What is 5 1/2 of 60%

EleoNora [17]

You mean 60%of 5 1/2? that makes more sense...

i would do it like this:

$\frac{60}{100}* 5\frac{1}{2}$

(60% is the same as $\frac{60}{100}$

$5\frac{1}{2}=\frac{11}{2}$

(so that there is no confusion, i've put it into an improper fraction

now we can multiply:
$\frac{60}{100}* \frac{11}{2}=$

$\frac{6}{10}* \frac{11}{2}=$

$\frac{3}{5}* \frac{1}{2}=$

$\frac{3*11}{10}=$

$\frac{33}{10}=$

which is 3.3.

so 60% of 5 and a half is 3.3.

- f(x) = 3x3 – 21×² – 54x<br>Zero<br>Multiplicity<br>Effect

xenn [34]

Answer:

x = 9 or x = 0 or x = -2

Step-by-step explanation:

Solve for x:

3 x^3 - 21 x^2 - 54 x = 0

The left hand side factors into a product with four terms:

3 x (x - 9) (x + 2) = 0

Divide both sides by 3:

x (x - 9) (x + 2) = 0

Split into three equations:

x - 9 = 0 or x = 0 or x + 2 = 0

Add 9 to both sides:

x = 9 or x = 0 or x + 2 = 0

Subtract 2 from both sides:

Answer: x = 9 or x = 0 or x = -2

Answer:

see explanation

Step-by-step explanation:

Consider perfect squares on either side of 73, that is

64 < 73 < 81 , then

$\sqrt{64}$ < $\sqrt{73}$ < $\sqrt{81}$ , that is

8 < $\sqrt{73}$ < 9
