Answer:
$34.20
Step-by-step explanation:
First, find the cost with tax 
You are paying 7.2% tax, but you are also paying for 100% of the bill 
100%+7.2%=107.2% 
So, you are really paying for 107.2% of the bill 
Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right 
107.2/100=1.072 
Multiply the decimal by the cost of the bill 
1.072*45.90=49.2048
But, we also have a coupon for $15 off
Subtract 15 from the cost with tax 
49.2048-15=34.2048
Round to the nearest cent/hundreth 
$34.20 
Hope this helps! :)
 
        
             
        
        
        
1260. You do 1200*.05= 60. Then 1200+60=1260
        
                    
             
        
        
        
Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw 
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth

Answer:
   50 ft
Step-by-step explanation:
The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.
In this geometry, that means the length of the escalator is 2 times its height, so is ...
   x = 2(25 ft)
   x = 50 ft . . . . . distance a person travels
 
        
             
        
        
        
Answer:
Translated 1 to the right and up one
Step-by-step explanation:
When the number is inside the parenthesis with x, that value represents a horizontal shift. because the original equation is (x-h), the opposite sign of the x value must be taken. so in this case the x value would be +1 because that is the opposite of -1, which means the function is being moved one to the right. when the number is being added to the outiside of the parenthesis, then you take that value for the vertical translations of the graph. because the original equation is (x-h)+k, then in this case there would be a vertical shift up by 1
