Answer:

875 ft^3

Step-by-step explanation:

Pick them apart starting at the bottom. The formul used is V=lwh

Starting at the bottom we have we have a sqare of 5 ft = 5ft^3= V = 125 ft^3

Then we have a rectangular prism: 5 x 5 x 20 = V = 500 ft^3

Third we have 5 x 5 x 10 = V = 250 ft3

125+500+250 = 875 ft^3

kiruha [24]

Answer:

25%

Step-by-step explanation:

let the Market Price of the Watch (M.P.) be x

CP for Rahim=x-[(20/100)*x]

CP = (1 *x) /5 = 4x/5

SP for Rahim = MP = x

Difference (Profit) = SP-CP = x - (4x/5) = (5x - 4x)/5 = x/5

Profit % = (Profit/CP) * 100

Profit % = (x/5)/(4x/5) * 100

Profit % = 25 %

Find the quotient and the remainder: (x^2+3x-4)/(x-1)

skelet666 [1.2K]

Evaluate this...
$\frac{x^2+3x-4}{x-1}$
the x at the bottom cancels out one of the xs at the top so it will be
$\frac{x^2+2x-4}{-1}$
Now the one cancels out one of the 1s in the -4 so
${x^2+2x-3}$

Hope this helps :)
