Answer:

Step-by-step explanation:  sin β = \frac{oposite }{hypotenuse} ; cos β = \frac{Adjacent}{Hypotenuse}

10) sin 32^{0} = \frac{x}{18}

18 sin 32^{0} = x

18 (0.53) = x

<em>x= 9.5 units </em>

cos 32^{0} = \frac{y}{18}

18 cos 32^{0} = y

y = 18 (0.85)

<em>y = 15.3 units </em>

<em></em>

Look at the Schoology problem provided below.
lys-0071 [83]

Answer:

k = 4 units

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

k² + 7.5² = 8.5²

k² + 56.25 = 72.25 ( subtract 56.25 from both sides )

k² = 16 ( take the square root of both sides )

k = \sqrt{16} = 4

Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the rec
Ann [662]

Answer:

Option B is correct that is  amount she is getting per bottle is $0.15  

Step-by-step explanation:

We have been given the information that melisande collected 14 bottles on saturday and 9 bottles on sunday

That means she has collected total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since, she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay one time service fee equation will become

23b -0.25 =3.20

After simplification we will  get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15
