To answer this item, we let the number of small, medium, and large popcorns sold be equal to x, y, and z such that the total amount that can be obtained from the sales is,
2x + 3y + 4z = total sales
If the 9p is the total number of popcorns sold, the equation is,
x + y + z = 9p
Answer:
∠A = 70°, ∠B = 50°, and ∠C = 60°.
Step-by-step explanation:
In a triangle ΔABC, ∠A + ∠B + ∠C = 180° ......... (1), we know from the property of triangle.
Now, the sum of ∠C and the exterior angle adjacent to ∠C is 180°.
If the exterior angle adjacent to ∠C is 120°, then ∠C = 180° - 120° = 60°.
Now, from equation (1), ∠A + ∠B = 180° - ∠C = 180° - 60° = 120° ......... (2)
Now, given that ∠A = 2x and ∠B = x + 15.
Hence, from equation (2), we have, 2x + x + 15 = 120
⇒ 3x = 105
⇒ x = 35.
Therefore, ∠A = 2x = 2 × 35 = 70°
∠B = x + 15 = 35 + 15 = 50°
and ∠C = 60° (Answer)
Xy=80 would be right because it would be x=80/y and y=80/x
The measure of central tendency give you a picture of what to expect in a situation. For example, a basketball players average is the amount of points that they typical score.
In a business, you make decisions on what you expect to happen. Knowing the measure of center can help you make better decisions.
