Three tables are placed side by side. One table is 6 feet 3 inches wide, another is 3 feet 7 inches wide, and the third is 6 fee

nevsk [136]

Answer:

Total width of tables combined = 16 feet and 4 inches

Step-by-step explanation:

Given:

Width of tables

1) 6 feet 3 inches

2) 3 feet 7 inches

3) 6 feet 6 inches

The tables are combined. We need to find the total width.

Total width of the tables combined = Sum of the widths of the tables

⇒ $6\ ft\ 3\ in+3\ ft\ 7\ in + 6\ ft\ 6\ in$

Adding feet and inches together.

⇒ $(6+3+6)\ ft +(3+7+6)\ in$

⇒ $15\ ft + 16\ in$

[∵ $12\ in = 1\ ft$ , we can split $16\ in = 12\ in + 4\ in$

⇒ $15\ ft + 12\ in+4\ in$

⇒ $15\ ft + 1\ ft+4\ in$

⇒ $16\ ft\ and\ 4\ in$

Total width of tables combined = 16 feet and 4 inches

A random sample of 5200 permanent dwellings on an entire reservation showed that 1571 were traditional hogans.

quester [9]

P^ = 1571/5200 = 0.3021

99% C I = 0.3021 + or - 2.58sqrt((0.3021(1 - 0.3021))/5200) = 0.3021 + or - 0.0064 = 0.296 to 0.309
lower limit = 0.296
upper limit = 0.309

A man is in a boat 2 miles from the nearest point on the coast. He is to go to point Q, located 3 miles down the coast and 1 mil

mafiozo [28]

Answer:

The answer is "0.45385".

Step-by-step explanation:

The time is taken to reach the coast $= \frac{\sqrt{(2^2 + x^2)}}{4}$

The time is taken to reach Q after reaching the coast $= \frac{\sqrt{(1 + (3-x)^2)}}{4}$

Total time, $T= \frac{\sqrt{(1 + (3-x)^2)}}{4}+ \frac{\sqrt{(1 + (3-x)^2)}}{4}$

This has to be minimum,

$\to \frac{dt}{dx} = 0$

$\to \frac{\sqrt{(2^2 + x^2)}}{2} + \frac{\sqrt{1 + (3-x)^2}}{3}\\\\ \frac{x}{4}\sqrt{(4+x^2)} + \frac{(x-3)}{(4\sqrt{(x^2-6x+10)}} = 0\\\\\frac{x^2}{16} \times (4+x^2) = \frac{(x-3)^2}{16 \times (x^2-6x+10)}\\\\x^2(4+x^2) = \frac{(x-3)^2}{(x^2-6x+10)}\\\\4x^2+x^4 = \frac{ x^2+9-6x}{(x^2-6x+10)}\\\\ 4x^2+x^4(x^2-6x+10) = x^2+9-6x\\\\4x^4-24x^3+40x^2+x^6-6x^5+10x^4= x^2+9-6x\\\\x^6-6x^5+ 14x^4-24x^3+39x^2+6x-9=0\\\\$
