The amount of money Emma receives in this scenario is £35.

<h3>What is Ratio?</h3>

This is defined as a comparison of numbers that indicates their sizes in relation to each other.

Helen and Emma = 2 : 5

2 = 5

x = x+21

We then cross multiply

5x = 2 ( x+21)

5x = 2x + 42

5x - 2x = 42

3x = 42

x = 42/3 = 14

Emma received x+21

= 14+21 = £35

In how many ways can two integers be selected from 60 consecutive positive integers so that their sum is even?

padilas [110]

Using the combination formula, it is found that the integers can be chosen in 870 ways.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The resulting sum will be even if both numbers are even(2 from a set of 30) or if both numbers are odd(also 2 from a set of 30), hence:

$T = 2C_{30,2} = 2\frac{30!}{2!28!} = 870$

The integers can be chosen in 870 ways.

The sum of two numbers is 36. the first number is 1/5 of the second number. what are the numbers?

Digiron [165]

6 and 30. 6 is 1/5 of thirty. If the first number is x,that means that the second number is 5x. Combine like terms. 6x = 36. 36/6 = 6. x = 6. The first number is 6. the second number is 5x. Replace x with 6. 5 * 6 = 30. 30 is the second number.
