Answer:
5/11
Step-by-step explanation:
Probability is the chance that something will happen. Basically, it answers the question of how many times an event will occur in a given number of opportunities.
In this example, the word "GEOMETRICAL" has 11 letters and 5 of them are vowels. They are: E, O, E, I, A. The probability of picking a vowel is 5/11. We could say that there are 5 out of 11 chances of a vowel to occur whenever a piece of paper is taken out of the bag.
Answer:
1/6 of a yard
Step-by-step explanation:
Length of the board = 5/6 yard
He needs to cut the board into 5 equal sections.
Length of each section = length of the board ÷ number of sections
= 5/6 ÷ 5
= 5/6 × 1/5
= (5*1)/(6*5)
= 5/30
= 1/6
Length of each section = 1/6 of a yard
Answer:
8,160 lei
Step-by-step explanation:
<u><em>The question in English is</em></u>
136 children came to the ice rink in the morning, and three times in the afternoon. How much money was collected on the tickets sold, if an entrance ticket costs 15 lei?
step 1
Find the total number of children that came to the ice rink
we know that
The number of children that came to the ice rink in the morning was 136
The number of children that came to the ice rink in the afternoon was (136*3)=408
To find out the total number of children that came to the ice rink , adds the number of children that came in the morning plus the number of children that came in the afternoon
so
step 2
To find out the total money collected, multiply the total number of children by the cost of one ticket entrance
so
Answer:
Step-by-step explanation:
Pythagorean theorem: b² + 6² = 14²
b² = 14² - 36² = 160
b = 4√10
sin(A) = 6/14 = 3/7
∠A = arcsin(3/7) ≈ 25.4°
∠B ≈ 90° - 25.4° = 64.6°
