Answer:

x = 9.9

Step-by-step explanation:

An equilateral triangle is the triangle with equal interior angles.

Each angle has measure of 60°, therefore:

m∠A = 60°

Substitute and solve for x:

7x - 9.1 = 60
7x = 69.1
x = 69.1/7
x = 9.9 (rounded)

The U.S Olympic Team has long distance runners who run a 10,000 meter race. If a runner was to run 50 races, how many centimeter

Ede4ka [16]

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.
