Answer: equation

Reasoning: So an easy way to remember this is, an equation has an equals sign. So remember equal sounds like equation so that’s a way to know. And an expression doesn’t have an equals sign.

If the speed of a car is 20 m s^-1 then what is its speed in km h^-1 ?<br>#no spam​
ivanzaharov [21]
  • Speed in m/s=20m/s

We have to convert it to km/h

\\ \sf\longmapsto 20\times \dfrac{3600}{1000}

\\ \sf\longmapsto 20\times \dfrac{18}{5}

\\ \sf\longmapsto 4times 18

\\ \sf\longmapsto 72km/h

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them.
snow_lady [41]

Answer:

d = 1.46 m

Step-by-step explanation:

We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:

From the question given above,

F is inversely proportional to square of d. This can be written as:

F ∝ 1/d²

F = K/d²

Cross multiply

K = Fd²

But:

Force (F) = 0.006 N

Distance (d) = 4 m

Constant (K) =?

K = Fd²

K = 0.006 × 4²

K = 0.006 × 16

K = 0.096 Nm²

Therefore, the relationship between the force (F) and the distance (d) is:

F = K/d²

F = 0.096 / d²

Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:

Force (F) = 0.045 N

Constant (K) = 0.096 Nm²

Distance (d) =?

F = K/d²

0.045 = 0.096 / d²

Cross multiply

0.045 × d² = 0.096

Divide both side by 0.045

d² = 0.096 / 0.045

Take the square root of both side.

d = √(0.096 / 0.045)

d = 1.46 m.

PLS HELP ME ASAP WITH THIS! (LOTS OF POINTS!) (show work OR explain)
riadik2000 [5.3K]
So they tell you to let x represent the cost of Deandra's sofa. So since Selena's sofa costs 30 dollars LESS than HALF the cost of Deandra's, we know we have to divide by 2 and subtract 30. 
The equation would be x/2-30. (B)
