A savings account offers 0.7% interest compounded bimonthly. If $110 is deposited in this account, what will the balance be after 15 years?​

Answers

Answer:

$111.15

Step-by-step explanation:

Using the formula for calculating compound interest

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

A = 110(1+0.007/(1/24))^15(1/24)

A = 110(1+0.0168)^0.625

A = 110(1.0168)^0.625

A = 110(1.010)

A = 111.15

Hence the balance after 15 years is $111.15

What is the answer to this problem? Abby had $6.00 to spend on a treat with his 3 friends. If he spends the same amount on his 3 friends, what is his maximum amount of money he can spend on each person?

Answers

Answer:

$2.00

Step-by-step explanation:

Abby had $6.00 to spend on a treat with his 3 friends.

We are told in the question that: If he spends the same amount on his 3 friends

Hence: the maximum amount of money he can spend on each person is calculated as:

$6.00/3 friends

= $2.00

Therefore, the maximum amount of money that he can spend on each friend is $2.00

Answers

Step-by-step explanation:

The given equations are :

y=-x+2  ....(1)

y = -4x +7 ....(2)

From equation (1) and (2)

-x+2 = -4x +7

Taking like terms together

-x+4x=7-2

3x = 5

x = 1.667

Put the value of x in equation (1)

y=-(1.667)+2

y = 0.333

The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.

HELP ME I CAN’T FIGURE IT OUT!!

Answers

Answer:

B is right

Step-by-step explanation:

To add the fractions you need common denominators (the number at the bottom of the fraction) so the 12 is the common denominator. since the denominator on the bottom which is 4 turns into 12, you divide those and get 3. Once you get 3 you multiply it by the top number of 4 which is 9. Same with the next fraction which equals 10/12. Lastly, you add the top numbers together only since the bottom is already simplified. And.. 19/12 equals 1 7/12 because theres is 12/12 in 19/12 and leaves 7 extra which is 1 7/12

Answer:

3/4=9/12.      5/6 10/12

Step-by-step explanation:

ok this is easy so when it puts you 3/4 = /12 and 5/6 = /12

all you have to do is

multiply 4 times 3 for the bottom to get 12 and multiply 3 on top to

so 3/4 = 9/12

and for 5/6 = /12 you have to multiply 6 times 2 to get 12 so you multiply 2 on top as well so 5/6 = 10/12
