Answers

17 and 44

Step-by-step explanation:

[X is smaller number Y is bigger number]

y-x=27 3x=7+y y-17=27

y=27+x 3x=7+27+x y=44

3x=34+x

2x=34 x=17

Michelle's father deposited $1,000 into a savings account when she was born. The annual interest rate is

4.5%. Since opening the account, Michelle's father has never deposited or withdrawn money from it.

What age will Michelle be when her account reaches more than $2,000?

Answers

Answer:

Michelle's age = 16

Step-by-step explanation:

As we know,

Amount = [tex]P (1 + r)^{t}[/tex] where

P = Principal amount

r = rate of interest

t = time

Given ,

P = $1000

r = 4.5 % = [tex]\frac{4.5}{100} = 0.045[/tex]

Now,

Given that Amount reaches more than $2000

⇒[tex]P (1 + r)^{t}[/tex]  > 2000

⇒[tex]1000(1 + 0.045)^{t}[/tex] > 2000

⇒[tex](1.045)^{t}[/tex] > 2

Now,

we put the value of t from 0 , 1, 2, ..... untill the above equation does not satisfy

Now,

for t = 0

[tex](1.045)^{0} = 1 \ngeq 2[/tex]

for t = 1

[tex](1.045)^{1} = 1.045 \ngeq 2[/tex]

for t = 2

[tex](1.045)^{2} = 1.092 \ngeq 2[/tex]

for t = 3

[tex](1.045)^{3} = 1.14 \ngeq 2[/tex]

for t = 4

[tex](1.045)^{4} = 1.19 \ngeq 2[/tex]

for t = 5

[tex](1.045)^{5} = 1.25 \ngeq 2[/tex]

for t = 6

[tex](1.045)^{6} = 1.30 \ngeq 2[/tex]

for t = 7

[tex](1.045)^{7} = 1.36 \ngeq 2[/tex]

for t = 8

[tex](1.045)^{8} = 1.42 \ngeq 2[/tex]

for t = 9

[tex](1.045)^{9} = 1.48 \ngeq 2[/tex]

for t = 10

[tex](1.045)^{10} = 1.55 \ngeq 2[/tex]

for t = 11

[tex](1.045)^{11} = 1.62 \ngeq 2[/tex]  

for t = 12

[tex](1.045)^{12} = 1.69 \ngeq 2[/tex]

for t = 13

[tex](1.045)^{13} = 1.77 \ngeq 2[/tex]

for t = 14

[tex](1.045)^{14} = 1.85 \ngeq 2[/tex]  

for t = 15

[tex](1.045)^{15} = 1.93 \ngeq 2[/tex]

for t = 16

[tex](1.045)^{16} = 2.02 > 2[/tex]

It satisfies at t= 16

∴ we get

Morris serves juice at breakfast for himself and 5 friends. Each person receives 6 ounces of juice. Which equation shows how many ounces of juice Morris needs?

Answers

Answer:

36

Step-by-step explanation:

because if 6x6=36

5x + 10y = -5
-5 - y = 32

Answers

y= -27
x= 53

solving for y:

-5-y=32

add y to both sides

-y = 27

divide by -1

y= -27

solving for x

plug in -27 for y in the first equation

5x +10(-27) =-5

5x+ (-270) =-5

add 270 to both sides

5x= 265

divide by 5 on both sides

x= 53

1. Bill decided to buy six books on history instead

of four books on politics. It follows, then, that

the opportunity cost of each history book was ______

books on politics.

Answers

Answer: 2/3 books on politics

Step-by-step explanation:

The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.

Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.

= Number of politics books / Number of history  books

= 4 / 6

= 2/3 books on politics

Bill gave up 2/3 books on politics to get a single history book.
