Answer:
22.95 kg
Step-by-step explanation:
Let's say the farm stand owner starts with x kg of apples.
During the first hour, he sells 15% of the apples:
0.15 x
This means he's left with 85% of the original apples. During the second hour, he sells 20% of the remaining apples:
0.20 (0.85 x)
= 0.17 x
He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples. Continuing the pattern, the apples sold during the third hour:
0.25 (0.68 x)
= 0.17 x
He's sold 49% of the apples and is left with 51%. The apples sold during the fourth hour:
0.30 (0.51 x)
= 0.153 x
If 0.17 x = 25.5, then x = 150. So the apples sold during the fourth hour is:
0.153 (150) = 22.95

Answer:
perfect square trinomial methodIf a polynomial has three terms, x2 + 12x + 36, which factoring method can be considered? Summary: If a polynomial has three terms, x2 + 12x + 36, the perfect square trinomial method can be considered to find the factor of the expression.
Answer:
<u>A = x² - 5x - 8</u>
Step-by-step explanation:
<u>Finding x</u>
- Area (deck) = Area (Rectangle) - [Area (bench) + Area (planter)]
- A = x(x - 4) - [ 2(6) + 1/2(2)(x - 4) ]
- A = x(x - 4) - [12 + x - 4]
- A = x² - 4x - 8 - x
- <u>A = x² - 5x - 8</u>
