A classmate stated, "A concave polygon be can be regular because it can have all sides congruent." Is this student's claim valid?
Why or why not?

Answers

Answer 1

Answer:

No.

Step-by-step explanation:

A regular polygon has all sides and angles congruent. This is not possible with a concave polygon. If the sides are congruent in a concave polygon the angles  are not congruent.

A rope 24m long is divided into three pieces in a ratio 1:2:5. The length of the shortest piece in
metre is​

Answers

Answer:

3 m

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 5 = 8 parts

Divide the length by 8 to find the value of one part of the rope

24 m ÷ 8 = 3 m ← value of 1 part of the ratio

Thus the shortest piece is 3 m

The required length of the shortest piece is 3 meters.

Given that,
A rope 24m long is divided into three pieces in a ratio of 1:2:5. The length of the shortest piece in meters is​ to be determined.


What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
let the required proportion is equal to x,
then,

x + 2x + 5x = 24
8x = 24
x = 3

Now the lengths
x = 3 meter
2x = 6 meter
5x = 15 meter


Thus, the required length of the shortest piece is 3 meters.

Madjeen jogs around the pond by her house twice a day. In the morning, she jogs $3.5$ laps around the pond. In the evening, she jogs $1$ lap around the pond. Madjeen jogs a total of $5.4$ miles. Write and solve an equation to find out how many miles are in each lap around the pond.

Answers

Answer:

1.2 miles

Step-by-step explanation:

Morning laps = 3.5 laps

Evening laps = 1 lap

Total miles jogged = 5.4 miles

Total laps made = (3. 5 + 1) = 4.5 miles

Number of miles per laps covered :

Total miles jogged / number f lapses hugged around pond.

= 5.4 miles / 4.5

= 1.2 miles

Therefore, number of miles per round around the pond is 1.2 miles

Answer:

I and III

Step-by-step explanation:

How to tell if a triangle is a right triangle with given sides : If a and b are measures of the shorter sides of a triangle, c is the measure of the longest side, and c2 = a2 + b2, then the triangle is a right triangle. If c2 ≠ a2 + b2, then the triangle is not a right triangle. let us see some example problems based on the above concept.

To determine if the triangle is a right triangle, we use the Pythagorean theorem to test or see if the data agrees. We do as follows: c² = a² + b². 10² = (5√3)² + 5². 100 = 75 + 25. 100 = 100. Therefore, the triangle with the given measurements is a right triangle.

21² + 21² = 29²

and

9² + 12² = 15²

Step-by-step explanation:

From the question we are told that:

Dimensions

[tex]AD=4\\BD=6[/tex]

Generally the equation for these similar right triangle is mathematically given by

[tex]\frac{AC}{AB}=\frac{AB}{AD}=\frac{BC}{BD}[/tex]

[tex]\frac{AC}{AB}=\frac{AB}{AD}[/tex]

Where

[tex]AD=x[/tex]

[tex]AC=x+4[/tex]

Therefore

Generally the Pythagoras equation for [tex]\triangle[/tex]ADB is mathematically given by

[tex]AB^2=BD^2+AD^2[/tex]

[tex]x(x+4)=4+x^2[/tex]

Which system of equations has the same solutions as the system below? `3x-y=7` `2x+3y=12`

Answers

Answer:

the system : 9x-3y =21

                   2x+3y = 12

Step-by-step explanation:

hello :

an system of equations has the same solutions as the system below

 the  system  3x-y=7

                     2x+3y=12

for exempl  :  3×(3x-y)=3×7

                     2x+3y)=12

means :

9x-3y =21

2x+3y = 12

6x - 2y = 14, 2x + 3y - 6 = 6 has the same solution as the system of equations 3x - y = 7, 2x + 3y = 12

What are system of equations?

A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

Given system of equations

3x - y = 7........................(1)

2x + 3y = 12...................(2)

Multiply equation 1 with 2

2(3x - y) = 2 × 7

6x - 2y = 14

Subtract 6 from equation 2

2x + 3y - 6 = 12 - 6

2x + 3y - 6 = 6

So, 6x - 2y = 14, 2x + 3y - 6 = 6 has the same solution as 3x - y = 7,

2x + 3y = 12
