What's the radius of a circle with an area of 64 square feet?

Nady [450]

Area = $\pi r ^{2}$
64 = $\pi r ^{2}$
$\frac{64}{ \pi } =r^2$
$r= \frac{ \sqrt{64} }{ \sqrt{ \pi } } = \frac{8}{ \sqrt{ \pi } }$

If you want the denominator rationalized, the answer is $\frac{8 \sqrt{ \pi } }{ \pi }$

Answer: $x=45$

Simplify both sides of the equation

$x+1.2x+1=100$

$(x+1.2x)+(1)=100$ (Combine Like Terms)

$2.2x+1=100$

Subtract 1 from both sides

$2.2x+1-1=100-1\\2.2x=99$

Divide both sides by 2.2

$2.2x/2.2=99/2.2$

$x=45$

Let x = the number of boxes they need to sell to get to 180
(1 1/8) * x + 75*(1 1/8) = 180 There's a number of ways you could solve this. I think the easiest way (or the easiest to explain) is to start by converting 1 1/8 to a decimal

1/8 = 0.125
1 1/8 = 1 + 0.125
1 1/8 = 1.125 Put this result in the equation.
1.125x + 75 * 1.125 = 180
1.125x + 84.375 = 180 Subtract 84.375 on both sides.
1.125x = 180 - 84.375
1.125x = 96.625 Divide by 1.125
x = 96.625 / 1.125
x = 85

They must sell 85 more boxes to raise 180 dollars.
