Set up the equation and solve.
Twice a number increased by 12 is 20. What is the number?

Answers

Answer 1

Answer:

2x+12 = 20

x = 4

Step-by-step explanation:

Twice a number = 2x

increased by 12 = +12

Format:

2x + 12 = 20

Solve

Subtract 12 from both sides

2x + 12 - 12 = 20 - 12

2x = 8

divide both sides by 2

2x/2 = 8/2

x = 4

If my answer is incorrect, pls correct me!

¿cuanto suman los angulos interiores de un hexagono? Escribe solo el numero que corresponda a la cantidad, sin el simbolo de grados

Answers

Answer:

La suma de los ángulos interiores de un hexágono regular es 720°

Step-by-step explanation:

Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

Given:BK=CH Which additional congruence statement could you use to prove that ∆BJK ≅ ∆CFH by the HL Theorem?

Answers

Answer:

Step-by-step explanation:

The hl theorem says that if we have two right triangles that have a congruent hypotenuse and a congruent leg, the two triangles are congruent

in this case the exercise says the two leg are congruent, so we have to say that the two hypotenuse are congruent

Find the value of x. 6 8 4 x

Answers

Answer:

3

Explanation:

4 is half of 8 on the right side, so that means X has to be half of 6, so it’s 3. Also, it couldn’t be 2 because it is too big, and it can’t be 4 because it isn’t the same length as the other 4, so it’s 3

The value of x in the figure which illustrates similar triangles is 3

How to determine the value of x?

The figure illustrates similar triangles.

This is represented by the following equivalent ratios

x : 6 = 4 : 8

Express as fraction

x/6 = 4/8

Multiply both sides by 6

x = 6 * 4/8

Evaluate the product

x = 3

Hence, the value of x in the figure is 3

The volume of this cylinder is approximately 416,992 cubic inches.

The height is ___ inches.

Use ​ ≈ 3.14.

Answers

Answer:

83

Step-by-step explanation:

height = [tex]\frac{volume}{\pi *r^{2} }[/tex]

height =  [tex]\frac{416992}{3.14*(40)^{2} }[/tex]

height = 83

Answer:

Step-by-step explanation:

V = pi * r^2 * h

V = 416992

r = 40 inches.

pi = 3.14

416992 = 3.14 * 40^2 * h

416992 = 3.14 * 1600 * h

416992 = 5024 * h

416992 / 5024 = h

h = 83

Step-by-step explanation:

alternate interior angles are congruent. and then 1 and 4 are supplementary angles which create 180

Answer:

Angle 2 is 60. Find angle 8

solution,

2=8(being co-alternate angle)

60=8

so, 8=60,,

If Angle 4 is 40 degrees. Find Angle 1
