Classify the triangle by its angles.
Answer:
D. obtuse
Step-by-step explanation:
The largest angle tells you the sort of triangle it is. Here, the largest angle is more than 90°, so the triangle is classified as obtuse.
__
If it were exactly 90°, the triangle would be a right triangle. A largest angle less than 90° means the triangle is an acute triangle.
_____
Additional comment
The two angles opposite the obtuse angle have the same measure. That means the triangle can be further classified as isosceles. In an equilateral triangle, all three angles have the same measure: 60°.
Whole numbers that go one after another are called consecutive numbers. If you add 4 consecutive numbers, you get the smallest of these numbers multiplied by 5. What is this smallest number?
Answer:
The smallest number be 6.
Step-by-step explanation:
Let the 4 consecutive numbers be :
n,n+1,n+2,n+3 where n is the smallest number
Adding up the 4 consecutive numbers, we get :
n+n+1+n+2+n+3 = 4n+6
ATQ,
4n+6 = 5n
Taking like terms together,
6=5n-4n
⇒ n = 6
So, the smallest number be 6.

Question 1aa
Given: B = 10°, C = 100°, b = 2
10° + 100° + A = 180°

Question 2bb
Given: A = 40°, B = 40°, c = 2
40° + 40° + C = 180°
⇒ C = 100°
[tex]\dfrac{a}{\sin 40}=\dfrac{b}{\sin 40}=\dfrac{2}{\sin 100}[/tex]
[tex]\implies a=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]
[tex]\implies b=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]

Question 1aa
Given: A = 110°, C = 30°, c = 2
110° + 30° + B = 180°
⇒ B = 40°
[tex]\dfrac{a}{\sin 110}=\dfrac{b}{\sin 40}=\dfrac{3}{\sin 30}[/tex]
[tex]\implies a=\sin 110 \cdot \dfrac{3}{\sin 30}=5.638155725...[/tex]

Step-by-step explanation:
Under her cell phone plan, Micaela pays a flat cost of $47 per month and $5 per gigabyte. She wants to keep her bill at $68.50 per month. Write and solve an equation which can be used to determine xx, the number of gigabytes of data Micaela can use while staying within her budget.
Answer:
≤ 4.3 gigabytes
Step-by-step explanation:
Flat fee + cost for x gigabytes = her budget
47 + 5 * x ≤ 68.50
5x = 68.50 - 47 ≤ 21.50
x ≤ 21.50/5 = 4.3 gigabytes
Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.
Let, "x" to represent the number of gigabytes of data Micaela can use while staying within her budget.
The total cost can be calculated by adding the flat cost of $47 to the cost based on the gigabytes used ($5 per gigabyte):
Total Cost = Flat Cost + (Cost per Gigabyte * Number of Gigabytes)
Given that Micaela wants to keep her bill at $68.50 per month, we can set up the equation:
68.50 = 47 + 5x
Now, solve for x:
68.50 - 47 = 5x
21.50 = 5x
Divide both sides by 5:
x = 21.50 / 5
x = 4.3
So, Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Step-by-step explanation:
sin = opp/hyp
The opposite side to angle A is side BC, which has a length of 60.
The hypotenuse is AB, which we can find the length of using the Pythagorean theorem. Using the Pythagorean theorem, we get that AB=100.
So the sine of A = 60/100 = 3/5

15-18 10
19-22 8
23-26 9
27-30 4
31-34 4
35-38 5
Using it's concept, it is found that the relative frequency for the class with a lower class limit of 35 is of 12.5%.
What is a relative frequency?A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, 5 out of a total of 10 + 8 + 9 + 4 + 4 + 5 = 40 students are in the class with a lower class limit of 35, hence:
f = 5/40 = 1/8 = 0.125 = 12.5%.

what is the answer to 15x+6y
Answer:
x = -0.4y
Step-by-step explanation:
Simplifying
15x + 6y = 0
Solving
15x + 6y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
15x + 6y + -6y = 0 + -6y
Combine like terms: 6y + -6y = 0
15x + 0 = 0 + -6y
15x = 0 + -6y
Remove the zero:
15x = -6y
Divide each side by '15'.
x = -0.4y

Why is a convergent and b divergent?
Part (a)
This sequence is convergent because all we care about are the leading terms for the numerator and denominator. As n gets really large, the leading terms dictate what happens.
The leading term up top is 9n
The leading term down below is 7n
Divide the two items to get (9n)/(7n) = 9/7
We don't have to worry about dividing by zero because n will go off to infinity, and as it does so, the sequence [tex]\{a_n\}[/tex] converges to 9/7
========================================================
Part (b)
As n heads to infinity, the terms of the sequence are approaching 9/7 (they never quite hit the exact value though).
Note how 9/7 = 1.2857 approximately which is larger than 0
So effectively for very large values of n, we're adding on 1.2857 each time or close to it, meaning that this infinite series diverges.
------
For a series like this to converge, the answer to part (a) must be 0. This way at some point, we're effectively adding 0 to the series and we approach some fixed sum.
For example, consider the sequence 1/(7n+1)
As n goes to infinity, the terms of the sequence approach 0
This means that for some very large n, the 1/(7n+1) is basically 0 and we aren't adding much onto the sum to change it. So this sum will converge to a fixed value.

Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
