Answer:

3 formas

Step-by-step explanation:

Se nos pide que averigüemos cuántas formas puede utilizar para cruzar un río si tiene 1 bote y 2 barcos

Número total de barcos = 3 barcos.

Resolvemos esto usando la regla de combinación.

C (n, r) = nCr = n! / R! (n - r)!

n = Número de barcos = 3

r = Número de ríos = 1

3C1 = 3! / 1! (3 - 1)!

= 3! / 1! × 2!

= 3 × 2 × 1/1 × 2 × 1

= 3 formas.

Por lo tanto, el número de vías por las que puede cruzar un río utilizando 1 bote y 2 barcos es de 3 formas.

Firdavs [7]

Answer: 180 cookies


Step-by-step explanation: If 1.75 cups of flour is required to make a batch and the bakery used 5.25, the bakery made 3 batches, since 1.75(3) is 5.25. One dozen is 12 cookies, and there are 5 dozen cookies in each batch. If there are 3 batches, then there are 15 dozens of cookies. 15(12) is 180.

What are the steps of factoring (5m-2)^2-(3m-4)^2 ?
Svetlanka [38]
We use the formula a^2 - b^2 = ( a - b )( a + b );
We have a = 5m - 2 and b = 3m - 4;
<span>(5m-2)^2-(3m-4)^2 = (5m - 2 -3m + 4) x (5m-2 + 3m - 4) = (2m + 2)(8m - 6) = 2(m +1) x 2(4m - 3) = 4(m+1)(4m-3);

lakkis [162]

The prime factors that the numbers 24 and 36 have in common are found out to be; 2 × 2 × 3

<h3>How to get prime factors? </h3>

A prime factor of a number is simply factor of that number that is a prime number. This means that any of the prime numbers that can be multiplied to give the original number.

Now, we have;

Prime factors of 36; 2 × 2 × 3 × 3

Prime factors of 24; 2 × 2 × 2 × 3

The prime factors that they have in common will be; 2 × 2 × 3
