Answer:
The diameter is 6 yards.
Step-by-step explanation:
2pir=18.84
pir=9.42
r=3(nearest whole number)
d=2r
d=2*3
d=6
Therefore, the diameter is 6 yards.
Let the five terms be: a, a + d, a + 2d, a + 3d, a + 4d, then
a + a + d + a + 2d + a + 3d + a + 4d = 5a + 15d = 40
i.e. a + 3d = 8
Also, (a + 2d)(a + 3d)(a + 4d) = 224
(a + 3d - d)(a + 3d)(a + 3d + d) = 224
(8 - d)(8)(8 + d) = 224
(8 - d)(8 + d) = 224/8 = 28
64 - d^2 = 28
d^2 = 64 - 28 = 36
d = sqrt(36) = 6
But a + 3d = 8
a + 3(6) = 8
a = 8 - 18 = -10
Therefore, the term of the sequence is: -10, -10 + 6, -10 + 2(6), -10 + 3(6), -10 + 4(6)
= -10, -4, -10 + 12, -10 + 18, -10 + 24
= -10, -4, 2, 8, 14
Answer:
x= (p+10)/5
Step-by-step explanation:
first you take the peaches and add 10, p+10, and then divide by 5
Tax is 1.54
Including tax = 39.99
Excluding tax= 38.5
Hope this helps
18 for the first the second is 50 and 60
