Answer:
35
Step-by-step explanation:
5+(5)(6)
=5+30
=35
The density of the liquid will be 1500 kg per cubic meter.
The density is the ratio of mass to volume of any substance.
Let m be the mass of the object and v be the volume of the object.
Then the density D will be
D = m / v kg / cubic m
More the density means the number of the molecules will be more in a unit volume.
A sample of liquid has a mass of 24g and a volume of 16ml.
We know that one kg equals to 1000 grams.
24 g = 0.024 kg
We know that one ml equal to 10⁻⁶ cubic meters.
16 ml = 16 × 10⁻⁶ cubic meters
Then the density of the liquid will be
Density = 0.024 / 16 × 10⁻⁶
Density = 1500 kg per cubic meter
Thus, the density of the liquid will be 1500 kg per cubic meter.

Answer:
d b f
Step-by-step explanation:
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Requiredpercentage value = a
total value = b
Percentage = a/b x 100
Percentagechange = [ Change in the amount / Initial amont ] x 100
The percent of change is 66.7%.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Requiredpercentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The Initialnumber of people = 75
The finalnumber of people = 25
The change in the number of people = 75 - 25 = 50
The percentagechange.
= 50/75 x 100
= 2/3 x 100
= 66.7 %
Thus,
The percent of change is 66.7%.
