So burger king offers 10 chicken nuggets for $1.49

1 chicken nugget = price for 10 chicken nugget / 10 chicken nugget

= $1.49 / 10 = $0.15 per nugget (approximated)

Hope that helps!

What is the definition of csc θ ?

docker41 [41]

<span>The trigonometric function cosecant is written as csc θ. For acute angles, csc θ can be found by the SOHCAHTOA definition, shown below on the left. The circle definition, a generalization of SOHCAHTOA, is shown below on the right. f(x) = csc x is a periodic function with period 2π.</span>

How much water conditioner for 2.5 gallon tank?

vivado [14]

If i'm correct you should add 0.5 mL to your 1 gallon tank, and I would say about 1.25 mL to your 2.5 gallon. It will not be extreme if you end up putting a little more in than you are supposed to. I'm not 100% because i haven't slept so my brain is being slow.

Cos (-Ø)= √3/3 sinØ <0 what is the value of sinØ?

Inga [223]

Answer:

sin∅= - √6/3

Step-by-step explanation:

Trigonometric function cos is even function which mean:

cos (-∅) = cos ∅

Trigonometric function sin is odd function which mean:

sin (-∅) = - sin∅ => sin∅ < 0

The basic trigonometric equation reads in this case with angle marked ∅:

sin²∅ + cos²∅ = 1 => sin²∅ = 1 - cos²∅ => sin²∅ = 1 - ( √3/3 )² =>

sin²∅ = 1 - (3/9) => sin²∅ = 1 - (1/3) = (3/3) - (1/3) = 2/3 => sin∅ = - √(2/3) =>

sin∅ = - √2/√3 => sin∅ = - √6/3

God with you!!!

Need help please on geometry

zimovet [89]

To solve this we are going to use the formula for the area of a circle: $A= \frac{1}{4} \pi d^2$
where
$A$ is the area of the circle
$d$ is the diameter of the circle

We know from our problem that the area of our circle is 10 inches long, so $d=10in$ . Lets replace that value in our formula to find $A$ :
$A=\frac{1}{4} \pi (10in)^2$
$A=78.54in^2$

We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.
