The total is 219 miles.

He rides at 38 mph and walks at 4 mph for 8 hours. If he rides for h hours, he walks for 8-h hours.

Set them equal to each other:

219=38h+4(8-h)

Solve and you should get 5.5 hours on the bicycle and 2.5 hours walking.

The fabric cost $181.875

Step-by-step explanation:

Blue fabric bought = 3 3/4 yards , change to improper fraction (4*3)+3/4 = 15/4 yards

Red fabric= 12 5/6 yards = 77/6 yards

Purple fabric= 7 2/3 yards= 23/3 yards

Find total length of fabric bought, 15/4 +77/6 +23/3 =291/12 yards

Cost per yard= $7.50

Total cost will be, 291/12 * 7.50 =$ 181.875

4√6 •√3 how do I show work for this because the answer is 2√12

Yuliya22 [10]

Answer:

$4 \sqrt{6} \times \sqrt{3} = 12 \sqrt{2}$

Step-by-step explanation:

We want to simplify the radical expression:

$4 \sqrt{6} \times \sqrt{3}$

We write √6 as √(2*3).

This implies that:

$4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2 \times 3} \times \sqrt{3}$

We now split the radical for √(2*3) to get:

$4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times \sqrt{3} \times \sqrt{3}$

We obtain a perfect square at the far right.

$4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times (\sqrt{3} )^{2}$

This simplifies to

$4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times 3$

This gives us:

$4 \sqrt{6} \times \sqrt{3} = 4 \times 3 \sqrt{2}$

and finally, we have:

$4 \sqrt{6} \times \sqrt{3} = 12 \sqrt{2}$
