First calculate that numeric value. It cannot be done immediately without calculations.
if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.
Those 15% are 30 that were given in text. Now we can calculate this using proportion:
15% 30 students
85% x students
we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170
Answer is 170
Answer:
Step-by-step explanation:
The bottom leg is divided into equal segments, one of them is b.
It means the bottom leg is b + b = 2b.
<u>According to Pythagorean:</u>
<u>Solve for b:</u>
- 1681 = 4b² + 81
- 4b² = 1681 - 81
- 4b² = 1600
- b² = 400
- b = √400
- b = 20 cm
The correct answer is option B which is 3
<h3>
What is mean?</h3>
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
Given data:-
4,3,2
The mean will be calculated as:-
Mean = (4 + 3 + 2) / 3
Mean = 9 / 3
Mean = 3
Therefore the correct answer is option B which is 3

Answer:
As shown in picture, AC is tangent to circle O
=> angle BAC = 90 deg
As the property of angle on circle:
=> BAY = (1/2) arc BY = (1/2) x 52 = 26 deg
=> angle YAC = angle BAC - angle BAY = 90 - 26 = 64 deg
Hope this helps!
