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 Since opening the account, Michelle's father has never deposited or withdrawn money from it.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
Michelle's age = 16

Answer:
88°
Step-by-step explanation:
5a + 18 + 24 - a + 8a - 30 = 180 (angles on a straight line)
=> 12a + 12 = 180
=> 12a = 168
=> a = 168 / 12
=> a = 14
5a + 18 = 5 (14) + 18 = 70 + 18 = 88
24 - a = 24 - 14 = 10
8a - 30 = 8 (14) - 30 = 112 - 30 = 82
Therefore, largest angle is 88°.

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