The slope is undefined, if the line is vertical the slope equation m=(change in y)/(change in x) becomes undefined because youd be dividing by zero
The quick way to dispute something like this is to simply do the calculation and then create a ratio.
Cube One (Large Cube)
The formula for a cube is V = e^3
e = the measurement of an edge. In this case.
e = 10 cm
V = e^3
V = 10^3 = 10*10*10
V = 1000 cm^3
Cube 2 (Small Cube)
V = e^3
e = 5 cm
V = 5*5*5
V = 125 cm^3
Ratio
Large Cube / Small Cube = 1000 / 125 = 8/1.
The difference in size is 8 to 1 not 2 to 1.
Explanation
He's right if he sticks to one side. The ratio of one side of the large cube to the small one is 2 to 1. But once you put that into the formula for volume, three sides are multiplied together and that 2 shows up everytime you multiply the sides together.
First, you need to find the total amount they discounted.
3.66 X 3= $10.97
Since they took off that much, you need to add that to the total cost, which was 62. 31
62.31 + 10.97= $73.29
Finally, to find how much each individual shirt cost, you divided it by 3.
73.29 / 3= $24. 43
The answer is C
10 minutes I'm pretty sure. My calculations may be off but at least I tried
The square root of 0.0036 can be calculated through the calculator. The answer is 0.06. WE can also take by the eye the square root of 0.0036 in which the square root of 36 is 6. The number must be greater than 0.0036. The answer is 0.06.
