Answer:

56 gray chairs

24 blue chairs

Step-by-step explanation:

ratio of gray to blue chairs in each row

Gray : blue = 7 : 3

Gray chairs = 7

Blue chairs = 3

Total ratio = 7 + 3

= 10

how many gray chairs and blue chairs will julio use if he sets up a total of 80 chairs

Number of gray chairs = 7/10 × 80

= 0.07 × 80

= 56 gray chairs

Number of blue chairs = 3/10 × 80

= 0.03 × 80

= 24 blue chairs

56 gray chairs

24 blue chairs

Tan 1.1 – tan 4.6/
VladimirAG [237]

The value of the given equation is –0.37458.

Solution:

Given equation is:

$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}

Let us first find the values.

The value of tan 1.1 = 1.96475

The value of tan 4.6 = 8.86017

Substitute these values in the given equation.

$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}

            $=\frac{1.96475-8.86017}{1+1.96475 \times 8.86017}

            $=\frac{-6.89542}{1+17.4080}

            $=\frac{-6.89542}{18.4080}

            = –0.37458

$\frac{\tan 1.1-\tan 4.6}{1+\tan 1.1 \tan 4.6}=-0.37458

Hence the value of the given equation is –0.37458.
