There are 9 × 10^5 grains of rice in the container.

Step-by-step explanation:

  • Step 1: Find the mass of rice in the container.

Mass of empty container = 0.6 kg

Mass of container filled with rice = 18.6 kg

⇒ Mass of rice = 18.6 - 0.6 = 18 kg

  • Step 2: Find the number of grains in the container.

Mass of one grain of rice = 2 × 10^-2 g = 2 × 10^-2/10³ kg (∵ 1 kg = 1000 g)

                                          = 2 × 10^-5 kg

⇒ Number of grains of rice = Total Mass of rice/Mass of 1 grain

                                             = 18/2 × 10^-5

                                             = 9 × 10^5 grains of rice

If the volume of a cube is27cm2,find its total surface area
kumpel [21]

Volume of a cube is s³

Total surface Area of a cube is 6s².

Therefore, given a volume of 27cm³

s³=27,

s=3√27

s=3cm.

Total surface Area

A=6s²

A=6×(3×3)

A=6×9

A=54cm².

Answer:

The answer to your question is:

Step-by-step explanation:

1.-

  y = 84°

  5x - 61 = 84

  5x = 84 + 61

   5x = 145

  x = 29

2.-

  m∠1 + m∠6 = 180   they are supplementary angles

  ∠1 = 180 - 143

 ∠1 = 37

 ∠1 = ∠ 3 because are vertical angles.

3.-

m∠2 + m∠5 = 180    they are supplementary angles

∠2 + 79 = 180

∠2 = 180 - 79

∠2 = 101

m∠3 = m∠5   they are alternate angles

△ ABC and △ DEF are similar triangles. If m∠ A =102° and m∠ E = 46° , what is the m∠ C ?
Ivahew [28]
It’s 32 because you add 102+46=148 and then you have to have 180 so 180-148=32 so your answer is 32.
