Is the square root of infinity still infinity?.
hram777 [196]
The square root of infinity is still infinity, or rather, undefined or indeterminate. For example, if you take the square root of a big number, you will still have a big number as a result, now if you make the number even bigger, the square root will also get bigger, now imagine what will happen if this number is infinite.

Solve, using the correct order of<br> operations, when x = 7 and y = 3<br> (x – 3) + 2y
sweet [91]

Answer:

10

Step-by-step explanation:

<em>Since it given that:</em>

<em>x = 7 and y = 3</em>

<em>We can substitute x and y:</em>

<em>(7-3) + 2(3)</em>

<em>7 - 3 = 4</em>

<em>4 + 2(3)</em>

<em>2(3) = 6</em>

<em>4 + 6 =10</em>

<em>Thus the answer is 10.</em>

Please answer also if you answer this one please answer my other one it basically the same
lianna [129]

Answer:

D is the correct answer.

Step-by-step explanation:

<em>Step 1: Write the data</em>

Total number of songs = 100

Total ratio = 1

Total percentage = 100%

Ratio of jazz songs = 1/4

Percentage of jazz songs = 1/4 x 100 = 25%

Ratio of pop songs = 1 - 1/4 = 3/4

Percentage of pop songs = 3/4 x 100 = 75%

<em>Step 2: Match the statement.</em>

The correct statement is D; 25% are Julian's songs are jazz because 1/4 = 25/100 and 75% are pop because 3/4 = 75/100.
