A pack of gum is in the shape of a rectangle prism with a length of 8 centimeters and width of 2 centimeters. The volume of the
victus00 [196]
Hello!

We know that the length of the pack is 8 cm, width is 2 cm, and the volume is 48 cm^3.

The formula for volume is:

V = l × w × h

We don't want to find the volume...we already have that!

But we can use the volume and the length and width to find the height.

Since we multiply the dimensions to find the volume, we'll have to do the opposite to find a dimension.

And what's the opposite of multiplication? Division!

H = V ÷ lw

Multiply the length by the width, then divide the volume by that.

H = 48 ÷ 8(2)

H = 48 ÷ 16

H = 3

We can double check by using this to find the volume.

V = 8 × 2 × 3

V = 48

This means we're right!

ANSWER:

The height of the pack of gum is 3 centimetres.

The measure of M is 57 begat is the measure of its complementary angle ?
8_murik_8 [283]

Answer:

33°

Step-by-step explanation:

Complementary angles add up to 90°

If we set the other angle as ∠K,

m∠M + m∠K = 90°

57° + m∠K = 90°

m∠K = 33°

Thus, the other angle would be 33°

Gravel is being dumped from a conveyor belt at a rate of 35 ft3/min, and its coarseness is such that it forms a pile in the shap
Mazyrski [523]

Answer:

  dh/dt ≈ 0.55 ft/min

Step-by-step explanation:

The volume is given by the formula ...

  V = (1/3)πr²h

We have r = h/2, so the volume as a function of height is ...

  V = (1/3)π(h/2)²h = (π/12)h³

Then the rates of change are related by ...

  dV/dt = (π/4)h²·dh/dt

  dh/dt = (4·dV/dt)/(πh²) = 4(35 ft³/min)/(π(9 ft)²)

  dh/dt ≈ 0.55 ft/min

Answer to the question
oee [108]

Answer:

<h3>x = 4</h3>

Step-by-step explanation:

102 + 102 + 24x + 24x - 18 - 18 = 360

204 + 48x - 36 = 360

204 + 48x = 360 + 36

204 + 48x = 396

48x = 396 - 204

48x = 192

x = 192/48

x = 4
