You would need to multiply 35 x .6 (which is 60%).
35 x .6 = 21, so at least 21 members need to be present to vote.

the formula to find the period of orbit a satellite around a planet is T^2=(4pi^2/GM)r^3 where r is the orbits mean radius. If y
Oxana [17]

Answer:

<u>The correct answer is r = ∛GM*T²/4π²</u>

Step-by-step explanation:

Let's rewrite the formula to find the period of orbit of a satellite around a planet, to solve for r, this way:

T^2=(4pi^2/GM)r^3

T² = (4π²/GM) * r³

r³ = T²/ (4π²/GM)

r³ = T² * GM/4π²

r³ = GMT²/4π²

∛r³ = ∛GM*T²/4π²

r = ∛GM*T²/4π²

<u>The correct answer is r = ∛GM*T²/4π²</u>

dezoksy [38]

Answer:

51.9

8.9

78.5

8.8

Explanation:

You round up if the number to the right is 5 or greater.

So, apply this to the numbers and the 8 in A rounds up, going to a 51.9.

The 9 does not round up because of the one.

The 5 also does not round up because of the 2.

The 7 does round up because of the 6.

the two triangles below are similar use what you know about similar triangles to find the missing side. show your work​
lara31 [8.8K]

If both triangles are similar the ratio of sides will be same

\\ \sf\longmapsto  \frac{x}{24} =  \frac{6}{12}   \\ \\ \sf\longmapsto 12x = 6 \times 24 \\ \\ \sf\longmapsto 12x = 144 \\ \\ \sf\longmapsto x =  \frac{144}{12}  \\ \\ \sf\longmapsto x = 12

A wall that is 10 feet high and 20 feet long contains one ton of bricks. How many tons should be purchased to brick a wall that
vitfil [10]

Answer:

9 tons

Step-by-step explanation:

So first we have to figure out the area of the smaller wall. We know it is 10 feet high and 20 feet long, so we multiply the length and width together to get 200 square feet, and that equals 1 ton. Now if we take the 1800 square foot wall and divide it by the smaller wall, we get 9. This is because the larger wall is 9 times the size of the smaller wall. So if the smaller wall needs 1 ton, and the larger would need 9 times the amount, we would need 9 tons.
