Answer: 12 degrees

Step-by-step explanation: So the temperature decreases every hour by 3 degrees for 4 hours. So the first hour, the temperature will have decreased by 3. Then by the second hour, the overall temperature will have decreased by 6. The third hour, the overall temperature will be 8 degrees less, and finally on the fourth hour, it will have decreased by 12.

If Peter withdrew $47.27 from the bank and deposited $598, how would his bank account change? (Indicate how much his account wou
fredd [130]

Answer:

Since we do not know the balance we should start with, a general answer:

b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Step-by-step explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals

How much is 80% from 250.00
rodikova [14]
If you need further help on how they got the answer, this equation will take more time, but it will also help you understand these types of problems. Part÷Whole=Percent÷100
Part= X because it is what you are trying to find.
Whole=250 because it is what you are taking the percentage of.
Percent=80
Now you have:
X÷250=80÷100
Set this up in fraction form and cross multiply.
You get:
100x=250×80
250×80=20,000
100x=20,000
X=200

Someone plz help I don’t even know what this means
Vikentia [17]
What you wanna do here is use a calculator, as "e" in mathematics refers to the "e" on a calculator. The tricky part about this question is that the answer for the equation is the given percentage, NOT the value for "x". From there, plug in the multiple choice answers for "x" and see which one works!

In this case, A is the correct answer. B is absurdly large, so I omitted it immediately in the attached picture.
