Answer:

-60.X + 32 = 32.r – 60

Because we only have one equation for 2 unknowns.

Step-by-step explanation:

All the equations have solution for r but the one that has 2 unknowns (r and X).

That is because we only have one equation and 2 unknowns.

Then, we only can express one unknown in function of the other and have an indeterminate solution.

Find the area of the circle with the given radius or diameter. Use pi = 3.14. d = 13 A=?

GuDViN [60]

Hello!

The formula for finding area of a circle is: π · r²

Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.

The diameter is 13. 13 ÷ 2 = 6.5

r = 6.5
6.5² = 6.5 × 6.5 = 42.25

π = 3.14

Multiply 3.14 by 42.25 to get the area

3.14 × 42.25 = 132.665

<em>The area of the circle is 132.665 sq. units, which is the last option.</em>

The probability is 1/462.

To find this, we will find the number of combinations of 5 country songs taken 5 at a time, 6 pop songs taken 0 at a time, and the total number of outcomes will be 11 songs taken 5 at a time:

$\frac{_5C_5\times_6C_0}{_{11}C_5}
\\
\\\frac{\frac{5!}{5!0!}\times\frac{6!}{0!6!}}{\frac{11!}{5!6!}}=\frac{1\times1}{\frac{11!}{5!6!}}
\\
\\=\frac{1}{462}$
