Answer:
B. .
Step-by-step explanation:
Let x represent the smaller number.
We have been one number is five more than another. The another number would be: .
Sum of both numbers would be
Three times the smaller number would be .
Three less than three times the smaller number would be .
We have been given that their sum is three less than three times the smaller. We can represent this information in an equation as: .
Therefore, option B is the correct choice.
Answer:
The cup can hold <u>235.5 cubic cm</u> of popcorn.
Step-by-step explanation:
Given:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius ( r ) = 5 cm.
Height ( h ) = 9 cm.
π = 3.14 ( as per question ).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Therefore, the cup can hold 235.5 cubic cm of popcorn.
