The value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original va
Setler79 [48]

Well, there is actually a formula for this kind of exercises:

n is the price the land had in the third year year

2500=n-nx0.6

2500=n(1-0.6)

2500=nx0.4

n=2500:0.4

n=6250

m is the price the land had in the second year

6250=m-mx0.6

6250=m(1-0.6)

6250=nx0.4

p=6250:0.4

p=15625

p is the price the land had in the first year

15625=p-px0.6

15625=p(1-0.6)

15625=px0.4

p=15625:0.4

p=39,062.5 <- this should be your answer. Hope this helps.

I need help with this problem please ​
Gwar [14]

Answer:

  (a) reduction

  (b) 1/2

Step-by-step explanation:

The image figure A'B'C'D' is smaller than the original figure ABCD, so the dilation is a <em>reduction</em>.

Each of the points A'B'C'D' is half as far from the origin as the original points ABCD, so the scale factor is 1/2.

_____

Draw lines C'C and D'D. You will see they meet at the origin, which is the center of dilation. Then look at how far the points are along those lines. C' is one grid square diagonal along the line; C is 2 grid square diagonals along that line, so is twice as far from the origin. That is, C' is 1/2 the distance of C, so represents a reduction by a scale factor of 1/2.

The same distance considerations are observed along the line D'D. The point D' is the diagonal of a 2x1 rectangle from the origin (A distance of √5.) The point D is the diagonal of a 4x2 rectangle from the origin, so is twice as far. Once again D' is 1/2 the distance of D, so represents a reduction by a factor of 1/2.

I have a total of 11 pencils = total outcome
a- since we have 6 Red, P(Red)=6/11
b- P(Black) = 3/11
c- P(Green) = 1/11
For the dice:
Total outcome 6 so :
P(3) =1/6
P(1) =1/6
P(less than5) means P( of 1 OR 2 OR 3 Or 4)
Since we have "OR" it means we can add the P(probabilities)====>
P( of 1 OR 2 OR 3 Or 4)=1/6+1/6+1/6+1/6=
= 4/6 = 2/3
