The answer would be A. -0.86 because if you plug in -0.86 for r then add -0.86 and 0.27 then you would get the correct answer which would be -0.58. :)

You subtract 0.27 from both sides
r=-0.59-.27
.59-.27=-.86
R=-0.86
The answer is A

Answer:

<em>The total cost is $850</em>

Step-by-step explanation:

From the function

C = 2T + 250

where

T is the number of T-shirts they purchase.

If the the shop purchases 300 T-shirts, then it means

T = 300

substituting into the function, we have

C = 2(300) + 250

C = 600 + 250

c = <em>$850</em>

What is the length of the arc shown in red?

professor190 [17]

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

arc = 2πr × $\frac{60}{360}$

= 2π × 18 × $\frac{1}{6}$

= 36π × $\frac{1}{6}$

= 6π ≈ 18.8 cm ( to 1 dec. place )
