10x - 4 = 16 What does x equal to?

Mathematics
1 answer:
Dennis_Churaev [7]3 years ago
5 0

Answer:

x = 2

Step-by-step explanation:

First isolate the variable:

10x - 4 = 16

      +4   +4

10x = 20

Then get x by itself:

10x = 20

x = 20/10

x = 10

Volume equation-6th grade
ivann1987 [24]
Volume is measured units Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches or 64 cubic inches.

Use differentials to estimate the amount of material in a closed cylindrical can that is 4040 cm high and 1616 cm in diameter if
uranmaximum [27]

Answer:

The volume of the metal which make up the can = 179.95 cm^3

Step-by-step explanation:

To solve this the can height = 40 cm

The diameter of the can = 16 cm

The thickness of the top of the can = 0.2 cm

The thickness of the sides = 0.05 cm

The outer volume of the cylinder = pi × r^2 × h = pi × (16/2)^2 × 40 = 8042.5 cm^3

However, the cylinder is 0.2 cm thick on top and 0.05 cm thick on the sides hence

Change in volume dV is given by partial differentiation dV/dr = 2×pi×r×h and dV/dh = 2×pi×r^2×dh

Therefore, dV = dr×2×pi×r×h1 + dh×2×pi×r^2 as V is a function of both h and r

Where h1 = the height of cylinder - top of cylinder = 40-0.2×2 = 39.6 cm

Then we have

dV = 0.05×2×pi×8×39.6 + 0.2×2×pi×8^2 = 99.53 cm^3 + 80.42 cm^3 = 179.95 cm^3

Hence the volume of the metal which make up the can = 179.95 cm^3
