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.)

Answer:

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

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

Answer:

-9,-21

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

x=-9

y=2(-9)-3=-18-3=-21

Answer:

that angle is 45°

so y = 5√3

and × = √2×y

x= √2 × 5√3

x=5√6

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]

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

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

Answer:

120

Step-by-step explanation:

Answer:

Step-by-step explanation:

cos(30) = Adj/hyp

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

[tex]\sqrt{12}[/tex] = y

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

I calculated it logically

Answer:

(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.

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

Answer:

19.63cm²

                  = 19.63cm²

Answer:

The answer is 36

Step-by-step explanation:

Because 39+1=40

So then 40-24=16

and then divided by 6 is 36 because when you divide you multiply

Answer: 1

Step-by-step explanation:

If x = 0

then, f(x) = 1 - 0

f(x) = 1

x = ±1

Let f(x)=0

Answer:

29

Step-by-step explanation:

f(3)=3f(2)-f(1)=3x4-1=11

f(4)=3f(3)-f(2)=3x11-4=29

Answer:

ok so you say I don't know for 10000000000 year's the end. :)

Answer:

It will be in the air until P(x) is zero.

P(x) = -16x2 + 32x = -16x(x - 2)

P(x) = 0 ⇒ x = 0 or x = 2

It starts on the ground at x = 0, so the total time in the air must be x = 2 seconds.

Answer:

  y = -5x -8

Step-by-step explanation:

The y-intercept can be found from ...

  b = y -mx

Using the first point, we have ...

  b = 2 -(-5)(-2) = -8

Then the slope-intercept equation is ...

  y = mx + b . . . . . . . . for slope m and y-intercept b

  y = -5x -8

Answer:

the answer is

y=-5×-8
