Answer:

A) This is a self-interest study.

Step-by-step explanation:

Given is that a shampoo company recently paid a consulting firm to produce a study to determine if using their product resulted in cleaner hair than other brands.

We can see that this study is based on the self interest of the shampoo company.

Therefore, the thing wrong with this study is that it is a self-interest study.

The sum of a number times 8 and 21 is less than -16.
vodka [1.7K]

Hello.

First of all, let the number be t.

8 times t can be written like this:

\mathrm{8t}

Notice that the number is before the variable and the times sign (×) is not there.

We can write it as 8×t, but we usually write it as 8t.

The sum of means we add:

8t+21

Now, "less than" is "<" :

\mathrm{8t+21 < -16}

Therefore, the answer is

\mathrm{8t+21 < -16}

I hope it helps.

Have a nice day.

The rectangular ground floor of a building has a perimeter of 780 ft. The length is 200 ft more than the width. Find the length
ivolga24 [154]

Answer:

L = 295ft

W = 95ft

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

If the length is 200 ft more than the width, then:

L = 200+W

Substitute

P = 2(200+W+W)

780 = 2(200+2W)

780 = 400+4W

4W = 780-400

4w = 380

W = 380/4

W = 95ft

Since L = 200+w

L = 200+95

L = 295ft
