Answer:
$60
Step-by-step explanation:
We can create a proportion to find the markup from original price to the marked up price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked up by 20% so we pay 120% of $50.
![\frac{120}{100} =\frac{x}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B100%7D%20%3D%5Cfrac%7Bx%7D%7B50%7D)
We begin solving by cross multiplying numerator to denominator of each fraction.
![120(50)=100(x)\\6000=100x\\\frac{6000}{100}=\frac{100x}{100} \\60=x](https://tex.z-dn.net/?f=120%2850%29%3D100%28x%29%5C%5C6000%3D100x%5C%5C%5Cfrac%7B6000%7D%7B100%7D%3D%5Cfrac%7B100x%7D%7B100%7D%20%20%5C%5C60%3Dx)
Each shirt cost $25 dollars because 10 plus 65 is 75 and divided by three is 25
Answer:
The area of the sector is 17/2 π
Step-by-step explanation:
pi = π
To solve this problem we first have to find the fraction that corresponds to this angle of the total, for this we must divide the angle that they give us by 2π radians, since that is the angle of a circle
(17π/9 rad) / (2π rad) = 17/18
Now we multiply the area of the circle by this fraction and we will obtain the area of the sector that we want
9π * 17/18 = 17/2 π
The area of the sector is 17/2 π
The number in the set that is a natural number is 402
