Answer:
7 minutes
Step-by-step explanation:
When Jay and Kevin work together to clear the driveway of snow it takes an average of 14 minutes. If Jay or Kevin works alone to clear the driveway he can clean it in 21 minutes. In total if Jay works alone then he can clean the driveway by spending additional 7 minutes.
For this case we have:
, we must run the decimal point 20 spaces to the left.
, we must run the decimal point 12 spaces to the left.
Thus, it is observed that the mass of a small virus is smaller!
We subtract and obtain:
ANswer:
The mass of a small virus is less!
Answer:
<h2>$39,000</h2>
Step-by-step explanation:
Look at the picture.
To find the Median, place the numbers in value order and find the middle number (right picture).
Median = $39,000
A is located at (-3,-5) B is located at (1,-9)
-3 + 1 = -2/2 =-1
-5 + -9 = -14/2 = -7
midpoint is (-1,-7)
1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
