A one-year-old car is now worth AED 12 000.
masha68 [24]

Answer:

AED 15,000

Step-by-step explanation:

Depreciation is a reduction in the value or worth of an asset as a result of use.

Given that the car is depreciated by 20%, it means that the value of the car after the application of depreciation is the result of the original price of the car less the amount of depreciation which has been given as 20% of the original price.

Let the original price of the car (its price when it was new) be T then

T - 0.2T = 12,000

0.8T = 12,000

T = 12,000/0.8

= AED 15,000

Amanda [17]

Answer:

17m

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

The following equation would be used: A=\frac{a+b}{2} h

We would simply substitute the given values, move the values around then we would get our answer:

230.945=18.7\frac{7.7+b}{2}\\\\230.945=9.35(7.7+b)\\\\b+7.7=24.7\\\\b=17m

Help me find the answer to this piecewise problem!! 20 Points !!!!
MrRissso [65]

Answer:

So we have x+3 if -3<=x<=-1

and                5   if   -1<=x<=1

Step-by-step explanation:

The one piece from -1 to 1 is horizontal so the line is in the form of y=a number.  It goes through 5 on the y-axis so the equation there is y=5.

From -3 to -1, that is a line with positive slope (since that part is increasing).

Slope=rise/run

We see from the filled in dot to the unfilled in dot that the rise is 2 and the run is 2 so the slope is 2/2=1.

So if we did extend this line where we go at on the y-axis?  It would go through 3 because starting from the unfilled dot and rising 1 and running 1 will get us to the 3 on the y-axis.

The equation of a line in slope-intercept form is y=mx+b.

We have m=1 and b=3 so the equation is y=1x+3 or just y=x+3.

So we have x+3 if -3<=x<=-1

and                5   if   -1<=x<=1
