Answer:
A Between 0-1/2
Step-by-step explanation:
Because you don't know if the rug is solid white or a checkard rug. But I could be wrong with insufficient evidence of the rug
Answer:
The ratio for the surface areas is equal to 4
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z -----> the scale factor
In this problem
The scale factor is equal to
----> the ratio of its corresponding radii or its corresponding altitudes
step 2
Find the ratio for the surface areas of the cones
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z -----> the scale factor
x ----> the surface area of the larger cone
y ----> the surface area of the smaller cone
we have
substitute
The ratio for the surface areas is equal to 4
That means-----> The surface area of the larger cone is 4 times the surface area of the smaller cone
What will the radius of your cake be?
This is a problem of geometry. Given that the cake is circular, the greater the cake the greater the radius of it. So, as shown in the figure 1, the radius will be the distance from the center to any extreme point of the circle.
How many slices will you be able to cut?
The total area of a circle is given by:
We need to fin how many slices will be cut, so let's calculate the area of the circular sector which can be obtained simply applying rule of three, so:
Let's name n the number of slices, if we divide the total area by n this result, each area must equal, then:
Finally, we will be able to cut:
Slices
<h3>the mean of data </h3>
<h3>total odd number = 4 </h3>
<h3>number = 17 , 9 11 , 7 </h3><h3>so ,</h3><h3>17 +9+11 + 7 / 4 </h3>
<h3>= 44 / 4 </h3>
<h3>so for find mean divide the number </h3>
<h3>= 11 </h3>
<h2>so mean of data is = 11 </h2>
<h3>11 is your answer </h3>
