A dollar bill is about 15.5 cm long. If seventeen trillion dollar bills were laid end to end around the Earth's equator, how man
Mariana [72]

Answer:

The dollar bills would encircle earth 65753.1 times

Step-by-step explanation:

We have

Length of dollar bill = 15.5 cm

Total dollar bills = 17 trillion = 17\times 10^{12}

Thus the length of 17 trillion dollar bills equals

15.5\times 17\times 10^{12}cm\\\\=263.5\times 10^{12}cm\\\\=\frac{263.5\times 10^{12}}{10^{5}}km\\\\=263.5\times 10^{7}km

Now taking shape of earth as a perfect sphere the circumference of earth becomes

C=2\pi r\\\\=2\times \pi \times 6378km\\\\=40074.1558km

Thus the number of times the dollar bills would encircle earth equals

\frac{263.5\times 10^{7}km}{40074.1558km}=65753.21times

John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches.
Lady_Fox [76]

Answer:

13.5 inches

Step-by-step explanation:

Perimeter of the paper square = 18inches

Perimeter of a square = 4s

4s = 18 inches

s = 18/4 = 4.5 inches

Therefore, each side of the square = 4.5 inches.

When the square is cut into 2 rectangles,

The perimeter of one of the rectangles is 10 inches.

Perimeter of the second rectangle = 2L + 2W

Let the length of the rectangle (L) = one side of the square = 4.5 inches

Width of the Rectangle = Length of the square/2 = 4.5 inches/ 2 = 2.25

Perimeter of the second rectangle = 2(4.5) + 2(2.25)

= 9 + 4.5

= 13.5 inches

In the figure, PQ is parallel to RS. The length of PQ is 2 cm; the length of
Rashid [163]

Answer:

Step-by-step explanation:

Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it. So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/? the ? is 15.

The inside wheels of a car traveling on a circular path are rotating half as fast as the outside wheels. The front two wheels ar
barxatty [35]

Answer:

  about 37.7 feet

Step-by-step explanation:

If the outside wheels are turning twice as fast, they go twice the distance in the same time. The distance they travel is proportional to the radius of the circle, so the outside circle must have twice the radius of the inside circle.

Adding 6 ft to the radius of the inside circle doubles the radius, so the inside circle's radius must be 6 feet. Then the circumference of the inside circle is ...

  C = 2πr = 2π(6 ft) = 12π ft ≈ 37.7 ft
