As you can see, I have my subsidies trying out and, like, a lot of time president focused on assessing. Okay, so we need to figure out what seat for the size that we're giving you could put them in any order you want. So we're gonna try this order for us, and then we're gonna try. So we're gonna do you know that the inside of the a softly triangle in this out of this triangle are equal to each other. And when you add them together, there has to be greeted with this out of this. Had a trying. So we're first gonna do three t is equal to five t oneness. Well, arguments of drugs five from both sides fascinate this negative to t is equal to negative. After this, we could divide negative to on both sides to find out what see is to get T bites so tracked, divided by negative tune. And then we're gonna do t is equal to negative 12 of our negative to 6 36 So we're going to check our solution by plugging in six. So when we plug six into this equation, we're gonna gate 18 3 times six is 18. And when we plug six into this equation, we're gonna get five times six, which is dirty five times six is 30 and you're going to subtract. Told him 30 that gave to. And then we're gonna put 6 40 and we're gonna add it to Tony, which is 26. And then after this, we're gonna add these two 18 18 to figure it out if it's hired into 6 18 plus 18 is 36. So it's harder 26 c is equal to is equal to six. Like I said before, this is not the only order because switch up the sides with them in different places. So I'm gonna take away this side. I took a week this, and I'm gonna put I want to take with this ad too, and I'm in. I'm gonna put t this 20 this side and five C minus. Whoa, This Okay, so we're gonna do the same thing we did over here. We're gonna do three t is equal to C plus 25 because these two sides great. See? Do you see before? See e waas 20 first. We're going to subtract C from both sides we're gonna get to t is equal to finding. And then we're gonna divide to from both sides to get by itself. And, uh, an anti is equal to 10 because 20 the bottom right to it. So we also know that he gave me 10. So we're gonna plug 10 in today, San plus 10 times their times three is equal to this is dirty. And we also know we're gonna put 10 for this side. A tent was 20 is dirty also, it's an end times what? It's 50 When you subtract well, you get 36. No, you get 30 feet, you get 38 when you add 30 plus dirty is 60. So this works. So t is also equal to 10 and we're gonna switch up the order again. This sound this one, I believe this one. And also as you know, we're switching at the side, trying all the possible leads with right. Let's go drop this trying. So this side now will be treaty. And this I will be five c minus slow. We're gonna go. We're gonna do five minutes. 12 is equal to 10 is equal city plus 20 because we know these two sides has equal five feet on its 12. I just love equal See loose. Okay, As you can see, we're going to subtract, see from both sides. And I was going to or C and I'm going to do two steps at a time for gonna actual on this side to everything this tool to get rice on one side of the equation. So I'm gonna add so so both side, and it's gonna before C is equal to dirty, too. We're gonna divide both sides by four to get see bites. So four divided by 36 is line for teeth equal to nine. We're gonna plug that incident equation tee. Times five is nine times five is 45. We're gonna subject for from him that is equal to 32. 33 and then we're gonna do nine waas 20. So amid a misty 2012 is actually 32. So these so t is actually equal to eight because three times 32 divided by four is eight. And we're gonna redo this one because so eight times five is 40 eight times five is sporting. And when we take away Whoa. 40 minus 12 is 28 is doing a So we're gonna do and we're gonna put in April. See here too. This is gonna be a plus 20 which is 28. We're gonna plug in eight for decide eight times three is 24 24. And as you see, this is obviously lower. It's gonna be lowered, indecent. Act together. So, you know, seek and also equal to eight. So for the sausages triangle there. Three possible answers for teeth, depending on how you put the sides which side before, which in just it depend on how you put your sides for the collateral. We know that all of the size has to equal to one thing. And from this, the signs don't equal the same thing One of them is You could get two of them to equal to each other so you can get rid of the size to be able to the same thing. So for the equilateral triangle, it's not possible. So not

James is flipping a coin twice. He says the probability that he’ll get tails both times is 1/2. Which of these is true?
James flipping the coin is an illustration of probability
James' claim is false
How to determine the true statement
The sample space of a coin is:
S = {H,T}
So, the probability of obtaining a tail is:
P(T) = n(T)/n(S)
This gives
P(T) = 1/2
When the coin is flipped twice, the probability that he’ll get tails both times is
P(T and T) = 1/2 * 1/2
Evaluate the product
P(T and T) = 1/4
From the question, he says the probability that he’ll get tails both times is 1/2.
Hence, James' claim is false

The measure of ∠H is 180 degrees, which is a straight angle.
What is a straight angle?An angle with a measure of exactly 180 degrees is called a straight angle. It is an angle with arms that point in opposing directions from the vertex and unites to make 180°.
The given measure of ∠H is (11x - 29).
To determine the measure of ∠H when x = 19, we can simply substitute x = 19 into the expression for the measure of ∠H:
∠H = 11x - 29
∠H = 11(19) - 29
∠H = 209 - 29
∠H = 180
Here, ∠H has a measure of 180 degrees, which is a straight angle.
Therefore, the measure of ∠H when x = 19 is 180 degrees.

if f(x) = 2 - x^1/2 and g(x) = x^2 – 9, what is the domain of g(x) divided f(x)?
~Shoto Todoroki here~
Let's consider what we are asked. The domain is defined as a set of points that satisfy the equation on the x-ordinate.
So, essentially, we need to find if and what the restriction on x is.
Let's now consider just f(x) because g(x) is completely irrelevant to the question.
f(x) = 2 - x^(1/2)
Since f(x) can never be 0 for a defined function, let's consider when f(x) = 0 to find a restriction on x.
2 - x^(1/2) = 0
2 = x^(1/2)
+-4 = x
But we can only take the positive 4 because inside a square root has to always be positive (unless you're dealing with complex numbers), so the only restriction is that x cannot be equal to 4.
Therefore, our domain is: x >= 0; x =/= 4hope this helps :D

Answer:
Little more than 5 years
Step-by-step explanation:
Given the following question:
Original value of the car is $14,000
18% depreciated or diminish in value per year.
How many years would it take for the cars value to reach $1000?
To find the answer we must first find 18% of the 14,000 speaking how that's how much the car value diminishes in a year.
18% of 14000:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{18\times14000}{100} =18\times14000=252000\div100=2520[/tex]
[tex]=2520[/tex]
18% of 14000 is 2520, which means each year the cars value depreciates $2520 dollars.
[tex]14000-2520=11480-2520=8960-2520-6440-2520=3920-2520=1400[/tex]
[tex]=1400[/tex]
Which means it will take a "little more than 5 years" for the cars value to reach $1000.

Your class is having a class picture taken on the lawn. The photographer is positioned 14 feet away from the center of the class. The photographer turns 50° to look at either end of the class.
a. What is the distance between the ends of the class? Round your answer to the nearest tenth.
The distance is about
feet.
b. The photographer turns another 10° either way to see the end of the camera range. If each student needs 2 feet of space, about how many more students can fit at the end of each row? Explain. Round answers to the nearest tenth when necessary.
About
more students can fit at the end of each row. The triangle formed by the
° angle has an opposite leg that is about
feet longer than the opposite leg of the triangle formed by the
° angle. Because each student needs 2 feet of space,
more students can fit on each end with about
feet of space left over.
Answer:
a) 33.4
b) About 3 students can fit at the end of each row. The triangle formed by the 60° angle has an opposite leg of that is about 7.5 feet longer than the opposite leg formed by the 50° angle. Because each students needs 2 feet of space, 3 more students can fit on each end with about 1.5 feet of space left over.
Step-by-step explanation:
A. I used the Tangent ratio which is opposite/adjacent
tan(50)=x/14
14*tan(50)=x
*Use you calculators here and you should get about 16.68, but this is only one of the right triangle, so multiply that by 2 and you should get about 33.36 which rounded should become 33.4
B. For the amount of students you can fit at the end of each row, you need to find how long the opposite leg of the 60° triangle is than the opposite leg of the 50° triangle. to do this use the tangent ratio
since the 60° triangle is a special triangle, the opposite side is 14√3
14√3 - (14 · tan(50) ≈ 7.56 ← the answer is 7.5 probably since they didn't round (in Big Ideas)
7.56/2 ≈ 3.78 ← 2 feet of space for each student
↑answer is just 3 since you cannot split living objects
The last answer is 1.5
the get the left over amount, we would have to take the length opposite leg of the 60° triangle and divide it by the length of the opposite leg of the 50° triangle
14√3 ÷ (14 · tan(50) ≈ 1.45 ← must use parentheses otherwise they will divide your answer by 14 and then multiply, which none of us wants.
