Answer:
Answer choice A
Step-by-step explanation:
For the first letter, there are 26 options, as there are for the second and third letter. For each of the three numbers, there are 10 digits to choose from. Therefore, 26*26*26*10*10*10=17,576,000, or answer choice A. Hope this helps!
Answer:
Your answers are:
A, B and C
Step-by-step explanation:
So 12 over 3 is equal to 4 which is a Whole number. meaning Not a fraction, an Integer is a whole number (not a fractional number) that can be positive, negative, or zero. Rational numbers would include this example as well

Read answer below :)
Step-by-step explanation:
So you know that it takes 90 seconds for 10 gallons, right? So you know it's 9 seconds per gallon, removing the 0's (which is the easiest way to simplify).
then you take 8 divided by 60 to find out how long it takes for one gallon.
My math shows this:
A = 9 seconds per 1 gallon
B = 7.5 seconds per 1 gallon
60 seconds for 8 gallons, 30 seconds for 4 gallons, 15 seconds for 2 gallons, 7.5 seconds for 1 gallon. (Notice how I divided by two each time until it was simplified)
For this case we can model the problem as a rectangle triangle.
We know:
Length of the hypotenuse
Angle between the base of the triangle and the hypotenuse.
We want to know:
Length of the base.
For this we use the following trigonometric relationship:
![cos (15) = \frac{x}{500} ](https://tex.z-dn.net/?f=cos%20%2815%29%20%3D%20%5Cfrac%7Bx%7D%7B500%7D%20%0A)
Clearing x we have:
![x = 500 * cos (15) x = 482.96](https://tex.z-dn.net/?f=x%20%3D%20500%20%2A%20cos%20%2815%29%0A%0Ax%20%3D%20482.96)
