Answer:
120 pieces with a bit left over
Step-by-step explanation:
Recall that 1 yard = 36 inches. Thus, a 22-inch piece of ribbon has length
L = (22 inches) / (36 inches / yd) = 11/18 yd.
We must now find out how many 22-inch, or 11/18-yard, pieces can be cut from each 25-yd piece. Divide 25 yd by (11/18 yd/piece), obtaining:
25 yd 18 pieces
--------- * ----------------- = 40.91 pieces.
1 11 yd
Since we're interested in only whole pieces of length 11/18 yd, this produces 40 pieces with 0.91 piece left over.
Cutting up the three 25-yd pieces will then result in 3(40 pieces), or 120, pieces of length 11/18 yd.
Answer:
14 is a positive integer, then it belongs to the set of natural numbers.
1 and 5/9 are rational numbers. The second is already a fraction and the first one, 1, is a natural number, but all the natural numbers can be written as the result of a fraction. For example: 1=6/6.
About the last number, I don't know if it's written correctly. That should be pi maybe, that is 3.14159.... In that case it's an irrational number.
Irrational numbers are all those real numbers that are not rational.
In general you have that:
ℕ ⊂ ℤ ⊂ ℚ ⊂ ℝ
ℕ. Natural numbers. It's the "smallest" one.
ℤ. Integers. Made with positive and negative natural numbers. Includes the natural numbers then.
ℚ. Rational numbers. Everything that can be written as a fraction. Includes both ℕ and ℤ.
ℝ. Real numbers. Any kind of number, fraction or not.
Answer:
24.56 minutes
Step-by-step explanation:
68,700 - (625 * x) = 53,350
We subtract 53,350 from both sides
15,350 - (625 * x) = 0
625x = 15350
x = 15350/625
x = 24.56
He needs to wait 24.56 minutes to get his car.
