Answer:
1/2
Step-by-step explanation:
Factor both the numerator and denominator down to prime factors:
500 = 22 * 53
1,000 = 23 * 53
Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest exponents:
gcd (22 * 53; 23 * 53) = 22 * 53
Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):
500/1,000 =
(22 * 53)/(23 * 53) =
((22 * 53) ÷ (22 * 53)) / ((23 * 53) ÷ (22 * 53)) =
1/2
Rewrite result:
1 ÷ 2 = 0.5 as a decimal number.

Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm
Answer:
It is 3 hrs.
Step-by-step explanation:
because the ten dollars of initial fee takes off the 25 dollars, we have 15 left, and mike's bikes charges $5/hour, so 15/3+=5
Real numbers are all rational numbers such as -7 and 4/3 and all irrational numbers. Real numbers are mainly used in counting and also in measurement which is used a lot in real world situations. These numbers help is quantify in the real world.

Answer:
A
Step-by-step explanation:
Let's assume the first pool to have dimensions 3.0 by 2.0
The second pool being 2.1 times the first will have dimensions 6.3 * 4.2
The area of the first pool is 6.0 and that of the second is 26.46
making the area of the second pool 4.41 times that of the first.
