Answer:

D. $4000

Step-by-step explanation:

Initial value of the car is given $5000

Salvage value given $500

Useful life of car given is 5 years

Formula

Depreciation for n years is given as:

$d_{n}= \textrm{Salvage value}\times \textrm{Number of years used}$

$d_{n}=\textrm{Salvage Value}\times n$

Plug in 2 for n. This gives,

$d_{2}=500\times 2=1000$

∴ Depreciation after 2 years =$ 1000

Value of car after 2 years = Initial value - Depreciation after 2 years

Value of car after 2 years = $5000- 1000=4000$

Therefore, value of car after 2 years = $ 4000

Are the graphs 8x+3y=6 and 8x-3y=6 perpendicular

Alla [95]

Lines are perpendicular if the slope of one is the negative reciprocal of the other. In this case the slopes are -8/3 and 8/3, so while negative they are not reciprocal. So no, the two lines intersect but are not perpendicular.

A company has 10 male and 11 female employees, and needs to nominate 2 men and 2 women for the company bowling team. How many di

Anvisha [2.4K]

2475 different teams can be formed.

Combination is the way in which items can be selected from a collection. If we have n total objects and r objects want to be selected, the number of combinations is:

$C(n,r)=\frac{n!}{(n-r)!(r)!}$

Since we need to nominate 2 men from a company of 10 males, the number of ways this can be done = $C(10,2)=\frac{10!}{(10-2)!(2)!} =45\ ways$

Also, we need to nominate 2 women from a company of 11 females, the number of ways this can be done = $C(10,2)=\frac{11!}{(11-2)!(2)!} =55\ ways$

Therefore the total number of different teams that can be formed = 45 ways * 55 ways = 2475 ways

4 students is what percentage of 20 students?2 doctors is _____% of 25 doctors.

Ray Of Light [21]

In both cases, we can use a rule of three.

<h2>First part</h2> $\begin{gathered} 20\text{ students}\rightarrow100\text{\%} \\ 4\text{ students}\rightarrow x \\ x=\frac{4\text{ students}\cdot100\text{\%}}{20\text{ students}} \\ x=\frac{4\cdot100\text{\%}}{20} \\ x=\frac{400\text{\%}}{20} \\ x=20\text{\%} \end{gathered}$

Therefore, 4 students correspond to 20% of 20 students in total.

<h2>Second part</h2> $\begin{gathered} 25\text{ doctors}\rightarrow100\text{\%} \\ 2\text{ doctors}\rightarrow x \\ x=\frac{2\text{ doctors}\cdot100\text{\%}}{25\text{ doctors}} \\ x=\frac{2\cdot100\text{\%}}{25} \\ x=\frac{200\text{\%}}{25} \\ x=8\text{\%} \end{gathered}$

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
