A company that makes? hair-care products had 7000 people try a new shampoo. Of the 7000 ?people, 42 had a mild allergic reaction

hram777 [196]

Answer: Percent of people who had a mild allergic is 0.6%.

Step-by-step explanation:

Since we have given that

Total number of people try a new shampoo = 7000

Number of people had a mild allergic reaction = 42

We need to find the "Percentage of people had a mild allergic":

Percentage of people had a mild allergic is given by

$\frac{\text{ Total number of people who had a mild allergic}}{\text{ Total number of people}}\times 100\\\\=\frac{42}{7000}\times 100\\\\=\frac{42}{70}\\\\=0.6\%$

Hence, Percent of people who had a mild allergic is 0.6%.

4. A sports car accelerates from rest to a final velocity of 64 m/s at a rate of 12.3

Ivanshal [37]

Answer:

$t = 5.2\ s$

Step-by-step explanation:

Given

$a= 12.3m/s^2$ --- acceleration

$v = 64m/s$ --- final velocity

$u =0m/s$ --- initial velocity (it is 0, because the car starts from rest)

Required

Determine the time taken

This will be solved using Newton's first equation of motion:

$v = u + at$

Substitute values for v, u and a

$64 = 0 + 12.3*t$

$64 = 12.3t$

$12.3t = 64$

Make t the subject

$t = \frac{64}{12.3}$

$t = 5.2\ s$

<em>Hence, the time taken is approximately 5.2 seconds</em>
