Answer:

To find how much money they shared first find the total parts

Which is

5 + 7 + 8 = 20

Deila's share is

5 /20 × £1600

= 1/4 × £1600 = £ 400

Edwin's share is

7/ 20 ×£1600 = £560

Freya's share is

8/20 × £1600

= 2/5 × £1600 = £640

Hope this helps you

Answer:

£ 40,000

Step-by-step explanation:

Given that:

Freya receives 8 parts of the total amount

8 parts = £1600

this means, we can calculate 1 part:

8 parts  = £1600

1 part =£1600/8 = £ 2000

Now, we are able to calculate the total share :

Total number of parts = 8 + 5 + 7 = 20

1 share = £2000

So, 20 shares = £40000

hope this helps,

Good Luck

Jack rabbits are able to reach about 4mph. how fast is this in feet per second? 5,280= 1 mile
gavmur [86]
The speed in feet per second may be calculated by the proper dimensional analysis and the given conversion factors. That is,
             (40 mile / hr) x (5280 feet / 1 mile) x (1 hr / 3600 s) = 58.67 ft / s
Thus, the Jackrabbits' speed may also be expressed as 58.67 ft / s.

1. Jeremy has $12000 cash to invest in the bank compounded at 4% interest annually.
gavmur [86]

Answer:

A(x) = 12000(1.04)^x

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$12000 cash

This means that P = 12000

Compounded at 4% interest annually.

This means that r = 0.04, n = 1

What equation will calculate the value in x years?

A(t) = P(1 + \frac{r}{n})^{nt}

A(x) = P(1 + \frac{r}{n})^{nx}

A(x) = 12000(1 + 0.04)^x

A(x) = 12000(1.04)^x
