Answer:

88

Step-by-step explanation:

f(t) = 103 / ( 1 + 26 * e^{-0.3t})

here t = 17 years

f(17) = 103 / ( 1 + 26 * e^{-0.3*17})

= 103 / (1 + 26 * e^{-5.1})

= 103 / (1 + 26 * 0.00610)

= 103 / (1 + 0.1586)

= 103 / 1.1586

= 88.9003

As number of bears should be integer

I guess 88 or 89

Answer:

m∠X = 29°

m∠V = 61°

m∠W == 90°⇒given

Step-by-step explanation:

∵ ΔXWV is right angle at W

∴ m∠W = 90°

∴ m∠X + m∠V = 180° - 90° = 90°

∵ m∠X = 2x + 5 and m∠V = 4x +13

∴ 2x + 5 +4x + 13 = 90

∴ 6x + 18 = 90

∴ 6x = 90 - 18 =72

∴ x = 72/6 = 12

∴ m∠X = 2(12) + 5 = 29°

∴ m∠V = 4(12) + 13 = 61°

An apartment building produces $4,000 per quarter in gross rents. The maintenance expenses run $350 per month. Property taxes ar
S_A_V [24]

Answer:

0.16%

Step-by-step explanation:

Cost of rent per quarter = $4000

Cost of rent per year = 4×$4000

= $16,000

This means that the apartment building produces $12,000 per year in gross rents.

Yearly Expenses are as follows;

Maintenance expenses per year = 12×$350 = $4200

Property taxes per year = $1,750

Mortgage payment per year = 12×$650 = $7800

Total expenses per year = sum of all the yearly expenses

= $4200+$1,750+$7800

= $13750

Yearly revenue generated = Cost of rent per year - total yearly expenses

= $16,000-$13750

= $2250 (net operating income)

Capitalization rate is given as the ratio of the net operating income to the market value of the building.

Capitalization rate = net operating income/market value of building

Since the building with $83750, that will be its market value

Cap rate = $13750/$83750

Cap rate = 0.16%

There are 81 band members.  :-)

4 rows of 20 = 80 ... with one left over   = 80 + 1  (81)
6 rows of 13 = 78 ... with three left over = 78 + 3  (81)
7 rows of 11 = 77 ... with four left over   = 77 + 4  (81)
