Martina read that approximately 10% of all people are left-handed. She wants to design a simulation to approximate the probabili

ty of selecting exactly 2 right-handed people when 3 people are randomly selected.
Martina spins the arrow on the spinner 3 times and records the resulting letters. Martina performs the simulation 30 times. The results of the simulation are shown.

A área de um retângulo é igual a 44, sabendo que as suas medidas são iguais a 4 e (3x+2), calcule a medida do lado maior deste r
jekas [21]

Responda:

11

Explicação passo a passo:

Área do retângulo = comprimento * largura

Dado

Comprimento = 4

Largura = 3x + 2

Área = 44

Substitua na fórmula e obtenha x

44 = 4 (3x + 2)

44 = 12x + 8

12x = 44-8

12x = 36

x = 36/12

x = 3

Obtenha os lados mais longos

Lado mais longo = 3x + 2

Substitua x = 3

Lado mais comprido = 3 (3) + 2

Lado mais comprido = 11

Portanto, a medida do lado mais longo deste retângulo é 11

Find the area of a regular decagon with perimeter 100 units. Show all work.
Slav-nsk [51]
A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.
