Answer:
There is a 25% markup
Step-by-step explanation:
First find the original cost of each shirt
$2400/ 100 shirts
$24/ shirt
Mark up = ( new price - original price) / original price
                = ( 30-24) / 24
                = 6/24
                = 1/4
                 = .25
                  25%
There is a 25% markup
 
        
                    
             
        
        
        
9.42 Units
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us  9.42
 
        
             
        
        
        
Answer:
Option c
 or
 or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function  x> 0 for all real numbers.
  x> 0 for all real numbers.
Then the inequation:
 has two cases
 has two cases
 if
    if  (i)
  (i)
 if
    if  (ii)
 (ii)
We solve the case (i)

We solve the case (ii)

Then the solution is:

You're nearly there. Just some more steps.
557 * x = 594 tells us 
x = 594 / 557 (divide both sides by 557)
x ≈ 1.066427
When we've found this number we must realise the following:
the '1' in this answer is the 100% the car fixing costs (without taxes)
the '0.66427' stands for the tax rate.
To find the tax rate we multiply 0.66427 by 100, which gives us:
0.66427 * 100 = 6.6427 ≈ 7
So, rounded to the nearest %, the tax rate is 7%
        
             
        
        
        
Answer:
Step-by-step explanation:
3/4 x 28=21   Madilyn built 21 toys.
1/7 x 28=4     Penelope built 4 toys.
21+4=25        25 toys have been built altogether.
28-25=3
There are 3 toys left to build.
