Alright, lets get started.
Suppose total number of dancers in school = x
We have given in question, 42 % of total dancers are ballet dancers.
So, we could find number of ballet dancers by finding 42 % of total dancers.
Number of ballet dancers = x * 42 %
Number of ballet dancers = x * 42/100 = 0.42 x
As per given in question, there are 63 ballet dancers in school.
Which means 0.42 x = 63
Dividing 0.42 from both sides
0.42 x / 0.42 = 63 / 0.42
x = 150
Hence number of total dancers in school = 150 : Answer
Hope it will help :)
-4+x=9.5
x=13.5
The student might have subtracted 9.5-4, which results in the answer 5.5. The correct answer is 13.5.
Answer:
(a+3)^3
a^3 + b^3 + 3ab [identity : (a+b)^3 )]
a^3+ 3^3 + 3×a×3
a^3 +27+9a
answer : a^3+27+9a
hope it helps you
mrk me braniliest plz
The probability of getting a red cube is 3:5 the probability of getting a blue cube is 2:5
Solution:
The Quadratic polynomial in variable x is :
→ 6 x² + x -7
Breaking the middle term i.e term containing variable x
= 6 x² + 7 x - 6 x -7
= x ( 6 x +7) - 1 (6 x +7)
= (6 x + 7)(x-1)→→→Factor of 6 x² + x -7
