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

hope this helps

have a happy holidays:)

Answer:

A. -86

Step-by-step explanation:

The absolute value is the distance a number has from zero.

Two numbers that are the same, except that one is positive and negative, will have the same absolute value.

So, -86 and 86 have the same absolute value of 86. This is because they are both 86 away from 0.

So, A is the correct answer.

Checking for a perfect cube :

Trying to factor by pulling out :

3.2 Factoring: 3m3 + 5m2 - 5m + 1

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -5m + 1

Group 2: 5m2 + 3m3

Pull out from each group separately :

Group 1: (-5m + 1) • (1) = (5m - 1) • (-1)

Group 2: (3m + 5) • (m2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

3.3 Find roots (zeroes) of : F(m) = 3m3 + 5m2 - 5m + 1

Polynomial Roots Calculator is a set of methods aimed at finding values of m for which F(m)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers m which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 8.00

-1 3 -0.33 3.11

1 1 1.00 4.00

1 3 0.33 0.00 3m - 1

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

3m3 + 5m2 - 5m + 1

can be divided with 3m - 1

Polynomial Long Division :

3.4 Polynomial Long Division

Dividing : 3m3 + 5m2 - 5m + 1

dividend 3m3 + 5m2 - 5m + 1

- divisor * m2 3m3 - m2

remainder 6m2 - 5m + 1

- divisor * 2m1 6m2 - 2m

remainder - 3m + 1

- divisor * -m0 - 3m + 1

remainder 0

Answer is 3

Here as by the given information ,

♦ sinA = Opposite/Hypotenuse

♦ cosA = Adjacent/Hypotenuse

♦ TanA = Opposite/adjacent

So here we need to find the same for angle B so we need to use the same formulas for angle B also .

→ sinB = Opposite/Hypotenuse = 12/13

→ cosB = Adjacent/Hypotenuse = 5/13

→ tanB = Opposite/Adjacent = 12/5

Step-by-step explanation:

To find out how much more money Olivia spent per apple, we need to find out how much each spent on one apple.

Cassie:

2 apples --- $4

1 apple --- $4 ÷ 2 = $2

Olivia:

5 apples --- $15

1 apple --- $15 ÷ 5 = $3

Difference per apple = $3 - $2

                                   = $1

Answer: 1/125

Answer: 24

Step-by-step explanation:

Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.

800 - 200 = 600.

Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.

600 ÷ 25 = 24.

So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.

Hope this helps!

$145

Step-by-step explanation:

When you do this type of problem, you want to find the unit rate. In order to do that you divide $116 by 16, and you get $7.25 (how much she make in one hour). Then you multiply $7.25 by 20, and get $145.

Answer:

Step-by-step explanation:

Given:

A geometric figure.

To find:

The point of tangency in the given figure.

Solution:

We know that, the point of tangency is a point where the tangent line touches the curve.

From the given figure it is clear that, two lines touch the circle at R and Z.

These two lines are tangent and they touch the curve at points R and Z. So, R and Z are point of tangency.

Therefore, the correct option is C.

printer C-  115/5

first, multiply 1.5 x 10, 3 x 5, and 5 x3

you should get 15 for each.

once you have the denominators all done, multiply the numerators by the value you multiplied the denominator by and you should have your answer.

so all in all, printer B prints the fastest

first subtract how tall is was 7 1/2 years ago from hell with all it is now. 57 - 40.5 = 16.5 or 16 1/2 so and the seven and a half years the tree Grace 16.5 with 16 1/2 seats to get the average yearly growth for the 7 1/2 year. You have to divide 16 and 1/2 ft by 7 and 1/2 Tim Wiles it makes it much easier if you change the fractions to decimals

Answer:

20 meters

Step-by-step explanation:

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?

We would have to find the perimeter of this rectangle

Perimeter fo a rectangle = 2L + 2W

In the above question,

L = Length = 40 m

W = Width = 20 m

Hence:

Perimeter = 2(40m) + 2(20m)

= 80m + 40m

= 120m

Hence, he would need 120 meters of tape

From the above Question, the company already has 100m

Hence, the amount of tape that the company needs more =

120m - 100m = 20 m

Answer:

Step-by-step explanation:

This problem can be worked in your head.

If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.

__

We can let s represent the side length of the octagon. Then we have ...

  8s = perimeter of octagon

  4(s +6) = perimeter of square

These are equal, so ...

  4(s +6) = 8s

  s +6 = 2s . . . . . . divide by 4

  6 = s . . . . . . . . . . subtract s

The octagon has 6-ft sides; the square has 12-ft sides.

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

Answer:

35

Step-by-step explanation:

let us take each boy's weight as x

therefore,

average = [tex]\frac{x+x+50}{3\\}[/tex]

40 = [tex]\frac{x+x+50}{3\\}[/tex]

40 x 3 = x + x + 50

120 - 50 = 2x

70 = 2x

2x = 70

x = [tex]\frac{70}{2}[/tex]

x = 35

So weight of each boys is 35.
