Imagine the path of the tip of the pendulum as an arc of a circle. The circle would have a radius of 4 feet and the arc would be 20 degrees. To calculate the length of the arc, you need to find 20 degrees of the circumference. 

Length of Arc = 2*pi*R*Degree of arc/360 
Length of Arc = 2*pi*4*20/360 
Length of Arc = 8pi * 1/18 
Length of Arc = 4/9 pi feet 
<span>Length of Arc ~ 1.396263402 feet

Fiona has $18 to spend. She spent $4.25, including tax, to buy a notebook. She needs to save $9.75, but she wants to buy a snack
chubhunter [2.5K]
18-4.25=13.75 the original minus what she already spent

13.75-9.75=4 that minus what she has to save

.50x=4 where x=the number of packages

divide both sides by .50
x=8 Fiona can buy 8 packages of crackers

Hope that helps.

Rewrite the decimal number as a fraction with 1 in the denominator<span>
$1.00 = <span>$1.00/1
</span></span>
<span><span /></span>Multiply to remove 0 decimal places. Here, you multiply top and bottom by 10^0
<span><span>$1.00/1 </span>×<span> 1/1</span> = <span>1/1
</span></span>
<span><span /></span>Simplify the improper fraction, <span>= 1

The total cost of a shirt and a tie was $75.62. if the price of the shirt was $4.02 less than the tie, what was the price of the
kifflom [539]
--------------------------------------------
Define x:
--------------------------------------------
Let the tie be x
Tie = x
Shirt = x - 4.02

--------------------------------------------
Construct equation :
 --------------------------------------------
The sum of the shirt and tie is $75.62
x + x -4.02 = 75.62
2x - 4.02 = 75.62
2x = 79.64
x = $39.82

--------------------------------------------
Find the cost of tie and shirt :
--------------------------------------------
Tie = x = $39.82
Shirt = x - $4.02 = $39.82 - $4.02 = $35.80

----------------------------------------------------------------------------------------
Answer: The price of the short is $35.80

Chemist has an empty cylinder with a height of 30 cm and a cone shaped flask. The flask is the same height and a base that is th
Nookie1986 [14]
It fills the cylinder up to 10 cm.

The volume of a cylinder is given by the formula
V = πr²h, where r is the radius of the base and h is the height of the cylinder.

The volume of a cone is given by the formula 
V = 1/3πr²h, where r is the radius of the base and h is the height of the cylinder.

Since the base of the flask and the cylinder are the same, this means r is the same number in both formulas.
Since the height of the flask and the cylinder are the same, this means h is the same number in both formulas.

This means that the only difference in the formulas is that the formula for the cone flask is 1/3 the formula for the cylinder.

The water that fills the cone flask will fill 1/3 of the cylinder; 1/3(30) = 10
