Help me w this multiple choice!

olga2289 [7]

Answer:

Step-by-step explanation:

$\sin(30) = \frac{n}{ \frac{10 \sqrt{3} }{3} } \\ 0.5 = \frac{n}{5.77} \\ n = 2.88 = \frac{5 \sqrt{3} }{3}$

$\cos(30) = \frac{m}{ \frac{10 \sqrt{3} }{3} } \\ 0.866 = \frac{m}{5.77} \\ m = 5$

Slove the simoltanous equation by using substitution or elimination method 5x-3y=1 3x+2y=1<br>

xxTIMURxx [149]

<u>By substitution method </u>

5x - 3y =1

3x + 2y = 1

_____o____o____

$5x - 3y = 1 \\ 5x = 1 + 3y \\ x = \frac{1 + 3y}{5}$

______o____o_____

$3x + 2y = 1 \\ 3( \frac{1 + 3y}{5} ) + 2y = 1 \\ \frac{3 + 9y}{5} + 2y = 1 \\ \frac{3 +9y + 10y}{5} = 1 \\ \frac{3 + 19y}{5} = 1 \\ 3 + 19y = (1)(5) \\ 3 + 19y = 5 \\ 19y = 5 - 3 \\ 19y = 2 \\ y = \frac{2}{19}$

______o_____o____

$x = \frac{1 + 3y}{5} = \frac{1 + 3 \frac{2}{19} }{5} \\ x = \frac{1 + \frac{6}{19} }{5} = \frac{ \frac{19 + 6}{19} }{5} = \frac{ \frac{25}{19} }{5} \\ x = \frac{25}{19} \div 5 \\ x = \frac{25}{19} \times \frac{1}{5} \\ x = \frac{5}{19}$

I hope I helped you^_^

Erica spent 1/3 of her money on a pack of pens 1/2 of her money on a pack of markers and 1/8 of her money on a pack of pencils w

iogann1982 [59]

Find common denominator first.
Looks like 24. So 3/24 + 12/24 + 4/24 = 19/24 spent.

So the remainder would be 5/24.

Oliver injured his leg while playing football. Fortunately, he has a health insurance policy. He has a deductible of $2,000, and

yKpoI14uk [10]

Answer:

The Answer is:

Step-by-step explanation:

First, find the 20% that he must pay:

$3,500 * .20 = $700.

The remaining balance is:

$3,500 - $700 = $2,800

He already paid $1,000 of his deductible of $2,000. He has $1,000 left to pay.

Add that to the $700 to get:

$1,000 + $700 = $1,700 out of pocket.
