Answer: True
Step-by-step explanation:
Given: The ratio of the number of boys to the number of girls at Liam's school is 4:5.
There are 270 students at his school.
Then, Total boys = 
Total girls =
Clearly, (Number of girls) > (Number of boys)
Difference = (Total girls) - (Total boys)
= 150-120
= 30
So, Statement 3: "There are exactly 30 more girls than boys". is absolutely true.
Answer:
225 cm²
Step-by-step explanation:
dilatation factor = 3 , then
area factor = 3² = 9
the area of the dilated polygon is then 9 times the area of the original so
area of dilated polygon = 9 × 25 = 225 cm²
Step-by-step explanation:
I don't understand, why there is this segment about the 0 degrees Kelvin.
any material, water or the glass the water is in, or the air, or the floor or the wall : the higher the temperature (the scale does not matter, as long both temperatures use the same), the more energy it contains (the faster the particles in that substance are moving/vibrating).
therefore a glass of water with 80 degrees will have much more energy than one with 20 degrees.
the same way an aluminum can (the actual name of that material is aluminium, but Americans seemingly cannot pronounce that) with 30 degrees has more energy than one with 20 degrees.
