When you ask, "What is 4.5 as a decimal?", we assume you want to know what 4.5 percent is as a decimal. In other words, 4.5 percent converted to decimal.
First, we will tell you why it is useful to know 4.5 as a decimal.
Normally, to calculate 4.5 percent, you would multiply a number by 4.5 percent and then you would take the product of that and divide it by 100 to get the answer.
Instead, you can simply multiply a number by 4.5 as a decimal to get the answer.
4.5 percent means 4.5 per hundred. Therefore, to get 4.5 as a decimal, all you have to do is divide 4.5 by 100 like so:
4.5 ÷ 100 = 0.045

Answer:
Let's calculate the "cups of sugar per dozen cookies" ratio:
2 cups
---------- = 0.8 (Rina)
2.5
2.25 cups
------------- = 0.75 (Jonah)
3
Rina uses more sugar for a dozen cookies.
The abscissa of the ordered pair, that is the x-coordinate, is equal to 1 and the ordinate, the y-coordinate, is equal to -1. In the cartesian plane, this point lies in the fourth (IV) quadrant. The standard position of the angle is that which has one of its side is in the x-axis.
Solve for the hypotenuse of the right triangle formed.
h = sqrt((-1)² + (1)²) = √2
Below items show the calculation for each of the trigonometric functions.
sin θ = opposite/hypotenuse = y/h = (-1)/(√2) = -√2/2
cos θ = adjacent/hypotenuse = x/h = (1)/√2 = √2/2
tan θ = opposite/adjacent = y/x = -1/1 = -1
