Answer:

A

Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse) , so

x² = 4 × (4 + 8) = 4 × 12 = 48 ( take square root of both sides )

x = \sqrt{48} = \sqrt{16(3)} = 4\sqrt{3} → A

Answer:

Step-by-step explanation:

Dado que:

Um técnico em eletricidade recebeu um pacote que continha 12 chaves não identificadas, a probabilidade de que ele acertasse na primeira vez será:

= número de ensaios / número total de ensaios disponíveis

O técnico eletricista tem apenas uma tentativa

uma vez que existem 12 chaves não identificadas, o número total de testes disponíveis 12

∴

= 1/12

= 0.0833

= 0.0833 × 100

= 8.33%

4m-3n=8; solve for m
Ierofanga [76]
4m - 3n = 8

Add 3n to both sides.

4m = 3n + 8

Divide both sides by 4.

m = 3/4n + 2

So, m = 3/4n + 2

However, if you made a typo, and meant 3m instead of 3n, your answer would be :

4m - 3n = 8

n = 8

~Hope I helped!~
