Answer:

  d.  5.454 x 10^7 square kilometers

Step-by-step explanation:

Adding 4.46×10^7 to 0.994×10^7 we get 5.454×10^7.

___

Before you can add numbers in scientific notation, they must both have the same multiplier. Here, we can see that the area of Asia will be written with an exponent of 7, so we choose to write both numbers that way.

  44,600,000 = 4.4×10,000,000 = 4.4×10^7

  9.94×10^6 = (0.994×10)×10^6 = 0.994×10^7

The sum is (4.400 +0.994)×10^7 = 5.454×10^7.

Combined area is 5.454 × 10^7 km²

Step-by-step explanation:

• Step 1: Find the combined area of Asia and Europe.

Area of Asia = 44,600,000 km²

Area of Europe = 9,943,106 km²

⇒ Combined Area = 44,600,000 + 9,943,106

                               = 54,543,106 km²

• Step 2: Convert to one significant figure.

54,543,106 = 5.454 × 10^7 km² (Dividing and multiplying by 10^7)

Answer:

Step-by-step explanation:

If she sells 8 dozen, she will get exactly 120 dollars. But that is not what the question says.

Sales = 8 * 15 = 120

The question says that she wants to make more than 120 dollars. Therefore the circle must be an open one. B is the proper answer. A is close but A means that she is willing to stop her sales when they reach 120 dollars. Not so.

A is not the answer.

You can find out which is the better deal by dividing the price by the amount of ounces available. Here are the unit prices for each answer choice: A (.15), B(.16), C(.12), and D(.15). The cheapest unit price would be the best deal. Thus, the answer is choice C! Hope this helped :))
