7.1 and 7.5 because any integer is a rational number
The density of the liquid is 1.55 g/mL.
Given the following data:
Mass of liquid = 22.8 grams
Volume of liquid = 14.7 mL
To find the density (unknown) of the liquid:
Density is mass all over the volume of a substance or an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;
Substituting the values into the formula, we have;
Density = 1.55 g/mL
Therefore, the density of the liquid is 1.55 g/mL.

Answer: 22.5 degrees
Step-by-Step Explanation:
As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.
=> All the angles sum up to 180.
Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5
Therefore, x = 22.5 degrees
Verification:
=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS
