An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.

Answers

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

Answers

Answer:

13) C (a, a)  Y (a, 0)

14) B (0, b)  P (a, 0)

Step-by-step explanation:

13) Y lies on x axis so it is Y(a,0)

ZY = YC = a

so for C coordinates are (ZY,YC) = (a, a)

14) B lies on y axis so it is B(0, b)

BK = BP = [tex]\sqrt{a^{2} + b^{2} }[/tex] = distance between two points

so P is (a, 0) as it is same distance and on positive side of x axis

Marcus has earned 353 out of 400 points (88% or B+) in Math class. He needs 90% to earn an A-. There is one test left worth 100 points. How many points does Marcus need on the test to raise his grade to an A-?

Answers

Answer:

97

Step-by-step explanation:

Marcus is aiming for an A- (90-94 percent). The question states that there is another test awaiting that is worth 100 points. In order to find the answer to the question, you need to:

1.) Add 400 + 100, to show how many points there are in total.

2.) Use the answer choices and add it to 353.

88 + 353 = 441

93 + 353 = 446

97 + 353 = 450

3.) Find the percentage of the sums.

441/500 = 88%

446/500 = 89%

450/500 = 90%

Since Marcus is aiming for an A-, we can conclude that obtaining 97 points will help Marcus achieve an A-.
