How do I find the value of x?
Answer:
Since you're asking how to find the value of x, you can use cosine, since the triangle is a right triangle.
Answer:
Only cosine include both hypotenuse and adjacent. We need both of them because those are 2 side that have numbers/letters.
So cos(28) = 11/x
Multiply by x
Then you'll get xcos(28) = 11
Do oposite cosine and you'll get
x = 11*opposite cos(28)
opposite cosine means cos^-1
thats approx. equal to 12.46 units

Answer:
9. 40°
10. 50°
11. 270°
12. 310°
Step-by-step explanation:
m∠BPC = 40° because it is complementary to ∠APB, which is 50°.
Arc AB is 50° because it will be equal to the central angle, which is 50°.
Arc ADC is 270° because it will be equal to the central angle, which is 270°.
Arc ADB is 310° because it will be equal to the central angle, also 310°.

AB is a segment with one endpoint A(-7,9) and midpoint M(8,1). Can
you find the coordinates of the other endpoint B?
Enter the x-coordinate of the other endpoint here
Enter the x-coordinate of the other endpoint here
Answer:
x-coordinate of the other endpoint: 23
y-coordinate of the other endpoint: -7
Step-by-step explanation:
To find the x-coordinate of the other endpoint, we need to find the run between the known endpoint and the midpoint
run: xM - xA = 8 - (-7) = 15
where xM and xA are the x-coordinates of M and A respectively.
The run between the other endpoint and the midpoint must be the same as before:
x - 8 = 15
x = 15 + 8
x = 23
To find the y-coordinate of the other endpoint, we need to find the rise between the known endpoint and the midpoint
rise: yM - yA1 = - 9 = -8
where yM and yA are the y-coordinates of M and A respectively.
The rise between the other endpoint and the midpoint must be the same as before:
y - 1 = -8
y = -8 +1
y = -7

Find the equation of the line. Use exact numbers. y=y=y, equals x+x+x, plus 5
Answer:
y=3x+5
Step-by-step explanation:
y=y=y=x+x+x+5 is what I think you were saying. In that case:
y=x+x+x+5
y=3x+5
The equation of the line is y=3x+5
The equation of the given line is y = 2/3 x - 2
The standard form of the equation of a line is expressed as y = mx + b
m is the slope of the line
b is the y-intercept
from the diagram attached, we can use the coordinate (0, -2) and (3, 0)
Get the slope
Slope "m" = 0-(-2)/3-0
m = 2/3
Since the line cuts the y-axis at y = -2, hence the y-intercept is b = -2
Substitute the given parameters into the equation:
y = mx + b
y = 2/3 x + (-2)
y = 2/3 x - 2
Hence the equation of the given line is y = 2/3 x - 2

Solve |4x +2|= 6
a.1 or -2
b.-1 or 2
c.1
s.2
Answer:
A
Step-by-step explanation:
When taking out the absolute value, it's 4x+2=6 and 4x+2=-6. At this point just solve for x and your answer(s) should be 1/-2
Answer:
x =1 x=-2
Step-by-step explanation:
|4x +2|= 6
There are two solutions a positive and a negative
4x+2 = 6 and 4x+2 = -6
Subtract 2 from each side
4x+2-2 = 6-2 4x+2-2 = -6-2
4x = 4 4x = -8
Divide by 4
4x/4 = 4/4 4x/4 =-8/4

Use the discriminant to determine the number of real solutions to the quadratic equation. −u2+2u−5=0 What is the number of real solutions? Select the correct answer below: 0 1 2
Answer: None, 0 real roots
Step-by-step explanation:
To find the discriminant, you simply do [tex]b^2 - 4ac[/tex]
b = 2
a = -1
c = -5
[tex]2^2-4(-1)(-5) = 4 - 20 = -16[/tex]
iff x > 0: 2 roots
iff x < 0: none
iff x = 0: 1 root
Actual Explanation and Intuition behind it:
If the answer is negative, you cant take the square root of the number. Because no matter what, you will always strive for a positive number. Unless you implement calculus, but that is way beyond a middle schoolers level
If the answer is postive, there will be 2 roots because you can make x itself equal to a negative number because when you square it, it will be positive. So the positive and negative value will be an acceptable answer
If the answer is 0, then youre basically doing the square root of 0. Thats equal to 0
The discriminant formula itself comes straight from the quadratic formula, which you should memorize because it is extremely useful.[tex]\frac{-b (+/-) \sqrt{b^2-4ac} }{2a}[/tex]
How many solutions does the following system of equations have? y=5/2x+2 and 2y=5x+8
Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.

Kim’s family spends $62.50 on dinner. They leave an 18% tip. How much is their total bill after tip?
Answer:
51.25
Step-by-step explanation:
Multiply 62.5 by .18. You get 11.25. Subtract that from 62.5 and you get 51.25.
Answer:
Multiply the price with the tip rate
18% = 0.18
62.5 x 0.18 = 11.25
that is the tip. We add that on to find the total price
62.5 + 11.25 = 73.75
73.75 dollars is the answer. Hope this helps

remove the top 24" of contaminated soil in order to make
sure the soil is not a health hazard. The soil covers a
1200' x 1500'lot. How much soil must be removed?
Answer:
Area to be removed = 3600000 feet³
Step-by-step explanation:
We need to calculate the volume of soil to be removed. We have been already provided with area of the lot in feet.
Total Area of soil = 1200' x 1500'
Where soil to be removed is given in inches, convert it into feet
Soil to be removed = 24''=2'
Multiply both the the value to get the volume of soil to be removed so the soil is not a health hazard
Area to be removed = 1200' x 1500' x 2'
Area to be removed = 3600000 feet³

II'll mark brainliest who is the first to answer both questions correctly.
A)
You take the four Aces, four 2's, and four 3's from a standard deck of 52 cards, forming a set of 12 cards. You then deal all 12 cards at random to four players, so that each player gets three cards. What is the probability that each player gets an Ace, a 2, and a 3?
B)
In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from 1 to 10, and one SuperBall is drawn (at random) from ten red balls numbered from 11 to 20. When you buy a ticket, you choose three numbers from 1 to 10, and one number from 11 to 20.
Answer:
A) The probability that each player gets an ace, a 2 and a 3 with the order unimportant = (72/1925) = 0.0374
B) The probability of winning the jackpot = (1/1200) = 0.0008333
Step-by-step explanation:
A) There are four Aces, four 2's, and four 3's, forming a set of 12 cards
These cards are to be divided at random between 4 players.
What is the probability that each player gets an ace, a 2 and a 3.
We start with the first player, the probability of these cards for the first player, with order not important (because order isn't important, there are 6 different arrangement of the 3 cards)
6 × (4/12) × (4/11) × (4/10) = (16/55)
Then the second player getting that same order of cards
6 × (3/9) × (3/8) × (3/7) = (9/28)
Third player
6 × (2/6) × (2/5) × (2/4) = (2/5)
Fourth player
6 × (1/3) × (1/2) × (1/1) = 1
Probability that each of the players get different cards is then a multiple of the probabilities obtained above
= (16/55) × (9/28) × (2/5) × 1
= (288/7700) = (72/1925) = 0.0374
B) The concluding part of the B question.
To win the jackpot, the numbers on your ticket must match the three white balls and the SuperBall. (You don't need to match the white balls in order). If you buy a ticket, what is your probability of winning the jackpot?
Probability of wimning the jackpot is a product the probability of getting the 3 white balls correctly (order unimportant) and the probability of picking the right red superball
Probability of picking 3 white balls from 10
First slot, any of the 3 lucky numbers can fill this slot, (3/10)
Second slot, only 2 remaining lucky numbers can fill this slot, (2/9)
Third slot, only 1 remaining lucky number can fill this slot, (1/8)
(3/10) × (2/9) × (1/8) = (1/120)
Probability of picking the right red superball
(1/10)
Probability of winning the jackpot = (1/120) × (1/10) = (1/120) × (1/10) = (1/1200) = 0.0008333
Hope this Helps!!!
