Answer:
54 = 2 × 3³
36 = 2² × 3²
Step-by-step explanation:
The term "factors" can mean different things in this context. Usually, it means "prime factors." Exponents are used to indicate the number of times a factor is repeated. The prime factors of these numbers are ...
54 = 2 × 3³
36 = 2² × 3²
__
Sometimes, we use the word "factors" to mean "positive integer divisors." The number of divisors is the product of the exponents of the prime factors, each increased by 1. That is, 54 has (2·4) = 8 divisors; 36 has (3·3) = 9 divisors. The odd number of divisors is one indication that the number is a perfect square.
The divisors of these numbers are ...
54 is divisible by 1, 2, 3, 6, 9, 18, 27, 54
36 is divisible by 1, 2, 3, 4, 6, 9, 12, 18, 36
Answer:
15840 feet
Step-by-step explanation:
There are 5280 feet in a mile.
5280 * 3 = 15840 feet
Answer:
hmmm I think it's true, if it's not my bad.
The miles that can be travelled in the car on $30 gasoline is 240 miles (option A).
<h3>How many miles can the car travel?</h3>
The first step is to determine the total gallons in the car. The total gallons in the car can be determined by dividing the total value of the gasoline the car by the cost per gallon. Division is the process of determining the quotient of two or more numbers.
Total gallons = total value of gasoline in the car / cost per gallon
$30 / $2.50 = 12 gallons
The next step is to determine the total miles that the car can travel using the gallons available. To determine the total miles, multiply the total gallons by the number of miles that that one gallon can cover.
Total miles = miles one gallon can cover x total gallons in the car
12 x 20 = 240 miles
