The answer to the question is a
The ratio of red to green is 5:6 which means that for every 5 red cars, there are 6 green cars
The ratio of green to blue is 3:10 telling us that for every 3 green cars, there are 10 blue cars.
The ratio 3:10 is equivalent to 6:20 after we multiply both parts by 2. This now says that for every 6 green cars, there are 20 blue cars.
------------------------------
Let's say we had 5 red cars, 6 green cars and 20 blue cars
Based on that info, we know that the ratio of red to green is 5:6
And the ratio of green to blue is 6:20 which reduces to 3:10
We don't reduce 6:20 to 3:10 however, since that would change the green count from 6 to 3. We want to keep the green count at 6.
So because there are 5 red cars, 6 green cars, and 20 blue cars in this example, and this example points to the proper ratios mentioned earlier, this means that the final answer is 5:6:20. This ratio cannot be reduced or simplified as there are no common factors (other than 1) for 5, 6, and 20.
Answer: 18x^4 - 5x^3 + x^2 - 4
Step-by-step explanation:
We need to add like terms.
-10 and 6 are like terms
-10 + 6 = - 4
-3x^3 and -2^3 are like terms
-3x^3 + -2^3 = -5x^3
There are no other like terms.
18x^4 - 5x^3 + x^2 - 4
Answer:

2)5
3)15
4)28
At first, pg means picogram

A microgram is a unit to measure the mass

Then from both relation

Now we can solve the question
Since the average mass per cell is 67.55 pg
Since the number of cells is 10^5
To find the total mass multiply them

We need to change it to microgram, then multiply it by 10^-6

Put a decimal point at the end of the number and move it 6 places to the left to get the answer
