Are there any other numbers to this question? I will be glad to help.
Step-by-step explanation:
A. When dealing with large numbers, sometimes it's easier to write them in a form of exponents of number ten. The value of the exponent shows how many times we multiply 10 by itself. That means that 10^3 is 10•10•10 or that 10^6 is 10•10•10•10•10•10.
So, when finding how many times on number is greater then the other, we need to divide them. We divide 8x10^6 by 2x10^5. It is done by dividing the numbers and subtracting the exponents; 8/2=4 and 10^6/10^5 is 10^6-5=10^1. So the correct answer is 4x10^1 which is 4x10, and that is 40.
B. Now, we have a total number of coins (2.25x10^5), and diametar of a coin (19mm = 19x10^-6km). Our task is to calculate the distance across which the coiks laid side-by-side would expand. We can find this by multiplying the number of coins with a diametar of single penny, 2.25x10^5•19x10^-6. Multiplying is done by multiplying the numbers (2.25x19=42.75) and adding the exponents (5+(-6)=5-6=-1). So, the distance is 42.75x10^-1km, which equals to 4.275 km. Obviously, this is less then the stated 5 km given in the text, so the reportet's statement is false.
4 or less: 4/8 so 1/2
6 or less: 6/8 so 3/4
8 or less: 8/8 so 1
Answer:
D x is all real numbers
R y ≥ -3
Step-by-step explanation:
The domain is the values that x can take
The domain is all real numbers
The range is the values that y can take
The range is y is greater than or equal to -3
Rates are used to measure a quantity over another.
<em>The 1.8 million cars use </em>
<em> liters each year</em>
Given
--- distance
First, we calculate the number (n) of gallons used by each car
Solve for n
So, we have:
Convert miles to kilometers
The number of gallons (N), used by all the cars is:
Convert to liters
In scientific notation to 2 decimal places, we have:
<em>Hence, the number of liters used is </em><em />
