Answer:

13 lawns.

Step-by-step explanation:

To find out how many lawns Melinda has to mow, we need to find out how much money she earns per lawn. If we do 48/3, we get that for every lawn she mows, she earns 16 dollars. We then do 208/16 and we get that she has mow 13 lawns.

contractor wishes to build 9 houses, each different in design. In how many ways can he place these houses on a street if 6 lots
Tju [1.3M]

The houses can be placed in 362,880 ways.

<u>Step-by-step explanation:</u>

The 9 houses are each in different design.

The each lot can place any of the 9 houses.

  • The 1st lot can place anyone house of all the 9 houses.
  • The 2nd lot can place one of remaining 8 houses.
  • The 3rd lot can place one of remaining 7 houses.

Similarly, the process gets repeated until the last house is placed on a lot.

<u>From the above steps, it can be determined that :</u>

The number of ways to place the 9 houses in 9 lots = 9!

⇒ 9×8×7×6×5×4×3×2×1

⇒ 362880 ways.

Therefore, the houses can be placed in 362880 ways.

the volume of solid A is 28m3 and the volume of solid B is 1,792m3. If the solids are similar, what is the ratio of the surface
Maslowich
If k is the scale factor between the dimensions of the similar solids, the areas are related by k² and the volumes are related by k³. That is
\ \ \dfrac{V_{a}}{V_{b}}=k^{3}
\ \ k=(\dfrac{V_{a}}{V_{b}})^{\frac{1}{3}}

The areas are related by k², so
\ \ \dfrac{A_{a}}{A_{b}}=k^{2} = (\dfrac{V_{a}}{V_{b}})^{\frac{2}{3}}
\ \ \dfrac{A_{a}}{A_{b}} = (\dfrac{28\ m^{3}}{1792\ m^{3}})^{\frac{2}{3}}=(4^{-3})^{\frac{2}{3}}
\ \ =4^{-2}=\dfrac{1}{16}

The ratio of the surface area of solid A to that of solid B is ...

Solve a = 2x + 6xz for X
NeX [460]

Answer:

See below.

Step-by-step explanation:

So we have the equation:

a=2x+6xz

On the right, factor out an x:

a=x(2+6z)

Divide both sides by (2+6z). The right will cancel:

x=\frac{a}{2+6z}

And we're done!
