9 / 16 + 1/2 = ?

Step 1. In adding fractions, denominators must be the same. As we can see the denominators are 16 and 2. We observe that 16 is 8 times bigger than 2. Therefore, we must multiply 1/2 by 8 to get the same denominator.

(1 * 8) / (2 * 8) = 8 / 16

Step 2.  Add the numerators and put them over the same denominator.

9/16 + 8/16 = (9+8) / 16 = 17 / 16

Step 3. Simplify the fractions. (If needed)

As you can see, 17/16 is in its simplest form. Thus, 9/16 + 1/2 = 17/16

If you would like to add and simplify 9/16 and 1/2, you can calculate this using the following steps:

9/16 + 1/2 = 9/16 + 8/16 = (9 + 8) / 16 = 17/16 = 1 1/16

The correct result would be 1 1/16.

Susie collected data on the favorite type of music of the students of two grades. The table below shows the relative frequencies
svp [43]

Answer:

In Grade 9, 20% of students liked classical music.

Step-by-step explanation:

Your table was hard to decipher, so I have recreated it here.

\begin{array}{c|cccc}&\text{Pop}&\text{Classical}&\text{Heavy Metal}&\text{Total}\\\text{Grade 8}&0.50&0.10&0.40&1.00\\\text{Grade 9}&0.53&0.20&0.27&1.00\\\text{Total}&0.36&0.32&0.32&1.00\\\end{array}

(a) In Grade 9, 53 students liked pop music.

FALSE. 53 % of the students liked pop music. We don't know how many students there were.

(b) In Grade 8, 60% of students liked heavy metal.

FALSE. 40 % of students liked heavy metal.

(c) In Grade 8, 10 students liked classical music.

FALSE. We don't know how many students there were.

(d) In Grade 9, 20% of students liked classical music.

TRUE. 0.20 means 20/100 or 20 %.

Choose the solution(s) of the following system of equations x2 + y2 = 6 x2 – y = 6
ElenaW [278]
<h2>Answer</h2>

x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1

Or as ordered pairs: (\sqrt{6} ,0),(-\sqrt{6} ,0),(\sqrt{5} ,-1),(-\sqrt{5} ,-1)

<h2>Explanation</h2>

Lets solve our system of equations  step by step

x^2+y^2=6 equation (1)

x^2-y=6 equation (2)

1. Solve for x^2 in equation (2)

x^2-y=6

x^2=6+y equation (3)

2. Replace equation (3) in equation (1) and solve for y

x^2+y^2=6

6+y+y^2=6

y^2+y=0

y(y+1)=0

y=0 or y=-1

3. Replace the values of y in equation (3) and solve for x

- For y=0

x^2=6+y

x^2=6

x=\sqrt{6} or x=-\sqrt{6}

- For y=-1

x^2=6+y

x^2=6-1

x^2=5

x=\sqrt{5} or x=-\sqrt{5}

So, the solutions of our system of equation are:

x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1
