Pleas help Calculate the shaded area give your answer to 3 significant figures
IgorC [24]

Answer:

116 cm²

Step-by-step explanation:

Shaded Area = area of the larger circle - area of the smaller circle

Area of the larger circle = πr²

Where,

r = 6.5 cm

Area = π*6.5² = 42.25π cm²

Area of smaller circle = πr²

Where,

r = 2.3 cm

Area = π*2.3² = 5.29π cm²

✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264

Area = 116 cm² (3 S.F)

When originally purchased, a vehicle costing $23,000 had an estimated useful life of 8 years and an estimated salvage value of $
earnstyle [38]
The <u>correct answer</u> is:

$5,000.

Explanation:

When it is first purchased, the depreciation expense is calculated using the formula:

\text{Depreciation expense}=\frac{\text{Cost}-\text{Salvage Value}}{\text{Useful Life}}

The cost was $23,000; the salvage value was $3,000; and the useful life was 8 years:

\text{Depreciation Expense}=\frac{23000-3000}{8}=\frac{20000}{8}= \$2500

This means the value of the vehicle depreciates $2500 per year.

After 4 years, the vehicle would depreciate 2500(4) = $10,000.

This makes the new value $23000-$10000 = $13000.

Reevaluating the depreciation expense at this point, we use $13000 for the "cost" (current value), $3000 is still the salvage value, and now the total useful life was 6; we take 4 off of this, since it has already been 4 years:

\text{Depreciation Expense}=\frac{13000-3000}{6-4}=\frac{10000}{2}= \$5000

The depreciation expense in year 5 is $5,000.

Sarah's rectangular garden has a perimeter of 3 27 +3 27 +258 +218 cm
nirvana33 [79]

Alright , so basically the permiter that is given is like this:

327+327 +258+258 cm = 1170cm

now this can also be written as: 2(327+258)cm =1170cm

wait, its given as 258 and 218 cm. the width should be same actually , then only you can simplify it in order to get it in an expression ( simplest form)
