A student buys a guitar that is on sale for 15% off the regular price of $200. He also must pay an 8% sales tax. What is his tot

EastWind [94]

Answer:

option c

Step-by-step explanation:

a guitar 15% off means that the cost is now 85%

$100percent---200dollars\\85percent---x\:dollars\\\\x=\frac{200*85}{100}\\\\x=2*85\\\\x=170$

now the 8% of 170 is

$100\:percent---170\:dollars\\\\8\:percent---x\:dollars$

$x=\frac{8*170}{100}\\\\x=\frac{8*17}{10}\\\\x=13.6$

so the total cost is

170+13.6

183.6

Of the 48 oranges in a carton 1/3 of them were rotten Ben and David took the remaining good oranges it's been took eat my orange

Burka [1]

Answer:

David took 16 oranges.

Step-by-step explanation:

We are given the following in the question:

Total number of oranges = 48

Oranges rotten =

$\dfrac{1}{3}$

Number of oranges rotten =

$\dfrac{1}{3}\times 48\\\\=16$

There were 16 rotten oranges.

Number of good oranges left =

$= 48-16\\=32$

These are equally divided among Ben and David.

Number of oranges each Ben and David get =

$\dfrac{32}{2} = 16$

Thus, David took 16 oranges.

In a race from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X. Sa

svlad2 [7]

Answer:

Sandy will finish the race first.

Step-by-step explanation:

Let D be the total one sided distance in miles, ( between X and Y ),

We know that,

$Speed =\frac{Distance}{Time}$

$\implies Time =\frac{Distance}{Speed}$

Since, from point X to point Y and back, Jack averages 30 miles per hour to point Y and 10 miles per hour back to point X.

So, the total time taken by Jack = $\frac{D}{30}+\frac{D}{10}$

$=\frac{D+3D}{30}$

$=\frac{4D}{30}$

$=0.1333D$

Also, Sandy averages 20 miles per hour in both directions,

So, the total time taken by Sandy = $\frac{D}{20}+\frac{D}{20}$

$=\frac{D+D}{20}$

$=\frac{2D}{20}$

$=\frac{D}{10}$

$=0.10D$

∵ 0.133D > 0.10D

Hence, Sandy will finish the race first.
