Target: ratio of pizza places / person < 0.01
<span>The
population of 15 blocks of the north side of town is 221 people per
block, but there are already 32 pizza places in the area.
population = 15*221 = 3,315
ratio: 32 pizza places / 3315 people = 0.0097 pizza places per person
Which indeed is less than 0.01 => this area is good for their purpose.
The population
of 22 blocks of the south area is 150 people per block, and there are
28 pizza places in the area.</span>
population: 22*150 = 3300
ratio: 28 pizza places / 3300 people = 0.00085 which is also less than 0.01
Both places meet the target of less than 0.01 places per person, but the south area seems better than north area.
Answer:
x = 1
Step-by-step explanation:
7x + 16 = 8x + 15
<u>Step 1</u> : Subtract 15 on both sides
7x + 16 - 15 = 8x
7x + 1 = 8x
<u>Step 2</u> : Subtract 7x on both sides
1 = 8x - 7x
1 = 1x
x = 1
Answer:
There are 15600 ways to pick a password
Step-by-step explanation:
We have 26 possibilities to pick a letter. So, we have 26 possibilities for the first component of the password. The second letter should be different from the first one, so we have one less possibility, giving us a total of 25, and for the third letter we have 24.
This gives us 26*25*24 = 15600 ways of picking a password.
Answer:
Total distance Rory drive = 300 +142 = 442 miles
and total distance her cousin drive = 142 miles.
Step-by-step explanation:
Total distance traveled by Rory and her cousins = 584 miles
Distance drive by Rory herself first day = 300 miles
Distance left to travel = total distance - distance drive by Rory
= ( 584-300 ) miles
= 284 miles.
According to the question, The second day, Rory and her cousin will share driving equally.
Let the distance traveled by cousin is S miles, then, Rory also drive S miles.
⇒ S + S = 284
⇒ 2S = 284
⇒ S = 142
So they will divide the remaining distance of 284 miles among them equally that is they both drive 142 miles.
Total distance Rory drive = 300 +142 = 442 miles
and total distance her cousin drive = 142 miles.
