Answer:

For this case we first calculate the area of the complete rectangle.

We have then:

A1 = (8.5) * (11)

A1 = 93.5

Then, we calculate the area of each circle:

A2 = pi * r ^ 2

A2 = (3.14) * (2/2) ^ 2

A2 = 3.14

The total area is given by:

A = A1 - 4 * A2

A = 93.5 - 4 * (3.14)

A = 80.94 in ^ 2

Answer:

A) 80.94

Adding fractions 1/6+2/3=

mars1129 [50]

Answer:

$\frac{5}{6}$

$\frac{1}{6} + \frac{2}{3}$ is equivalent to $\frac{1}{6} + \frac{4}{6}$ .

This is because $\frac{2}{3}=\frac{4}{6}$

The rule is, in order to add fractions, your denominators must be equivalent. In other words, you must have the same denominator for both fractions.

$\frac{1}{6} + \frac{4}{6} =\frac{5}{6}$

This is because 4 + 1 = 5.

Your answer is $\frac{5}{6}$ .

I hope this helps!
