A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134
so
134≤2(L+29) is the inequality
B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft
it's should be 220 because your starting point is at 70 then add 15 for 10 weeks which means you have to add 15*10 or 150 to 70 which will give you 220
Answer:
Denote 3 consecutive numbers as: (n-1), n, (n+1)
=> n - 1 + n + n + 1 = 498
=> 3*n = 498
=> n = 166
=> n + 1 = 166 + 1 = 167
=> 3rd number is 167
Answer:
y = ⅕x; -5
Step-by-step explanation:
y = kx
k = y/x Divided both sides by x
k = 2/10
k = ⅕
y = ⅕x
The equation of variation is y = ⅕x.
If x = -25,
y = ⅕(-25) = -5
Answer:
Area : 114.25 in^2
Perimeter : 47.7 in
Step-by-step explanation:
In this problem when finding the perimeter you have a normal triangle and a semi-circle. so you add the 2 sides of the triangle and find the circumference of a semi-circle with a radius of 5.
17 + 15 + {(3.14)[2(5)]}/2 =
32 + {(3.14)[10]}/2 =
32 + 31.4/2 =
32 + 15.7 =
47.7
When finding the are you have to make the shapes as easy as possible. In this case you divide it to be triangle and semi-circle. Then add the 2 areas together.
[15(10)]/2 + {(3.14)[(5)^2]}/2
150/2 + {(3.14)[25]}/2
75 + 78.5/2
75 + 39.25
114.25
