Answer:
135 seats
Step-by-step explanation:
Let number of balcony seats = y
Let number of lawn seats = x
x+20=y --- (i)
x+y=250 --- (ii)
Substituting for Y in (ii)
2x+20=250
x=115 seats (Lawn)
y= 135 seats (Balcony)
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:
(B)5200
Step-by-step explanation:
Since the value was increased by 30%, the new value in the options is 130% of the initial Value.
Let x be the number of hex nuts in the bin before that delivery.
130% of x = New Value
![\frac{130}{100} \: of\: x =New \: Value](https://tex.z-dn.net/?f=%5Cfrac%7B130%7D%7B100%7D%20%5C%3A%20of%5C%3A%20x%20%3DNew%20%5C%3A%20Value)
1.3 of x = New Value
x= New Value ÷ 1.3
Since the number of hex nuts in the bin is a whole number, we test the options to see which satisfies this condition.
- 5100 ÷ 1.3 =3923.08
- 5200 ÷ 1.3=4000
- 5400÷ 1.3=4153.85
- 5500÷ 1.3=4230.77
- 5600÷ 1.3=4307.69
5200 is the only option which satisfies our stated condition.
