Answer:
1. Naomi spends more
2. Naomi spends $0.59 more
3. total cost is $27.98
4. with 20 dollars Naomi gets $5.72 change back
5. with 15 dollars Demetrius will get $1.30 change back
Step-by-step explanation:
Naomi's total cost:$14.28
0.39+0.79+0.59+(0.79x3)+(0.79x3)+0.39+0.39+6.99=14.28
Demetrius' total cost:$13.70
(0.79x5)+0.79+0.79+(0.59x3)+(0.59x5)+0.59+0.89+0.59+0.59+0.79=13.7

Answer:
41.29 cm²
Step-by-step explanation:
From the question,
Area of the shaded portion = Area of the circle - area of the square.
A' = πr²-L²...… Equation 1
Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie
Given: r = 4 cm, L = 3 cm
Constant: π = 22/7.
Substitute these values into equation 1
A' = [(22/7)×4²]-3²
A' = 50.29-9
A' = 41.29 cm²
Hence the area of the shaded portion is 41.29 cm²
Well, 1 Liter plus 1.5 Liters equals 2.5 Liters. We know that milli means 1000, so there are 1000 milliliters in a liters, so, all we have to do is multiply 2.5 liters by 1000 to get 2,500 milliliters!
2 3/4 x 8 1/4 = <u>22 11/16</u>
hope this helps!
