Solve For X. Show All Work.

Answers

Answer 1

Answer:

x = 10.

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7

7(3x - 5) = 5(3x + 5)

21x - 35 = 15x + 25

6x = 60

x = 10.

Answer 2

Answer:

x= 10

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7

7(3x - 5) = 5(3x + 5)

21x - 35 = 15x + 25

6x = 60

x = 10.

Determine the volume of a cube with sides of 30mm

Answers

Answer: Hello, your answer would be [tex]2.7x10^-5m^3[/tex]

Step-by-step explanation:

[tex]30mm[/tex]

[tex]a=0.03m[/tex]

[tex]V=a^3=0.03^3=2.7x10^-5m^3[/tex]

(the answer is also in the picture)

Answer:

V≈2.7×10^-5m³

Step-by-step explanation:

a=edge

Unit Conversion:

a=30mm/1000m

a=0.03m

Solution

V= a³= 0.03³

a³=0.03x0.03x0.03 ≈ 2.7×10^-5m³

Step-by-step explanation:

n + n^2 = 6 n^2 + n - 6 = 0 factoring ___ (n + 3)(n - 2) = 0 n + 3 = 0 ___ n = -3 n - 2 = 0 ___ n = 2 two solutions 

Answer:

n = -3, 2

Step-by-step explanation:

We're given:

The sum of a number and its square is 6

Let the number be n.

The sum of a number and its square is 6⇒ [tex]n+n^2=6[/tex]

[tex]n+n^2=6[/tex]

⇒ Move everything to one side of the equation:

[tex]n+n^2-6=0[/tex]

⇒ Organize in [tex]ax^2+bx+c=0[/tex] form:

[tex]n^2+n-6=0[/tex]

⇒ Factor:

[tex]n^2-2n+3n-6=0\\n(n-2)+3(n-2)=0\\(n+3)(n-2)=0[/tex]

⇒ Use the zero-product property to find n:

[tex]n+3=0\\n=-3[/tex]       or       [tex]n-2=0\\n=2[/tex]

In circle O, AD and BE are diameters. The measure of arc AB is 55° and the
measure of arc CD is 25º.
What is the measure of BC?
80
110
90
100

Answers

100. the diameter means the other half, so arc AD is 180 on both sides. so that means we can do 180-(25+55), which equals 100

Answer:

Arc AB = 55°

Angle AOB = 55° ( Centre angle is equal to respective arc )

Arc CD = 25°

Angle COD = 25° ( Centre angle is equal to respective arc )

Angle AOB + Angle BOC + Angle COD = 180° ( AD is the diameter)

55° + Angle BOC + 25° = 180°

Angle BOC + 80° = 180°

Angle BOC = 100°

(4x -4)° +x° +(6x-3)° = 180°J = 99°K = 64°L = 17°

Step-by-step explanation:

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

__

equation

  (4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

solution for x

  11x -7 = 180 . . . . . . . divide by °, collect terms

  11x = 187 . . . . . . . . add 7

  x = 17 . . . . . . . . . divide by 11

angle values

  m∠J = (6x -3)° = (6(17) -3)° = 99°

  m∠K = (4x -4)° = (4(17) -4)° = 64°

  m∠L = x° = 17°

James ordered a $10.20 meal and Mark ordered a $9.50 meal. If the sales tax is 7% and they leave a 15% tip on the price of the meal including tax, then what was the tota!?

Answers

Answer:

The total cost of the meal is $24.24

Step-by-step explanation:

Step 1: Combine the two meal costs.

10.20 + 9.50 = 19.70

Sales tax is 7%, so multiply 19.70 by 0.07 then add the sum to 19.70

19.70 * 0.07 = 1.379

19.70 + 1.379 = 21.079

They leave a 15% tip on the meal, including tax, so take 15% of 21.079 or 21.079 * 0.15, which equals 3.16185

Add 3.16185 to 21.079

This equals 24.24085

A function is shown below.
f(x) = 8x - 11

What value of x makes f(x) = 21?

Answers

f(x)=8x-11
f(21)
x=21
f(21)=8(21)-11
f(21)=168-11
f(21)=157

The correct value in this function is f(21) = 157

This question is related to substitution of values. To solve it, just: change x by the indicated value and thus calculate normally.

– The given function being f(x) = 8x - 11, replace X by 21:

f(x) = 8x - 11

f(21) = 8 . 21 - 11

– Finally, just calculate the expression now, like this, multiplying and subtracting the numbers:

f(21) = 8 . 21 - 11

f(21) = 168 - 11

f(21) = 157

Therefore, the correct value of this function will be f(21) = 157

From the top of a 180-foot tall lighthouse, the angle of
depression to a ship in the ocean is 27º. How far is the
ship from the base of the lighthouse?
inch tall me

Answers

Reading the given Question , we get to know that 180 ft. is the height of lighthouse and 27° is the angle of depression from top of it to a ship in the ocean

(Figure is attached )

We know , Angle Of depression = Angle Of elevation

For finding base length from the ship to base of lighthouse ,

Tanθ = perpendicular/base

Tan 27° = 180ft/base

Base = 180/0.5095 (Value of tan 27° is 0.5095)

Base = 353.28 ft.

Base = 4239.36 inches
