Answer: 17.3 ft

Step-by-step explanation:

Perimeter = 2 ( l + w ). So I did 45 divided by 2 which would be 22.5 then subtract that by 5.2 ft which is 17.3. 17.3 + 5.2 = 22.5 x 2 = 45 ft.

5!=5*4*3*2*1;6!=6*5*4*3*2*1 What is the value of 4^4/4!

german

Answer:

$\frac{32}{3}$

Step-by-step explanation:

If 5! is equal to 5 × 4 × 3 × 2 × 1 and 6! is equal to 6 × 5 × 4 × 3 × 2 × 1, then 4! is equal to 4 × 3 × 2 × 1. Thus, 4! = 4 × 3 × 2 × 1, which can simplify to 24. 4! = 24.

$4^{4}$ is basically 4 × 4 × 4 × 4, which can simplify to 256.

So, $\frac{4^{4}}{4!}$ = $\frac{256}{24}$ . $\frac{256}{24}$ can simplify to $\frac{32}{3}$ . Therefore, $\frac{4^{4}}{4!}$ = $\frac{32}{3}$ .

Solve for k <br> 7k+2m = kr + 4m + 3

professor190 [17]

Answer:

$\large\boxed{k=\dfrac{2m+3}{7-r}\ \text{for}\ r\neq7}$

Step-by-step explanation:

$7k+2m=kr+4m+3\qquad\text{subtract}\ 2m\ \text{from both sides}\\\\7k+2m-2m=kr+4m-2m+3\\\\7k=kr+2m+3\qquad\text{subtract}\ kr\ \text{from both sides}\\\\7k-kr=kr-kr+2m+3\\\\7k-kr=2m+3\qquad\text{distribute}\\\\k(7-r)=2m+3\qquad\text{divide both sides by}\ (7-r)\neq0\\\\k=\dfrac{2m+3}{7-r}$

From 86 books to 150 books

Mademuasel [1]

150 books-86 books= 64 books.

We originally have 86 books, so the percent of increase is:
