Find the amount accumulated after investing a principal P for t years at an interest rate compounded k times per year. P = $3,50

telo118 [61]

Answer:

A = 5,752.60

Step-by-step explanation:

P = $3,500

r= 5%

t = 10

k = 4

A = P(1 + r/k)^kt

= 3,500(1 + 0.05/4)^4*10

= 3,500(1 + 0.0125)^40

= 3,500(1.0125)^40

= 3,500(1.6436)

= 5,752.6

A = 5,752.60

Please help really fast :)

olasank [31]

Answer:

Step-by-step explanation:

The two smaller angles add up to the measure of the total angle, so

(like a lot of geometry) it is really just an Algebra 1 problem with a nice picture to go with it ---> (5x + 13°) + (3x + 33°) = 70°

8x + 46° = 70°

8x = 24°

x = 3°

There is no actual question shown, but I imagine you want one or more of the following:

x = 3°

∠ABC = 3(3°) + 33° = 9°+ 33° = 42°

∠CBD = 5(3°) + 13° = 15° + 13° = 28°

Hope this helps.

Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Then she donates $2 to clean wate

Sauron [17]

Charges for filing each tax return not through the easiest form = $35

Charges for the filing each tax return through the easiest form = $0

Donation made to clean water project for each tax return filed = $2

Let total tax returns filed be 'a' and total tax returns filed at $35 be 'b'

⇒ Tax returns filed at $0 = a-b

Total money charged by Sterre = $7, 245

Total donation made by Sterre = $1, 242

Now, first we will determine the total tax returns filed by Sterre

Total donation made by Sterre = Donation made per tax return × Total returns filed by Sterre

⇒ 1,242 = 2 × a

⇒ a = 621

Hence, Sterre filed total of 621 tax returns

Now total money charged by Sterre = Charges for filing each tax return not through the easiest form × Tax returns filed at $35

⇒ 7,245 = 35 * b

⇒ b = 207

Hence, Sterre filed 207 returns at $35.

⇒ Tax returns filed at $0 = 621 - 207

⇒ Tax returns filed at $0 = 414

Hence, at $35, Sterre filed 207 tax returns, and at $0 Sterre filed 414 tax returns.
