A ratio calculated in the analysis of financial statements shows the percentage increase from one year to another. restates all items on a financial statement in terms of dollars of the same purchasing power. expresses a mathematical relationship between two numbers. is meaningful only if the numerator is greater than the denominator.

expresses a mathematical relationship between two numbers

Step-by-step explanation:

A ratio is a quantitative relationship between the two numbers. Here quantitative means the number of the quantity which is counted. It represents the relation between the one number to the other number

Just take an example

The numerator is 6 and the denominator is 3

So the ratio would be 2:1

Hence, the third option is correct

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
