Answer:

The best estimate for the number of hours the family drove is 28.8 Hours.

Step-by-step explanation:

The distance Jarrod's family drove is 1778 miles and their average speed was 61.7 miles/hour, and we need the best estimate for the number of hours the family drove. For this we use the distance formula

D=vt

and use solve for t:

t=\frac{D}{v} =\frac{1778\:miles}{61.7\:miles/hr} = \boxed{28.8\:hours.}

Thus the best estimate for the hours driven is 28.8 hours.

<em>It is only an estimate because the speed given is the average speed.</em>

A Pythagorean triple is a triple of natural numbers satisfying the equation a^2+b^2+c^2.
Softa [21]
X, x+2 - two consecutive odd or even numbers
Add the reciprocals of these numbers.
\frac{1}{x}+\frac{1}{x+2}=\frac{x+2}{x(x+2)}+\frac{x}{x(x+2)}=\frac{x+2+x}{x^2+2x}=\frac{2x+2}{x^2+2x}&#10;

Now add the squares of the numerator and denominator, as in the example.
(2x+2)^2+(x^2+2x)^2= \\ 4x^2+8x+4+x^4+4x^3+4x^2= \\ x^4+4x^3+8x^2+8x+4

So this number has to be a perfect square.
x^4+4x^3+8x^2+8x+4= \\&#10;x^4+2x^3+2x^2+2x^3+4x^2+4x+2x^2+4x+4= \\&#10;x^2(x^2+2x+2)+2x(x^2+2x+2)+2(x^2+2x+2)= \\&#10;(x^2+2x+2)(x^2+2x+2)= \\&#10;(x^2+2x+2)^2
It is a perfect square, so this method always works.

The numbers 2x+2, \ x^2+2x, \ (x^2+2x+2)^2 are a Pythagorean triple for any x \in \mathbb{N^+}.

Multiply. Write the answer in lowest terms. <br> 5/7 x 11/7 x 5/6
marusya05 [52]
Hi

5/7 × 11/7 × 5/6 = 55/49 × 5/6 = 275/294

5/7 × 11/7 = (5×11)/(7×7) = 55/49
55/49 × 5/6 = (55×5)/(49×6) = 275/294 (irreducible)

Answer: 275/294
