Answer: The store receive 3 ounces of peanuts. <em>(Please tell me if you get the answer correct. ^^)</em>
Let x be the number of refrigerators
Y be the number of pianos
So the inequality:
300x + 475y < 7100
So substitute 12 and 8 to the inequality
300(12) + 475(8) < 7100
3600 + 3800 < 7100
7400 < 7100 is not true
So it will overload the truck
4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
First try it out yourself then compare answers. Remember, all squares have the same length per each side.
a) 3025
b) 25300
Multiply the amount of the discount by pairs of shoes:
21.75 x 7 = 152.25
Add that to the total she spent:
152.25 + 654.50 = 806.75
Divide the total by pairs of shoes:
806.75/7 = $115.25
The answer is C. $115.25
