Step-by-step explanation:

(4d - 1)° + 105° = 180°

4d - 1 + 105 = 180

4d = 76

d = <em>19</em>

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 58-by-58 squar

Savatey [412]

Answer:

We need to find the area of the semicircles + the area of the square.

The area of a square is equal to the square of the lenght of one side.

As = L^2 = 58m^2 = 3,364 m^2

Now, each of the semicircles has a diameter of 58m, and we have that the area of a circle is equal to:

Ac = pi*(d/2)^2 = 3.14*(58m/2)^2 = 3.14(27m)^2 = 2,289.06m^2

And the area of a semicircle is half of that, so the area of each semicircle is:

a = (2,289.06m^2)/2 = 1,144.53m^2

And we have 4 of those, so the total area of the semicircles is:

4*a = 4* 1,144.53m^2 = 4578.12m^2

Now, we need to add the area of the square 3,364 m^2 + 4578.12m^2 = 7942.12m^2

This is nothing like the provided anwer of Val, so the numbers of val may be wrong.

A rectangular game board measures 126 centimeters by 90 centimeters. The game board is divided into small squares of equal size.

Ivahew [28]

The area of your game board is = 126 * 90 = 11340 cm^2;
A small suares has x^2 his area; where x measure his length;

Prime factorization

11340 | 2
5670 | 2
2835 | 5
567 | 3
189 | 3
63 | 3
21 | 3
7 | 7
1

11340 = 2^2 * 3^4 * 5 * 7 = 2^2 * ( 3^2 ) ^ 2 * 5 * 7 = 18^2 * 5 * 7

We observ that the possible length of the side is 18( we have 35 small squares ).

Identify the solution and graph of the given inequality. 34 > 3(2 − x)

zloy xaker [14]

Answer:

x > 28/3

Step-by-step explanation:

34 > 3(2 − x)

simplify the bracket

34 > 6 -3x

combine the like terms

34 - 6 > 3x

28 > 3x

divide by 3

x > 28/3

Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.

It is in slope intercept form; y = mx + b

where mx is the slope and b is the y-intercept;

x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times

And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.

Hope this helps!

Good luck.

Use the rational root theorem to list all possible rational roots for the equation.

Alik [6]

Answer:

The possible rational roots are

$\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$

Step-by-step explanation:

We have been given the equation 3x^3+9x-6=0 and we have to list all possible rational roots by rational root theorem.

The factors of constant term are $1, 2, 3,6$

The factors of leading coefficient are $1,3,$

From ration root theorem, the possible roots are the ratio of the factors of the constant term and the factors of the leading coefficient. We include both positive as well as negative, hence we must include plus minus.

$\pm\frac{1,2,3,6}{1,3}\\\\ =\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$
