The total land area of the world is about fifty-seven million, two hundred eighty thousand square miles is 57, 280, 000 square miles
<em><u>Solution:</u></em>
Given that, we have to write the given words in number
The total land area of the world is about fifty-seven million, two hundred eighty thousand square miles
The number of zeros in million is 6
Here given that 57 million
So, 57 million means 57, followed by 6 digits
two hundred eighty thousand means 280 followed by 3 zeros
two hundred eighty thousand = 280 thousand
Thus the number is: 57, 280, 000
Answer:
Step-by-step explanation:
lets eliminate the parenthesis,
-2x-2=2x-2
-4x=0
x=0
Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
A rational number is any number that can be written as a ratio or a fraction.
So 5/9 is a rational number. So basically that eliminates 2, 3, and 4.
And we are left with 1. as our answer choice which is Rational and real.
Answer:
Only numbers we can think of would be 0 and 1,where cube of the numbers would be equal to the number itself.
Step-by-step explanation:
But in the case of positive numbers the constraints of the question can never be met. So, we'll have to use negative numbers as
(-ve number) ^ (even number) is always a postive number and (-ve number)^(odd number) is always a negative number.
Eg:- (-2)^3= -2 *-2 *-2= -8
(-2)^2= 4
Since, negative sign can never be associated with 0. Eliminate 0 as a possible answer.
Only option left is -1. Lets test if -1 is correct or not.
(-1)^3= -1*-1*-1= -1 i.e the number itself.
(-1)^2=-1*-1=1 which isn't equal to -1.
Therefore, -1 is the solution to this problem.
