Answer:
I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."
Answer:
the blue sky is caused by sunlight reaching earth atmosphere which is scattered by the gases and air particles. which blue light is scattered more so that is why the sky is blue

The solution is, the simplified value of the expression is, 1.
To simplify the expression, we need the trigonometric identities given:
we know that,
1. cot=1/tan
2. tan=sin/cos
3. sec=1/cos
so, we have,
cot θ sec θ sin θ = 1/tanθ(1/cosθ)sinθ
= (1/(sinθ/cosθ))(1/cosθ)sinθ
= (cosθ / sinθ) (1/cosθ)sinθ
= 1
The expression is equal to 1.

The length of each of the two congruent sides of an isosceles triangle is 2n + 7 and the length of the third side is 3n. Write an expression for the length of the triangle’s perimeter.
Answer:
7n+14
Step-by-step explanation:
There are two sides that both measure 2n+7, we need 2 of those
2n+7+2n+7=4n+14
We still have the third side left, 3n.
4n+14+3n
combine like terms
7n+14

What is an equation of the line that passes through the points (5, 8) and (5,3)?
Answer:
x = 5
Step-by-step explanation:
to find the slope of the line you take the difference of the y-values divided by the difference of the x-values; the denominator results in zero
When the denominator for slope is zero then you know the line will not intersect the y-axis at all and the line will be vertical and intersect the x-axis at the x-coordinate of any known point
any fraction with zero in the denominator is considered to be 'undefined'
any fraction with zero in the numerator is zero
On the first day, 8 adult tickets were sold and 13 student tickets were sold for a total of $75. On day two, 10 adult tickets were sold and 9 student tickets were sold for a total of $72. What is the cost of an adult ticket? What is the cost of a student ticket?
Step-by-step explanation:
8x + 13y = 75 (×10)
10x + 9y = 72 (×8)
80x + 130y = 750
-) 80x + 72y = 576
58y = 174
y = 3
10x + 9(3) = 72
10x + 27 = 72
10x = 72 - 27
10x = 45
x = 4.5
adult = $4.50

In a survey, 9 out of 10 dentists recommend PurWhite toothpaste for their patients. If 80 dentists were surveyed, how many doctors recommend PurWhite toothpaste?
Answer:
72 dentists
Step-by-step explanation:
In this case, we can multiply 80 by 9/10 or .9 to get our answer.
If we were to multiply by 9/10 it would look like this:
[tex]80 * \frac{9}{10} \\\frac{720}{10} = 72[/tex]
But, if we were to multiply by .90 (remember that 9/10 = .9) it would look like this:
[tex]80(.90) = 72[/tex]
Therefore, if 9 out of 10 dentists recommended PurWhite toothpaste and 80 were surveyed then 72 out of the 80 would have recommended it.
I hope this helps!!

Solve for the missing variable. Round your answer to the nearest tenth.
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
We assume the hash marks are intended to indicate both triangles are isosceles. Then the right-end angle of the upper triangle is ...
180° -2(75°) = 30°
Its complement is the supplement of the "missing variable" angle.
90° -30° = 180° -(18x -6)°
18x = 126 . . . . . rearranging (add 18x -60)
x = 7 . . . . . . . . . divide by 18
4. Find m_1.
140°
650
Answer:
∠ 1 = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
90° + ∠ 1 = 140° ( subtract 90° from both sides )
∠ 1 = 50°
Answer:
50 degrees
Step-by-step explanation:
To find the measure of angle 1, you must first find the other unknown angle in the triangle. You can find this through supplementary angles. The bottom angle as well as 140 must be equal to 180 because they are supplementary, so to find it solve 180-140, which is 40. Now two of the angles in the triangle are known, one is 40 and the other is 90 as shown by the square. You know that every angle equals 180 degrees, so to find angle 1 add the known angles and subtract that from 180. 180-(90+40), which equals 50. So m<1=50.
