The correct question is
A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is going to be circular with a radius of 4x. Once the fountain is built, what will be the area of the remaining yard?
Step 1
find the area of rectangular yard (A1)
A1=(10*x)*15*x=150*x² units²
Step 2
find the area of the circular <span>fountain (A2)
A2=pi*r</span>²---------> pi*(4x)²=16*pi*x²
Step 3
find <span> the area of the remaining yard (A3)
A3=A1-A2----------> 150*x</span>²-16*pi*x²----> x²*[150-16*pi]----> 2*x²*[75-8*pi]
the answer is the option A)
<span> 2x</span>²<span> (75-8pi )</span>
Answer:
C) About $85
Step-by-step explanation:
Please consider the complete question.
Carl puts $1.10 in his penny bank every day in the month of July (31 days). His total saving at the end of June is $55.00. What is the best estimate at the end of July?
A) about $25
B) about $115
C) about $85
D) about $66
First of all, we will round $1.10 to nearest whole number and round 31 to nearest tens as:
So amount saved in 30 days would be 30 times $1.
Carl's savings at the end of July would be amount saved in June plus amount saved in July that is
Therefore, the estimate for Carl's saving at the end of July is $85 and option C is the correct choice.
Or is it half empty tell me that
It can be simplified to B because it is in slope formula y-y over x-x hope this helps
