You are buying potato chips at the grocery store. You have a manufacturer’s coupon for $1.00 off and the store is offering 20% o
yarga [219]
You take your cost of the chips (Lets say it is 2.50 a bag so $5 for two bags).
20% off means it will be at 80% of the full price so you multiply 

5 x 0.8 = 4

Now if you add in  the discount of your $1 coupon, you have 4 - 1 = 3 so your final answer would be $3. 

(Keep in mind, I was given no cost for the chips so I made one up. This is just to explain the procedure.)

a medium sandwich is 5/8 foot long.A small sandwich is 4 7/8 inches.how many inches longer is the medium than the small
Stells [14]

Answer:

2.62 inches.

Step-by-step explanation:

For calculating the fraction by which the medium sandwich is larger than the smaller one you need to Subtract the length of smaller sandwich from the medium sandwich. During subtraction it is necessary that the units of length in both the sandwich should be same because quantities with same units only can be added or subtracted.

So, We will convert the length of each sandwich in inches first.

Length of medium sandwich = \frac{5}{8} feet = 7.5 inches

Length of small sandwich = 4\frac{7}{8} inches = 4.88

Difference in length = 7.50 - 4.88 = 2.62 inches.

So the medium sandwich is 2.62 inches longer than the small sandwich.

  A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians

To convert an angle in degrees to one in radians, multiply by π/180°.

Your 135° sector has an area of ...

  A = (1/2)(4 m)²(135°)(π/180°) = 6π m²

  A ≈ 18.8 m²
