(0,-3) because that’s what it is
It would be 3:40 since 1 hour and the 40 minutes add up and the choir is after the meeting
First we write equation for perimeter of rectangle. Why? because we have been given that it is 128 units and maybe we can calculate something from it.
P = 2a + 2b where
a = 2(3y + 1 ) and b = 2(2y +3)
P = 6y + 2 + 4y + 6 = 10y + 8 = 128
now we can solve for y
10y = 120
y = 12
Now we just express value of y in formula for finding lenght of VW and we got length
Answer is 37
multiply the number of blocks by number of people per block
Then divide number of pizza places by that
1st block:
15 blocks x 220 people = 220*15 = 3300
26 pizza places = 26/3300 = 0.0078
2nd Block
175 * 22 =3850
33/3850 = 0.0085
the first one is just under 0.008 but if you round it to 3 places it is 0.008
the 2nd are is just over 0.008 ( 0.009 if you round it to 3 places)
so they would be better off building in the first area, if they build at all.
Use the rules of indices
When they are dividing we subtract the exponents provided the bases are the same.
Since the bases are the same,
(2/3)^5 ÷ (2/3)¹
Will be
(2/3)^5-1
= (2/3)⁴
= 16/81
Hope this helps.
