Cos pie divided by 12 in surd form
Answers
Answer:
¼(√6 + √2)
Step-by-step explanation:
We want to find cos (π/12) in surd form.
Now, cos (π/12) can be expressed as;
cos [(π/4) - (π/6)]
Now, from trig derivations we know that;
Cos (A - B) = CosACosB + sinAsinB
Thus;
cos [(π/4) - (π/6)] = cos(π/4)Cos(π/6) + sin(π/4)sin(π/6)
Now, in surd form;
cos(π/4) = sin(π/4) = (√2)/2
Cos(π/6) = (√3)/2
sin(π/6) = 1/2
Thus, Plugging in relevant values to get;
cos(π/4)Cos(π/6) + sin(π/4)sin(π/6) = ((√2)/2 × (√3)/2) + ((√2)/2 × 1/2)
This gives;
((√6)/4) + ((√2)/4) = ¼(√6 + √2)

Answer: Approximately 49 degrees
A slightly more accurate angle value is about 49.458398 degrees.
======================================================
Explanation:
Draw a right triangle as shown in the diagram below. The horizontal leg is 13 ft and the hypotenuse is 20 ft. The angle between these two sides is what we want to find.
With this reference angle, the adjacent side is 13 and the hypotenuse is 20. We use the cosine ratio to tie the sides together with this angle.
Let x be the unknown angle.
cos(angle) = adjacent/hypotenuse
cos(x) = 13/20
cos(x) = 0.65
x = arccos(0.65)
x = 49.4583981264954
x = 49
I'm rounding to the nearest whole number since the given values (13 and 20) are also whole numbers. If your teacher provides other rounding instructions, then be sure to follow that of course.
The angle of elevation is roughly 49 degrees. Make sure your calculator is in degree mode. The notation "arccos" stands for "arccosine" and it's the same as inverse sine.

Answers
Answer:
[tex]cos(a-b) = \frac{117}{125}[/tex]
Step-by-step explanation:
Explanation
Given that
[tex]sina = \frac{7}{25} , cos a = \frac{24}{25} , sinb =\frac{3}{5} and cosb =\frac{4}{5}[/tex]
Cos(a-b) = cosa cosb + sina sinb
[tex]cos(a-b) = \frac{24}{25} \frac{4}{5} +\frac{7}{25} \frac{3}{5}[/tex]
[tex]cos(a-b) = \frac{96}{125} +\frac{21}{125} = \frac{117}{125}[/tex]
Final answer:-
[tex]cos(a-b) = \frac{117}{125}[/tex]

O bicicleta costa 420 de lei. Pretul ei se reduce cu 15%. Cat va costa bicicleta dupa reducere.
Answers
Answer:
The price of the bicycle after the discount is 357 lei
Step-by-step explanation:
The given question says, "The bicycle costs 420 lei. Its price is reduced by 15%. How much will the bike cost after the discount."
Cost price of the bicycle = 420 lei
Discount = 15%
We need to find the price of the bicycle after the discount. It can be calculated as follows :
[tex]P=420\times \dfrac{15}{100}\\\\=63[/tex]
Price = 420 -63
= 357 lei
Hence, the price of the bicycle after the discount is 357 lei.

In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is Response area the value of the 9 in the hundredths place.
Answers
Answer:
the 9 in the tenths place is 10 times bigger than the one in the hundredths place
Step-by-step explanation:
The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.
What is the place value strategy?Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.
The decimal we are examining is 3.9928.
The 9 in tenth place has a value of 0.9.
The value of 9 in the hundredth place is 0.09
The fraction of the 9 in the tenth place is now the 9 in the hundredth place.
To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.
Mathematically, that would be;
0.09/0.9 = 0.1 = 1/10
This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place
So you can complete the statement by dragging and dropping "10 times" into the response area.

"My friend here Justin, he's already taken, and he's cracked at Fortnite my guy.
I've been contemplating this video a ton of late. I've been considering the video since it gives a provocative message and keen editorial about enslavement and fixation.
To start with, we should take this word by word. The initial segment of the primary sentence; the principal shimmer of gold, is "My friend here Justin" An everyday sentence from the outset, however kindly recollect what I said, to arrive at the pot of gold at the focal point of the cavern of incongruity is justified, despite any trouble. This little portion of the sentence addresses that the storyteller has a companion named Justin. The principal word is possessive; my, and companion here addresses the kid before the camera is indeed Justin, showed by the storyteller naming Justin just after saying companion here. How the storyteller we never see, and even the way that we never see the storyteller entreats us to embed ourselves into them.
"He's taken" This passage is clear as crystal, aside from one section. "He" shows the subject of the sentence; Justin, is "now" demonstrating that Justin has as of now and is "taken". The virtuoso of this sentence is unpretentious yet significant pleasantry in "taken", as in the old style utilization of this sentence it would imply that Justin is associated with a sentimental or sexual relationship.
"Also, he's cracked at Fortnite" the biggest portion, consequently the one generally stuffed with significance, this selection is the zenith of the multitude of different passages of the sentence. "Also, expands on the last selection demonstrating this is the continuation of the story, and "He's cracked at Fortnite" is the star proclamation of this extract.
In general, this show-stopper addresses the narrative of a man's compulsion breaking him while fusing the absolute best incongruity and pleasantry I've ever seen, all done in one video, eight seconds, one sentence, and fourteen words.

4X – 3y = 7
4x + y = 11
Answers
Answer:
(5/2 , 1)
Step-by-step explanation:
4X – 3y = 7
4x + y = 11
———————
Multiply a -1 to the bottom equation to get the 4x as a negative so it cancels out.
4x - 3y = 7
-4x - y = -11
——————
-4y = -4
Divide by -4
y = 1
Substitute the value of y into one of the equations and solve
4x - 3(1) = 7
4x -3 = 7
4x = 10
Divide by 4
X = 10/4
Simplify by dividing by 2
x = 5/2
Therefore the answer is (5/2, 1 )
