I have to assume that someone goes into the store and buys 3 pens for $1.50, 8 for $4 and 12 for $6.  This is a bit confusing until you verify that the unit cost per pen is the same in all three cases.

3 pens for $1.50 comes out to $0.50 per pen;
8 pens for $4 comes out to $0.50 per pen; and 
12 pens for $6 comes out to $0.50 per pen.

Summarizing:  c = ($0.50)p

Will literally make BRAINLIEST and marry you if you do this for me
Tanya [424]

Answer:

0.44

Step-by-step explanation:

See the picture below.

Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.

Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.

For angle J, leg LK is the opposite leg.

The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.

\sin J = \dfrac{opposite~leg}{hypotenuse}

\sin J = \dfrac{39}{89}

\sin J = 0.43820...

Answer: 0.44

Lets say you have 5 apples, but the you give away 3 of them.
To work how many you have left you take away.
5-3 = 2

Lets apply this with fractions now.
You have 9/7 yard, but then you give away 7/20 yard.
Now you take them away:
9/7 minus 7/20 = 131/140

Hope this helps :)

Geometry proofs<br> help me please :)
REY [17]

Answer:

2) Right angles always equal 90°

3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.

4) Removing the m and replacing with the congruent symbol.

I'm not too sure how this goes but it should be something like that.
