Answer:
75.5
Step-by-step explanation:
First, the picture is not to scale.
The Area of the bottom (2) rectangle is 33
base x height = A
11 x 3 = 33 (where did I get 3? Total height of shape is 8. Trapezoid is 5)
(8-5 = 3)
Area of the trapezoid:
A = 
= 
= 
= 
= 42.5
42.5 + 33 = 75.5
Answer: b: 2/5=2.5 for 1 day
Step-by-step explanation:
b: 2 ÷ 5 = 2.5 (for 1 day)
5 x 2.5 = 12.5
12 x 2.5 = 30
Answer:
2.462
Step-by-step explanation:
I added up the decimals.
2+0.4=2.4
2.4+0.06=2.46
2.46+0.002=2.462
And I got 2.462 as my final sum.
Subtract both sides from 6x, leaving you with the equation:
-2y=-6x+12
Now, you divide all of the sides by -2, therefore leabing you with the equation:
y=3x-6
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
Hope this helps.
