How to add angle pairs? Pls help

Answer: 80 degrees

Step-by-step explanation:

Answer:

B = 54 to the nearest degree.

Step-by-step explanation:

Remark

This is a sine law question. They can be rather nasty because no answer or 2 answers are possible. This one is well behaved because B, you are told, is acute. The two answer kind needs the supplement of an acute angle.

Sorry this blabs on and shouldn't. You are looking for <B

Formula

Sin(<B)/the side opposite = Sin(<A) / side opposite it

Simplified

Sin(<B) / 9 = Sin(A)/11

Sin(<B) / 9 = Sin(80) / 11             Multiply both sides by 9

9*Sin(B) / 9 = 9 * Sin(80) /11      The 9s Cancel

Now all you need to do is put it in your calculator. Do you need the steps?

Sin(B) = 9*sin(80) / 11

Sin(B) = 9 * 0.9848 /11

Sin(B)= 0.8058

B = Sin-1(0.8058)

B = 53.68

B = 54

Answer:

117

Step-by-step explanation:

By adding the percentages given: 3+16+14+18+10

you get 61%

multiply 300 by .61 or 61%

you get 183

subtract 183 from 300

you are left with 117 which is the answer

Answer:

[tex] d. 351.9 {cm}^{2} (ans)[/tex]

Step-by-step explanation:

Given,

Radius of the cylinder = 4cm

Height of the cylinder = 10 cm

Therefore,

Surface area of the cylinder

[tex] = 2\pi r(r + h)[/tex]

[tex] = 2 \times 3.15 \times 4(4 + 10) {cm}^{2} [/tex]

[tex] = 351.86 {cm}^{2} [/tex]

[tex] = 351.9 {cm}^{2} (ans)[/tex]

Three times the quotient of 3 and 5 is equivalent to 1.8

The question asked us to convert the word problem to equation and solve.

The quotient of 3 and 5 is expressed as 3/5

Taking the product of the result and 3 will give;

Three times the quotient of 3 and 5 = 3 * 3/5

Three times the quotient of 3 and 5 = 9/5 = 1.8

Hence three times the quotient of 3 and 5 is equivalent to 1.8

Answer:

-2x²+490x+2500

Step-by-step explanation:

Given that,

Demand, D(x) = 500-2x

The price for the product, P(x) = x+5

We need to find the revenue for the product. The formula for the revenue is given by :

Revenue = price × demand

Substitute all the values,

R = (x+5)(500-2x)

= 500x -2x² + 2500 -10x

= -2x²+490x+2500

So, the expression for the revenue function is "-2x²+490x+2500".

The division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the ratio is 4:11. the number is 405 which has to be divided by the ratio.

Let the common ratio between the numbers is x. Form an equation and solve for x.

4x + 11x = 405

15x = 405

x = 405 / 15

x = 27

The numbers are,

4x = ( 4 x 27 ) = 108

11x = ( 11 x 27 ) = 297

Therefore, the division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

Rotate one of them so the right angle is in the same orientation as the other one.

1. AB = DE

2. CB = FE

3. AC = DF

4. Compare the length of two known sides: cb and EF

CB = 3 and EF = 8

8/3 = 2 2/3 scale factor

5. Ab is side de. Multiply the length of ab by the scale factor:

4 x 2 2/3 = 10 2/3

6. FD = sqrt ( 10 2/3^2 + 8^2)

FD = 13 1/3

Got it right on Khan

From the given question, we can see that there is currently ten inches of snow.

With this in mind, we can see that the weather forecast for Monday is 50% probability for 2.5 inches of snow which is 1/2 for 2.5 inches of snow.

Furthermore, if it does not snow, then there would be 2.5-1.5= 1.0 inches of snow

Additionally, the weather forecast for Tuesday is 50% probability for 1.5 inches of snow which is 1/2 for 2.5 inches of snow.

Furthermore, if it does not snow, then there would be 1.5-0.5= 1.0 inches of snow

Given that the weather on Monday and Tuesday are independent events, then all the probabilities would be 1/2:1 which would be 0.5 inches of snow.

With this in mind, all the probabilities for chances of snow is 0.25

Therefore, we can see that all the possible values of x would be 0.25

Answer:

Step-by-step explanation:

All of its side are equal so it is an equilateral triangle. And as we all know an Equilateral triangle has 3 equal angles.

So based on this we can solve it using algebra,

[tex]3x + 3x + 3x = 180[/tex]

So using this we can find the value for x

[tex]9x = 180 \\ x = \frac{180}{9} \\ x = 20[/tex]

Of course it'll be smaller since it's a fraction of the whole number. 1/3 of 27 is 9

Answer:

Step-by-step explanation:

g(x) = √(32x) = √(2⁵x) = 4√(2x)

(f∘g)(x) = f(g(x))

= f(4√(2x))

= √(2 ⋅ 4√(2x))

= √(8√(2x))

= √8∜2∜x

= ∜(2⁷x)

= ∜(128x)

which doesn’t match any of the choices. There’s an error in the question.

Answer:

start at 3 1/8

1st teem = 3 1/8

2nd term = 3 1/8 - 3/4

                = 25/8 - 3/4

                = 25/8 - 6/8

                 =19/8

                 = 2 3/8

3rd term = 2 3/8 - 3/4

                = 19/8 - 3/4

                = 19/8 - 6/8

                 =13/8

                 = 1 5/8

4th term = 1 5/8 - 3/4

                = 13/8 - 3/4

                = 13/8 - 6/8

                 =7/8
