As per the problem

The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.

we have been asked to find

Which ratio shows the number of chlorine tablets needed for 42 days?

Since for each 14 days the number of tablets required is 5

So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.

So When number of days=14*3=42\\

Then the number of tablets required for 42 days is =5*3=15\\

By decreasing each dimension by 2 units, the area of a rectangle decreased from 40 square feet (on the left) to 16 square feet (
goldenfox [79]

Answer:

60%

Step-by-step explanation:

40 ft² is 100%

so, 1% = 0.40 ft²

now we need to ask, how often did 1% fit into the 16 ft².

that means

16 / 0.4 = 16 / (4/10) = (16×10)/4 = 160/4 = 40 %

so, the new, smaller area is only 40% of the original area.

and that means, that the area decreased by 100-40 = 60%

Maru [420]

Answer:\frac{85}{81}

To find the slope of a line, you would use \frac{y_{2} -y_{1} }{x_{2}-x_{1}  }.

We use out coordinates to plug into this equation.

\frac{84-(-1)}{98-17} =\frac{85}{81}

Total = 630

Spring = 441

Required

Determine the ratio of lawns in spring to total

Ratio = Spring:Total

Ratio = 441 : 630

Convert to fraction

Ratio = \frac{441}{630}

Ratio = 0.7
