shown is a regular pentagon, find y.

Answer:

A. 33.3%

Step-by-step explanation:

On a dice, we have the numbers 1, 2, 3, 4, 5, and 6. The question is asking for the probability of anything greater than 4. This means we're trying to find the probability of rolling a 5 or a 6 since those are the only numbers greater than 4 on a dice. We can write this as a fraction.

There are six numbers total, so that will be the bottom of our fraction. We have two numbers that are greater than 4. This means we will write our fraction like so:

[tex]\frac{2}{6}[/tex]

Next, we can simplify the fraction by 2, leaving us with 1 over 3, like this:

[tex]\frac{2}{6} = \frac{1}{3}[/tex]

Finally, just divide the 1 by 3 to get 0.333, or 33.3% when you move the decimal two places to the right. Hope this helps!

Answer:

x=28

Step-by-step explanation:

Sum of all the angles in the triangle add up to equal 180

90 + x + 6 + 2x = 180

combine like terns

96 + 3x = 180

subtract 96 from each side

180-96=84

96-96 cancels out

3x=84

divide each side by 3

84/3=28

3/3 cancels out

x=28

=========================================

Explanation:

The quadrilateral shown is a kite since we have adjacent sides that are the same length (due to the similar tickmarks). The diagonals of any kite intersect to form a 90 degree angle.

The triangle in the lower left corner has the three angles of

Those three interior angles must add to 180. This is true of any triangle.

90+(x+6)+(2x) = 180

3x+96 = 180

3x = 180-96

3x = 84

x = 84/3

x = 28

Answer:

2,650

Step-by-step explanation:

Answer:

b = 12.6

Step-by-step explanation:

a*2 + b*2 = c*2

6*2 + b*2 = 14*2

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36             -36

b*2 = 160

Find the square root of both

b = 12.64911064  or 12.6

Answer:

In an isosceles right triangle, the equal sides make the right angle. ... Therefore each of those acute angles is 45°.

Answer:

acceleration, measurement of the mass, the volume. (non examples of speed)

Step-by-step explanation:

Step-by-step explanation:

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]

Step-by-step explanation:

let the speed of car A be A

let the speed of car B be B

according to the first condition:

[tex]\quad A=B+20[/tex]

according to the second condition:

[tex]\quad 156(A)=208B[/tex]

therefore

[tex]\text{the speed of car A is 60+20=80}[/tex]

Answer:

Explanation:

1 quart = 4 cups

1 gallon = 16 cups

Yesenia buys 1 quart -> 4 cups

AND 1/2 a gallon -> 8 cups

4 cups from quart + 8 cups from 1/2 gallon = 12 cups total!

Answer:

12th triangular number is 78

50th triangular number is 1275

Step-by-step explanation:

12+1=13

12÷2=6

6x13=78

if you do this for 50 you get 1275

Answer:

Step-by-step explanation:

12 number

Wherever you see an n put in 12

12 (12 + 1)/2

12 * 13 / 2

6 * 13

78

The 12th triangular number is 78

50th triangular number

Again, wherever you see an n put in 50

n/2 * (n+ 1)

50/2 * (50 + 1)

25 * 51

1275

Answer:

AC = 12

Step-by-step explanation:

From the question, we have that BD is perpendicular to AC

This means that it is at 90 degrees to the base

so we have two similar right triangles

Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)

Let us call the leg x

We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides

10^2 = x^2 + 8^2

100 = x^2 + 64

x^2 = 100-64

x^2 = 36

x = √36

x = 6

AD = DC = 6

AC = 2 * AD

AC = 2 * 6

AC = 12

Answer:

x-10

Step-by-step explanation:

you have to do what is in the parenthesis first. Do distributive property to

-(x-8)

-(x)-(-8)= -x+8

now you have 5-(3-x+8)

Do distributive property again

5-3+x-8

x-8+2

x-10

Answer:

14 7/24

Step-by-step explanation:

There are two different denominators here:  6 and 24.  The LCD is 24, and so 8 5/6 becomes 8 20/24.

Then the SUM of the two given mixed numbers is:

8 20/24 + 5 11/24 = 13 31/24, or, when properly reduced, 14 7/24

Answer:

4

Step-by-step explanation:

Multiply 4/3 to both sides to cancel out the 3/4 on the left.

Next, subtract 8 from both sides to cancel out the 8 on the left.

This should result in the equation x = 4!

Answer:

x = 4

Step-by-step explanation:

3/4 times x = 3/4x

3/4 times 8 = 6

9 - 6 = 3

3 / (3/4) = 4

Answer:

the answer is 915

Step-by-step explanation:

tell me if I'm wrong okay

Answer:

Correct answer is the first one x^2 + 2x - 8

because (x + 4) (x - 2)

= x ^2 + 4x - 2x - 8

= x^2 + 2x - 8

Answer:

A Bill le pagan $14 cada hora.

Step-by-step explanation:

Para conocer la cantidad que a Bill le pagan cada hora, se define una ecuación.

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos. Es decir, una ecuación se define como una igualdad establecida entre dos expresiones, en la cual puede haber una o más incógnitas que deben ser resueltas.

En este caso, es conveniente definir la siguiente incógnita:

Si cada hora que trabaja Bill aparta $6 para dárselos a su mamá, entonces cada hora recibirá: x - 6

Bill trabaja 3 horas al día, por lo que en ese día recibirá 3horas*(x-6). Y si la cantidad total con que se queda cada día es $24, entonces la ecuación a resolver será:

3*(x -6)= 24

Resolviendo, obtienes:

3*x - 3*6= 24

3*x - 18= 24

3*x= 24 +18

3*x= 42

x= 42÷ 3

x= 14

Entonces, a Bill le pagan $14 cada hora.
