Answer: Im not giving answer to that but i will do this one

A water tank holds 256 gallons but is leaking at the rate of 3 gallons per week. A second water tank holds 384 gallons and is leaking at a rate of 5 gallons per week.After how many weeks will the amount of water in the two tanks be the same.

Step-by-step explanation:

you have: one is leaking 3 gallons per week and holds 256 gallons; whereas, the other one is leaking 5 gallons per week and holds 384 gallons.

Set up both the equations....

In y=mx+b form--->>>

y=-3x+256

y=-5x+384

To figure out when they will be equal..set the equations equal to each other....(remember to isolate the variable)

-3x+256=-5x+384

-3x+256=-5x+384

     -256        -256

-3x=-5x+128

-3x=-5x+128

+5x+5x

2x=128

x=64

After 64 weeks the amount of water in both tanks will be the same.

Thus, your answer.

Find the series in which<br>5th term is 22/16 and 4th term is -4​
Gala2k [10]

Answer:

The series is given as follows;

-\dfrac{161}{8} , \ -\dfrac{59}{4} , \ -\dfrac{75}{8}, \ -4, \ \dfrac{22}{16} ......

Step-by-step explanation:

Assuming the series is an arithmetic progression, (AP), series, we have

The nth term of the desired series = a + (n - 1)×d

Where;

a = The first term

n = The position of the term in the series

d = The common difference

Given that the 5th term = 22/16 and the 4th term = -4, we have;

d = The difference between consecutive terms = Difference between the 5th term and the 4th term

∴ d = 22/16 - (-4) = 43/8 = 5.375

22/16 = a + (5 - 1)×5.375

∴ a = 22/16 - 4×5.375 = -20.625

The series is therefore;

-\dfrac{161}{8} , \ -\dfrac{59}{4} , \ -\dfrac{75}{8}, \ -4, \ \dfrac{22}{16} ......

monitta

Answer

Find out the  what is the constant proportionality .

To prove

Formula

Area of rectangle = Length × Breadth

As given

Marielle’s painting has the dimensions shown (Painting Width = 18 inches, Painting Length = 24 inches).

Area of the original painting = 18 × 24

                                              =  432 inches²

As given

The school asks her to paint a larger version that will hang in the cafeteria.

The larger version will be twice the width and twice the height.

Length of the  larger version painting = 2 × 18

                                                              = 36 inches

Breadth of the  larger version painting = 2 × 24

                                                                = 48 inches

Now area of the larger version painting = 36 × 48

                                                                  = 1728 inches²

As given

The  area of the original painting proportional to the area of the larger

painting .

Thus

Area\ of\ original\ painting\ \propto\ Area\ of\ larger\ painting

Area\ of\ original\ painting\ = k\times \ Area\ of\ larger\ painting

Where k is the constant  of proportionality

Putting the value

432 = k × 1728

k = \frac{1728}{432}

k = 4

The constant proportionality is 4 .

Hence proved

Subtract.<br><br> Eight-ninths minus one-third
Bingel [31]

8/9 - 1/3

To subtract these two fractions, first find a common denominator.

The common denominator will be the

least common multiple for the two denominators.

In this case, the least common multiple of 9 and 3 is 9.

So to subtract, a denominator of 9 is needed in each fraction.

8/9 already has 9 in the denominator so it stays the same.

To get a 9 in the denominator of 1/3, multiply top and bottom by 3.

This gives us 3/9.

So we have 8/9 - 3/9 which is 5/9.
