Mathematics
1 answer:
choli [55]4 years ago
6 0

Answer:

50

Step-by-step explanation:For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = . Example 1 : If y varies inversely as x , and y = 6 w

To 1 significant digit, how much Coumarin (in grams) would a 70 kg (154lb) student have to ingest to reach the LD50?
timofeeve [1]

Answer:

2 × 10 g

Step-by-step explanation:

The lethal dose 50 (LD50) of Coumarin is 293 mg/kg body mass. The amount of Coumarin that a 70 kg student would have to ingest to reach the LD50 is:

70 kg body mass × (293 mg/kg body mass) = 20510 mg

1 gram is equal to 1000 milligrams. The mass (in grams) corresponding to 20510 milligrams is:

20510 mg × (1 g/ 1000 mg) = 20.51 g ≈ 2 × 10 g

The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the
Juli2301 [7.4K]

Answer:

706.3 cm³

Step-by-step explanation:

<u>Given</u>

<em>"The cone and cylinder above have the same radius and height..."</em>

<em>the volume of the cone = 210 cubic centimeters</em>

<u>Formula</u>

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

<u>How to solve</u>

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )
