Domain x|x = -2, 2
range x|x = -1, 4
Answer:
60 <u>and</u> 30
Step-by-step explanation:
Plug in each number into cos(θ) until your answer is 0.5 since sin(θ) is equal to 0.5.
sin(-30)=-0.5
sin(30)=0.5
sin(60)=0.5
sin(180)=0
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dollars.
No of coins Sparrow had in the beginning 92 coins
Step-by-step explanation:
Total coins = 210
Current ratio = 4:5:6
It implies 210 needs to be split into 15 parts (4+5+6)
So, each part = 210/15 = 14 coins
Again which implies 14*4 : 14*5 : 14*6 = 56 : 70 : 84
So before the game began,
No of coins Ahab had = (56 - 5) = 51
No of coins Davy had = (84 - 7) = 67
Hence, No of coins Sparrow had = (210 - 51 - 67) = 92 coins
