Answer:
37.38
Step-by-step explanation:
Remark
The ratio tells you how they are divided between night and day.
In other words night/ day = 19/32
That's not what you want.
What you want is night over total.
Total
Total = night + day = 19.1 + 32 = 51.1
Night Percent
Night% = Night * 100 / Total
Night% = 19.1 * 100 / 32
Night% = 37.38 %
Answer:
x < 2
Step-by-step explanation:
If 2x + 3 is less than 7, then 2x alone must be less than 4.
2x + 3 < 7
2x < 4
If 2x is less than 4, then x must be less than 2.
2x < 4
x < 2
Answer:
6,750,000 cm³ = 6.75 m³
Step-by-step explanation:
a scale version means that the ratio of every dimension of scale vs. real object is 1/50.
volume is created by multiplying 3 dimensions.
so, going from scaling to real the volume has to be multiplied by 50×50×50 = 50³ = 125000
so, as for the scale model we needed 54 cm³, for the full size object we need 54×125000 = 6,750,000 cm³ of metal.
or to bring it to m³ (1m³ = 100×100×100 cm = 1000000 cm³)
that would be 6.75 m³ of metal.
