6x+30=180

6x=180-30

x=150/6

x=25

therefore the value of x is 25 degree.

X=5/2
This is apparently an equalateril triangle so we can take any two angles and make them equal

M

Answers

Answer:

The interval notation would be (-∞, 3.9 feet) ∪ (6.3 feet, ∞).

Step-by-step explanation:

Since the lower and upper bounds are given, those very bounds extend to infinity in this case since there is no limit to the height which would be considered abnormal in this question. Using the lower bounds and upper bounds to construct an interval notation, we get the answer as shown above.

This circle graph shows the percent of land occupied by each continent.
The area of North America is approximately 220 million km2
.

Use the percents in the circle graph.
Find the approximate area of each of the other continents,
to the nearest million square kilometres.

Answers

The approximate areas of the continents (excluding North America) are as follows:

- Australia: 11 million km^2

- Europe: 15 million km^2

- Antarctica: 18 million km^2

- South America: 26 million km^2

- Africa: 44 million km^2

- Asia: 66 million km^2

To find the approximate area of each continent, we will multiply the given percentages by the area of North America (220 million km^2).

1. Australia:

Percentage: 5%

Approximate area: 0.05 * 220 million km^2 = 11 million km^2

2. Europe:

Percentage: 7%

Approximate area: 0.07 * 220 million km^2 = 15.4 million km^2 (rounded to 15 million km^2)

3. Antarctica:

Percentage: 8%

Approximate area: 0.08 * 220 million km^2 = 17.6 million km^2 (rounded to 18 million km^2)

4. South America:

Percentage: 12%

Approximate area: 0.12 * 220 million km^2 = 26.4 million km^2 (rounded to 26 million km^2)

5. Africa:

Percentage: 20%

Approximate area: 0.20 * 220 million km^2 = 44 million km^2

6. Asia:

Percentage: 30%

Approximate area: 0.30 * 220 million km^2 = 66 million km^2

Note: These values are rounded to the nearest million square kilometers.

If sin θ +cosec θ = 2 then sin2θ+ cosec2θ is equal to

a) 1 b) 4

c) 2 c) 9

Answers

Answer:

C

Step-by-step explanation:

We are given that:

[tex]\sin \theta +\csc \theta = 2[/tex]

And we want to find the value of:

[tex]\sin^2\theta + \csc^2\theta[/tex]

From the first equation, we can square both sides:

[tex](\sin \theta + \csc \theta)^2=(2)^2[/tex]

Square:

[tex]\sin ^2\theta +2\sin\theta\csc\theta +\csc^2\theta =4[/tex]

Let csc(θ) = 1 / sin(θ):

[tex]\displaystyle \sin ^2\theta +2\sin\theta\left(\frac{1}{\sin \theta}\right) +\csc^2\theta =4[/tex]

Simplify:

[tex]\displaystyle \sin ^2\theta +2(1) +\csc^2\theta =4[/tex]

Therefore:

[tex]\sin ^2\theta + \csc^2\theta =2[/tex]

Our answer is C.

You purchase 75 shares of stock at $15 per share. The next day the stock drops 3%; however, a week later it increases in value by 7%. If you immediately sell your 75 shares, how much will you gain or lose (a) in dollar amount and (b) in percent?

Answers

Answer:

You have gained $43 and the value increased by 3.8%

Step-by-step explanation:

You would 75 times 15 = $1125

then you would do 1125 times 97% = 1091.25

now you would do 1091.25 times 107% = estimation of 1168

then you would do 1168/1125 which is estimated to 1.038 and you would convert that into a percentage = 103.8%

You would do 1168 - 1125 = $43 and 103.8 - 100 = 3.8%

What is the lateral area of the pyramid?

Answers

Answer:

160.

Step-by-step explanation:

The area of the base is 64 since each side is 8, 8x8 is equal to 64. Then you have the lateral faces with a length of 8, and a height of 6, which is 48, but since they are triangles, you divide by 2, finally add 24+24+24+24+64 and your final answer is 160.

Step-by-step explanation:

8(2x - 9) = 4(5 + 4x) solve for x

Answers

Answer:

No solutions

Step-by-step explanation:

8(2x - 9) = 4(5 + 4x)

Distribute the 8

16x - 72 = 4(5 + 4x)

Distribute the 4.

16x - 72 = 20 + 16x

Add 72 to both sides

16x = 92 + 16x

Subtract 16x from both sides

0 = 92

0 does not equal 92 therefore there are no solutions

Answer:

No solution

Step-by-step explanation:

8(2x - 9) = 4(5 + 4x)

Simplify

8(2x−9).

Start simplifying.

0+0+8(2x−9)=4(5+4x)

Simplify by adding zeros.

8(2x−9)=4(5+4x)

Apply the distributive property.

8(2x)+8(−9)=4(5+4x)

Multiply 2 by 8.

16x+8(−9)=4(5+4x)

Multiply 8 by −9.

16x−72=4(5+4x)

Simplify

4(5+4x).

Apply the distributive property.

16x−72=4×5+4(4x)

Multiply 4 by 5.

16x−72=20+4(4x)

Multiply 4 by 4.

16x−72=20+16x

Move all terms containing x to the left side of the equation.

Subtract 16x from both sides of the equation.

16x−72−16x=20

Combine the opposite terms in

16x−72−16x.

Subtract 16x from 16x.

0−72=20

Subtract 72 from 0.

−72=20

Since −72 ≠ 20, there are no solutions.
