It is 7, i am pretty sure.
Y-(-7)=-9(x-6)
Y+7= -9x+54
Subtract 7 from both sides
Y= -9x+47
Volume of cone= 1/3 πr²*h
15²=10²+h²
h²=15²-10²=125
h=√125
Volume of cone= 1/3 *π*100*√125=π/3*(100*5√5)=500π√5/3
Volume of sphere=4/3*π*r³=4/3*π*1000=4000π/3
Volume of half sphere=(4000π/3)/2=2000π/3
All Volume=500π√5/3+2000π/3
Answer:Marks below 75%
Step-by-step explanation:
Since the pass marks is 75%,the fail marks should be Marks below 75%
46% is equal to 14/25
14/25 is equal to 46/100 (multiply 14/25 times 4/4) and that is 46%
