2 combinations using the entire budget would be 3 pairs of Jordans and 4 pairs of Adidas, and 2 pairs of Jordans and 8 pairs of Adidas; 1 combination under budget would be 2 pairs of Jordans and 4 pairs of Adidas; and 1 combination over budget would be 4 pairs of Jordans and 4 pairs of Adidas.
Given that Sean has an annual shoe budget of $ 640 and on average, a pair of Jordans cost $ 160, and a pair of Adidas cost $ 40, to provide 2 combinations that use his entire budget, 1 combination that would be under budget, and 1 combination that would be over his budget, the following calculations must be made:
Using the entire budget:
- Combination 1 = 3 x 160 + 4 x 40 = 640 = 3 pairs of Jordans and 4 pairs of Adidas
- Combination 2 = 2 x 160 + 8 x 40 = 640 = 2 pairs of Jordans and 8 pairs of Adidas
- Combination 3 = 1 x 160 + 12 x 40 = 640 = 1 pair of Jordans and 12 pairs of Adidas
Under budget:
2 x 160 + 4 x 40 = 480 = 2 pairs of Jordans and 4 pairs of Adidas
Over budget:
4 x 160 + 4 x 40 = 800 = 4 pairs of Jordans and 4 pairs of Adidas

Answer:
<u>Area = 34.2 cm²</u>
Step-by-step explanation:
The general formula of the area of the triangle is half the product of two sides multiplied by the sine the angle between them.
So, for the given triangle ABC
AC = 9 cm, AB = 8 cm, CB = 10 cm
Area = 0.5 AC * AB * sin A or 0.5 BC * BA * sin B or = 0.5 CA * CB * sin C
Using the first form, so we need the measure of angle A
Using cosine low: cos A = (b² + c² - a²)/(2bc)
Where: a = BC = 10 , b = AC = 9 and c = AB = 8
So. cos A = (9² + 8² - 10²)/(2 * 9 * 8 ) = 0.3125
∠A = cos⁻¹0.3125 = 71.79°
So, Area = 0.5 AC * AB * sin A = 0.5 * 9 * 8 * sin 71.79° = 34.2 cm²
<u>So, Area = 34.2 cm²</u> to the nearest one decimal place
0.7= 7/10
0.71= 71/100
Just choose a fraction between those two.
