One of the students wanted to know the material in the four propeller
Lyrx [107]

The material is made of carbon composite since the density of this material is similar to the drone

<h3>What is density?</h3>

Density is mass per unit volume. It is is an important property of a material that helps in saying other features of the material. It also says substance that has more weight as a highly dense substance will have more weight when compared with a less dense substance.

<u>Given data</u>

Initial volume of water = 1000ml

the drone displaced the water to 2290 ml

mass of the drone = 2 kg = 2000 g

<h3>Density of the drone</h3>

volume of the drone equals the volume of water displaced

2290 ml - 1000 ml = 1290 ml

density in g/cm*3

= mass / volume

= 2000 / 1290

= 1.550 g/ml

The density of the drone is similar to density of carbon composite hence the drone of made of carbon composite

Daniel and Sofia both solve this system of equations: y = -1.5x + 5.7 y = 0.5x + 0.3 Daniel's solution is (1.1, 2.4). Sofia's so
scoundrel [369]
Y = -1.5x + 5.7
y = 0.5x + 0.3

-1.5x + 5.7 = 0.5x + 0.3
-1.5x - 0.5x = 0.3 - 5.7
-2x = - 5.4
x = -5.4/-2
x = 2.7

y = 0.5x + 0.3
y = 0.5(2.7) + 0.3
y = 1.35 + 0.3
y = 1.65

solution is (2.7, 1.65)

Sophia is more likely to be correct because the x coordinate is between 2 and 3 and the y coordinate is in between 1 and 2
