Chris and Dave and Ed share £720 between them. Chris receives £90 more than Dave. The ratio of Chris's share to Dave's share is

jolli1 [7]

Answer:

Ratio of Ed's share : Dave's share = 4 : 5

Step-by-step explanation:

Total amount shared = £720

Let us assume that Dave receives = £m

So, Chris's share = £90 + m

Also, Chris's share : Dave's Share = 7: 5

⇒ $\frac{90 + m}{m} = \frac{7}{5}$

Here, solving for m , we get : 5(90 + m) = 7m

or, 450 + 5m = 7m

⇒ 2m = 450, ⇒ m = 225

So, Dave's Share = m = £225

Chris's share = £90 + m = 225 + 90 = £ 315

Hence, Ed's share = Total - ( sum of Dave's and Chris's share)

= 720 -( 315 + 225) = £180

So, ratio of Ed's share : Dave's share = £180 : £225

or, Ratio of Ed's share : Dave's share = 4: 5

Area of triangle = 1/2 x base x height

so old triangle we have 1/2 x b x h = 48

new triangle has base 3 times as long and height is half as long
so we would get:

1/2 x (3B) x (1/2H) = area

rewrite as 1/2 x 3/2 x b x H = area

divide by original are os 1/2 x b x h and you end up with 3/2

so new area = 3/2 x old area

new area = 3/2 * 48 = 72 square inches
