Answer: 1 gallon
Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
just use the standart recursive for geometric sequence
I think the answer is
B. ) 4/5 of the balls in the bag are red.
37 ?%
---- = ----
148 100
37*100=3700
--------- = 25% <---hope this helps
148
-0.5p-2=p
Add 0.5 to both sides which would equal
-2=1.5p
Then divide -2 by 1.5p
P=-1.33333333
