Answer:
$45,000
Step-by-step explanation:
Income = percentage of income she receives x income
50% x 90,000

What is the probability that the arrow will land on 1 or 2?
A. 2/5
B. 2/3
C. 3/4
D. 1/5
The probability that the arrow will land on 1 or 2 is 2/5.
What is Probability ?Probability is the ratio of occurring a certain event out of the total possible events.
If the given statement contains OR we use addition and if the given statement contains AND we use multiplication.
From the given data
Total no. of regions in the circle is 5
The probability that the arrow will land on 1 or 2 is
P(1) = 1/5
P(2) = 1/5
∴ P(1) or P(2) is
= 1/5 + 1/5
= 2/5
Here we have used addition because of OR statement.

Statement 1 and statement 3 contradict
======================================================
Explanation:
We'll start with statement 1 and try to build to statement 3, and you'll find that a contradiction happens.
If angle 1 and angle 2 are supplementary, then that must mean [tex]m \angle 1 + m \angle 2 = 180[/tex] because the angles can be combined to form a straight angle.
Add the measure of angle 3 to both sides
[tex]m \angle 1 + m \angle 2 = 180\\\\m \angle 1 + m \angle 2+m\angle 3 = 180+m\angle 3[/tex]
The left side matches with the left side in statement 3, but the right side is a bit off. That [tex]m\angle 3[/tex] term needs to be zero, so that the right side boils down to simply 180. However, statement 3 specifically mentions that angle 3 is nonzero. So angle 3 is some positive value.
That's why choice C is the answer.
------------------
Here's an example:
Let's say angles 1 and 2 are 50 and 130 degrees. The order doesn't really matter, but I'll make angle 1 to be the smaller angle.
This means,
[tex]m \angle 1 + m \angle 2 = 180\\\\50 + 130 = 180\\\\[/tex]
So we've made statement 1 to be true. The angles 50 and 130 are indeed supplementary.
Now let's add some nonzero value to both sides. This will represent the measure of angle 3. If we add say 10 degrees to both sides, then,
[tex]50 + 130 = 180\\\\50 + 130+10 = 180+10\\\\50 + 130+10 = 190\\\\m\angle 1 + m\angle 2 + m\angle 3 = 190\\\\[/tex]
we don't get 180 like we want in the equation of statement 3. This is where the contradiction happens, more or less. One right side is 180, the other right side is 190. The 190 will change if you use some other value for angle 3, but hopefully you can see that it's impossible to add up angles 1 through 3 to get 180. It's only possible if angle 3 were zero degrees.
We can think of it like angles 1 and 2 hog up all the oxygen, and use up 180 points of it, leaving no air for angle 3 to breathe so that's why angle 3 must be 0. Furthermore, it means that a triangle is not possible if exactly two angles are supplementary.
----------------------
Extra info:
Statements 1 and 2 can coexist just fine without any contradictions happening. If angle 1 is 110 degrees, then that makes angle 2 to be 70 degrees (110+70 = 180). That rules out choice A.Statements 2 and 3 are just fine as well, for similar reasoning as above. We can plug in 110 for angle 1, then subtract that from 180 to get 180-110 = 70. Then from here, just ensure that angles 2 and 3 add to 70. So there are infinitely many ways to do this. Choice B can be ruled out.Choice D is ruled out because we found choice C to be the answer, ie the contradicting two statements.Answer:
C) l and lll
Step-by-step explanation:
m∠1+∠2=180
m∠1+m∠2+m∠3=180
180+m∠3=180
m∠3=0 but m∠3=∦0

Answer:
d. more than 95%
Step-by-step explanation:
According to a survey carried out by the Food Drug Administration from 2016 to 2017, termed Population Assessment of Tobacco and Health, it was discovered that a high percentage of the youth population smoked e-cigarettes with special flavorings. Specifically, it was found that 96.1% of young people within the ages of 12 to 17 started their use of e-cigarettes with the flavored options.
As at the time when the report was being published, 97% of e-cigarette users reported having used flavored e-cigarettes in the past month. The above data shows that more than 95% of youths that vape have smoked e-cigarettes with special flavorings.
Find the values of x and y. Write your answers in simplest form.
Answer:
To find X you'll need this formula Tan 30, and this one to find y cos 30.
Step-by-step explanation:
tan 30 = 9 / x.
tan 30*x = 9
x = 9 / tan 30
x = 15.58
To find y, the value of X will be needed, which is 15.5 that we just found.
Cos= A/H
Cos 30 = 15.58/ y
Cos 30 * y = 15.58
y = 15.58/ cos 20
y = 17.99
A circular plate has circumference 33.3 inches. What is the area of this plate? Use 3.14 for Pi.
The area of this plate is_____about square inches.
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest
thousandth as needed.)
Answer:
88 square inches
Step-by-step explanation:
A circular plate has circumference 33.3 inches.
Step 1
We find the radius
The formula to find the radius go a circle given circumference is
= C /2π
r = 33.3/2 × 3.14
r = 5.3025477707 inches
Approximately to the nearest thousandth = 5.303 inches
Step 2
What is the area of this plate? Use 3.14 for Pi.
The area of a circle = πr²
Where
π = 3.14
r = 5.3025477707 inches
Hence
Area of the circle = 3.14 × (5.303inches)²
= 88.30248026 square inches
Approximately to the nearest whole number the area of the circle = 88 square inches
The area of this plate is about 88 square inches.

SHOW YOUR WORK. The volume of the cylinder is 235.6 ft cubed. Find the height.
Answer:
Answer: 3 feet
Step-by-step explanation:
Here's the complete question:
The volume of the cylinder is 235.6 cubic feet the radius is 5ft. Find the height.
Note that Volume of a cylinder = πr²h
where Volume = 235.6 feet³
Radius = 5 feet
Height = Unknown
Then, we put the values back into the question and this will be:
V = πr²h
235.6 = 3.14 × 5² × h
235.6 = 3.14 × 25 × h
235.6 = 78.5 × h
h = 235.6 / 78.5
h = 3 feet
The height is 3 feet

Find the tangent line equation of the curve at the given point. Y=arcsin(7x) at the point where x=sqrt2/14
Answer:
[tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]
Step-by-step explanation:
The equation of the curve is
[tex]Y = sin^{-1}(7x)[/tex]
To find the equation of tangent we need to differentiate this equation w.r.t x
So, differentiating we get
[tex]Y'=\frac{7}{\sqrt{1-49x^2} }[/tex]
This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is [tex]x = \sqrt{\frac{1}{7} }[/tex]
Then slope would accordingly be
[tex]Y'=\frac{7}{\sqrt{1-49/49} }[/tex]
= ∞
For, [tex]x = \sqrt{\frac{1}{7} }[/tex], [tex]Y = sin^{-1}(7/7)= \pi/2[/tex]
Equation of tangent line, in the point slope form, would be [tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

Answer:
78 cm^2
Step-by-step explanation:
This will require 3 steps.
1) Area of the entire rectangle
18cm * 8 cm = 144 cm^2
2) Area of the square with one side length of 9cm
The missing measurement for the heights below 2cm
8cm - 2 cm = 6 cm
This area will be 6cm * 9 cm = 54 cm^2
3) Triangle
You have your height, which is 6cm
You also have your base, 18 cm total length minus the 5 cm stated minus the 9 cm also stated.
18cm - 5cm - 9 cm = 4 cm
The area of a triangle is A= h b/2
A = 6 * (4/2)
A = 12 cm^2
Now substract the sum of the smaller rectangle and the triangle from your large triangle
