How do you solve: 21 11/12 plus 17 5/12

GarryVolchara [31]

The problem is $21 \frac{11}{12} + 17 \frac{5}{12}$

Add the whole numbers

$21 + 17 = 38$

Match up the fractions and make sure the denominators are the same (they are)

$\frac{11}{12} + \frac{5}{12}$ $= \frac{16}{12}$

Break down the fraction

$16$ ÷ $12 = 1 \frac{4}{12}$

Reduce-You need to find a common factor for both the numerator and denominator

$4$ ÷ $4$ $= 1$

$12$ ÷ $4 = 3$

Combine everything

$38 + 1\frac{1}{3} =39 \frac{1}{3}$

Answer: $39 \frac{1}{3}$

4. The area of a regular hexagon is 50 in. Find the length of a side. Round your answer to the nearest tenth.

Vikki [24]

Answer: 4.4

Step-by-step explanation:

The formula for calculating the area of regular hexagon is given as :

Area = $\frac{3\sqrt{3}}{2}$ $a^{2}$

Where a is the length of a side.

Substituting the value given , we have :

50 = $\frac{3\sqrt{3}}{2}$ $a^{2}$

50 x 2 = $3\sqrt{3}$ $a^{2}$

100 = $3\sqrt{3}$ $a^{2}$

Divide through by $3\sqrt{3}$

$a^{2}$ = $\frac{100}{3\sqrt{3}}$

$a^{2}$ = 19.24500897

Take the square root of both sides :

a = $\sqrt{19.24500897}$

a = 4.3869

To the nearest tenth

a = 4.4
