Please Help! Due tonight! Solve the triangle. Round to nearest tenth, if necessary.
Answer:
[tex]\displaystyle 33,8 ≈ b \\ 55,1 ≈ a \\ 35° = m∠B[/tex]
Step-by-step explanation:
We will be using the Law of Sines to find edges b and a one at a time, therefore we will use the given variables in the formulas:
Solving for Angles:
[tex]\displaystyle \frac{sin∠C}{c} = \frac{sin∠B}{b} = \frac{sin∠A}{a}[/tex]
**Use [tex]\displaystyle arcsin\:or\:sin^{-1}[/tex]in your solution or you will throw the result off!
Solving for Edges:
[tex]\displaystyle \frac{c}{sin∠C} = \frac{b}{sin∠B} = \frac{a}{sin∠A}[/tex]
__________________________________________________________
[tex]\displaystyle \frac{33}{sin\:34} = \frac{b}{sin\:35} \hookrightarrow \frac{33sin\:35}{sin\:34} = b \hookrightarrow 33,848824408... = b \\ \\ 33,8 ≈ b[/tex]
We will now define edge a:
[tex]\displaystyle \frac{33}{sin\:34} = \frac{a}{sin\:111} \hookrightarrow \frac{33sin\:111}{sin\:34} = a \hookrightarrow 55,093964682... = a \\ \\ 55,1 ≈ a[/tex]
This triangle is now deemed solved.
***The fact that you solved for the [tex]\displaystyle m∠B[/tex]tells me that you understood what to when it comes to the interior angles of triangles, so I did not have to cover that. Good wourk citisen!
I am delighted to assist you at any time. If you have further questions though, comment them and I will do my very best to answer them.

Triangle ABC is isosceles. It is reflected across the y- axis and then translated up 1 unit to form triangle ABC.
Answer: True, True, True
Step-by-step explanation:
A. True. Angles B and C are congruent, and since B' is congruent to B, by the transitive property, C is congruent to B', and thus has the same measure.
B. True. AB>BC, and the rigid motions won't change the side lengths.
C. True for the same reason in B.
If B varies directly to C and inversely to the cube of D, and B = 5 when C = 2 and D = 1, find B when C = 4 and D = 2
Answer:
5/4
Step-by-step explanation:
B = kC/D³
Given B = 5, C = 2, D = 1
so 5 = k(2)/1³ = 2k, k = 5/2 = 2.5
B = 2.5C/D³
when C = 4, D = 2
B = 2.5 * 4/2³ = 10/8 = 5/4

Answer:
The answer is 1920 cm
Step-by-step explanation:
First we need to break up to two separate shapes. These shapes are both rectangles, one on the right and one on the left.
To find the volume of a Prism, the equation is V=lwh (length x width x height).
So by splitting up the shape we have two different equation
V= (10)(8)(14) =1120
V= (10)(8)(10)=800
Now we add 1120+800 to get the volume of the entire shape, which is 1920 cm.

MARKINF BRAINLIEST AND 50 POINTS6. The Gonzales family has three children.
On summer break, they went to an amusement
park. They bought 3 child tickets for $18.50
and 2 adult tickets. If they spent a total of
$ 104.50, how much was the price of each
adult ticket?
PLEASE WRITE THE EQUATION AND SOLUTION!!!!
Answer:
the price of each adult ticket is $43
Step-by-step explanation:
Let's say the price for 1 adult ticket is x and the price for 1 child ticket is y
3y = 18.5 and 3y + 2x = 104.50
2x + 18.5 = 104.50
2x = 104.5 - 18.50
2x = 86
x = [tex]\frac{86}{2}[/tex]
x = 43
So the price for 1 adult ticket is $43
Answer:
Let's say the price for 1 adult ticket is x and price for 1 child ticket is y
3y = 18.5 and 3y + 2x = 104.5
<=> 2x + 18.5 = 104.5
<=> 2x = 104.5 - 18.5
<=> 2x = 86
<=> x = 86 / 2
<=> x = 43
So the price for 1 adult ticket is $43

The hypotenuse of a 30°-60°-90° triangle measures 8√3 inches. What is the length of the shorter leg?
Answer: 8 inches
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the short side to the long side is 1/sqrt(3).
Therefore the short side is the long side divided by sqrt(3).
So the short side = 8 sqrt(3)/sqrt(3) = 8 inches

Write an explicit formula for an, the nth term
of the sequence 11, 2, -7
Answer:
b(n) = 15 - 7(n - 1)
Step-by-step explanation:
Answer:
aₙ = 11 - 9(n - 1)
Step-by-step explanation:
2 - 11 = (-7) - 2 = -9
So it is an arithmetic sequence
a₁ = 11
a₂ = 2 = 11 + (-9) = 11 + (2 - 1)*(-9)
a₃ = -7 = 2 + (-9) = 11 + (-9) + (-9) = 11 + (3 - 1)*(-9)
.....
aₙ = 11 + (n - 1) * (-9)
or
aₙ = 11 - 9(n - 1)

Determine the solution to the system of equations graphed below and explain your reasoning in complete sentences.
Answer:
(1, 5)
Step-by-step explanation:
The solution to the system of equations is the point of intersection of the two lines. From inspection of the graph, the point of intersection is at (1, 5).
Proof
The solution to a system of equations is the point at which the two lines meet.
⇒ g(x) = f(x)
⇒ 3x + 2 = |x - 4| + 2
⇒ 3x = |x - 4|
⇒ 3x = x - 4 and 3x = -(x - 4)
⇒ 3x = x - 4
⇒ 2x = -4
⇒ x = -2
Inputting x = -2 into the 2 equations:
⇒ g(-2) = 3 · -2 + 2 = -4
⇒ f(-2) = |-2 - 4| + 2 = 8
Therefore, as the y-values are different, x = -2 is NOT a solution
⇒ 3x = -(x - 4)
⇒ 3x = 4 - x
⇒ 4x = 4
⇒ x = 1
Inputting x = 1 into the 2 equations:
⇒ g(1) = 3 · 1 + 2 = 5
⇒ f(1) = |1 - 4| + 2 = 5
Therefore, as the y-values are the same, x = 1 IS a solution
and the solution is (1, 5)
11) Tickets to a concert cost either $15 or
$20. A total of 300 tickets were sold and
the total receipts were $5300. How many
of each kind of ticket were sold.
Answer:
There were 140 tickets sold that cost $15 and 160 tickets sold that cost $20.
Step-by-step explanation:
To solve this problem, we should create a system of equations. Let's let the variable x represent the number of $15 tickets sold and let the variable y represent the number of $20 tickets sold. Using these variables, we can make the following equations:
x + y = 300
15x + 20y = 5300
To solve this equation, we can use substitution. Our first step in this case is solving the first equation for one variable; let's choose x.
x = 300 - y
Now, we can substitute this value for x into the second equation.
15(300-y) + 20y = 5300
Next we can distribute through the parentheses on the left side of the equation.
4500 - 15y + 20y = 5300
We can combine like terms on the left side of the equation to simplify.
4500 + 5y = 5300
We should then subtract 4500 from both sides of the equation.
5y = 800
Finally, we can divide both sides of the equation by 5.
y = 160
To solve for x, we can substitute this value for y into either of our original equations, but we should probably choose the first one for simplicity.
x + y = 300
x + 160 = 300
x = 140
Therefore, x = 140 and y = 160; this means that 140 $15 tickets were sold and 160 $20 tickets were sold.
Hope this helps!

The price the school district pays for each typewriter is $106.56.
What is the price for each typewriter?A quantity discount is the discount given for bulk purchases. It reduces the purchase price of a good or service.
Total purchase price of the typewriters before the discount = (50 x 129.95) = 6,497.50
Total purchase price of the typewriters after the discount = (100 - 18) x 6,497.50
