John

You went to the store to buy a gift for your friend. Jeans are 20 dollars (what a deal) so you buy one for yourself and your friend. Then you see this really cute top and you want to match with your friend, so you get two of those too.

The total on the bill is $110.

While walking to your car, you lose the receipt.


When you give your friend the gift, she is excited. But says you spent too much money on her! She wants to pay you back for the shirt, but you can't remember how much it cost

What is the length of AB? (Nearest TENTH) A.34 B.105.3 C.11.8 D.24.7
jasenka [17]

Answer:

The answer is option A.

Step-by-step explanation:

To find the length of AB we use sine

sin∅ = opposite / hypotenuse

From the question

AB is the hypotenuse

AC is the opposite

sin 36 = AC / AB

sin 36 = 20/ AB

AB = 20 / sin 36

AB = 34.026

<h3>AB is 34 to the nearest tenth</h3>

Hope this helps you

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers (k) she can drive with 12 li
masya89 [10]

Answer:

132 kilometers

Step-by-step explanation:

Given: Pamela drove her car 99 kilometers and used 9 liters of fuel.

To find: Number of kilometers Pamela drove in 12 liters of fuel.

Solution:

It is given that Pamela drove her car 99 kilometers and used 9 liters of fuel. Also the relationship between kilometers and fuel is proportional.

So, let us assume that she can travel x kilometers in 12 liters of fuel.

By proportionality we have,

99:9 :: x:12

\frac{99}{9} =\frac{x}{12}

11=\frac{x}{12}

x=12\times11

x=132

Hence, she can travel 132 kilometers in 12 liters of petrol.
