Hey there!

1/5 + 3/10
= 2/10 + 3/10

= 2 + 3/10 - 0

= 5/10

= 5 ÷ 5 / 10 ÷ 5

= 1 / 2

Therefore, your answer is: 1/2

Good luck on your assignment & enjoy your day!

If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (ie. 30° north

Klio2033 [76]

Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

<u>Step-by-step explanation:</u>

Here we have , If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (i.e. 30° north of east) . We need yo find how far does it go in the y direction (north), and how far does it go in the x direction (east). Let's find out:

According to question we have a right angle triangle as :

$Hypotenuse =13m\\x=\frac{\pi}{6} =30$

x direction (east)

We know that ,

⇒ $cosx = \frac{Base}{Hypotenuse}$

⇒ $cos30 = \frac{Base}{13}$

⇒ $\frac{\sqrt{3} }{2} = \frac{Base}{13}$

⇒ $Base=\frac{\sqrt{3}(13) }{2} m$

⇒ $Base=11.2583303m$

y direction (North )

We know that ,

⇒ $sinx = \frac{Perpendicular}{Hypotenuse}$

⇒ $sin30 = \frac{Perpendicular}{13}$

⇒ $\frac{1}{2} = \frac{Perpendicular}{13}$

⇒ $Perpendicular=7.5m$

Therefore , Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

fiasKO [112]

<h3>Answer: 7/19</h3>

Explanation:

There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total

The probability of selecting blue is therefore 7/19

We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.

You are making several purchases from the I.B. Electric electronics store. You can buy from this store online or in a physical s

hammer [34]

Answer:

Online store will save the most money

Step-by-step explanation:

<u>Amount used in Physical store</u>

Batteries 2packs @$5.99 cost = $5.99*2=$11.98

Stereo 1 system @$100 cost = $100*1=$100

CDs 3 CDs @$7.95 cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =<u>$ 122.25</u>

Applying sale tax 5% = 105/100 * 122.25=<u>$128.36</u>

Amount to spend when using physical store= $128.36

<u>Now</u><u> </u><u>calculate for the online store</u>

Batteries 2packs @$4.99 cost= $4.99*2=$ 9.98

Stereo 1 system @$90 cost= $ 90 *1= $90

CDs 3 CDs @$8.95 cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=<u>0.88</u>
