In math problems, "of" usually means "multiplied by."

(owed to sister) = 0.2*(earnings)
.. = 0.2*$324.65

Rhoads owes her sister $64.93.

Answer:

The measure of arc ABC is 180 + x ⇒ 1st answer

Step-by-step explanation:

Let us revise some notes about the arcs of a circle

  • The measure of an inscribed angle is half the measure of its subtended arc
  • The measure of the central angle is equal to the measure of its subtended arc
  • If two tangents intersect outside a circle then the measure of the angle formed between them is one-half the positive difference of the measures of the intercepted arcs

∵ CD and AD are two tangents to the given circle

∵ They intersected at point D out side the circle

∵ The measure of ∠ADC = x°

- By using the 3rd note above

∵ The intercepted arcs are arc ABC and arc AC

∴ x° = \frac{1}{2} (measure of arc ABC - measure of arc AC)

- Multiply both sides by 2

∴ 2 x = (measure of arc ABC - measure of arc AC)

- Add measure of arc AC in both sides

∴ 2 x + measure of arc AC = measure of arc ABC ⇒ (1)

∵ The measure of a circle is 360°

∵ The arcs ARC and AC is formed the circle

∴ Measure of arc ABC + measure of arc AC = 360°

- Subtract measure of arc ABC from both sides

∵ Measure of arc AC = 360 - measure of arc ABC ⇒ (2)

- Substitute (2) in (1)

∴ 2 x + 360 - measure of arc ABC = measure of arc ABC

- Add measure of arc ABC to both sides

∴ 2 x + 360 = 2 measure of arc ABC

- Divide both sides by 2

∴ x + 180 = measure of arc ABC

∴ The measure of arc ABC is 180 + x

a bag contains 5 red marbles, 3 yellow marbles, and 2 blue marbles. Once a marble is drawn, it is not replaced.what is the proba
Aleksandr-060686 [28]
5 red, 3 yellow, and 2 blue....for a total of 10 marbles

P(first one being blue) = 2/10 which reduces to 1/5
not replaced
P(second one is blue) = 1/9...because u already pick a blue, meaning there is only 1 left, and there is one less marble, so there is a total of 9 marbles.

P(both events happening) = 1/5 * 1/9 = 1/45 <==
