Answer:

∠ CDB = 43°

Step-by-step explanation:

Angles subtended at the circumference by the same arc are congruent.

The arc CB subtends both ∠ CAB and ∠ CDB , thus

∠ CDB = ∠ CAB = 43°

Answer:

Number of points need = 6 points

Step-by-step explanation:

Given:

New average = 5

Points peter has = 44

Total quiz play = 9

Find:

Points required for average of 5

Computation:

Total number of match = 9 + 1

Total number of match = 10

Average points = 5

Assume;

Number of points need = x

So,

Average points = [Total points] / Total number of match

5 = [44+x] / 10

50 = 44 + x

x = 6

Number of points need = 6 points

The score does Peter needs on his tenth and final quiz in order to have a final quiz average of 5 is 6 and this can be determined by using the formula of average.

Given :

Peter scored a total of 44 points on 9 math quizzes.

The following steps can be used in order to determine the score of the tenth quiz:

Step 1 - The formula of average can be used in order to determine the score of the tenth quiz.

Step 2 - According to the given data, Peter scored a total of 44 points on 9 math quizzes. Now, let the score of the final tenth quiz be 'x'.

Step 3 - The average of the 10 quizzes is given by:

[tex]\dfrac{44 + x }{10}=5[/tex]

Step 4 - Simplify the above expression in order to determine the value of 'x'.

50 = 44 + x

x = 6

Answer:

The answer is 50 degrees

Step-by-step explanation:

The small box at the corner of the triangle indicates that the triangle is exactly 90 degrees, or a right angle. In order to solve the expression, you would need to do 40 + x = 90, which would be x = 50

Answer:

It should be 40 degrees, If you have a protractor, you could measure it.

Step-by-step explanation:

I think it's 40 degrees because if you fold it in half, it would probably match.

I had this on my test and got it right

Answer:

m∠MON = 15°

Step-by-step explanation:

The given parameters are;

m∠LON = 77°

m∠LOM = 9·x + 44°

m∠MON = 6·x + 3°

By angle addition postulate, we have;

m∠LON = m∠LOM + m∠MON

Therefore, by substituting the known values, we have;

∴ 77° = 9·x + 44° + 6·x + 3°

77° = 9·x + 44° + 6·x + 3° = 15·x + 47°

77° = 15·x + 47°

77° - 47° = 15·x

15·x = 77° - 47° = 30°

15·x = 30°

x = 30°/15 = 2°

x = 2°

Given that m∠MON = 6·x + 3° and x = 2°, we have;

m∠MON = 6 × 2° + 3° = 12° + 3° = 15°

m∠MON = 15°.

275 divided by 32 in equal to 8.59, so you just have to round up  but that last trip just wont be full

Answer:

9 roller coaster rides. hope this helps!

Step-by-step explanation:

A roller coaster can hold 32 people at a time.

there are 275 people waiting in line.

How many trips will it take for there to be 0 people waiting in line?

We know the roller coaster can hold 32 people at a time, and 275 people are waiting in line.

275/32=8 rides and 19 people left.

If you don't know how to do that: 275 people at first. 275-32 because the roller coaster can only hold 32. Repeat that process untill you find your answer.    

So we have 8 rides, and 19 people left? It doesn't matter, It will not take, half the time left, or more time to get it done. So anything below or equal to 32 people will take the same amount of time. So our final answer is 9 rides. Not 8.59375.
