Answer 1

Answer: B. 21 in. A heptagon has seven sides, each side has the same measure. 3x7 equals 21.C. Regular polygon. It is called regular because of the regularity of all the sides.D. 32 feet. An octagon has 8 sides. 4x8 equals 32.A.The surface of a flat table.C.140Â°. To have supplementary angles means to have two angles that joined together they add 180.7. The answer should be 9.42 centimeters, since the diameter is the same size of that of the bottom.D. 4,605 ft. A pentagon counts with 5 sides, these 5 sides of 921 each one, add 4,605.

Answer 2

Answer:

Part 2) What's the perimeter of a regular heptagon if one side measures 3 inches?

we know that

The number of sides in a regular heptagon is equal to $7$

The perimeter is equal to

$P=7*a$

where

a is the length side

in this problem

$a=3\ in$

substitute

$P=7*3 =21\ in$

therefore

the answer Part 2) is the option

B. 21 in.

Part 3) A polygon that has all sides the same measure and all angles the same measure is called what?

we know that

When all angles are equal and all sides are equal, is a polygon that is equiangular and equilateral, so, is called a regular polygon

therefore

the answer part 3) is the option

C. Regular polygon

Part 4) The gazebo in the park is an octagon. Each side of the gazebo is 4 feet long. What is the perimeter of the gazebo?

we know that

The number of sides in a octagon is equal to $8$

The perimeter is equal to

$P=8*a$

where

a is the length side

in this problem

$a=4\ ft$

substitute

$P=8*4 =32\ ft$

therefore

the answer Part 4) is the option

D. 32 feet

Part 5) Which of the following best describes a plane?

we know that

--The edge of a desk is a piece of a straight or curved line.

-- A curve in a road is a piece of a curved line.

-- The intersection of two walls is a piece of a straight line

therefore

the answer Part 5) is the option

A. The surface of a flat table

Part 6) Two angles are supplementary. The first angle measures 40°. What's the measurement of the second angle?

we know that

Two angles are supplementary if the sum of their angles is equal to $180$ degrees

Let

x------> the measure of the second angle

$40+x=180\n x=180-40\n x=140\ degrees$

therefore

the answer Part 6) is the option

C. 140°

Part 7) In order for a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 9.42 centimeters?

we know that

The circumference is equal to

$C= \pi D$

where

D is the diameter

solve for D

$D=(C)/(\pi)$

$D=(9.42)/(\pi)$

$D= 3\ cm$

therefore

the answer Part 7) is the option

C. 3 centimeters

Part 8) The Pentagon in Washington DC is immense in size, with each outside wall 921 feet in length. What is the perimeter of the Pentagon?

we know that

The number of sides in a pentagon is equal to $5$

The perimeter is equal to

$P=5*a$

where

a is the length side

in this problem

$a=921\ ft$

substitute

$P=5*921 =4,605\ ft$

therefore

the answer Part 8) is the option

D. 4,605 ft.

Answers

$2x-[4-3(2^5+18y)]\n\n=2x-[4-3(32+18y)]\n\n=2x-(4-96-54y)\n\n=2x-(-92-54y)\n\n=2x+92+54y$

= 2x - [4 - (96 + 54y)]
= 2x - 4 + 96 + 54y

Consider a game in which players roll a number cube to determine the number of points earned. If a player rolls a prime number, that many points will be added to the player’s total. Any other roll will be deducted from the player’s total. What is the expected value of the points earned on a single roll in this game?

Answers

The expected value of the points earned on a single roll in the game would take into account the probability of the numbers of the cube and whether or not they're prime. If the cube is a dice with numbers 1 to 6, then the expected value of the points would be:
P = 1(1/6) + 2(1/6) + 3(1/6) - 4(1/6) + 5(1/6) - 6(1/6)
P = 1/6 or 0.1667

Answers

Let the number be x

According to your question,

6x - (-10) = -44

6x+10 = -44

6x = -54

thus, x = -54/6 = -9

Thus, x = -9

Thus, the number is -9

$\huge\boxed{\boxed{\bold{(3, 1)}}}$

$\hrulefill$

I'm assuming you need to find the solution to this system of equations (where the lines intersect).

We can use the substitution method to solve this system. Take the value of $y$ from the second equation and substitute it into the first:

$-2x+7=x-2$

Add $2x$ to both sides of the new equation:

$7=3x-2$

Now add $2$ to both sides of the equation:

$9=3x$

Divide both sides by $3$ :

$\boxed{3}=x$

Now let's solve for $y$ by substituting the known value of $x$ into the first equation:

$y=3-2$

Simplify using subtraction:

$y=\boxed{1}$

This means our solution is:

$\large\boxed{(3, 1)}$

Answer:

x = 3, y = 1

Step-by-step explanation:

Solve the following system:

{y = x - 2 | (equation 1)

y = 7 - 2 x | (equation 2)

Express the system in standard form:

{-x + y = -2 | (equation 1)

2 x + y = 7 | (equation 2)

Swap equation 1 with equation 2:

{2 x + y = 7 | (equation 1)

-x + y = -2 | (equation 2)

Add 1/2 × (equation 1) to equation 2:

{2 x + y = 7 | (equation 1)

0 x+(3 y)/2 = 3/2 | (equation 2)

Multiply equation 2 by 2/3:

{2 x + y = 7 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 6 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 3 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = 3, y = 1
