The total number of students in the maths club is 40
the number of boys is 5 less than 2 times the amount of girls
to find the number of girls and boys let the number of girls be X.
so 2X-5= the number of boy
so, X+ 2X-5=40
3X-5=40
3X=40+5
3X=45
X=45/3
X=15
the number of girls is 15
and the number of boys is 15x2-5=25 boys
Non existent that is your answer thank you
A = pi r^2
A = 3.14 x 7^2
A = 3.14 x 49
A = 153.86

Answer:
INCORRECT
Step-by-step explanation:
Given a rectangular prism,
Total Surface Area = 2(LW+LH+WH)
If Length = 12, Width =20, and; Height = 16.
Total Surface Area = 2(12*20+12*16+20*16)
=2(240+192+320)
=2(752)
=1504
The Surface Area is 1504 Square Units, therefore if someone says the surface Area is 3,840, they are incorrect!
