Nick starts with 20 milligrams of a radioactive substance. The amount of the substance decreases by 12 each week for a number of

The moon does, as it is significantly larger than all of these combined.

Calculating gives us 73 - 27 = 46

Next, 46 / 100 × 2628 = 1208

Adding together gives 2628 + 1208 = 3836

Answer: 470.85 gallons

Step-by-step explanation:

12.9 gal/min multiplied by 36.5 min equals 470.85 gal

We understand that a rectangle has been altered into the one shown in Figure 1 using this rule:



It is known that the origin is the center of rotation and two rules apply to perform a rotation of 90 degrees, namely:

1. Clockwise

The rule to convert a point in this case is:



This rule has already been implemented to create the image, so we need to reverse the outcome using this formula, hence:



2. Counterclockwise

Applying the same concept as before but with new rules for the scenario:



Reversing the outcome gives us:
