9. Find the length AD of the shape given below, giving your answer correct to 2
decimal places.

Answers

Answer:

Length of AD = 10.47 meter (Approx.)

Step-by-step explanation:

Given:

Triangle ACB is a right angle triangle

Length of AC = 14.8 m

Length of CB = 5.5 m

Length of CD = 6.4 m

Find:

Length of AD

Computation:

Using Pythagorean theorem

Base = √Hypoteneus² - Perpendicular²

Length of AB = √14.8² - 5.5²

Length of AB = 13.74 m

Length of DB = √6.4² - 5.5²

Length of DB = 3.27

Length of AD = Length of AB - Length of DB

Length of AD = 13.74 - 3.27

Length of AD = 10.47

Length of AD = 10.47 meter (Approx.)

Find the missing side of each right triangle (Pythagorean’s #Theorem)

Answers

Answer:

3

Step-by-step explanation:

The formula for the Pythagorean's Theorem is a^2 + b^2 = c^2, so first you know that hypotenuse is the longest side or the opposite side from which the right angle is which in this case is the 6 so you are looking for a leg rather then the hypotenuse which means we are going to be doing subtraction.

a^2 + b^2 = c^2

√27^2 - b^2 = 6^2

27 - b^2 = 36

-27            -27

         b^2 = 9

         b^2 = √9

         b = 3

Two numbers have a difference of 12. The smaller of the two numbers is 3 less than double the other. What are the two numbers?

Step-by-step explanation:

let the numbers be x and y and x>y

x-y=12

y=2x-3

x-(2x-3)=12

x-2x+3=12

-x=12-3

-x=9

Answers

Answer:

[tex] V_{cylinder} =16,579.2\: in^3 [/tex]

Step-by-step explanation:

Inner radius [tex] (r_1)[/tex] = 20/2 = 10 in

Outer radius [tex] (r_2)[/tex] = 24/2 = 12 in

Height of the cylinder (h) = 120 in

[tex] \because V_{cylinder} =\pi( r_2^2-r_1^2) h[/tex]

[tex] \therefore V_{cylinder} =3.14(12^2-10^2) 120[/tex]

[tex] \therefore V_{cylinder} =376.8(12^2-10^2) [/tex]

[tex] \therefore V_{cylinder} =376.8(144-100) [/tex]

[tex] \therefore V_{cylinder} =376.8(44) [/tex]

Find value of x that will make a||b

Answers

Answer:

x = 4

Step-by-step explanation:

If line A is parallel to line B, therefore,

9x + 4 = 5x + 20 (alternate interior angles theorem)

Solve for x. Collect like terms together

9x - 5x = -4 + 20

4x = 16

Divide both sides by 4

4x/4 = 16/4

x = 4

Therefore, the value of x that will make lime A parallel to line B is 4

Step-by-step explanation:

cos(30)  = 6 /x

x = 6 / cos(30)

x = 6 / ( [tex]\sqrt{3}[/tex]/ 2)

x = 12 / [tex]\sqrt{3}[/tex]

(  12 / [tex]\sqrt{3}[/tex] )^2  = 6^2 + y^2

(  12 / [tex]\sqrt{3}[/tex] )^2 - 36 = y^2

144/3 -36 = y^2

48-36=y^2

12 = y^2

Identify JK. JK and JM are tangent to W.

Answers

Answer:

B. 8

Step-by-step explanation:

Based on the tangent theorem, when two tangents meet at an external point of a circle, the length of the two tangents are said to be equal in length.

Therefore:

JK = JM

Substitute

5x - 12 = x + 4

Collect like terms

5x - x = 12 + 4

4x = 16

4x/4 = 16/4

x = 4

✔️JK = 5x - 12

Plug in the value of x

JK = 5(4) - 12

JK = 20 - 12

JK = 8

(2 * 60 / 30) * (24 + 2) is not equal to 30

Step-by-step explanation:

1. (9 * 10) / (4 + 1 ) + 12 = 30

2. 2 + (30 - 8 / 4) = 30

3. (2 * 60 / 30) * (24 + 2) = 104 [not equal to 30]

4. (120 / 20) * (2 + 3) = 30

Therefore, the third expression is not equal to 30.

There are six households in a rural community. Each household earns $40,000 per year. Suppose that a new resident builds a mansion in the community and that the income in the new household is $4 million per year. After the new resident arrives, the median household income has _____, and the mean household income has _____. increased; increased not changed; increased not changed; not changed increased; not changed

Answers

Answer:

Median income has not changed

Mean income has increased

Step-by-step explanation:

Initial number of houses = 6

Earning per household = $40,000

The initial mean :

$(40,000 * 6) / 6 = $40000

Initial median :

40000, 40000, 40000, 40000, 40000, 40000

= 1/2(n+1)th term,

Median = 40000

A 7th household earns 4,000,000

Mean = ((40000*6) + 4,000,000) / 7 = $605,714

Median = 1/2(n+1)th term

40000, 40000, 40000, 40000, 40000, 40000, 4000000

Median = 4th term = 40000
