Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains 
Number of cars in each train = 
= 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car Number of cars = 16 14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224 10 = <em>2240</em>
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>
How many roots has the given polynomial?</h3>
We have the polynomial:
To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.

By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L
<h3>What is relation between ml and litre?</h3>
Relation between ml and litre is that 1 litre =1000 ml
we know that litre and ml are two units of volume and we can convert data from one to another using their relation
Now here given data is in ml
and data is 0.71 ml
We can convert 0.71 ml in litre as
71ml = 0.71/1000 litre
71ml= 0.00071 litre =0.00071 L
By using relation between ml and litre we got that 0.71 ml is equal to 0.00071 L
