The proportion of dissolved substances in seawater is expressed as 0/00, which is the same as parts per hundred.
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
We apply the concepts of ratio and proportion every day, for example, while dealing with money in business or when preparing any meal, etc. Students occasionally struggle to understand the difference between ratio and proportion. With numerous examples and problems that have been solved, this article helps students understand these two ideas clearly.

Answer:
1. y=6x-22
Step-by-step explanation:
point-slope form equation : y=mx+b
1. (3, -4) m=6
Sub the numbers is
y=-4 / x=3 / m = 6
-4=6*3+b
-4=18+b
b=-22
So your equation would be y=6x-22
2. (4, 2) m=-5/3
sub the numbers into the equation
y=2 / x=4 / m= 5/3
2=4*5/3+b
2=20/3+b
b=8 2/3
so the equation would be
y=-5/3x+8 2/3
3. (0,2) m=4/5
sub the numbers into the equation
2=0*4/5+b
b=2
so the equation would be
y=4/5x+2
4. (-2, -7) -3/2
sub the numbers into the equation
-7=-3/2*-2+b
b=-10
so the equation would be
y= 3/2x-10
5. (4,0) 1
sub the numbers into the equation
0=1*4+b
b=-4
so the equation would be
y=x-4
6. (5,-8) -3
sub the numbers into the equation
-8=5*-3+b
-8=-15+b
b=7
so the equation would be
y=-3x+7
7. (-5, 2) 0
sub the numbers into the equation
2=-5*0+b
b=2
so the equation would be
y=2
8. (1, -8) -1/5
sub the numbers in
-8=1*-1/5+b
b= 7 3/5
so the equation would be
y=-1/5x + 7 3/5
9. (-6,1) 2/3
sub the number in
1=2/3*6+b
b=-3
so the equation would be
y=2/3x-3
Answer: 5w^2 (15w ^3 -7)
Good luck !
Point S makes the two connected angles the same. They both have right angles.
And one side of each is congruent.
This means you know 2 angles are the same and one side is the same.
You would use ASA (Angle, Side, Angle)
