Answer:

33%

Step-by-step explanation:

The area of the entire circle:

The radius is 4+3+3 = 10

Area of a circle= pi * r^2


Area of largest circle      = pi * 10^2 = 100 pi


Area of blue ring = Area of blue circle - area of inner white circle

The blue circle has a radius of (4+3) = 7

The inner white circle had a radius of 4

Substituting what we know

Area of blue ring = Area of blue circle - area of inner white circle

                               = pi * r^2 - pi*r^2

                               = pi * 7^2 - pi *4^2

                                = 49pi - 16pi

                                = 33 pi


The percentage of the logo that is blue is the blue ring/ area of largest circle

percentage = 33 pi/100 pi

Canceling pi

percentage = 33/100

                    = 33 %

Consider the relation y = 4|x + 2| + 7. What are the coordinates of the vertex?
aev [14]
To answer, we set the expression inside the absolute value symbol (II) equal to 0. That is,
                           x + 2 = 0
Then, we solve for the value of x.
                           x + 2 - 2 = 0 - 2
Hence, the value of x from the equation above is equal to -2.

Then, substitute the value of x to the equation and drop the absolute value symbol.
                       y = 4(x + 2) + 7
Substituting,
                       y = 4(-2 + 2) + 7
                             y  = 4(0) + 7
                                 y = 7

Thus, the vertex of the absolute value equation is equal to (-2,7). The answer is the last choice.

lesya [120]

Answer:

6.2 kilograms/ deciliters

Step-by-step explanation:

megagrams to kilograms

1 megagram = 1000 kilograms

hectoliter to deciliter

1 hectoliter = 1000 deciliter

Using conversion factors

6.2megagrams      1000 kilgrams         1 hectoliter

---------------------- * ----------------------- * -------------------------

hectoliter                  1 megagram       1000 deciliters
