Peter purchases a baseball card for $150 as an investment. His research tells him that the value of

creativ13 [48]

Answer:

6 years

Step-by-step explanation:

Given

$Initial\ Investment = 150$

$Ratio = double$

Required

When will it get to 4000

This question illustrates a geometric progression and will be solved using:

$T_n = ar^{n-1}$

In this case;

$T_n = 4000$

$r = double = 2$

$a = 150$

So, we're to solve for n

$4000 = 150 * 2^{n - 1}$

Divide through by 150

$\frac{4000}{150} = 2^{n-1}$

$26.67= 2^{n-1}$

Take Log of both sides

$Log26.67= Log2^{n-1}$

Apply law of logarithm

$Log26.67= ({n-1})Log2$

Take Log values

$1.42602301569 = (n - 1) * 0.30102999566$

Make n - 1 the subject

$n - 1 = \frac{1.42602301569}{0.30102999566}$

$n - 1 = 4.73714591984$

Add 2 to both sides

$n = 1 + 4.73714591984$

$n = 5.73714591984$

$n = 6$ (Approximated)

<em>Hence, it'll take 6 years</em>

Marci needs to rent a storage unit. She needs to determine the volume of the storage unit to decide if the storage unit is big e

stealth61 [152]

Answer:

$Volume = 176ft^3$

Step-by-step explanation:

Given

$Height = 8$

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

<u>CDEF</u>

$EF = CD = BD - BC = 5 - 2 = 3$

$ED = FC = FG +AB = 4 + 2 =6$

So, the area of CDEF is:

$Area = EF * ED$

$Area = 3 * 6$

$Area = 18$

<u>ABCG</u>

<u></u> $AB= GC = 2$ <u></u>

<u></u> $AG = BC = 2$ <u></u>

<u></u>

<u></u> $Area = AB * AG$ <u></u>

$Area = 2 * 2$

$Area = 4$

So, the base area is:

$Base\ Area = 18 + 4$

$Base\ Area = 22$

The volume is then calculated as:

$Volume = Base\ Area * Height$

$Volume = 22 * 8$

$Volume = 176$

david quiere saber cuanto requiere invertir mensualmente para obtener $30,760.08 durante 6 meses si los invierte con el 12% capi

Akimi4 [234]

Answer:

A = $32,652.44

Step-by-step explanation:

Given: Principal (P) = 30,760.08, Annual Rate (R) = 12%, Time (t in years) = 0.5

To find: How much David needs to invest monthly

Formula: $A = P(1 + r/n)^n^t$

Solution: To find, simply add principal + interest

First, convert R as a percent to r as a decimal

r = R/100

r = 12/100

r = 0.12 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 30,760.08(1 + 0.12/12)(12)(0.5)

A = 30,760.08(1 + 0.01)(6)

A = $32,652.44

Therefore;

The total amount David will obtain with 30,760.08 for 6 months, 12%is $32,652.44.
