Answer:
(a,a)
Step-by-step explanation:
Keep in mind that the vertical line represents the y axis and the horizontal line represents the x axis
We want to find the coordinates of C
We can do this by looking at the given coordinates and the axis..
We are given that B is at (0,a) and we are given that D is at (a,0)
Now looking at C, we can tell that C shares the same y value as B and the same x value as D
If B has a y value of a and D has an x value of a then C would have an x and y value of a
Hence C would be at (a,a)
To find cirfumfrence we use the formula C =

Soooo

= 3.14
r = 40 inches
So now we plug it in :P
C = 2 x 3.14 x 40 = 251.2
answer = B.) 251.2 inches
15 miles 2.5 x 6 because 1/4th of an hour is 15 minutes 15 x6 = an hour and a half
Answer:
y = 
Step-by-step explanation:
Squaring a number means multiplying the number by itself. 0*0=0. 1*1=1. 2*2=4, and 3*3=9. This is the pattern shown in the table.
3-in plus 1.5-out every minute means a net gain of 1.5 per minute. You need to fill (12 - 3) = 9 gallons. At 1.5 per minute, it takes 9/1.5 = 6 minutes if the drain and the faucet arr both open, but only (9/3)=3 minutes if you close the drain while you fill the tub.
