Name all polygons shapes

Answers

Answer 1
Answer:

Polygons are closed plane figures with straight sides. Here are some examples of polygon shapes:

  • Triangle (3 sides)
  • Quadrilateral (4 sides)
  • Pentagon (5 sides)
  • Hexagon (6 sides)
  • Heptagon (7 sides)
  • Octagon (8 sides)

What are polygons

Polygons are two-dimensional, closed geometric shapes with straight sides. These shapes are formed by connecting a sequence of line segments end-to-end to create a closed figure.

Other polygons are:

  • Nonagon (9 sides)
  • Decagon (10 sides)
  • Undecagon (11 sides)
  • Dodecagon (12 sides)

The study of polygons is an essential part of geometry and lays the foundation for understanding various geometric properties and concepts.

When I triple my number and add five I get 26 what is my number

Answers

Let the number be X
3x+5=26
3x= 26-5
3x=21
x=7
The number is 7

Proof if it is required on your test:
3x+5=26
3(7)+5= 26
21+5=26
26=26

(Hope this helps!)
My numbe is 7 because...

3x + 5 = 26
- 5 = 21
3x = 21
Divide 3x by 3 then 21 by 3
That leaves with 1x = 7

Whats 95.131 rounded to the nearest hundredth

Answers

Answer:

95

Step-by-step explanation:

To round 95.131 to the nearest whole number consider the tenths’ value of 95.131, which is 1 and less than 5. Therefore, we have to round down: the whole number ones place value of 95.131, 95, remains 95, and the decimal point and all digits (.131) are removed.

95.131 rounded to the nearest whole number = 95

Answer:

95.13 !

Explanation:

Its 131 so its 1 away from 130, which is the closest hundredth. Also, we don't really need the 0, so its 95.13, instead of 95.130!

The equation d= -6t + 10 represents the distance d, in miles, Ralph walks from the library to his house in t hours. His sister, Joan, leaves the library right after Ralph. She rides her bicycle from the library to their house at a constant rate. The equation d = 14t represents Joan's bicycle ride where d, is the distance, in miles, and t is the time, in hours.After how many miles will Joan meet Ralph walking to their house?
A. 2.5 miles
B. 7 miles
C. 18 miles
D. 28 miles

Functions

  • Function Notation

Systems of Linear Equations

  • Solving methods: Substitution/Elimination

Step-by-step explanation:

Step 1: Define

Identify given.

[Ralph's Walking Distance Function]: d = -6t + 10

[Joan's Bicycle Distance Function]: d = 14t

Step 2: Find Meeting Point

To find where Joan and Ralph will meet, we need to find where they intersect. Therefore, we need to find the time which they both meet up at. To do this, we can use the process of substitution to find our value of t:

  1. [Equation 1] Substitute in d:
    \displaystyle\begin{aligned}d = -6t + 10 & \rightarrow 14t = -6t + 10\end{aligned}

From here, we can simply use techniques listed under "Algebra I" to solve for t:

\displaystyle\begin{aligned}14t & = -6t + 10 \n20t & = 10 \nt & = \boxed{ (1)/(2) } \n\end{aligned}

∴ both Joan and Ralph will meet up in half an hour, or 0.5 hours.

Step 3: Find Mileage

To find how many miles they will meet up at, we substitute the number of hours elapsed (found in Step 2) and substitute it into any of the equations given:

\displaystyle\begin{aligned}d & = 14t \n& = 14 \bigg( (1)/(2) \bigg) \n& = \boxed{7} \n\end{aligned}

∴ Joan will meet Ralph after 7 miles.
