Gordon and Malachy win some money and share it in the ratio 6:1. Gordon gets £25 more than Malachy. How much did they get altogether?

Answers

Answer:

£ 35

Step-by-step explanation:

Ratio = 6 : 1

Gordon's share = 6x

Malachy's share = x

6x - x = 25

5x = 25

x = 25/5

x = 5

Gordon's share = 6x = 6*5 = 30

Malachy's share = x = 5

Total money they get = 30 + 5 = £35

Esther and Jim plan to add a pond to their property. The area of the pond is 44 square meters. what is the radius

Answers

We are asked to find the radius of the pond given the total area of the pond. Since the radius is asked, we can assume that the pond is in the share of a circle. The equation to find the area of a circle is A = $\pi r x^(2)$ . We are already given with the area so the radius of the pond is 3.74m.
