Answers

Answer 1

Answer: Put it as a fraction first so it is 240/600. Now all you need to do is get the denominater (600) to 100. Divide 600 by 100 to find out what you need to divide the top by. 600/100= 6. Divide the 240 by 6 to get 40. So the fraction is 40/100 which can then be converted into a percentage. Your answer is 40%.

5. Melanie put $5000 in a savings account that pays 1.25% interest compounded yearly. How much money will be in the account 10 years later if she makes no more deposits or withdrawals?

Answers

Answer: $5661 will be in the account 10 years later

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 5000

r = 1.25% = 1.25/100 = 0.0125

n = 1 because it was compounded once in a year.

t = 10 years

Therefore,

A = 5000(1 + 0.0125/1)^1 × 10

A = 5000(1.0125)^10

A = $5661

Solve each system by elimination:
10x+8y= -18
8x+8y= -24

Answers

Answer:

Step-by-step explanation:

10x + 8y = -18

-8x - 8y = 24

2x = 6

x = 3

8(3) + 8y = -24

24 + 8y = -24

8y = -48

y = -6

(3, -6)

(3,-6) would be the answer to this question

HELP QUICK Jamie created a list of factors of 32. 32: 1, 2, 4, 6, 8, 16, 32 which number should be removed from the list to make the list accurate? 1 6 16 32

Answers

Answer:

Step-by-step explanation:

1: divide 32 by each factor

2:ensure that the answer is a whole number

3: 6, when calculated gives you 5.3(and the threes will go on)

4:You get your answer

Answer:

Step-by-step explanation:

The factors listed shows that 1 x 32 = 32, 2x 16= 32, 4 x 8= 32

BUT! When we get to 6 it does not have a number to multiply to that is a whole number. For example, 32/6= 5.333 which is not a whole number. Factors have to be whole numbers and no decimals! So, 6 should be removed from the list to make it accurate!
