A...area = 379.94 in^2

π=3.14

r...radius

d...diameter= 2r

A= π*r^2

r^2=A/π

r=√(A/π) = 11 in

d=2r =22 in

If 445 to base n is equal to 173,find the value of n

Troyanec [42]

Answer:

6

(4×n²) + (4×n¹) + (5×n^0) = 173

4n² + 4n + 5 = 173

4n² + 4n = 168

divide through by 4

n² + n - 42 = 0

n² + 7n - 6n - 42= 0

(n + 7)(n - 6) = 0

n = -7 or 6

but the solution is 6 since base is not negative.

What is the width of a rug that is 36 1/4 square feet and 8 3/4 wide

blondinia [14]

Answer: $4\frac{1}{7} ft$

<u>Step-by-step explanation:</u>

Area (A): $36\frac{1}{4} = \frac{4(36)+1}{4} = \frac{144+1}{4} = \frac{145}{4}$

Length (L): $8\frac{3}{4} = \frac{4(8)+3}{4} = \frac{32+3}{4} = \frac{35}{4}$

width (w): W

A = L x W

$\frac{145}{4}$ = $\frac{35}{4}$ x W

$(\frac{4}{35})$ $\frac{145}{4}$ = $(\frac{4}{35})$ $\frac{35}{4}$ x W

$\frac{4(145)}{35(4)} = \frac{145}{35} = \frac{5(29)}{5(7)} = \frac{29}{7} = W$

$\frac{29}{7} = \frac{7(4) + 1}{7} = 4\frac{1}{7}$
