a - side of the square

4a - the perimeter of a square

76 in - the perimeter of a square

The equation:

4a = 76     <em>divide both sides by 4</em>

a = 19 in.

<h3>Answer: Each side has length 19 inches.</h3>

Answer:

m∠N = 85°

Step-by-step explanation:

<u>Properties of a parallelogram</u>

  • opposite sides are parallel and equal in length
  • opposite angles are equal
  • interior angles that lie on the same side of the transversal are supplementary - their sum is 180°

Therefore,

m∠M + m∠N = 180°

⇒ 95° + m∠N = 180°

⇒ m∠N = 180° - 95°

⇒ m∠N = 85°

--------------------------------------------------------------------------------------

<u>Additional calculations</u>

m∠M = m∠P = 95°

m∠N = m∠L = 85°

MN = LP

ML = NP

An ant went 2 meters away from its nest searching for food. The next time, the ant went 3 meters away. Each successive time the
seropon [69]

Answer:

The first time, the ant went 2m away, then we have a₁ = 2m

The second time, the ant went 3m away, then we have a₂ = 3m

The next time, the ant went a distance equal to the sum of the two previous ones, so we can write it in a general case as:

aₙ = aₙ₋₁ + aₙ₋₂

Only if n > 2.

then the third time, we have n = 3.

a₃ = a₂ + a₁ = 2m + 3m = 5m

a₄ = a₃ + a₂ = 3m + 5m = 8m

a₅ = a₄ + a₃ = 5m + 8m = 13m

This means that in the fifth trip, the ant went 13 meters away from its nest.

And if we consider the fact that the ant must go and return, then it will move a total distance of 13 meters two times, or 2*13m = 26 meters.

La un concurs de matematica se dau 40 de probleme. Pentr fiecare raspuns corect se acorda 7 puncte, iar pentru fiecare raspuns g
Ratling [72]

Answer:

a primit 36 ​​corect ane 4 în mod greșit

Step-by-step explanation:

În această întrebare, ne preocupăm să calculăm numărul de răspunsuri corecte și de răspunsuri greșite pe care elevul le-a dat.

În primul rând, începem prin atribuirea de variabile.

Numărul de răspunsuri corecte să fie x în timp ce numărul de răspunsuri greșite să fie y

Deoarece există 40 de probleme în total, aceasta înseamnă că adăugarea ambelor este egală cu 40 matematic,

x + y = 40. ••• (i)

Acum să trecem la partea complicată. Fiecare răspuns corect = +7. Răspunsul corect total este astfel + 7x Fiecare răspuns greșit este = -5. Răspunsul total greșit este astfel -5y Punct total marcat = 232 Aceasta

înseamnă că; 7x -5y = 232 ••••••••• (ii)

De la i, putem spune y = 40 -x să punem acest lucru în ecuație

ii 7x -5 (40-x) = 232

7x - 200 + 5x = 232

12x = 232 + 200 12x = 432 x = 432/12 x = 36 Deoarece y = 40 - x y = 40 - 36 y = 4
