Answer:
6
Step-by-step explanation:
You are looking for the cross section of ask three circles. This is true for the smallest part, with the number 6 in it.
This can be solved by making an equivalent ratio.
The original ratio is what we know, 15 inches of wire for 90 cents.
In a ratio of inches of wire:cents, this would be 15:90.
Now for the equivalent ratio.
We don't know the number in the inches place but we do know it for the cents place.
Let's use x to represent inches of wire.
x:48 is our new ratio, and we need to find x.
Since x:48 and 15:90 are equivalent, that means the same thing that was done to 90 to get 48 has to be done to 15 to get the value of x, since the same thing must be applied to both sides.
We can find what 90 was divided by (which is what we'll have to divide 15 by) by dividing 90 by 48.
90 / 48 = 1.875
This means 48 • 1.875 = 90 and x • 1.875 = 15.
Since we don't know x though, we can isolate it by dividing both sides by 1.875.
x • 1.875 = 15
x • 1.875 / 1.875 = x
15 / 1.875 = 8
So x is 8.
Answer:
While you can be 15 inches of wire for 90 cents, you can buy 8 inches of wire for 48 cents at the same rate.
Answer:
680
Step-by-step explanation:
Use the binomial coefficient where you choose 
numbers out of 
possible numbers and find the total amount of combinations since order does not matter:
Thus, you can make 680 three-non-repeating-number codes
Answer:
-2.46, -10/4, 14/5, 2.5.
Step-by-step explanation:
The Point at which the Function g(t) = 2t - 6 crosses x axis is where g(t) = 0
Because on x-axis : y - coordinate is zero
As g(t) is the y - coordinate and t is the x - coordinate :
⇒ g(t) = 0
⇒ 2t - 6 = 0
⇒ 2t = 6
⇒ t = 3
