In order to answer this problem, you need to remember the place – value chart since you don't want to convert the number to its standard form. The number "fifty million" has nine places. Enumerating from the left would be:
<span>- Ones - Tens - Hundreds - Thousands - Tens thousands - Hundreds thousands - Millions - T<span>ens millions</span></span>
The correct next step that Cynthia should do is to:
D. use the arc markings to determine the radius to
construct the circle
<span>The arc markings are actually used as the baseline in
determining the center and the radius of the circle. The arc markings are
created with the use of a compass. All other choices are completely irrelevant
because what we need is the arc and not the angles. The angles do not create
the circle. Letter C is also wrong because what we are trying to form is the
circle and not the triangle. The triangle is already created.</span>
This is your answer and for the multiplication I gave it to you step by step
<u>Complete Question:</u>
Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?
A. The distance traveled depends on the number of hours traveled.
B. The number of hours traveled depends on the speed of the train.
C. The speed of the train depends on the distance traveled.
D. The speed of the train depends on the number of hours traveled.
<u>Answer:</u>
Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. The distance traveled depends on the number of hours traveled
<u>Step-by-step explanation:</u>
As we know the velocity can de defined as the rate of change of position of objects in a particular time. The formula is given by,

Here, in the question, rate of speed of train is given as 45 miles per hour. if we keep the velocity as constant one, then distance is directly proportionate to the travelled time

If 'v' is constant,

By this we can conclude that, the distance travelled by the train depends on the time taken to travel to it. Hence option A would be the correct one.
