Find the volume of a right circular cone that has a height of 5.2 m and a base with a
radius of 15. 3 m. Round your answer to the nearest tenth of a cubie meter.

Answers

Answer:

1274.7 cubic meters

Step-by-step explanation:

Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.

How much Zn and how much HCl should be used to produce 1.5 g ZnCl2

Answers

Answer:

0.71963 g of Zn0.80256 g of HCl

Step-by-step explanation:

The required mass of reactants can be computed from the number of moles of product.

  moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles

Then the mass of Zn required is ...

  mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g

Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...

  mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g

_____

Comment

The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.

I believe, by process of elimination, it is "Kara's fee for the second child is $5"

Step-by-step explanation:

It can't be the second option because if her hourly rate for 2 kids was 14, then on hour 2 the total would be $28.

It can't be the third option because Jill's pattern is $11 dollars an hour, and Kara's is adding $9. So, by hour 4, Jill would make $44 and Kara would make $41.

Lastly, it can't be the 4th option because 11-9=2. 2 does not equal 3.

Place the following in order from least to greatest. 8,000,000 mm, 5 km, 7000,000 cm, 6,000 m

Answers

Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm

Step-by-step explanation:

Note that:

1km = 1,000,000mm

1m = 1000mm

1cm = 10mm

Therefore,

5 km = 5 × 1,000,000mm = 5,000,000mm

7000,000 cm = 7,000,000 × 10 = 70,000,000mm

6,000 m = 6000 × 1000 = 6,000,000mm

Therefore, from the least to the greatest will be:

5km, 6000m, 8,000,000 mm, 7000000 cm
