What is the measure of the exterior angle? Show all steps.

Answers

Answer:

108 degrees

Step-by-step explanation:

The thereom for this is the interior angles (a+10) and 44 degrees add up equaling to 2a. This works for any triangle like this. So, a+10+44=2a, and we solve for a to 54 for a. Then we insert a as 54 for 2a to get 54*2=108 degrees.

The answer is 108 degrees

Answer:

I know this is most likely a joke but I'll answer anyways :)

"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated.

Step-by-step explanation:

Remember that you flip the signs whenever you divide an inequality by a negative.

So here we divide both sides by negative four and then scan the signs to get

x ≥ -8

-4x ≤ 32
Divide both sides by 4 and flip the inequality sign
x ≥ -8 - C is the correct answer

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.

Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00

Answers

Answer:

y = a(.10) + 25

Step-by-step explanation:

Using the equation y = ax + b.

"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."

The word "per" indicating that you are multiplying this.

The only variables being multiplied are a and x.

Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.

Slope is defined as rise/run. Specifically, ((y2 - y1)/x2 - x1))- To define slope, we read the graph from right to left. Pick two points on the graph. I’ll pick the following two points:

(-2,13) and (0,5)

Applying the above formula will get you ((13-5)/(-2-0)) = 8/-2= -4
-4 is the slope

The y-intercept is the y-value where the line crosses the y axis. In this function, the y-intercept is 5.

The slope intercept form can be written in the form: y = mx + b where m is the slope and b is the y-intercept. Therefore, substitution of the values we’ve got will give us the following answer:

y = -4x + 5

Solve for x. Round to the nearest tenth, if necessary.

Answers

Answer:

[tex]\sqrt19[/tex]

Step-by-step explanation:

First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,

9^2 + b^2 = 10^2.

solve, 81 + b^2 = 100

then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].

Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.

4^2 + x^2 = 19.

Solve

16 + x^2 = 19

Subtract 16 from both sides

x^2 = 19

and finally, we take the square root of both sides

x = [tex]\sqrt19[/tex]

Square root of 19 would be your answer

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.

Answers

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

equation: 20/c= 3.00c
