Find r :
C=2πr
280=2(3.14)r
r=280/2(3.14)
r=44.6cm
find area :
A=πr²
A=3.14(44.6)²
A=6246 cm²
Answer : 4)6,246
The given inequality is 2.5x + 4y ≤ 60. x is the bags of chips and y is the jars of salsa,
Replace x and y in the equation with the possible answers and solve:
A) 10 chips and 2 salsas:
2.5(10) +4(2) = 25 + 8 = 32 This is less than 60 so is a solution.
B) 20 chips, 2 salsas:
2.5(20) + 4(2) = 50 + 8 = 58, this is less than 60 so is a solution.
C) 14 chips, 5 salsas:
2.5(14) + 4(5) = 35 + 20 = 55, this is less than 60 so is a solution.
D) 18 chips , 6 salsas:
2.5(18) + 4(6) = 45 + 24 = 69, this is greater than 60 so is not a solution.
18 bags of chips and 6 jars of salsa is not a solution.
146 minutes in total. One student =3 minutes. So then 42x3= 126. Class picture is 10x2=20. So then add both of them you get 146.
I believe the answer is the last one (D), because if n is 33 than 33 + (33+1[34]) = 67.
