Answer: all the ones that do not have a negative sign in front easy.
To Calculate the cost of <span>The cost of fertilizing, we need to Calculate first the Area of the Triangle.
</span>the Area of the Triangle = 1/2 x base x altitude = 1/2 x (14+√17) x 68 = 524.08 <span>square foot
</span>The cost of fertilizing = the cost of the square foot x the total area = 0.25x524.08 = 131 <span>$</span>
Answer:
y =1/2x+6
y = -2x+2
Step-by-step explanation:
Perpendicular line have slopes that multiply to -1
The slopes are negative reciprocals
-4*4 = 16 not perpendicular
1/2 * -2 = -1 perpendicular
1/5 *5 = 1 not perpendicular
2/3 * 2/3 = 4/9 not perpendicular
Answer:
22.5
Step-by-step explanation:
y=kx
20=k15
k=1•33
30=1•33x
x=22•5
Divide the price by the quantity:
Bananas = 5.40 / 6 = 0.90 each
Oranges = 2.56/8 = 0.32 each
Apples = 4.68 / 12 = 0.39 each
Mangos = 3.16 / 4 = 0.79 each
Oranges have the lowest price each so are the best buy.
