Answer:
Mass of the liquid in the tank will be 
Step-by-step explanation:
We have given volume of tar 
1 gallon = 3.785 liter
So 
Specific gravity = 1.2
Density of water 
We know that specific gravity 

Density of liquid 
So mass of liquid = volume × density
= 
So mass of the liquid in the tank will be 
Given:
BD is parallel to XY.
One of the angle is 85°
To find:
The value of y.
Solution:
Parallel lines BD and XY cut by a transversal line.
Angle y and 85° are alternate interior angles.
Alternate interior angle theorem:
If two parallel lines are cut by a transversal line, then the pairs of alternate interior angles are congruent.
⇒ y = 85°
The value of y is 85.
A. Their signs are the same.
b. one is negative, the other is positive
Answer:
x = 6
Step-by-step explanation:
4x - 3 = 7×3
4x - 3 = 21
4x = 21 + 3
4x = 24
x = 6
I hope you understood the explanation!
