7 0

Answer:

Things like:

2/9 + 7/9  = 9/9 = 1

3/4 + 1/4 = 4/4 = 1

If the number is the same for the numerator and denominator it adds up to 1.

More examples:

6/10 + 4/10 = 10/10 = 1

9/15 + 6/15 = 15/15 = 1

The table shows the Grades that students received on a test what fraction of the students scored an A or B on the test
Triss [41]
Okay. So, 15% is 15/100 and 33% is 33/100. 15 + 33 is 48. You leave the denominator the same, so the fraction is 48/100. However, the fraction needs to be simplified. Whatever you do to the numerator, we must do to the denominator. We can divide both numbers by 4 to get the simplified fraction form. 48/4 is 12. 100/4 is 25. There. The simplified fraction is 12/25. The answer is H: 12/25.

Identify the values of the variables. Give your answers in simplest radical form. HELP PLEASE!!!
galben [10]

Answer:

x = 3\sqrt{2}

y = 6\sqrt{2}

Step-by-step explanation:

The triangle is a 30-60-90 right triangle.

The ratio of the lengths of the sides is:

1 : \sqrt{3} : 2

The order of the sides in the ratio above is

short leg : long leg : hypotenuse

The long leg is sqrt(3) times the length of the short leg.

x \times \sqrt{3} = 3\sqrt{6}

x = \dfrac{3\sqrt{6}}{\sqrt{3}}

x = 3 \times \sqrt{\dfrac{6}{3}}

x = 3\sqrt{2}

The hypotenuse is twice the length of the short leg.

y = 2 \times 3\sqrt{2}

y = 6\sqrt{2}
