Eli,Freda and geoff where given £800 to share in the ratio of there ages

Ilia_Sergeevich [38]

Answer 180, 260 and 360

Step-by-step explanation

Eli age = 9

Freda age = 13

Geoff age = 18

We write the ages in ratio as 9 : 13 : 18

Now sum all the ages 9 + 13 + 18 = 40

The total amount to be shared is £800

Therefore Eli share = 9/40 x £800 = £180

Freda share = 13/40 x £800 = £260

Geoff share = 18/40 x £800 = £360

Shtirlitz [24]

Answer:

$area = 2.54 {ft}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$area \: of \: circle \: = \pi {r}^{2}$

Let pi be (3.14), the radios as given in the question is (0.9). Therefore;

$\pi {r}^{2} = \\ (3.14) \: {(0.9)}^{2} \\ 3.14 \times 0.81 = \\ 2.5434 \: or \: 2.54 {ft}^{2}$

Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredt

Georgia [21]

Find how much it grew:

53 - 20 = 33 inches.

Divide the amount it grew by the original length

33/20 = 1.65

Subtract 1:

1.65 - 1 = 0.65

Multiply by 100 for percent:

0.65 x 100 = 65%

The percent increase is 65%
