Answer:
Step-by-step explanation:
Given
Fireplace is in the form of semi-ellipse  with height of 3 ft from center
Length of base=8 ft
if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis
2 a =8 
a=4 ft
If contractor cover the whole base
then total length of string=2a =8 ft
(b)String should be nailed at focus
focus of ellipse is a e
where e=eccentricity 


Focus 
Thus string should be nailed at 2.64 m from center
 
        
             
        
        
        
Hey there! I'm happy to help! 
Let's look at our diameters.

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

Therefore, your answer is 50.
Have a wonderful day! :D
 
        
                    
             
        
        
        
Answer:
$40.50 for the miles and 1.75 x P (passangers)
Step-by-step explanation:
Since $2.25 is the fee for miles, 2.25 x 18 = $40.50
and since it depends on the group, ima say its probably 3, the passenger fee would be $5.25
that would add up to about $45.75
but if there is a different amount of passengers, just multiply it by $1.75 then add it to $40.50!
 
        
             
        
        
        
To show how you decided, the simple way would be to draw a picture. Create 2 rectangles of the same length and divide them up according to the fraction. Then shade the number of pieces for the numerator and compare both fractions. Whichever is longer is the greater fraction.
