Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.
Answer:
16.875 spiders
Step-by-step explanation:
Given
Let
So, we have:
--- equal amounts
--- the legs
Required
The number of spider
Since she has an equal amount of B, C and S;
The expression can be written as:
Solve for S
<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>
the answer in the attached figure
Nearly 81 moons will be required to equate the mass of moon to the mass of earth.
Step-by-step explanation:
Mass of earth is 5.972*10^24 kg.
Mass of the moon is 7.36*10^25 g = 7.36*10^22 kg
As mass of the Earth is given as 5.972 * 10^24 kg and mass of the moon is given as 7.36 * 10^22 kg, then the number of moons required to make it equal to the mass of earth can be calculated by taking the ratio of mass of earth to moon.
Mass of Earth = Number of moons * Mass of Moon
Number of Moons = Mass of Earth/Mass of moon
Number of moons = 5.972 * 10^24/7.36*10^22= 81 moons.
So nearly 81 moons will be required to equate the mass of moon to the mass of earth.
X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
