Aura built a scale model of a building using a scale in which 4 inches represents 60 feet. The height of the building is 420 feet.
What is the height of the scale model in inches?
Answer:
28 inches
Step-by-step explanation:
We're told that each 60 ft is represented by 4 inches of model. 420 feet is 7 times 60 feet, so the model will be 7 times 4 inches.
The height of the scale model is 28 inches.

PLZZZZZ HELP ME. How many solutions does 2x - 1 = 2x + 3 have? One? Zero? Or Infinite? PLZ HELP ME ITS DUE IN 10 MINSS!!!!!!!!!!!!!!!!!!
Answer:
No Solution
Step-by-step explanation:
2x - 1 = 2x + 3 Combine the like terms.
0 = 4 Sine this mathematical statement is false (i.e. 0 is not equal to 4), no value of x would satisfy the equation. So there is no solution.
a company can model the profit it makes on selling an item at price x by using the expression 2000x - 10,500. a second item sold at the same price brings in a profit og 1850x - 11,600. write and simplify an expression that reflects the total profit from the sale of both items
Profits are simply the difference between the selling price and the cost price of an item.
The expression that represents the total profit is 3850x - 22100
The profit (p1) on the first item is given as:
[tex]p_1 = 2000x - 10500[/tex]
The profit (p2) on the second item is given as:
[tex]p_2 = 1850x - 11600[/tex]
So, the total profit (p) on the sales of both items is:
[tex]p = p_1 + p_2[/tex]
Substitute known values
[tex]p = 2000x - 10500 + 1850x - 11600[/tex]
Collect like terms
[tex]p = 2000x + 1850x- 10500 - 11600[/tex]
[tex]p = 3850x-22100[/tex]
Hence, the expression that represents the total profit is 3850x - 22100

Cooper drove his car for 2 hours at a constant speed of 60 miles per hour and then for another 30 minutes at a constant speed of 40 miles per hour. How far did Cooper drive?
100 miles
170 miles
180 miles
160 miles
Answer:
None of the answer choices show the correct answer.
The actual answer is 140 miles.
Step-by-step explanation:
Since Cooper drove 60 miles per hour for 2 hours, that means that he drove 120 miles for the first 2 hours.
60 * 2 = 120
Cooper then drove for another 30 minutes at a speed of 40 miles per hour.
30 minutes is half of and hour so we need to divide the 40 miles by 2.
40 / 2 = 20
Now we just have to add them together.
120 + 20 = 140
So the answer is 140 miles.
Hope this helps! :)

Answer the following for 10 points
Answer:
Regional metamorphism
Step-by-step explanation:
(all definitions below are NOT my own definitions, but burrowed from trustworthy informational sites)
It is not Sediment Layering because Sediment Layering is sedimentary rocks layers are piled one on top of the other.
It is not Cooling of Magman because Cooling of Magman is elements within the magma combine and crystalize into minerals that form an igneous rock.
It is not Contact Metamorphism because Contact Metamorphism is metamorphism due to contact with or proximity to an igneous intrusion.
It IS regional metamorphism because it is metamorphism affecting rocks over an extensive area as a result of the large-scale action of heat and pressure.

Which is the graph of f(x) = 2(3)*?
Answer:
First option (top left)
Step-by-step explanation:
Since the coefficient of this equation, [tex]2(3)^{x}[/tex], is 2, when x is 0, then y must be 2. The graph must have a y-intercept of 2. You can find this by plugging this in.
I cannot see the fourth graph, but the second graph does not have a y-intercept of 2, therefore it can immedeately be ruled out.
Then we plug in the coordinates they give.
It just so happens that the first one, [tex]2(3)^1[/tex] is indeed equal to 6.
We can check that this is right by disproving the third one (top right).
[tex]2(3)^2=18[/tex], not 8, therefore our third answer choice is false.
The fourth one is definetly wrong because the y-value at x=2 (as we have already calculated) is 18, not 12.
Therefore, our first answer, the one on the top left, is correct.
note: for this problem you did not even need to find the y-intercepts. Plugging in the coordinates would be fine by its own (the second answer choice is already wrong just because of the coordinates since 9≠6(found in answer choice 1)). However, having the y-intercept handy will be very helpful if there is more than one answer choice with correct coordinates.
