There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
cricket20 [7]
  To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag) 
5/25 x 100% (because you're trying to find probability of red) 
= 20% 

2) 5 + 8 = 13 (# of red AND blue) 
13/25 x 100% (divide out of the total) 
=52% 

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green) 
0.2 x 0.48 x 100% 
= 9.6% 

4) 10 + 12 + 28 = 50 (to find total number of trials) 
28/50 x 100% 
= 56% 

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner) 
= 35</span><span>Its B 20%

The graph of the function B is shown below. If B(x) = -1, then what is x?
Harlamova29_29 [7]

x = 2, that is B(2) = - 1

From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2

That is the point (2, - 1 )

The complete question is
<span>There are two flavors of ice cream; strawberry and chocolate. the amount of strawberry ice cream is in the shape of a sphere. the amount of chocolate ice cream fills the rest of the cone. the dimensions of the sphere is 6cm and the cone is 12cm.

the figure is not drawn to scale  

A. what is the volume, in cubic centimeters of the right circular cone ?show or explain how you got your answer.
B. the amount of strawberry ice cream is in the shape of a sphere. what is the volume in cubic centimeters of the strawberry ice cream?
C. what is the total volume in cubic centimeters of all the ice creams?
D.the amount of chocolate ice cream fills the rest of the cone. what is the volume in cubic centimeters of the chocolate ice cream?  

we know that
the height of the cone is 12 cm
the diameter of a cone is 6 cm

Part A) </span>what is the volume, in cubic centimeters of the right circular cone? show or explain how you got your answer.

we know that
the volume of a cone=(1/3)*pi*r²*h
r=6/2----> 3 cm
h=12 cm
The volume of a cone=(1/3)*pi*3²*12------> 36*pi cm³-------> 113.04 cm³

the answer part A) is 36*pi cm³  (113.04 cm³)

Part B) the amount of strawberry ice cream is in the shape of a sphere. what is the volume in cubic centimeters of the strawberry ice cream?
volume of a sphere=(4/3)*pi*r³
r=3 cm
volume of a sphere=(4/3)*pi*3³-----> 36*pi cm³------> 113.04 cm³

the answer part B) is 36*pi cm³  (113.04 cm³)

Part C) what is the total volume in cubic centimeters of all the ice creams?
volume of the cone+volume of a hemisphere

36*pi+18*pi-----> 54*pi cm³-------> 169.56 cm³

the answer Part C) is 54*pi cm³ (169.56 cm³)

Part D) .the amount of chocolate ice cream fills the rest of the cone. what is the volume in cubic centimeters of the chocolate ice cream?
volume of a cone-volume of a hemisphere
36*pi-18*pi-----> 18*pi cm³-----> 56.52 cm³

the answer Part D) is 18*pi cm³ (56.52 cm³)
