Let x be the months and y be the cost.
Rate of increase of commodity A = 6/3 = $2 per month
Equation:
y = 2x + 4500
Rate of increase of commodity B = 2/4 = $0.5 per month
Equation:
y = 0.5x + 5400
Equating the costs,
2x + 4500 = 0.5x + 5400
1.5x = 900
x = 600 months
x = 600 / 12 = 50 years
Answer:
okay
Step-by-step explanation:
Answer:
1.) : You should buy the second one (16cm x 45cm)
2.) : Between the smallest and the biggest vases, the cone face holds 396 more water than the smallest one.
Step-by-step explanation:
10 x 40 = 400
16 x 45 = 720
18 x 18 = 324
———————
720 - 324 = 396
Answer:
0
Step-by-step explanation:
Slope = y2- y1/x2 - x1
Given
x1 = 6
y1 = -3
x2 = -4
y2 = -3
Slope = -3 -(-3) /-4 - 6
= -3 + 3 /-10
= 0/10
= 0
This means that the line of the slope is horizontal
Answer:240
Step-by-step explanation: Either multiply 400 by 6/10 or .6. Either way you get 240.
