Answer: the percent decrease in accidents is 70%

Step-by-step explanation:

If a manufacturer reduces the number of in the job accidents from an average of 20 a month to an average of 6 a month, it means that the amount by which the number of in the job accidents reduced is

The ratio of yellow marbles to purple marbles was 13 to 4. If there was 102 marbles in the bag, how many were yellow marbles?
Pani-rosa [81]

The total number of yellow marbles in the bag was 78 marbles

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The ratio of yellow marbles to purple marbles in the bag = 13 : 4

Let the total number of yellow marbles in the bag be = 13x

Let the total number of purple marbles in the bag be = 4x

Now , the equation will be

The total number of marbles in the bag = 102

So , substituting the values in the equation , we get

The total number of marbles in the bag = total number of yellow marbles + total number of purple marbles

The total number of marbles in the bag = 13x + 4x

13x + 4x = 102

17x = 102

Divide by 17 on both sides of the equation , we get

x = 6

Therefore , substituting the value of x in the above expressions , we get

Total number of yellow marbles in the bag = 13x

Total number of yellow marbles in the bag = 13 x 6

Total number of yellow marbles in the bag = 78 marbles

And ,

Total number of purple marbles in the bag = 4x

Total number of purple marbles in the bag = 4 x 6

Total number of purple marbles in the bag = 24 marbles

Hence , The total number of yellow marbles in the bag was 78 marbles
