There is 5000 ml water in a fish tank. THen 20% water is evaporated per week. calculate the volume of water left after 4 Weeks.
LenaWriter [7]

Answer:

The answer to your question is: V = 2048 ml

Step-by-step explanation:

Data

Volume = 5000 ml

20% is evaporated per week

Volume of water left after 4 weeks = ?

Process

            1st week               5000 ml   -----------------  100 %

                                              x          -----------------      20 %

                                              x = (20x 5000) / 100

                                              x = 1000 ml

After a week there are = 5000 - 1000 = 4000 ml left

            2nd week              4000 ml   ----------------  100 %

                                                x          ----------------   20%

                                               x = 800 ml

After two weeks, there are = 4000 - 800 = 3200 ml left

         third weeks              3200 ml  -----------------  100 %

                                              x         ------------------    20%

                                             x = 640 ml

After three weeks there are 3200 - 640 = 2560 ml left

           

         4rd                             2560 ml  ----------------- 100%

                                                x           ----------------  20%

                                             x = 512 ml

After four weeks there are 2560 - 512 = 2048 ml left

After spending $30 on a dress, Mary had 3/8 of her money left. How much money did she have at first?
BaLLatris [955]
The answer is that she had 48.  Set it up as an equation with x as the amount of money she started with.  x - 30 = 3/8x.  That says, in words, "the amount of money she started with minus 30 for the dress left her with 3/8 of the money she started with.  Solve for x by adding 30 to both sides and subtracting 3/8 from 8/8x (8/8 = 1).  8/8 - 3/8 = 5/8, so 5/8x = 30, multiply both sides by 8 to get 5x=240 and x = 48.

Is it possible to have a triangle with 150 20 20 degrees angle and why ?
OLga [1]

No, it is not possible.  The total measure of all angles in a triangle must be 180.  If you add these three together, you get 190.

How are you in the bet nobody’s not going to help me on this question
Nataliya [291]

Answer:

See below.

Step-by-step explanation:

Party A

y = x^2 + 1

For each value of x in the table, substitute x in the equation with that value and evaluate y.

x = -2: y = (-2)^2 + 1 = 4 + 1 = 5

x = -1: y = (-1)^2 + 1 = 1 + 1 = 2

Do the same for x = 0, x = 1, x = 2

x     y

-2   5

-1    2

0    1

1     2

2    5

Part B

Look at points (-2, 5) and (-1, 2). The change in x from (-2, 5) to (-1, 2) is 1. The change in y is -3.

Now let's look at two other points which have a change in x of 1. Look at points (0, 1) and (1, 2). The change in x from (0, 1) to (1, 2) is 1. The change in y is 1.

You can see that for the first two points, a change of 1 in x produces a change of -3 in y, but for the second two points, the same change of 1 in x produce a change of 1 in y. Since the same change of x does not always produce the same change in y, the function is nonlinear.
