The ratio is 2:3 so... the total of them is 5
25/5=5 Therefore we can multiply 5x2 and 5x3
The new ratio is 10:15
Since the ratio is hot lunch:a la carte, The 10 is the amount of hot lunches expected and 15 is amount of students expected to eat a la carte
So 10 students eat hot lunch
15 students eat a la carte
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

Answer: The proof is mentioned below.
Step-by-step explanation:
Here, Given : m∠AOC = 160° m∠AOD= (3x-10)° and m∠ DOC= (x+14)°
Prove: x= 39°
Statement Reason
1. m∠AOC = 160°, m∠AOD= (3x-10)° 1. Given
and m∠ DOC= (x+14)°
2. m∠AOD+m∠DOC=m∠AOC 2. Because OD divides ∠AOC
into ∠AOD and ∠DOC
3. (3x-10)° +(x+14)°= 160° 3. By substitution
4. 4x+4 = 160° 4. By equating like terms
5. 4x= 156° 5. By subtraction property
of equality
6. x= 39° 6. By division property of equality
8 can go into 270 evenly.....90 times to be exact so the answer is 90
