We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m

A total of 754 tickets were sold for the school play. They were either adult tickets or student tickets. There were 54 more tick
Veseljchak [2.6K]

Answer:

Answer: 350

Step-by-step explanation:

Explanation:

a = adult tickets

s = student tickets

║ a + s = 754

║s = a + 54

Plug s = a + 54 into a + s = 754

a + (a + 54) = 754

a + a + 54 = 754

2a + 54 = 754

2a = 754 - 54

2a = 700

a = 350

The Big Falcon Rocket (BFR or Starship) from Space X can carry approximately 220,000 pounds. If they only carried $100 bills, ho
kifflom [539]

Answer:

$9,979,032,100 or $9.979 billion

Step-by-step explanation:

The approximate weight of a $100 bill is 1 gram.

All of the calculations bellow assume that the volume of the bills would not be an issue and only concerns weight.

1 pound is equivalent to approximately 453.59237 grams.

The weight in grams that the Big Falcon Rocket can carry is:

W= 220,000*453.59237=99,790,321.4\ g

Since each bill weighs 1 gram, the number of bills it could carry, rounded to nearest whole bill is 99,790,321. The total amount it could carry is:

A=99,790,321*\$100=\$9,979,032,100
