = 16/8
m = 2
✔️Find the y-intercept (b):
To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b
Thus:
20 = 2(6) + b
20 = 12 + b
20 - 12 = b
8 = b
b = 8
✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b
Thus:
y = 2x + 8

Ben Frank is an electrician who installs lighting fixtures. He charges (in dollars) his clients 15h +40f
where h is the number of hours worked and f is the number of fixtures installed.
How much does Ben Frank charge when he works 7 hours and installs 9 fixtures?
Answer:
465 Dollars
Step-by-step explanation:
15h+40f = Amount Charged
if: h = 7
f = 9
15(7)+40(9) = Amount Charged
105 + 360 = Amount Charged
465 = Amount Charged
He will charge 465 dollars.
15h + 40f
Step 2:= 15(7) + 40(9)
Step 3:= 105 + 360
Step 4:= $465

9514 1404 393
Answer:
f(x), h(x), g(x)
Step-by-step explanation:
For a quadratic in standard form, ...
ax² +bx +c
the axis of symmetry is ...
x = -b/(2a)
For the various functions, the axes of symmetry are ...
f(x): x = 0/(2·3) = 0
g(x): x = -(-4)/(2·1) = 2
h(x): x = (-4)/(2(-2)) = 1
From least to greatest axis of symmetry the functions are ...
f(x), h(x), g(x)
