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.

divide both sides by </span><span>√3.
x=20/(</span><span><span>√3)

In a pile of 55 coins made of nickels and dimes totaling $3.90 how many of each coin are there
tigry1 [53]
There are 5 pennies in a nickel, and 10 pennies in a dime.  Now in $3.90 there are 390 pennies.

n = number of nickels in the pile

d = number of dimes in the pile

we know the pile has 55 coins, therefore whatever "n" and "d" are, we know that n + d = 55.

now, "n" is how many nickel coins are there, how many pennies is it in total?  well, 5 pennies to a nickel, for "n" nickels, will then be 5(n) or 5n.

and "d" is how many dime coins are there, so therefore in "d" coins, there are 10(d) pennies, or 10d.

we also know the total amount of pennies is 390, therefore 5n + 10d = 390.

\bf \begin{cases}&#10;n+d=55\implies \boxed{n}=55-d\\&#10;5n+10d=390\\&#10;-------------\\&#10;5\left(\boxed{55-d}  \right)+10d=390&#10;\end{cases}&#10;\\\\\\&#10;275-5d+10d=390\implies 5d=115\implies d=\cfrac{115}{5}\implies d=23

how many nickel coins are there anyway?  well, n = 55 - d.

Can anybody help me on this?
Eduardwww [97]

Answer: second option.

Step-by-step explanation:

You need to descompose the radicand 8 and the radicand 50 into their prime factors:

8=2*2*2=2^2*2\\50=2*5*5=2*5^2

Then you can rewrite the expression:

\sqrt{8}+\sqrt{50}

=\sqrt{2^2*2}+\sqrt{2*5^2}

Since:

\sqrt{a^2}=a

You can simplify the expression:

=2\sqrt{2}+5\sqrt{2}

As the indices and the radicands are the same, you can make the addition:

=7\sqrt{2}
