Answer:

<u>AC</u><u> </u><u>i</u><u>s</u><u> </u><u>6</u><u>.</u><u>5</u><u> </u><u>cm</u>

Step-by-step explanation:

From trigonometric ratios:

\sin( \theta)  =  \frac{opposite}{hypotenuse}  \\

opposite » 3 cm

hypotenuse » AC

angle » 28°

\sin(28 \degree)  =  \frac{3}{AC}  \\  \\ AC =  \frac{3}{ \sin(28 \degree) }  \\  \\ AC =  \frac{3}{0.46}  \\  \\ AC = 6.5 \: cm

A hungry elf ate 35 of your muffins. That was 710 of all of them! With how many did you start?
KengaRu [80]

Answer:

2094.5 muffins

Step-by-step explanation:

The problem is a little bit messy, but i’m guessing you meant that the elf ate 35% of the muffins, which 35% is 710 muffins. so since 35% of muffins is 710 muffins, let’s multiply that by 2 so we can get 70%.

so 710 x 2 is 1420. so 70% of the muffins is 1420 muffins! sadly that’s not all of the muffins. we’re still missing another 30%. since we don’t know how many muffins are in 30%, let’s just take 710 muffins - 5%. when you do that you get 674.5. so now that we know how much is in 30%, let’s take 1420 + 674.5. when you do that you get 2094.5! so you started off with 2094 and a half muffins!
