The octane rating of gasoline is the percentage of isooctane in the fuel. For example, 89-octane gasoline contains 89% of isooctane. How many liters of 88-octane gasoline should be mixed with 100 liters of 95-octane gasoline to get a mixture which is 93-octane gasoline ?

40 liters of 88-octane gasoline should be mixed

Step-by-step explanation:

Here in this question, we are interested in calculating the number of liters of 88-octane gasoline that should be mixed with 100 liters of 95-octane gasoline to get a mixture of 93-octane gasoline.

Since we do not know the number of liters, we can represent it by x

This means that the total number of liters of the 93-octane gasoline we are looking at producing is (100 + x) liters.

Thus, if we multiply the number of liters of each gasoline type by their isooctane content and add together, we will obtain the product;

Hence;

88(x) + 100(95) = 93(100 + x)

88x + 9500 = 9300 + 93x

93x -88x = 9500-9300

5x = 200

x = 200/50

x = 40 liters

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
