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.

What is the equation of the line perpendicular to 3x + y = -1 and passes through the point (-3,5)? Write your
sergij07 [2.7K]

Answer:

y = 1/3x + 6

Step-by-step explanation:

Rearrange equation to get y by itself.

3x + y = -1

y = -3x - 1

Perpendicular = opposite reciprocal. This means that the slope = 1/3

Convert to point-slope form: y - y1 = m (x - x1)

y - 5 = 1/3 (x - (-3))

y - 5 = 1/3 (x + 3)

y - 5 = 1/3x + 1

y = 1/3x + 6

Answer:

' =9 93/107 days

1 day= 107/1056

x = 1

x=1÷107/1056

1056÷107

=9 93/107 days

By the definition of complementary angles, since
svlad2 [7]

The blank spaces in the task content can be filled with; Substitution property, 90° and subtraction property.

<h3>What are the missing statements in the proof?</h3>

Since it follows from the vertical angles theorem that angle 1 = angle 4 as they are congruent.

Additionally, angles 1 and 2 are said to be complementary and hence, the sum of their measures is equal to 90°.

Finally, by virtue of the subtraction property of equality, the measure of angle 2 is; 90° - 40° = 50°.
