Answer:

n=\frac{55}{8}

Step-by-step explanation:

First, cross multiply

\frac{11}{n} =\frac{8}{5}

(11)*(5)=8*n

55=8n

Now, flip the equation

8n=55

Divide both sides by 8

\frac{8n}{8} =\frac{55}{8}

n=\frac{55}{8}

hope this helps :)

Rufina [12.5K]

Answer:

4 \times  {3}^{n + 3}

Step-by-step explanation:

\frac{ {18}^{n + 1}  \times {3}^{1 - n}}{  {2}^{n - 1}  }

\frac{ {3}^{2n + 2}  \times  {2}^{n + 1}  \times  {3}^{1 - n} }{ {2}^{n - 1} }

{3}^{2n + 2}  \times  {2}^{2}  \times  {3}^{1 - n}

{3}^{2n + 2}  \times 4 \times  {3}^{1 - n}

= 4 \times  {3}^{n + 3}

Using the approximation 3.14 for \pi what is the radius of a circle with circumference 44m
Feliz [49]

Answer:

7 m

Step-by-step explanation:

Circumference of a circle uses the formula;

Circumference = 2 × pi × radius(r)

If the circumference = 44

then we use the formula above to calculate the value of the radius,

44 = 2 × pi × r...then divide both sides by (2 × pi(3.14))

Radius = 44 ÷ ( 3.14 × 2)

;Radius = 7.01

;Radius = 7m
