Answer:

Step-by-step explanation:

w+13- $\frac{2w}{3}$ =16

w · $\frac{3}{3}$ - $\frac{2w}{3}$ +13=16

$\frac{w}{3}$ +13=16

$\frac{w}{3}$ =3

w=9

Find the value of each variable

4vir4ik [10]

Answer:

x = 10 $\sqrt{2}$ , y = 10 $\sqrt{6}$

Step-by-step explanation:

using the sine and cosine ratios in the right triangle and the exact values

cos60° = $\frac{1}{2}$ , sin60° = $\frac{\sqrt{3} }{2}$ , then

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{20\sqrt{2} }$ = $\frac{1}{2}$ ( cross- multiply )

2x = 20 $\sqrt{2}$ ( divide both sides by 2 )

x = 10 $\sqrt{2}$

and

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{20\sqrt{2} }$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2y = 20 $\sqrt{2}$ × $\sqrt{3}$ = 20 $\sqrt{6}$ ( divide both sides by 2 )

y = 10 $\sqrt{6}$

3 coins are tossed and two six-sided dice are rolled. What is the probability of getting an even number in the dice

salantis [7]

<span>3 coins are tossed and 3 six sided dice are rolled.what is the probability of getting 3 heads and an even number on a dice
-----
P(3 heads) = 1/8
P(even #) = 1/2

======
P(3 heads AND even #) = (1/8)(1/2) = 1/16
