The populations of two towns, town A and town B, are being compared. The population of town A is 4×104 and the population of B is 2×105. How many times greater is the population of town B than town A? The masses of two objects are compared during a physics experiment. It is determined that object A has a mass of 4×10−3 grams and object B has a mass of 4×10−4 grams. How many times larger is the mass of object A than the mass of object B?

1. 5 times

2. 10 times

Step-by-step explanation:

1. Here, we want to know the number of times the population of town B is greater than the population of town A

The simple thing to do here is to divide the population of town B by the population of town A

From the question; population of town B is 2 * 10^5 while the population of town A is 4 * 10^4

So the number of times greater will be;

(2 * 10^5) / (4 * 10^4) = 5

So population of town B is 5 times greater

2. Just like the first question, to know the number of times, we simply divide the mass of object A by the mass of object B

That will be;

(4 * 10^-3) / (4 * 10^-4) = 10 times

So therefore object A is 10 times larger than object B

yes

step-by-step explanation:

give me the question

\

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
