His grade increased. 
If you divide 13 by 17, you get 0.7647, and if you multiply that by 100, that's 76.47%, which was is grade on the test.
If you divide 12 by 15, you get 0.8, or 80%.

Answer:

y = 9\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{9}{y}

Multiply both sides by y

y × sin45° = 9, that is

y × \frac{1}{\sqrt{2} } = 9

Multiply both sides by \sqrt{2}

y = 9\sqrt{2}

Megan went to the beach 34 times last summer. She went 6 more times in July than she did in June. She went twice as many times i
Irina-Kira [14]
<span>Megan went to beach 34 times last summer.
June =  x
July = 6 * june
August =  2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
