If it's a geometric sequence then:
We calculate the fourth and fifth term of the sequence:
Answer:
In year 4 15.1875 animals.
In year 5 11.390625 animals.
Answer:
Step-by-step explanation:
xy=-30
y=-30/x
x+y=-4
x-30/x=-4
x²-30=-4x
x²+4x-30=0
Answer:
-0.03571428571
Step-by-step explanation:
Answer:
cylinder = 27π
cone = 9π
sphere = 36π
Step-by-step explanation:
volume of a cylinder = πr²h where r = radius and h = height
height of cylinder (h) = 3 and radius (r) = 3
so volume = π(3)²3
==> simplify exponent
volume = π9(3)
==> multiply 9 and 3
volume of cylinder = 27π
Volume of a cone = πr²(h/3) where r = radius and h = height
height of cone (h) = 3 and radius (r) = 3
so volume = π(3)²(3/3)
==> simplify exponent
volume = π9(3/3)
==> divide 3 by 3
volume = π9(1)
==> multiply 9 and 1
volume of cone = 9π
volume of a sphere = 4/3πr³ where r = radius
radius = 3
so volume = 4/3π(3)³
==> simplify exponent
volume = 4/3π27
==> multiply 4/3 and 27
volume of sphere = 36π
We'll do it in cents and convert when we have to.
Tanya paid x per item, a total of 4x.
Tony paid x-125 per item (in cents) for a total of 5(x-125)
4x = 5(x-125)
4x = 5x - 625
x = 625 = $6.25
Check:
4(625) = 2500
5(625-125)=2500, same, checks
Answer: Tanya paid $6.25 per item, Tony $5.00 per item
