There are 100 centimeters in 1 meter. So to start with you must multiply 10000 by 100 to determine the number of centimeters in each race. This answer will be 1000000. Then to determine the number of centimeters in fifty races, you must multiply 1000000 by 50. This answer is 50000000. Then you must put it in scientific notation. 

To do this you must move the decimal place over to the left until there is only one, nonzero number in front of it. Because you will move it to the left, your exponent will be positive. Therefore, your answer will be B.

The measures of the angles of XYZ are in the ratio 1:4:10. What are the measures of the angles?
Elanso [62]

Answer:the angles are 12 degrees, 48 degrees and 120 degrees.

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees.

The measures of the angles of XYZ are in the ratio 1:4:10. The total ratio is the sum of the proportion of each angle. It becomes

1 + 4 + 10 = 15

Therefore, the measure of the first angle would be

1/15 × 180 = 12 degrees

Therefore, the measure of the second angle would be

4/15 × 180 = 48 degrees

Therefore, the measure of the third angle would be

10/15 × 180 = 120 degrees
