There is no good answer for this.

You would do s/12, since there is 1 adult for every 12 kids. Then, round the number to the nearest 1. (if it is a decimal, there is a number and remainder of students.)

Esta é a trigonometria . Se você desenhar uma linha a partir do topo da casa de luz para o barco, você terá a hypotonuse de um triângulo. Um truque é lembrar que este é um triângulo especial. É um triângulo 30-60-90 , que tem propriedades especiais mostradas na fixação abaixo . por isso sabemos que o lado adjacente que não é o hyposonuse é x√3 . Agora sabemos que x<span>√3 = 20
Solve for x.
x</span><span>√3=20
divide both sides by </span><span>√3.
x=20/(</span><span><span>√3)
</span>Try not to have square roots (</span><span><span>√)</span> in denomenator so multiply top and bottom by </span><span>√3 and get

x is what we are looking for so the answer is </span>

Alekssandra [29.7K]
<span>We write the equation in the standard form which is:

ax^2 + bx + c = 0

(x + 15)(x) = 100
x^2 + 15x - 100 = 0
(x + 20) (x-5) = 0

The solutions are

x = -20 and x = 5

Therefore, the correct answer is option B. </span><span>The solution x = 5 should be kept, but x = –20 is unreasonable.</span><span>

Answer:

6 times the square root 2

Step-by-step explanation:

Hi there!

Since this is a 45-45-90 triangle, we know the sides are a, a, and a times the square root of two.

Since we can see the 6 is on of the sides that has the 90 degree corner, we know that 6 is our a.

Therefore, we know k is the hypotenuse and is 6 times the square root 2.

Hope this helped, have a great day! ^u^
