Answer:
8:27
Step-by-step explanation:
1 way to do it is...
The volume of a sphere is 4/3*pi*r^3. Plugging in 2 and 3 in for the radii you get the volumes are about 33.51 and 113.1, which is an 8:27 ratio.
Another way to do it is...
The ratio of the radii is 2:3 and a radius is 1-dimensional. The volume, however is 3-dimensional. To get from 1-D to 3-D, you have to cube the numbers. 2^3 is 8 and 3^3 is 27, so the ration is 8:27.
Answer:
P(A or B) = P(A) + P(B) - P(A and B)
0.87 = 0.8 + P(B) - 0.23
0.87 = P(B) + 0.57
P(B) + 0.57 = 0.87
P(B) + 0.57-0.57 = 0.87-0.57
P(B) = 0.3
Answer: 0.3
Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.
PLEASE MARK BRAINLIEST AND VERTIFIED ANSWER!! I spent a lot of time on this... :P thank you!!
For number one, you will divide 15.7 by 5. This is becuase all the strawberries are the same size and mass. This will give you 3.14 or choice C.
For number 2, you will divide 35.37 by three because there are 3 shirts for the same price. This will give you 11.79 or choice C.
For number 3, you will divide 1.28 by 16 since there are 16 of the same size cookies. This will give you 0.08 or choice B.
