Answer: The musical group sold  60%of the white hats and  70%of the black hats.

A greater percentage of  black hats were sold.

Step-by-step explanation:

Hi, to answer this question we have to divide the number of hats sold by the number of total hats for each case.

Then, we have to multiply that result by 100, to obtain the result in percentage form.

Mathematically speaking:

  • <em>White Hats: (120/200) x 100 =</em><em>60% </em>
  • <em>Black hats: (210/300) x 100= </em><em>70% </em>

The musical group sold 60%of the white hats and 70%of the black hats.  

A greater percentage of black hats were sold. (Since 70 > 60 )

Feel free to ask for more if needed or if you did not understand something.

PolarNik [594]

Answer:

Width = 40 meters

Length = 167 meters

Step-by-step explanation:

Let

Width of the pool = x meters

Then

Length of the pool = 4x + 7 meters

and

Perimeter =2(x+4x+7)=2(5x+7)=10x+14 meters

Hence,

10x+14=414\\ \\10x=414-14\\ \\10x=400\\ \\x=40\ meters\\ \\4x+7=4\cdot 40+7=167\ meters

PLEASE HELP ME!!!<br> Find the vertex of f(x)=x^2+2x+3 and show your work
belka [17]

Answer:

The vertex is the point (-1,2)

Step-by-step explanation:

we have

f(x)=x^{2}+2x+3

Convert into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)-3=x^{2}+2x

Complete the square. Remember to balance the equation by adding the same constants to each side.

f(x)-3+1=x^{2}+2x+1

f(x)-2=x^{2}+2x+1

Rewrite as perfect squares

f(x)-2=(x+1)^{2}

f(x)=(x+1)^{2}+2 ----> equation in vertex form

The vertex is the point (-1,2)

motikmotik
The constant of proportionality stays the same no matter what values the variables take, so in our example independently of the cost of the item (and of the tax value, which is dependent on the cost value).

Here the only value that does not change is the 0.007, the rate! - this is the correct answer.
