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.

How do I solve for question number 6

Natali5045456 [20]

Answer:

$18 + 18\sqrt{3}$

Step-by-step explanation:

The rectangle has been split into two right triangles. The hypotenuse of the triangle (the diagonal) is 18. The angle in the triangle is 30. All right triangles have unique relationships between their sides depending on the angles. This triangle must be a 30 - 60 - 90 triangle and its sides will be a scaled version of $1 - \sqrt{3} -2$ .

The side 2 correspond to the hypotenuse of length 18. 2*9 = 18 and so the scale factor is 9. To find the remaining sides, multiply each side length by 9 from $1 - \sqrt{3} -2$ .

It becomes $9 - 9\sqrt{3}-18$ . So the rectangle is 9 by $9\sqrt{3}$ .

The perimeter of the rectangle is $9 + 9 + 9\sqrt{3} + 9\sqrt{3}=18 + 18\sqrt{3}$

Nina wants to buy a bicycle thats costs $150. she has saved 6 percent of the total cost of the bicycle.how much money has nina s

notka56 [123]

The understanding one needs to work with percentages is:
1/100 = 1% = 0.01
Also
6/100 = 6% = 0.06
also
25/100=1/4=0.25=25%

To find a spesific share of a total, we can multiply the perectage with the total, like this: Total * 6% or in a way easier to work with: Total * 0.06 or (Total * 6)/100

If you have a calculator i would recommend using the decimals, as they are one of the easiest to type in - and remember once you get the hang of it.

To find the money Nina has saved, you do the following.
150*0.06=9$
Nina has saved 9 dollars.

The remaining percent she needs, is
100-6=94%

She still needs money for 94% of the bike.
