Solving inequalities, what is x/18>27
Lunna [17]

Answer:   x > 486

Explanation:

We have some number x and we divide that by 18. The result is larger than 27. To find possible values for x, we need to undo what is happening to x. The opposite of division is multiplication. We multiply both sides by 18 to cancel out the "18" on the left side, which will isolate x to get it to its own side.

This is what the steps look like

x/18 > 27

18*( x/18 ) > 18*27 .... multiplying both sides by 18

x > 486 ... note the 18's cancel on the left side

So this means x is some number greater than 486.

g If a snowball melts so that its surface area decreases at a rate of 4 cm2/min, find the rate (in cm/min) at which the diameter
maks197457 [2]

Answer:

Rate of change of the diameter is equal to 0.053cm/min

Step-by-step explanation:

A snowball is of the shape of a sphere

Surface area of Sphere (S)= 4*pi*R^2

Rate of change of surface area

dS/dt = -4cm^2/min

the negative sign indicates the surface area is decreasing.

Radius = d/2 where d represents diameter

using this is the surface area equation

S = 4*pi*(d/2)^2

   = pi*d^2

dS/dt = 2*pi*d*d(d)/dt

4 = 2*pi*d*(d)/dt

d(d)/dt = 2/12*pi= \frac{1}{6pi} cm/min

so the rate of change of the diameter is equal to 0.053cm/min

25 * 7 = 175

175 * 6 = 1050

2. Answer:

C. 8

Step-by-step explanation:

To find the missing dimension of a rectangle, you can easily just divide the total by each dimension

540 divided by 7.5 = 72

72 divided by 9 = 8
