HCF of 405 and 1605 answer it fast
Rashid [163]

Answer:

hcf=(1,605; 600) = 3 × 5

Step-by-step explanation:

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

1,605 = 3 × 5 × 107;

1,605 is not a prime, is a composite number;

600 = 23 × 3 × 52;

600 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

Multiply all the common prime factors, by the lowest exponents (if any).

gcf, hcf, gcd (1,605; 600) = 3 × 5

gcf, hcf, gcd (1,605; 600) = 3 × 5 = 15;

The numbers have common prime factors.

A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represen
pshichka [43]

Answer:

Step-by-step explanation:

A)

d = r* t         Divide both sides by t

d/t = r

r = d/ t

B)

d = 800000

t = 4 hours

r = 800000 / 4

r = 200000 meters/hour

C

r = 200000 meters / hour * [ 1 km / 1000 meters]

r = 200 km / hr

D

I imagine you are more familiar (especially if you live anywhere but the states) with 200 km/ hour. I am very doubtful that any bird can keep that up for 4 hours. 200 km / hour is equal to about 125 miles / hour. There are few places that will allow a car to travel at that speed. You should be using km/hour because you (should) be more familiar with the units.
