United States <strong>and</strong> Canada is approximately<br />

Thus: A ​__<br />

What is the area of trapezoid QRST?<br />

E. 2,500,000,000 km<br />

A. 2 sq cm<br />

In Example 8, start by converting 2.5 10 6 from<br />

B. 18 sq cm<br />

scientific notation to st<strong>and</strong>ard form:<br />

C. 24 sq cm<br />

D. 72 sq cm<br />

2.5 10 6 2,500,000 meters<br />

E. 360 sq cm<br />

To change from meters to kilometers, divide by 1,000:<br />

2,500,000 1,000 2,500 km<br />

In Example 6, use the formula for the area of a<br />

trapezoid:<br />

Area __ ​ 1 2 ​ • height • (sum of the bases)<br />

Example 9<br />

From the figure, we know that the height of QRST If the mean of 6, 8, 10, <strong>and</strong> x is 8, what is x?<br />

is 4 cm <strong>and</strong> that one base is 6 cm, while the other<br />

base is 3 cm.<br />

Example 7<br />

K. 32<br />

Kendra traveled on a train for 8 hours<br />

<strong>and</strong> 12 minutes at an average speed of<br />

110 kilometers per hour. How far did she travel?<br />

F. 120 km<br />

G. 170 km<br />

H. 891 km<br />

J. 892 km<br />

K. 902 km<br />

In Example 9, set up an equation to calculate the<br />

mean <strong>and</strong> solve for x:<br />

​ _______________<br />

6 8 10 x ​ 8<br />

4<br />

24 x 32<br />

x 8<br />

In Example 7, first convert 12 minutes into a<br />

fraction of an hour <strong>and</strong> add that to the 8 hours:<br />

___ ​ 12<br />

60 ​ ​1 __ ​hour 8 hours<br />

5<br />

So Kendra’s total travel time was 8 __ ​ 1 ​hours. Multiply<br />

5<br />

her travel time by 110 kilometers per hour to<br />

calculate the distance she traveled:<br />

8 __ ​ 1 5 ​ • 110 ___ ​ 41<br />

5 ​ • 110 902 km<br />

Taking the Sample Tests<br />

Now you are ready to try sample test Form A. Begin<br />

by carefully reading the Directions on pages 28 <strong>and</strong><br />

29 <strong>and</strong> filling out side 1 of the Answer Sheet on page<br />

30. For Form A, use side 2 of the Answer Sheet (page<br />

31). When you are ready for Form B, use the Answer<br />

Sheet on page 69. You may tear out pages 31 <strong>and</strong> 69<br />

to make it easier to mark your answers.<br />
