The answer is 5:6:20 but can someone explain how plz?
Leya [2.2K]
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.

Helppp!!!<br> Simplify this. Please explain it too.<br><br> 18x^4 – 3x^3 – 2x^3 + x^2 – 10 + 6
strojnjashka [21]

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

A molecular biologist measures the mass of cofactor A in an average yeast cell. The mass is 67.55 pg. What is the total mass in
julia-pushkina [17]

At first, pg means picogram

1pg=10^{-12}g

A microgram is a unit to measure the mass

1\mu g=10^{-6}g

Then from both relation

1pg=10^{-6}\mu g

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

\begin{gathered} T\mathrm{}m=67.55\times10^5 \\ T\mathrm{}m=6755000pg \end{gathered}

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

T\mathrm{}m=6755000\times10^{-6}

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

T\mathrm{}m=6.755\mu g
