Step-by-step explanation:

Since we have one angle with an opposite side and another side known, we are dealing with an ambiguous case. There are either

0

or

solutions to this triangle.

We start by determining the measure of

using the law of Sines, since we already know the measure of side

There is only one solution to this triangle, because if it was, then the alternative measure of A would be

=

, which when added to

B

We can now use the measure of angles

Answers

Answer:

x = 11

Step-by-step explanation:

Since we are given triangle PQR is similar to triangle PTU, we can write a proportion to connect the side lengths:

PQ / PT = QR / TU = PR / PU

We don't really care about QR and TU because the are irrelevant to the problem, so we can remove them:

PQ / PT = PR / PU

Now, we can substitute the values given by the diagram:

70 / 30 = 49 / (x + 10)

We can cross multiply,

70(x + 10) = 30 * 49

And divide by 70 on both sides(too lazy to multiply :P)

x + 10 = 3 * 7

x + 10 = 21

x = 11

Answer:

y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = S (- 9, 8) and (x₂, y₂ ) = G (- 3, 3)

m = [tex]\frac{3-8}{-3+9}[/tex] = - [tex]\frac{5}{6}[/tex] , then

y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 3 ), then

3 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{5}{2}[/tex] = [tex]\frac{1}{2}[/tex]

y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex] ← equation of line

bag of candy contains 4 strawberry

minutes later selects another and eats
that one as well, what is the probability
that they were both orange flavored
gumdrops? Leave answer as a fraction in simplest form.

Answers

There are 9 candies in total, with 5 being orange. Think of it. For the first grab, you have a 5/9 chance of it being orange flavored. Now there are 4 orange flavored candies, and 8 total candies in the bag. Grabbing a second candy, Billy has a 4/8 chance of grabbing an orange flavored candy. So your two fractions are...

5/9, 4/8

Can you combine these two fractions for a final answer?

Solve for f: 6f + 9g = 3g + f

f = f equals StartFraction negative 8 g Over 3 EndFraction.
f = f equals StartFraction negative 6 g Over 5 EndFraction.
f = f equals StartFraction negative 5 g Over 6 EndFraction.
f = f equals StartFraction 12 g Over 7 EndFraction.

Answers

Answer:

f = -6g/5

Step-by-step explanation:

6f + 9g = 3g + f

combine like terms

6f -f = 3g - 9g

5f = -6g

divide both sides of the equation by 5

f = -6g/5

A flower box is 3 ft. Long, 2 3/4 ft. Wide, and 1/2 ft. Deep. How many cubic feet of dirt can it hold? A. 4 1/8 B. 5 3/4 C. 6 1/2 D. 6 3/8

Answers

Answer:

The box can hold 4 1/8 cubic feet of dirt

Step-by-step explanation:

What we simply have to find here is the volume of dirt it can take

To get this, we have to multiply the dimensions of the box

We have this as follows

Volume or box = length * width * height

Volume of box = 2 3/4 * 1/2 * 3

Volume of box = 11/4 * 3 * 1/2 = 33/8 = 4 1/8 cubic feet

Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?

A. Graph A
B. Graph B
C. Graph C
D. Graph D

Answers

Answer:

B

Step-by-step explanation:

Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.

B. Graph B

Answers

Answer:The 36Th Term is 683

Step-by-step explanation:

The nth term of an Ap Is given as

an = a1 + (n - 1 ) d.

Now the first term a1=403

and the common difference,d=403-395=8

The 36th term will now be

a₃₆ = a1 + (n - 1 ) d

a₃₆ = 403 + (36 - 1 ) 8

a₃₆ = 403 + (35 ) 8

a₃₆ = 403 +280

a₃₆ = 683

The 5th term of the sequence is 3200 therefore the correct option is option D.

Sequence

A sequence is a collection of numbers (or other items such as geometric objects) that follow a pattern or function.

How to find 5th term of this sequence?

The function for a sequence is f(n) [tex]=200\times2^{n-1}[/tex]

Where n represents the term.

So for the 5th term

f(5) [tex]=200\times2^{5-1}\\[/tex]

     [tex]=200\times2^{4}[/tex]

     = 200 × 16

     = 3200

Hence the 5th term of the sequence is 3200.

Again, this is a first-time event, a breakthrough, and that's why I believe this treaty will not only lessen the threat of war, it can also speed along a process that may someday remove that threat entirely.Indeed, this treaty, and all that we've achieved during this summit, signals a broader understanding between the United States and the Soviet Union. B) It is an understanding that will help keep the peace as we work toward the ultimate goal of our foreign policy: a world where the people of every land can decide for themselves their form of government and way of life.Yet as important as the INF treaty is, there is a further and even more crucial point about the last 3 days and the entire summit process: Soviet-American relations are no longer focused only on arms control issues. They now cover a far broader agenda, one that has, at its root, realism and candor. C) Let me explain this with a saying I've often repeated: Nations do not distrust each other because they're armed; they are armed because they distrust each other. And just as real peace means the presence of freedom and justice as well as the absence of war, so, too, summits must be discussions not just about arms but about the fundamental differences that cause nations to be armed.Dealing then with the deeper sources of conflict between nations and systems of government is a practical and moral imperative. D) And that's why it was vital to establish a broader summit agenda, one that dealt not only with arms reductions but also people-to-people contacts between our nations and, most important, the issues of human rights and regional conflicts.
