Answer:

A = 179.4 km^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+b2) h where b1 and b2 are the lengths of the bases and h is the height

A =1/2 ( 7.6+20) * 13

A = 1/2 (27.6) 13

A = 179.4 km^2

There are 495 coins in a bottle.
Scilla [17]

Answer:

The total value is £268.20.

Step-by-step explanation:

Given : There are 495 coins in a bottle.

1/3 of the coins are £1 coins.

124 of the coins are 50p coins.

The rest of the coins are 20p.

To find : Work out the total value of the 495 coins?

Solution :

According to question,

Total coins = 495

\frac{1}{3} of the coins are £1 coins.

i.e.  The number £1 coins are

\frac{1}{3}\times 495 =165

So, We have £165

124 of the coins are 50p coins.

50p=£0.50

Number of coins were

124\times0.50 =62

So, We have £62 .

Remaining coins were,

495-(124+165)=206

i.e. remaining coins are 206 are of 20p.

20p=£0.20

Number of coins were

206\times0.20 =41.20

So, We have £41.20 .

Now, Adding all of them together,

i.e. £165+£62+£41.20=£268.20

So, The total value is £268.20.
