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.

Korvikt [17]

Answer:

First we must learn to dissect a question.

<h3>Explanation:</h3>

Part 1

We can list our facts first:

Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

$6.5 \times 1.5 = 9.75 \: teaspoons$

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

$9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp$

A hairdryer transfers 36,000J in one minute, what is the power rating of the hairdryer?

Verdich [7]

Answer:

1. 600 watts

2. 35640 J

3. 55%

4. 20 J

5. The cost of running the fire is 8p.

Step-by-step explanation:

1. Energy = 36 000 J , t = 1 minute = 60 seconds

Power = $\frac{energy}{time}$

= $\frac{36000}{60}$

= 600 watts

2. Power = $\frac{work done}{time}$

⇒ work done = Power × time

= 99 × 360

= 35640 J

3. Efficiency = (Output / Input) × 100

= $\frac{55}{100}$ × 100

= 55%

4. Work done = Force × distance

= 5 × 4

= 20 J

5. Given that 1 KWh cost 2p, Power = 4 KW and time = 4 hours.

Power = $\frac{energy}{time}$

Energy = Power × time

= 4 × 4

= 16 KWh

The cost of running the fire = $\frac{16}{2}$

= 8p
