Answer:

30.1%

Line the numbers on the right and do not a line the decimal points

      26.2

×  16.43

Second Step:

Multiply the numbers starting on the right, just like multiplying a whole number and ignore the decimals.

       26.2

<span> ×  16.43</span>

         786

     1048

   1572

<span>+ 262   </span>

   430466

A moving sidewalk in an airport moves people between gates. It takes Jason's 8-year-old
likoan [24]

Answer:

The sidewalk moves at 0.5 ft/sec

Josie's speed walking on a non-moving ground is 3.5ft/sec

Step-by-step explanation:

Let x represent the speed of the side walk and y represent her walking speed

It takes Jason's 8-year-old daughter Josie 44 sec to travel 176 ft walking with the sidewalk

Distance = speed × time

176 = (x+y)×44

44x+44y = 176

x+y = 4 .......1

It takes her 7 sec to walk 21 ft against the moving sidewalk in the opposite direction).

21 = (y-x)7

7y - 7x = 21

y - x = 3 ......2

Add equation 1 to 2

2y = 7

y = 3.5 ft/sec

From equation 1

x + y = 4

x = 4 - 3.5 = 0.5

x = 0.5 ft/sec

The sidewalk moves at 0.5 ft/sec

Josie's speed walking on a non-moving ground is 3.5ft/sec
