Answer:
$14.9
Step-by-step explanation:
Step one:
given data
we are told that Emma borrowed $89.40 from her sister to pay her back in 6 months.
let us solve for the amount she is to pay her sister every month.
amount to be paid per month= 89.40/6
=$14.9
So that every month she pays back her sister $14.9
we don't know her balance but every month there will be a deduction.
Hence the monthly change in her balance is reflected by a deduction of $14.9
The time it will take the principal to grow to the desired amount is 0.7 years
Using the compound interest formula :
A = P(1 + r/n)^(nt)
A = final amount = 225,000
P = principal = 180,000
r = rate = 3.12%
n = Number of compounding times per period = 12(monthly)
t = time
225000 = 180000(1 + (0.0312 /12))^(12t)
Divide both sides by 180000
225000/180000 = (1 + (0.0312 /12))^(12t)
1.25 = 1.026^12t
Take the log of both sides
0.0969100 = 0.0111473 × 12t
0.0969100 = 0.1337676t
Divide both sides by 0.1337676 to isolate t
0.0969100 / 0.1337676 = t
0.7244 years
0.7 years
It will take 0.7 years for the amount to grow

Answer:
26
Step-by-step explanation:
Answer:
<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between, we can calculate for ∠A using the sine law:
</em>
<em>
</em>
<em>b / sin B = a / sin A
</em>
<em>
</em>
<em>2.45 / sin 60 = 2 / sin A
</em>
<em>
</em>
<em>sin A = 0.707
</em>
<em>
</em>
<em>A = 45˚
</em>
<em>
</em>
<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>
