A side of the triangle below has been extended to form an exterior angle of 164". Find
the value of x.
1649

Answers

Given:

Measure of exterior angle = 164°

The measure of opposite interior angles are x° and 53°.

To find:

The value of x.

Solution:

According to the Exterior Angle Theorem, in a triangle the measure of an exterior angles is always equal to the sum of measures of two opposite interior angles.

Using Exterior Angle Theorem, we get

[tex]x^\circ+53^\circ=164^\circ[/tex]

[tex]x^\circ=164^\circ-53^\circ[/tex]

[tex]x^\circ=111^\circ[/tex]

[tex]x=111[/tex]

Therefore, the value of x is 111.

“How many 2/5 are in 1?”

I love the easy ones!

The real math folks generally ignore them I guess because the easy ones are not worth their time, leaving said easy ones to dilettantes like me, who then look smarter-than-I-really-am to the noobies.

Love the easy ones.

So, to the question: How many two-fifths are in one?

Well now. How shall we handle this? Hmm…

I know! Let's count the fifths (just numbers, no booze), because it's probably as good a way of getting to an answer as any other way, the question is about fifths, and counting the fifths will at least give us a picture of what we're dealing with here.

Let's jump ahead, to see where we want to end up:

We want to end up with five fifths, also known as 5/5, because 5/5 is the same as 1. How do I know that 5/5 is the same as 1? Well, I know (you'll just have to trust me on this) because saying “5/5” is the same as saying “5 divided by 5”, and saying “1/2” is the same as saying “1 divided by 2", and so on. This is true for all fractions.

So: if 5/5 is the same as 5 divided by 5, then 5/5 equals 1. (You can see why, right? Any number divided into itself is equal to one; also, five goes into five exactly one time!).

And counting the fifths,

1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 = 1

Or, to count them another way,

1/5 + 1/5 = 2/5

2/5 + 1/5 = 3/5

3/5 + 1/5 = 4/5

4/5 + 1/5 = 5/5

Now that we can see what's inside of that 5/5, let's count how many two-fifths are in five-fifths by adding 2/5 together until we get as close to 5/5 as possible without going over:

2/5 + 2/5 = 4/5

leaving just 1/5 remainder, meaning that there are two 2/5 in 5/5.

We can see that that is true and correct by looking at our little counting exercise above.

Now to make sure our reasoning is clear let's count our fifths again, this time slightly rearranging the way we write the numbers, and then taking things one step further:

(1/5 + 1/5) + (1/5 + 1/5) + 1/5 = 5/5

(2/5) + (2/5) + (1/5) = 5/5

And there it is: there are two 2/5 in 1!

So let's complete the addition for the sake of those like myself who need to see these things through to their furthest conclusion:

(2/5) + (2/5) + (1/5) = 5/5

4/5 + 1/5 = 5/5

5/5 = 5/5

5/5 = 1

1 = 1. And 2/5+2/5=4/5.

Help pls and thank you :)

Answer:

[tex]y=\frac{-2}{3} x+1[/tex]

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex]. Here's what the variables mean:

y = the y-coordinate

m = the slope

x = the x=coordinate

b = the y-intercept (what y is equal to when the line crosses the y-axis)

First, we need to calculate the slope of the line (m). The slope is the [tex]\frac{rise}{run}[/tex] of the line, or in other words, the change in y over the change in x. We can find this by just looking at the graph, between the two given points. For 3 spaces the line travels to the right, it travels downward 2 spaces. Therefore, the slope of the line is [tex]\frac{-2}{3}[/tex].

We can also calculate this using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] by using two points that fall on the line, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Here, we can use the points (-3,3) and (0,1).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\frac{1-3}{0-(-3)}[/tex]

Two negatives make a positive

[tex]=\frac{1-3}{0+3}\\=\frac{-2}{3}[/tex]

Then, we need to find the y-intercept of the line (b). We can find this by, again, looking at the graph. The line crosses the y-axis when y is equal to 1, so the y-intercept of the line is 1.

Now, we plug our calculated values back into the original equation:

[tex]y=mx+b\\y=\frac{-2}{3} x+1[/tex]

I hope this helps!

Robin saves $500 at a yearly simple interest rate of 4%. What is the total amount of money she has after 20 years?

Answers

Answer:

Use the equation 500x0.04x20 and then 500x20 and add the sums up and get 10,400 i believe is im wrong sorry :/

$900 is the total amount of money she has after 20 years.

What is simple interest?

Simple interest is, by definition, the amount of interest paid on a specific principal sum of money when an interest rate is applied. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

From the formula of simple interest A = P(1 + rt)

Where A = amount earned

P = principal amount

r = rate of interest

t = time

In our case

P = 500

r = 4%

t = 20

Thus,

Amount earned after 20 years = 500(1 + 4*20/100)

Amount earned after 20 years = 500(1 + 4/5)

Amount earned after 20 years = 900

therefore, the total amount of money she has after 20 years is $900.

Explain and Show the equation of line perpendicular to y=-1x+2 going through the point (6, 3)

Answers

Answer:

y = x-3 is the equation

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

The general equation form of a straight line is;

y = mx + b

Fro the equation;

y = -1x + 2

The slope is -1

So the equation of the perpendicular line is as follows;

-1 * m = -1

m = 1

so we can use the point-slope equation form

That would be:

y-y1 = m(x-x1)

y-3 = 1(x-6)

y-3 = x-6

y = x-6+3

y = x-3

The US controlled trade in much of the Western Hemisphere, and used their immense military power to police trade in the region. The phrase, as depicted in the cartoon, speak softly and carry a big stick, means that America should negotiate, but also show that they have a lot of military strength, without actually doing anything, unless absolutely necessary. B) One similar way trade was organized in the same time period to benefit Europe was that European powers used their military strength to pressure other countries into trading with them. This was similar to the big stick policy, but they established colonies and controlled trade through that. European powers also forced Asian countries to establish ports so that they could trade there. The fundamental principles of both the American big stick policy and its European counterpart are the same, as they control trade in the regions they want to trade in with their military strength and influence. C) One consequence of this for one of the examples used in problem A is that American merchants and companies were able to have a lot of economic control in other regions, and their profits increased as they gained more control of trade in the regions they aimed to control. With economic control of a region, also comes a certain degree of political control, so many US companies used their control to influence political decisions in their favor. For example, the United Fruit Company used their economic control over some portions of South America, and inhibited the development of countries in South America like Guatemala.
