A company that makes hair-care products had 9 comma 000 people try a new shampoo. Of the 9 comma 000 people, 72 had a mild allergic reaction. What percent of the people had a mild allergic reaction?

The percent of people with mild allergic reaction is 0.8%

Step-by-step explanation:

The company has 9000 people, and 72 people have mild allergic reaction.

The fraction of people with mild reaction is 72 over 9000, i.e. 72/9000

72 and 9000 are multiple of 9, therefore reducing both by 9, we will have 8/1000.

8 and 1000 are both multiple of 4, so we will reduce both by 4, we will have

2/250.

2/250 can still be reduced by to, therefore we will have 1/125

To get the percentage, we will now multiply the fraction 1/125 by 100, we will have 100/125

Reduce both 100 and 125 by 25 which will make 4/5

then, turning 4/5 to decimal, we will have 0.8%

Therefore 0.8% of people had a mild allergic reaction

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
