Cheryl and rodney are mixing yellow and blue paint to make green paint. The table shows how much of each color they use. Whose g
Tomtit [17]

The amount of blue color in the green paint is an illustration of ratios and proportions.

Cheryl's green paint has more blue color

The proportion of blue color is calculated as:

\mathbf{Proportion = \frac{Blue}{Blue+ Yellow}}

So, we have:

\mathbf{Cheryl= \frac{16}{16+ 24}}

\mathbf{Cheryl= \frac{16}{40}}

\mathbf{Cheryl= 0.40}

Express as percentage

\mathbf{Cheryl= 40\%}

\mathbf{Rodney= \frac{6}{6+ 10}}

\mathbf{Rodney= \frac{6}{16}}

\mathbf{Rodney= 0.375}

Express as percentage

\mathbf{Rodney= 37.5\%}

By comparison: 40% >37.5%

Hence, Cheryl's green paint has more blue color

What is the product 3x5(2x2+4x+1)
lesya692 [45]

Answer:

6x^7+12x^6+3x^5

Step-by-step explanation:

The given expression is:

3x^5(2x^2+4x+1)

We expand the parenthesis using the distributive property to obtain;

3x^5(2x^2)+3x^5(4x)+3x^5(1)

Recall that;

a^m\imes a^n=a^{m+n}

We apply this property and multiply out the constant terms to obtain;

6x^7+12x^6+3x^5
