|
Answer» Number of members with BLUE eyes = 140 Percentage of members without blue eyes = 72% To find, The number of members who don't have blue eyes. Solution, We can simply solve this mathematical problem by using the FOLLOWING mathematical process. The percentage of the members who have blue eyes = (100-72) = 28% Now, LET the total number of members = x So, x × 28/100 = 140 x = 140 × 100/28 x = 500 Number of members who don't have blue eyes = (500-140) = 360 Hence, 360 members do not have blue eyes. |

Can anyone say real facts about zombies |
Answer» Hey mate !!Here is ur Answer ⤵️Let's know some interesting facts about Zombies :1. Haitian Clairvius Narcisse is the most famous example of a “real-life” zombie. A voodou ritual combining powerful neurotoxins and hallucinogens puroportedly zombified Narcisse and his tale has been often repeated since. 2. The word “zombie” is thought to have been adapted from the AFRICAN word nzambi meaning 'God'. “Le Grand Zombi,” or the Grand Serpent, was the father of all gods, and appeared in the shape of a python. 3. Zombie fans are called “Zombophiles.” 4. Zombie lore dictates that there are only two WAYS to kill a zombie... go for the brain or cut off the head. 5. “Father of the modern zombie” George A. Romero is viewed as the creator of modern zombie cinema. He has directed more zombie films than anyone in history. 6. Some of the zombie make-up on Romero's seminal 1978 classic Dawn of the Dead was so evocative it made cast members physically sick. 7. Aside from humans, the unassuming ant can also be turned into a zombie. Parasitic fungus Ophiocordyceps can synchronise several ants to chew on a LEAF and then die. The fungus then sprouts through the dead ants’ bodies. 8. A law in Haiti makes it a criminal office to turn someone into a zombie. Article 249 dictates that if someone drugs another person, buries them as though they were dead, and then digs the person up and brings him back to life, it is still considered murder. 9. World Zombie Day takes place around the globe on 8th October. City centres worldwide become infested with the living dead as mass parades take place and raise money for charity. 10. Zombies by their very nature are inconsistent. Hope it helps you ✔️Thank you ❣️@Love hunter Ngt dear.. a small problem between US .... and we r not LOVER's we are Besties forver ☺️ And I hate love |

Find the values of a ,b and c from the given quadratic equation x^2 + 8 x + 15,=0? |
|
Answer» x=-5 or x=-3 Step-by-step explanation: The quadratic formula STATES: For a x 2 + b x + c = 0 , the values of x which are the solutions to the equation are given by: x = − b ± √ b 2 − ( 4 a c ) 2 ⋅ a
Substituting: 1 for a
8 for b
for c gives: x = − 8 ± √ 8 2 − ( 4 ⋅ 1 ⋅ 15 ) 2 ⋅ 1
x = − 8 ± √ 64 − 60 2
x = − 8 − √ 4 2 and x = − 8 + √ 4 2
x = − 8 − 2 2 and x = − 8 + 2 2
x = − 10 2 and x = − 6 2
x = − 5 and x = − 3
The Solution Set Is: x = { − 5 , − 3 } |
