Answer:

Step-by-step explanation:

This problem does not specify what the radius of the circle is, and so we will have to represent that by r.

Arc length = s = rФ, where Ф is the central angle in radians.

Converting 162° into radians:

162° 1 rad

------- · ------------ = 0.9 rad

1 180°

Then the arc length BC is s = rФ, or r(0.9 rad)

If, for example, r = 10 m, then the arc length would be (10)(0.9) m = 9 m

Employees at Company A earn 4% commission on sales. Employees at Company B earl 2/3 of what Company A employees earn. How much w

alexira [117]

First let's see how much commission an employee would get by earning 13595 at Company A:

$(13595)\cdot(0.04)=543.80$

Since employees at Company B earn 2/3 of what Company A employees earn, we would have:

$(543.80)\cdot\frac{2}{3}=\frac{543.80\cdot2}{3}=362.53$

Therefore, a Company B employee would earn $362.53 on $13595

The values of x and y vary directly

Rama09 [41]

Answer:

y = - $\frac{3}{2}$ x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 4, y = 6, thus

k = $\frac{y}{x}$ = $\frac{6}{-4}$ = - $\frac{3}{2}$

y = - $\frac{3}{2}$ x ← equation of variation
