Find The Measure Of Arc BC

Answers

Answer 1

Answer:

100°

Step-by-step explanation:

is 25% of the circle

Answer 2

Answer:

BC = 100°

Step-by-step explanation:

The chord- chord angle BDC is half the sum of the arcs intercepted by the angle and its vertical angle, that is

[tex]\frac{1}{2}[/tex] ( BC + AE) = 85° ( multiply both sides by 2 to clear the fraction )

BC + AE = 170°

BC + 70° = 170° ( subtract 70° from both sides )

BC = 100°

Answer:  11 goes in the blank in the denominator

The probability as a fraction is 5/11

============================================================

Explanation:

There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.

Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.

Let A = 250 and B = 550.

A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominator

The fraction A/B = 250/550 fully reduces to 5/11.

We can think of it like saying "There are 5 red marbles out of 11 total".

5/11 = 0.4545 = 45.45% approximately

Step-by-step explanation:

Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°

Correct answer: 19cos33°

The values given are 19 (hypotenuse), y (adjacent side), and the angle (33°)

The formula for cosine is adjacent side divided by the hypotenuse

After plugging in the values given into the formula cosx=ad/h, we have:

Cos33°=y/19 Here, we need to isolate the Y

And, the final result is
19Cos33°= Y

So, the correct answer is the letter D

Mr porter had eight parties at her house last year the number of guests at each party is shown below 15,19,9,27,21,21,10,14. What is the median numbers of those parties

The median value is the value at the middle after rearrangement

On rearranging in ascending order

9, 10, 14, (15, 19), 21, 21, 27

Since there are two values in the middle, we will take the average of the numbers

Median = 15+19/2

Median = 34/2

Median = 17

Hence the median value is 17
