acording to pemdas(parenthesis exponents multiplication/division addition/subtraction) we need to do 10 to the power of 4
.
Answer: 9 boys remained in the choir.
Step-by-step explanation:
Let x be the number of of boys and y be the number of girls.
In a school choir, 1/2(half) of the members were girls.
i.e (1)
At the end of the year, 3 boys left the choir, and the ratio of boys to girls became 3:4.
Put y= x from (1), we get
Thus , the number of boys : x= 12
Boys remained in the choir = 12-3=9
20 percent of 70 number is 14.
Here we have to find,
The number of which 20 percent is 14
Le the number = x
Now divide 20 by 100
20% = 20/100
= 0.20
Now multiply 0.20 with x we get,
⇒ 0.20x
Now equate it tp 14 we get,
⇒ 0.20x = 14
⇒ x = 14/0.20
= 70
Hence,
The number is 70.
