Answer:

16.5 hours

Step-by-step explanation:

The bicycle costs $240. Eva already has $42. She is making $12 per hour.

240 = 12x + 42

Solve for x to find out how many hours Eva needs to work to buy the bicycle.

240 = 12x + 42

240 - 42 = (12x + 42) - 42

198 = 12x

198/12 = (12x)/12

16.5 = x

Eva needs to work 16.5 hours to be able to buy the bikw.

WILL MARK BRAINLIST!!What is the measure of one interior angle in a regular pentagon?

never [62]

The answer is 108°

A regular pentagon has all its five sides equal and all five angles are also equal. Hence, the measure of each interior angle of a regular pentagon is given by the below formula. Measure of each interior angle = [(n – 2) × 180°]/n = 540°/5 = 108°.

!50 point question! Find x and explain how you found it!

STatiana [176]

<u>Answer:</u>

$\sf x = 60^{\circ \:}$

<u>given:</u>

adjacent side: 10
hypotenuse side: 20

<u>using cosine rule:</u>

$\hookrightarrow \sf cos(x) = \dfrac{adjacent}{hypotense}$

$\hookrightarrow \sf \sf cos(x) = \dfrac{10}{20}$

$\hookrightarrow \sf \sf x = cos^{-1}(\dfrac{10}{20} )$

$\hookrightarrow \sf \sf x = 60^{\circ \:}$

Use the distance formula to find the perimeter of the triangle below. Round you answer to the nearest hundredth.

Murrr4er [49]

<u>jAlright, let's take this problem step-by-step</u>:

<u>What is the perimeter</u>:

⇒ all the side-lengths added up

⇒ <em>need</em> to find side-length using distance formula

$Distance_._. Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

- (x₁,y₁): first point

- (x₂,y₂): second point

<u>Let's solve</u>:

Find length of <em>AC</em>

⇒ <em>first point</em>: (5,7)

<em> ⇒ second point: </em>(3,3)

<em> </em> $Distance =\sqrt{(3-5)^2+(3-7)^2} =\sqrt{4+16} =\sqrt{20} =4.472$

Find length of AB

⇒ <em>first point:</em> (5,7)

<em> ⇒ second point:</em>(8,6)

<em> </em> $Distance=\sqrt{(8-5)^2+(6-7)^2} =\sqrt{9+1} =\sqrt{10}=3.162$

Find length of BC

⇒<em> first point: </em>(8,6)

<em> ⇒ second point: </em>(3,3)

<em> </em> $Distance = \sqrt{(3-8)^2+(3-6)^2} =\sqrt{25+9} =\sqrt{34}=5.831$

<u>Now let's solve for the perimeter</u>:

$Perimeter = 4.472+ 3.126+ 5.831=13.429$

<u>Answer: 13.43</u> (<em>rounded to the nearest hundredth)</em>

Hope that helps!
