Solve for c: c=5 5/6 x 2

Marina86 [1]

Hi there!

c=11 2/3

1.Convert 5 5/6 into mixed number:

$5 \frac{5}{6}=\frac{35}{6}$

2.Convert 2 into fraction term:

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

3.Convert both fraction into same denominator:

$\frac{35}{6}=\frac{35}{6}$

$\frac{2}{1}=\frac{12}{6}$

4.Multiply the two terms:

$\frac{35}{6}$ · $\frac{12}{6}=\frac{70}{6}$

5.Simplfly the fraction term:

$\frac{70}{6}=\frac{35}{3}$

$\frac{35}{3}=11 \frac{2}{3}$

Therefore, c=11 2/3.

What are the values of a and b

makvit [3.9K]

Answer:

$\large\boxed{B.\ a=8,\ b=4\sqrt5}$

Step-by-step explanation:

We have three similar triangles:

$\triangle ABC\sim\triangle DBA\sim\triangle DAC$

therefore the sides are in proportion:

$\dfrac{AD}{CD}=\dfrac{BD}{AD}$

We have AD = a, CD = 16 and BD = 4. Substitute:

$\dfrac{a}{16}=\dfrac{4}{a}$ cross multiply

$(a)(a)=(16)(4)\\\\a^2=64\to a=\sqrt{64}\\\\a=8$

and other proportion:

$\dfrac{AB}{BC}=\dfrac{BD}{AB}$

We have AB = b, BC = 16 + 4 = 20 and BD = 4. Substitute:

$\dfrac{b}{20}=\dfrac{4}{b}$ cross multiply

$(b)(b)=(20)(4)\\\\b^2=80\to b=\sqrt{80}\\\\b=\sqrt{16\cdot5}\\\\b=\sqrt{16}\cdot\sqrt{5}\\\\b=4\sqrt{5}$
