To convert any decimal number into a fraction simply divide it by 1 and follow it with as many zeros as there are numbers after the decimal point.
In this case we will divide 0.725 by 1000 (three digits <725> after the decimal point)
0.725÷1000 = 5/8
if for example you had 0.75 and had to convert it into fractions, you would divide it by 100 (because only two digits after the decimal point)
Answer:
Step-by-step explanation:
Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.
Write it out in a line: 3m + 12 - 8m -2
Simplify: -5m +10
Divide by -5 again to simplify further: m - 2
Largest Angle: 85 Degrees
Middle-Sized Angle: 51 Degrees
Smallest Angle: 44 Degrees
Knowing that all the angles in a triangle add up to a total of 180 degrees and the relation of all angles to one another: you may plug in a value for the smallest angle and use this to calculate the other angle values, add all calculated angle measures and repeat until the value is equal to 180 degrees.
Since all angle measures in this problem are dependent upon the smallest angle measure, you only have to change the value of this variable in order to solve the problem.
I was a little confused myself but if it is asking for the cost of the sneakers after the 20% off from the amount of money the store had to pay, it would be D, $21.84. The way to do this would be to find the cost of the sneakers when the store bought them. You multiply the percentage in decimal form with the cost of the sneakers at the price the store was selling it: 0.3*39 = 11.7. Then, to get the price the store bought them at, you would subtract that price from $39 to get $27.30. Finally, you apply the 20% discount to 27.30 by multiplying 0.2 to it and subtracting that price from 27.30. Then your answer will be $21.84. However, if the problem was asking for the cost of sneakers after the 20% off from the price the store was selling it, it would be A, $31.20. You would have to multiply the 20% discount straight to the price the store is selling the sneakers, $39. Then subtract that price from $39 to get $31.20.
