For part A. 0.85
For part b. 11.9
Explain
Cost of each track in album A= total cost downloading album a/ total number of track
The problem give us a has 11 trackers and the total cost of download is 9.35 pounds
9.35/11
= 0.85
Now we are given each track cost in album b cost the same as track on A
Cost of each track in album B is 0.85
Now we are given if Jane download album B , B will be 14 tracks
Total cost of downloading is album B= number of tracks in album Bx cost of each track in album B
14x0.85 pound
= 11.9
Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
Height = 10 units
Radius = 10 units
Volume = π × 10² × 10
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
Height = 10 units
Base = 10 units
Volume = 1/3 × π × 10² × 10
Since the cone has been carved from the cylinder, the statement that derives the formula to find the volume of container B is
π × 10² × 10 - 1/3 × π × 10² × 10
Step-by-step explanation:
This can be rewritten as
If we will solve this way,
But since the denominator is just in terms of 1, we can just simply get the (-3). Note that we have to take the negative into consideration.
From the original position of the decimal point, move the decimal point 3 times TO THE LEFT. Therefore, from 2.71 we move the decimal point 3 times to the left, 0.00271.
If the exponent has a positive value, move TO THE RIGHT.
For example,
Note that the exponent has a positive value. Therefore, we have to move the decimal point 3 times TO THE RIGHT. Producing 2710 as the answer.
The square root of 142 is 11.916
