A company that makes​ hair-care products had 400 people try a new shampoo. Of the 400 people, 16 had a mild allergic reaction. What percent of the people had a mild allergic​ reaction?

Answers

Answer 1

Answer:

4% of people had a mild allergic reaction

Step-by-step explanation:

16 is 4% of 400

[tex]y = p\% \times x[/tex]

[tex]p\% = y \div x[/tex]

[tex]p\% = 16 \div 400[/tex]

[tex]p = 0.04[/tex]

Convert decimal to percentage

[tex]p\% = 0.04 \times 100 = 4\%[/tex]

Answer 2

My Answer:

I am pretty sure it would be around 4%

Answer:

It's Halloweeeeen

Step-by-step explanation:

(I took Geometry before and I still have my notes). To find the area of the rectangle, you'd multiply 12 x 9 because the rEcIpE for it is length x width (A=lw). Whe you do that, you get 108.

To find the area of the triangle, you have to multiply the base and the height, then divide that by 2. The recipe for that is 1/2 base x height (A=1/2bh). The base of the triangle is equal to the height of the rectangle (which is 9). So you'd be multiplying 9x7 which equals 63, then dividing that by 2 which is 31.5.

After all that, you add 108 and 31.5 to get 139.5cm squared! Hope this helped :3

Answer:

The salesman sold 120 kg of pears in the morning and 240 kg of pears in the afternoon.

Step-by-step explanation:

Let x be the amount of pears sold in the morning.

2x, amount of pears sold in the afternoon.

x + 2x = 360 kg

Solution:

x + 2x = 360 kg

3x = 360 kg

3x/3 = 360 kg/3

x = 120

He sold 120 kg of pears in the morning.

2x = 2(120 kg) = 240 kg

He sold 240 kg of pears in the afternoon.

Final Answer:

The salesman sold 120 kg of pears in the morning and 240 kg of pears in the afternoon.
