<u>Given</u>:

Given that R is a circle.

The length of BC is 5 units.

The length of CE is 12 units.

We need to determine the lengths of AC and CD.

<u>Length of the chord AD:</u>

The lengths of the segments AC and CD can be determined using the intersecting chords theorem.

Applying the theorem, we have;

AC \cdot CD=BC \cdot CE

Substituting the values, we have;

AC \cdot CD=5 \times 12

AC \cdot CD=60

Hence, when multiplying the two segments AC and CD, we get 60 units.

Thus, the length of the chord AD is 60 units.

<u>Option F</u>: 6 and 10

The possible lengths of AC and CD can be determined by multiplying the two segments.

Thus, we have;

AD=AC \cdot CD

Substituting the values, we have;

60=6 \times 10

60=60

Thus, the possible lengths of AC and CD are 6 and 10 respectively.

Hence, Option F is the correct answer.

<u>Option G</u>: 8 and 9

Similarly, we have;

AD=AC \cdot CD

Substituting the values, we have;

60=8 \times 9

60 \neq 72

Since, both sides of the equation are not equal, Option G is not the correct answer.

<u>Option H</u>: 7 and 14

Similarly, we have;

AD=AC \cdot CD

Substituting the values, we have;

60=7 \times 14

60 \neq 98

Since, both sides of the equation are not equal, Option H is not the correct answer.

<u>Option J:</u> 12 and 13

Similarly, we have;

AD=AC \cdot CD

Substituting the values, we have;

60=12 \times 13

60 \neq 156

Since, both sides of the equation are not equal, Option J is not the correct answer.

Therefore, the possible lengths for segments AC and CD are 6 and 10 respectively.

Hence, Option F is the correct answer.

Answer:

F) 6 and 10

Step-by-step explanation:

AC > BC

AC > 5

CD < CE

CD < 1

Also,

AC × CD = BC × CE

AC × CD = 5 × 12 = 60

6 × 10 = 60

Answer:

  B, C

Step-by-step explanation:

Shelby's total earnings will be the sum of the amount she has earned and the amount she can earn working h hours. That latter amount is 25h, since she makes $25 per hour. She wants that total to be at least $2000.

  75 + 25h ≥ 2000

Dividing by 25 gives ...

  3 +h ≥ 80

subtracting 3, we have ...

  h ≥ 77

These match options B and C of your list.
