Answer:
117.65%
Step-by-step explanation:
make the assumption that 646 is 100% since it is our output value.
step 2. we next represent the value we seek with x.
step 3 . from step 1 , it follows that 100%=646
step 4. in the same vein, x%=760
step 6. this gives us our pair of equations 100%=646(1)
x%=760(2)
step 6. by simply dividing equation 2 and by taking note of the fact that both the LHS (left hand side) of both equations have the some unit (%); we have 100%=646(1) and x%=760(2)2
step 7. taking the inverse (or reciprocal) of both sides yields 100%/x% = 646/760
= 117.65%
therefore , 760 is 117.65% of 646.
14.5 x 5.5x 0.5 = 39.875 cubic feet for the wall
brick = .5 x .333 x 0.167 = 0.0278 cubic feet rounded to 0.03
39.875/0.03 = 1329.16
so approximately 1330 bricks are required.
This could be a little different depending on how you round everything off

Answer:
C. 1365
Step-by-step explanation:
The expression nCr can be written with the simple equation:
n! / ((n-r)! * r!)
So to evaluate 15C4:
15! / ((15-4)! * 4!)
= 1365
So 15C4 = 1365
Cheers.
