7 0

Answer:

Step-by-step explanation:

BC = 7 - 3 = 4

AB = 4 - 1 = 3

/AC/² = /AB/² + /BC/²

= 3² + 4²

= 9 + 16

= 25

/AC/ = √25

/AC/ = 5

3(0.3x +1.3) = 2(0.4x -0.85)

Verdich [7]

Answer:

Step-by-step explanation:

3(0.3x + 1.3) = 2(0.4x - 0.85)

0.9x + 3.9 = 0.8x - 1.70

0.9x - 0.8x = - 1.70 - 3.9

0.1x = - 5.6

x = - 5.6 / 0.1

x = - 56

Find the volume of the sphere shown to the right. Give an answer in terms of pi and rounded to the nearest cubic unit.

Vladimir [108]

The correct answers are:
Exact volume = $V = \frac{32}{3} \pi$ in^3
Approximate volume = V = 33.51 in^3

Explanation:

The volume of the sphere is: $V = \frac{4}{3} \pi r^3$

Since r = 2 in

Hence
$V = \frac{4}{3} \pi (2)^3 \\ V = \frac{32}{3} \pi$ in^3 (exact)
V = 33.51 in^3 (approximate)

Look ate the picture down below, and please help me i would really appreciate it

Answer:

46°

Step-by-step explanation:

When secants intersect each other and a circle, the external angle (A) is half the difference of the intercepted arcs:

∠A = (arcDC -arcBC)/2

12° = (arcDC -22°)/2 . . . . . . . fill in the given numbers

24° = arcDC -22° . . . . . . . . . multiply by 2

46° = arcDC . . . . . . . . . . . . . add 22°
