Answer:

a = -8

Step-by-step explanation:

you can solve this proportion by cross-multiplying:

4(a + 9) = -1(a + 4)

now distribute to eliminate parentheses

4a + 36 = -1a - 4

5a + 36 = -4

5a = -40

a = -8

Answer:

$13.38

Step-by-step explanation:

Use proportions to solve this problem:

$20.07 / 3 bags  = X / 2 bags

multiply both sides by "2 bags" to isolate the unknown X

$20.07 * 2 / 3 = X

Therefore, X = $13.38

Answer and Step-by-step explanation:

22ft = x (c)

20ft = y (b)

18ft = z (a)

Plug into equation.

[tex]22^{2} = 20^{2} + 18^{2} - 2(20)(18)cosC (X)\\\\484 = 724 - 720cosC\\\\-240 = -720cosC\\\\\frac{1}{3} = cosC\\\\cosx^{1} (\frac{1}{3} ) = C\\\\C = 70.5288\\\\[/tex]

C ≈ 70.5 is the answer.

Answer:

The answer is 108

Step-by-step explanation:

I did this for my exam got 100

Together they can paint 5/108 of a wall in 1 minute.  So they can paint the entire wall in 108 minutes.

We have given that,

John can paint 1/54 of a wall in 1 minute.

James can paint 1/36 of a wall in 1 minute.

Total wall paint  of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute

Therefore ,total wall paint in one minute =1/54 + 1/36

So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.

1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.

Therefore,together they can paint 5/108 of a wall in 1 minute.  So they can paint the entire wall in 108 minutes.

Step-by-step explanation:

The correct expressions that represent the total number of inches braided by robin and Olivia is,

⇒ 4 (1/3g - 3)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Robin braided g inches of a friendship bracelet.

And, Olivia braided 12 less than 1/3 the number of inches robin braided.

Now, The total number of inches braided by Robin and Olivia = Number of inches braided by  Robin + Number of inches braided by Olivia

Hence, We get;

⇒ g + 1/3g - 12

⇒ 4/3g - 12

⇒ 4 (1/3g - 3)

Thus, The correct expressions that represent the total number of inches braided by robin and Olivia is,

⇒ 4 (1/3g - 3)

The trigonometric function gives the ratio of different sides of a right-angle triangle. The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse.

The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The angle of elevation is equal to,

The angle of elevation = Sin⁻¹ (4.5/11.75)

                                      = 22.5183° ≈ 23°

Hence, the angle of elevation formed by the ramp by the ground to the nearest degree is 23°.

Answer:

2.601

Step-by-step explanation:

Given that:

White balls, W = 5

Black balls, B = 3

Orange balls, O = 2

Total = (5 + 3 + 2) = 10

Winning = $2 for each black ball chosen

Winning = - $1 for each white ball

Sample space for making 2 selections ; order does not matter :

{WW, WO, WB, OO, OB, BB}

WW __WO __WB __OO ___OB __BB

-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4

WW = 5C2 / 10C2 = 0.2222

WO = (5C1 * 2C1) / 10C2) = 0.222

WB = (5C1 * 3C1) / 10C2) = 0.3333

OO = (2C2) / (10C2) = 0.0222

OB = ((2C1) * (3C1)) / 10C2 = 0.1333

BB = 3C2 / 10C2 = 0.0667

Expected winning = Σx * p(x)

(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)

= 2.601
