Answer:

x = 23, y = 20

Step-by-step explanation:

The angle which contains x is equal to the angle 120°, so you can do an equality:

5x +5 = 120

5x = 120 -5

5x = 115

x = 115/5

x = 23°

3y + 120° in this case is equal to 180, so:

3y + 120 = 180

3y = 180 - 120

3y = 60

y = 60/3

y = 20

Y is inversely proportional to the square of (x + 2).<br>When x = 3, y = 2.<br>Find y when x = 8.​
VikaD [51]

Answer:

y = k/(x+2) squared

substitute y and x to find the value of k.

k =50

nxt used the value of k with same formula:.

y= 50/ (8+2) squared

y =1/2

Answer 10 only please, explain how you got your answer
ira [324]

Question:

The circumference of a clock is 22 inches. What is the radius of the clock?

Answer:

Radius = 3.5 inches

Solution:

Shape of the clock is circle.

Circumference of the circle = 2πr

Circumference of a clock = 22 inches

\Rightarrow2\pi r=22

$\Rightarrow2\times\frac{22}{7}\times  r=22

$\Rightarrow\frac{44}{7}\times  r=22

$\Rightarrow  r=22\times \frac{7}{44}

$\Rightarrow  r=\frac{7}{2}

⇒ r = 3.5 inches

Hence the radius of the clock is 3.5 inches.

PLEASE HELPPPPP!!!!!!!!! (show work if you can)
Kryger [21]

Answer:

180x^4y^3z^2

Step-by-step explanation:

Start by finding the LCM of the coefficients of each polynomial:

LCM(12,18,30)=180

Next, to find the least common multiple of each of the following terms, we need to take the absolute minimum we can of each term (x, y, and z). The largest term of x is x^4 in the first polynomial, so we'll take exactly that for our x term in the LCM, absolutely nothing more. Similarly, the largest term of y in any of the three polynomials is y^3 (also in the first polynomial) and the largest z term in any of the three polynomials is z^2 in the second polynomial. Thus, the LCM of all our polynomials is:

180\cdot x^4\cdot y^3\cdot z^2=\boxed{180x^4y^3z^2}
