On a line segment B is between AC and C is between B and D using the segment addition postulate if AB=7 AC=15 AD=32 what does BC BD and CD equal

Answers

Answer 1
Answer:

Answer:

BC = 8

BD = 24

CD = 17

Step-by-step explanation:

First i found that I know AB is 7 and AC is 15 so i realize AB is part of AC so I subtract AB from AC for the difference and got the rest using the same logic

If you dont mind a thx 5 star and brainliest is greatly appreciated trying to hit next level and need 5 more brainliest
Answer 2
Answer: AB+AC=BC
7+15=BC
BC=22

AB+AD=BD
7+32=BD
BD=39

AC+AD=CD
15+32=CD
CD=47

Answer:

The graphical representation of the intervals as well as the solutions of the operation on the number line can be found in the attachment.

A ∪ B = (0, 6) ∪ (12, 24)

C ∩ D = (0, 6) ∩ (14, 24)

Question:

To control the pandemic, people have been restricted from leaving their homes. This measure is called quarantine and is one of the main ways to decrease the number of infections. The exit restrictions that have been taken are the following: o

• A: In Guayaquil, the first week you could not leave home from 12:00 to 6:00.

• B: In the rest of the country, the first week you could not leave home from 8:00 p.m. to 6:00 a.m.

• C: In the whole country, from the third week onwards you cannot leave the house from 2:00 pm to 6:00 am.

• D: If the cases of contagion continue to increase potentially, a 24-hour restriction would be considered. Activities 1. Represent in the form of an interval and on the number line the 4 cases of restrictions posed.

2. Solve the interval corresponding to the following operations: A∪B; C∩D

Step-by-step explanation:

1. The time in Hours is represented on the number line.

A) Restrictions From 12.00pm until 6.00am

In hours: 0 to 6.00am; 12.00pm to 24.00pm

(0, 6); (12, 24)

B. Restriction from 8.00pm to 6.00am

In hours: 20:00pm to 24.00pm; 0 to 6:00 am  

(0, 6); (20, 24)

C. Restriction from 2.00pm to 6.00am

In hours: 14:00pm to 24.00pm; 0 to 6:00am

(0, 6); (14, 24)

D. 24hr restrictions

In hours: 00:00am until 24:00pm

(0, 24)

2. From the graph,

A ∪ B = (0, 6) ∪ (12, 24)

C ∩ D = (0, 6) ∩ (14, 24)

Where '∪' mean the union of A and B. That is, we combine all the element of A and B together.

And '∩' mean the intersection of C and D. That is we pick the values common to C and D.

C.

b = 20 units and h = 9.6 units








D.



b = 20 units and h = 12 units

Answers

 I believe the answer is B. because the dashed line in the middle of your triangle shows the height, and the only side that is perpendicular to the dashed line, is the one b = 20

Olivia runs 15 miles in 3 hours how many miles will she run in 8 hours if she stays the same rate

Answers

Answer:

Olivia will run 40 miles in 8 hours if she maintains the same rate.

Step-by-step explanation:

If Olivia runs 15 miles in 3 hours at a constant rate, we can find her rate of running:

Rate = Distance / Time

Rate = 15 miles / 3 hours

Rate = 5 miles per hour

Now, we can use this rate to calculate how many miles Olivia will run in 8 hours:

Distance = Rate × Time

Distance = 5 miles/hour × 8 hours

Distance = 40 miles

Olivia will run 40 miles in 8 hours if she maintains the same rate.

Answer:

If Olivia stays running at the same rate, She will run 40 miles in 8 hours.

The Drama Club is showing a video of their recent play. The first showing begins at 4:35 p.M. The second showing is scheduled at 7:15 p.M. With a 1 2 −hour break between the showings. How long is the video in hours and minutes? The video is hours and minutes. Complete the explanation of how you can use a number line to find the answer. You can work backward from the start time of the second showing at : . You count back 1 2 hour, which is minutes, for the break between showings to : . The second showing started 20 minutes late. Will the second showing be over by 9:35 p.M.? Complete the explanation why your answer is reasonable. The second showing started at : p.M. The movie lasts hours minutes, so it ends at :45 p.M. So, ? The second showing ? Be over by 9:35 p.M.

Answers

Answer:

Part A

2 hours 10 minutes

Part B;

Please find attached a number line created with MS Visio

Part C

The completed explanation is given as follows

The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m

Step-by-step explanation:

Part A

The given parameters are;

The time the first showing starts, t₁ = 4:35 p.m.

The time the first showing starts, t₂ = 7:15 p.m.

The time interval between shows, t_(interval) = 1/2 hours = 30 minutes

Let 'x' represent the video in minutes, we have;

x = 7:15 - 4:35 - 30 = 2 hours 40 minutes - 30 minutes = 2 hours 10 minutes

The length of the video = 2 hours 10 minutes

Part B;

Using the number line, we have;

1) Plotting the points for the starting and  points for the two showing points which are 4:35 pm. and 7:15 p.m.

2) Plot the point 30 minutes before the start of the second movie which is 6:45 p.m and find the time difference between the start of the first showing and the point 6:45 p.m. which gives the length of the movie which is 2 hours and 10 minutes

3) Given that the second showing starts 20 minutes late, the second showing will start at 7:15 p.m. + 20 min = 7:35 p.m.

4) The second showing ends at 7:35 p.m. + 2 hours 10 minutes = 9:45 p.m.

Therefore, the second showing will be over 9:35 p.m.

Part C

The second showing starts at 7:35 p.m. The movie lasts 2 hours 10 minutes so it ends 9:45 p.m. So the second sowing be over by 9:45 p.m.
