Amani purchased a prepaid phone card for $15. Long distance calls cost 19 cents a minute using this card. Amani used her card on

Iteru [2.4K]

Subtract the balance from the original amount:

15 - 12.34 = 2.66

Now divide the amount spent by price per minute:

2.66 / 0.19 = 14

The call lasted 14 minutes.

Ab= 6cm Ac=12cm <br> Calculate the length of Ad <br> Give your answer to 3 significant figures

Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that $a^2+b^2=c^2$

Therefore, $12^2-6^2=CB^2$

$CB=\sqrt{108}$ (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

$Sin55=CB/CD\\Therefore, CD= 12.686$
