Answer:
![A(x) = 2x^2-22x+144](https://tex.z-dn.net/?f=A%28x%29%20%3D%202x%5E2-22x%2B144)
Step-by-step explanation:
We are given the following in the question:
Area of room =
![3x^2 + 2x](https://tex.z-dn.net/?f=3x%5E2%20%2B%202x)
Area of rug =
![x^2 + 24x - 144](https://tex.z-dn.net/?f=x%5E2%20%2B%2024x%20-%20144)
We have to find the area of of the room not covered by the rug.
Area of of the room not covered by the rug =
Area of room - Area of rug
![A(x)=(3x^2 + 2x) - ( x^2 + 24x - 144)\\A(x)=3x^2 + 2x-x^2 -24x + 144\\A(x)=(3x^2-x^2)+(2x -24x) + 144\\A(x)=2x^2-22x+144](https://tex.z-dn.net/?f=A%28x%29%3D%283x%5E2%20%2B%202x%29%20-%20%28%20x%5E2%20%2B%2024x%20-%20144%29%5C%5CA%28x%29%3D3x%5E2%20%2B%202x-x%5E2%20%20-24x%20%2B%20144%5C%5CA%28x%29%3D%283x%5E2-x%5E2%29%2B%282x%20-24x%29%20%2B%20144%5C%5CA%28x%29%3D2x%5E2-22x%2B144)
is the required expression for the area of floor not covered by the rug.
Answer:
The opening price of the stock in the beginning of the day was $4.
Step-by-step explanation:
To be able to calculate the price of the stock at the beginning of the day, you have to consider that the equation to calculate the final price is equal to the opening price multiply for the result of one plus the increase or decrease percentage, which is:
final price=opening price*(1+0.04)
Now, you know that the final price is $4.16, so you can replace this value in the formula and solve for the opening price:
4.16=opening price*1.04
opening price=4.16/1.04
opening price=4
According to this, the answer is that the opening price of the stock in the beginning of the day was $4.
Where is the question I wanna help u PLZ
En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.
Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:
- Cuánto dinero gastó en total = valores x fracción comprada
- 3 x 1/4 + 120 x 1 1/2 + 6 x 1/3 + 45 x 4/8 = X
- 0.75 + 180 + 2 + 22.5 = X
- 205.25 = X
- Si 4/8 de queso cuestan $45, y 4/8 es igual a 1/2, 1 kilo de queso cuesta $90 (45 x 2).
- Si 1 kilo de jamón cuestan $120, 1/2 kilo de jamón cuesta $60 (120 / 2).
- Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129 (3 + 6 + 120).
- Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas (120 x 3 + 45 + 3 x 5 + 6 + 6 x 0.666).
