Answer:
C.
Step-by-step explanation:
The answer states that she needs at least 52.50, this wording equating to it's equation having a greater than sign. This leaves us with B or C. It is most definitely not B as that involves addition which is not in use as of the given equation.
Hello there!
1. Okay. So 70% is positive, so it is a corresponding growth. 70% is 0.7 in decimal form. C and D are both eliminated, because that's too large. When something grows by 70%, that is less than double. 0.7 is not right either, because that's more of a decay than a growth. The only answer that makes sense id 1.70, because you are going up, and adding 1 to decimal form brings you to the decimal that when multiplied will bring you to the total. The answer is B: 1.70.
2. So, -75% is negative, so it is a decay factor. A is eliminated, because it makes no sense and B is out, because that represents growth, not decay. You lose 75% of the amount overtime compounded, but you still have 25% that remains. To find that amount, you would subtract that amount from 1 to get the decay. 1 - 0.75 is 0.25. The decay factor is 0.25. The answer is D: 0.25.
Answer:
Domain = -2, 0, 01,4
Range = (4,2,3,-2)
Step-by-step explanation:
In any set of ordered pair given in form of (x1,y1), (x2,y2)......
domain set of first values(x1,x2) in every pair for x (they can be termed as x coordinates)
range is set of second value in each pair (i.e y1, y2) ( they can be termed as y coordinates)
_____________________________________________
Given ordered pair
Q = {(-2. 4), (0.2). (-1,3), (4.-2)}
thus domain will be first number in each pair
domain = -2, 0, 01,4
Range will be first number in each pair
Range = (4,2,3,-2)
Answer:
8 pounds
Step-by-step explanation:
"purchased 3 pounds of mac and cheese for $7.50"
You would make this into an equation to figure out the price of one pound of mac and cheese (x):
7.50=3x
x=2.5
Next, you can create an equation to represent the price per pound.
Total price = 2.5(number of pounds)
Now, plug in the information you have:
20 = 2.5x
8=x
Answer: 2/3
