Exponential growth have the same second difference in each terms, unlike a linear growth the first difference is the same. In this problem the 2nd difference common to them is 5.

month #1

80

month # 2

80 + 20= 100

Month #3

100 25=125

month #4

125+30=155

month #5

155+35=185

month#6

185+40=225

month #7

225+45=315

month #78

315 + 50 =365

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. Sta
amid [387]

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 = \dfrac{4}{4+5}\times270=\dfrac{4}{9}\times270=120

Total girls =\dfrac{5}{4+5}\times270=\dfrac{5}{9}\times270=150

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.

weqwewe [10]

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

Pleas answer quickly
alexandr1967 [171]

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.
