Answer:

If i did the math correctly the answer to number 9 is a.5 and number 10 is c. Vanilla and German chocolate cupcakes represent about 21% of total sales

Step-by-step explanation:

for number 9 you write down each of the numbers with a dot above them. how many dots represents how many times you repeat the number. you then add it together and divide by the amount of numbers you added together. so in this case it would be 65 ÷ 12. this ends up being 5.41 but you'd round down to 5.

for number 10 you write out how many each flavor sold. then you put those numbers over the total cupcakes sold. divide the denominator by 100 and then divide the numerator by that number. then that gives you the fractions of the percent each one was. the german chocolate and the vanilla added together is almost exactly 21% of the sales

The formula of an area of a circle:

A_O=\pi r^2

We have

r = 1.8 m

π ≈ 3.14

Substitute:

A_O=\pi\cdot1.8^2=3.24\pi\ m^2\approx3.24\cdot3.14=10.1736\ m^2\approx10.17\ m^2

algol [13]

Answer:

B. W,V,Z

Step-by-step explanation:

Collinear points are two more points in the same plane that lie in a straight line.

From the diagram, Z is the intersection of the two diagonals of quadrilateral VXWY.

The points V, Z and W lie along the same diagonal, hence they are collinear.

The point y, Z, and X also lie along the same diagonal, these are also collinear.

The correct choice is B
