Answer:

BC ≈ 5.44 m

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is

cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )

6.1 × cos27° = BC , then

BC ≈ 5.44 m ( to 3 significant figures )

Answer:

y = 12x + 10

X = y/12 - 5/6

Answer:

y = 12x + 10

x = (y-10)÷12

Answer:

The missing reason for the 3rd step in the proof below is;

C. Vertical angles are congruent

Step-by-step explanation:

In the two column proof, we have;

Statement   [tex]{}[/tex]            Reason

1. AB ║ CD   [tex]{}[/tex]           1. Given

2. ∠3 ≅ ∠7   [tex]{}[/tex]           2. Corresponding angles theorem

3. ∠7 ≅ ∠6   [tex]{}[/tex]           3. Vertical angles are congruent

4. m∠3 = m∠7   [tex]{}[/tex]      4. Definition of congruence    

m∠7 = m∠6

5. m∠3 = m∠6    [tex]{}[/tex]      5. Substitution

6. m∠3 ≅ m∠6    [tex]{}[/tex]     6. Definition of congruence

Vertical angles are the angles formed on the opposite sides of two straight lines when they cross each other

Other vertical angles in the diagram are;

1) ∠5 and ∠8

2) ∠1 and ∠4

3) ∠2 and ∠3

Answer:

27

Step-by-step explanation:

4 1/2  = 9/5

9/2 : 1/6  =

9/2 x 6/1 =

(9x6) / (2x1) =

54/2  = 27

Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4

Step-by-step explanation:

Answer: [tex]\frac{2(x-7)}{5(x-3)(x-2)}[/tex]

Step-by-step explanation:

I'll do the fraction on the left, then the one on the right. Follow the screenshots below to help you out.

1. Use distributive property. The first of the images is me distributing all the values on the fraction on the left. Now I will do the ones on the left.

2. I used the same method. Now I will multiply the two.

3. [tex]\frac{2(x-7)}{5(x-3)(x-2)}[/tex]

Answer:

263 / 280

Step-by-step explanation:

Given that :

Number of tickets bought = required outcome = 17

Total number of raffle = total possible outcomes = 280

Probability = required outcome / Total possible outcomes

P(winning) = 17 / 280

P(not winning) = 1 - 17/ 280

= 263 / 280

Answer: Question 1 is correct and Question 2 is 12 degrees :)

Step-by-step explanation: hope this helped!

Answer:

y =-5x + 7

Step-by-step explanation:

y = -5x + 4

Slope = -5

Parallel lines have same slope

Slope of the parallel line to this line = -5

(1 , 2)

y -y1 =m(x - x1)

y - 2 = -5(x - 1)

y -2 = -5x + 5

   y = -5x + 5 + 2

  y = -5x + 7

Answer:

y = 2.0x + 0.6

Step-by-step explanation:

Dino's data:

X _____ Y

1 ______ 1

2 ______5

3 ______6

4 _____ 10

5 _____ 13

6 _____ 13

7 _____ 14

8 _____ 16

9 _____ 18

10 _____21

Using the linear regression calculator, the line of best fit for the data is :

y = 2.0X + 0.6

Where ;

Slope = 2 ; intercept = 0.6

Answer:

y = 4(3)^x

Step-by-step explanation:

Here, we want to write the exponential equation

From the question, we have the equation tripling in x value every year and the original amount is 4

The exponential equation is of the form;

y = a(b)^n

In this case;

a = 4 , b = 3 and n = x

So we have the equation as;

y = 4(3)^x

Step-by-step explanation

Step-by-step explanation:

(x-3)(2x+1)(x+1)

(2x² - 6x + x - 3)(x+1)

(2x² - 5x - 3) (x+1)

2x³ -5x² -3x + 2x² -5x - 3

2x³ - 3x² - 8x -3

Answer:

at least 125 points on the final

Step-by-step explanation:

90% of 650 = 585

He needs at  least 585 points to get at least 90%

Since he averaged 92 on the first 5 tests, he already has 5(92) = 460 pts

That means he needs to get at least 585 - 460 = 125 pts on the final exam
