So each of these statements are talking about the square footage of land per person. Let's go and find it!
First off, let's find the number in each building of the original complex:
280 people / 4 buildings
Each building has an equal number of residents. So just divide:
280/4 = 70.
So 70 residents per building
Now consider the fact that once a new building is built, another 70 people will move in.
280 + 70= 350
350 people total.
Then lets look at the plot of land
Originally, there are 200,000 square feet of land for the 4 buildings. Then after the expansion, the plot of land will be:
200,000 + 200*200
= 200,400
Go back to the question. What's the effect of the expansion in terms of square feet of land per person?
Divide!
200,400 / 350
Approximately = 572.57 square feet
Then since it's being compared to the amount each resident had before the expansion, do the same thing with the corresponding numbers:
200,000 / 280
Approximately = 714.29
So how much will each person's land decrease?
714.29 - 572.57 approximately = 141.72 square feet.
The answer is the first choice!
Hope this helps
Answer:
Step-by-step explanation:
We have an equation, and the question is asking for us to solve y. So to solve, we have to isolate y.
6x - 4y = 12
Subtract 6x from both sides :
-4y = 12 - 6x
Divide both sides by -4 :
Answer:
3 1/5
Step-by-step explanation:
Since the 12 pizzas are being cut into 8 slices each, that would be 12×8, which is 96. And if you're distributing those 96 slices evenly to 30 people, each person would get 3.2 slices. The mixed number version for 3.2 is 3 2/10, and if you simplify that, the answer would be 3 1/5 slices.
Answer: Chiara's monthly payment is $194.7
Step-by-step explanation:
The cost of the new natural gas barbecue for $2,100. She made a down payment 30% off the purchase price. This means that the amount of down payment made is
30/100 × 2100 = 0.3 × 2100 = $630
Amount left to pay would be
2100 - 630 = $1470
The formula for determining monthly loan payment is
A = P(r(1 + r)^n)/((1 + r)^n - 1)
There would be 9 monthly payments, so
n = 9
r = 0.055/12 = 0.0046
P = 1470
A = 1470(0.0046(1 + 0.0046)^9)/((1 + 0.0046)^9 - 1)
A = (1470 × 0.0049)/0.037
A = 7.203/0.037
A = 194.67
Answer: A) y = 7x
<u>Step-by-step explanation:</u>
In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates
A) 0 = 7(0) ---> 0 = 0 TRUE
B) 0 = 2 + 3(0) ---> 0 = 2 False
C) 0 = Vz(0) ---> Too many variables so False
D) 0 = 5 - 0 ---> 0 = 5 False
