Answer:

radius = 4

Step-by-step explanation:

Recall that the equation of a circle centered at (0,0) on the plane is given by the formula:

x^2+y^2=r^2

where "r" is the radius of the circle.

S, in our case, since the equation reads:

x^2+y^2=16

16 corresponds to the square of the circle's radius. Therefore the radius can be found via:

r^2=16\\r=+/-\sqrt{16\\}\\r=+/-4

and since we are talking about the length of a radius, we choose the positive option for the answer: radius = 4

Answer:

length = 48 feet , width = 32 feet

Step-by-step explanation:

Using

2W + 2L = 160 with W = L - 16 , then

2(L - 16) + 2L = 160 ← distribute and simplify left side

2L - 32 + 2L = 160

4L - 32 = 160 ( add 32 to both sides )

4L = 192 ( divide both sides by 4 )

L = 48

Substitute L = 48 into W = L - 16

W = 48 - 16 = 32

Thus length = 48 feet and width = 32 feet

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
sergiy2304 [10]

Answer:

The measure of angle θ is 7π/6. The measure of its reference angle is  <u>210°</u>

and sin θ is​ <u>-1/2</u>.

Step-by-step explanation:

The correct question is:

<em>The measure of angle θ is 7π/6. The measure of its reference angle is  ___</em>

<em>and sin θ is​ ___</em>

180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:

180° / π radians = x° / (7π/6 radians)

x = (180/π) * (7π/6 radians)

x = 210°

And sin(210°) = -1/2

The density of a fish tank is 0.3 fish over feet cubed. There are 15 fish in the tank. What is the volume of the tank?
ale4655 [162]
Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given -  (making that a total of 15 grams), 

D = m / v
0.3 = 15 / v 
v = 15 / 0.3 = 50 ft cubed

Hope this answers your question correctly :)

What are the Multiples of 24
Mademuasel [1]
You just have to take your multiplication table and then you can find what multiplication make 24
6x4=24
2x12=24
3x8=24

So 2 3 4 6 8 12 are all the multiples of 24
