Answer:
20 m/s
Step-by-step explanation:
Distance = rate * time
400 m = rate * 20 seconds
Divide each side by 20 seconds
400m/ 20 seconds = rate
20 m/second = rate
Answer:
1X10^6
or
1.04x10^6
Step-by-step explanation:
You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.
The total amount of bacteria growing in the 20 petri dishes is calculated by multiplying the amount of bacteria in each dish (5.2×10^4) by the number of dishes (20), which gives a result of about 1.04×10^6 bacteria.
Given that there are approximately 5.2×10^4 bacteria in each dish and there are 20 petri dishes, we can find the total amount of bacteria by multiplying these two values together. The calculation is as follows: 5.2×10^4 bacteria/dish * 20 dishes = 1.04×10^6 bacteria. Therefore, there are about 1.04×10^6 bacteria in total growing in the petri dishes.
Answer with explanation:
Commutative property under subtraction:
If a and b are any two real numbers such that,⇒ a-b =b-a, then we say that ,a and b Satisfy Commutative property under Subtraction.
Take any two real numbers
a=5.6
And,b=7
→a-b
=5.6-7
= -1.4
→b-a
=7-5.6
=1.4
So,a-b≠b-a
Therefore , we can say that, real numbers doesn't satisfy commutative property under subtraction.
Option D: ⇒5-1≠1-5
This statement shows that, commutative property doesn't work under subtraction.
