Integer that describes debit of $40
Sladkaya [172]
Alright - we want to start off by seeing if this number would be positive or negative. Debit means that you owe something, or that you have to pay that amount of money. If you had money to buy things with, that would be positive, but since debit means you haven’t paid something off yet, that is negative. Next, since you have 40 dollars in debt, you have -40 dollars.

The sum of two confescutive integers is at least 46. What is the least possibly pair of integers?
dezoksy [38]
An integer is a whole number. Sum means to add and since they are consecutive, there is only a difference of 1 between them.

1) 21 + 23: not consecutive
2) 23+24= 47: has to be at least 46
3) 22+23= 45: has to be at least 46
4) 24+25= 49: has to be at least 46

So we have two possibilities: either #2 or #4. Find least possible pair of integers.

x= first integer
x+1= second integer

x + (x+1) >= 46
2x + 1 >=46
2x>=45
x>=22.5

Answer:
The first integer has to be greater than or equal to 22.5. Since integers are whole numbers, round up to the next whole number. The least possible integers are #2) 23 and 24.

Hope this helps! :)

Toby just graduated from four years of college. at the beginning of each year, he took out a stafford loan with a principal of $
Mila [183]

If he starts paying after four years, the worth of the loans by then is b. $31,616.16

<h3>What is a Loan?</h3>

This refers to the amount collected from a lender to be repaid after a given time, usually with added interest.

Hence, we can see that:

The effective monthly interest rate is:

i = 0.053/12 = 0.0044

The effective annual interest rate is:

i = (1 + 0.0044)^12 -1 = 0.0543

The present worth of all the loans is:

P = 6125 + 6125 (1 + 0.0543)^-1 + 6125 (1 + 0.0543)^-2 + 6125(1 + 0.0543)^-3

P = $22,671.40

If he pays them prompty, then the total lifetime cost would be

P = 22671.40 (1 + 0.0543)^4 = $31,616.16

Which expression illustrates the associative property of addition?
4vir4ik [10]

Answer: THIRD OPTION.

Step-by-step explanation:

The Associative property of addition states that when three or more numbers are added, it does not matter how they are grouped, the sum is the same. Then:

a + (b + c) = (a + b) + c

Based on this and having the expression 3 + 19- 12, we can apply the Associative property as following:

(3 + 19) - 12 = 3 + (19 - 12)

Therefore, the  expression that illustrates the Associative property of addition is the one shown in the Third option.
