T = T0(r^t)
13.5 = 11.8(r)^99
r^99 = 13.5/11.8 = 1.144
log r^99 = log 1.144
99 log r = log 1.144
log r = log 1.144 / 99 = 0.00059
r = 10^0.00059 = 1.00136
T = 11.8(1.00136)^t
Answer:
6 grapes.
Step-by-step explanation:
If she already had 9 grapes, subtract 15 and 9 to get 6.
Setting is made up of place and time.
The original expression here might be (4x3) + (4x3). This is because the
distributive property simply moves around numbers, but will not change
the value of the equation, as in the question we are looking at here.
Answer:
Step-by-step explanationBy definition we have that the area of a regular octagon is:
A = 4.83L ^ 2
Where, L is the length of the octagon side.
the similarity ratio = the area ratio.
We have then:
similarity ratio = (50) / (18) = 25/9.
the ratio of the perimeters
A1 = 4.83L1 ^ 2
L1 ^ 2 = A1 / 4.83
L2 ^ 2 = A2 / 4.83
L1 ^ 2 / L2 ^ 2 = A1 / A2 = 25/9
L1 / L2 = 5/3
The perimeter is:
P1 = 8L1
P2 = 8L2
P1 / P2 = 8L1 / 8L2 = L1 / L2 = 5/3
answer:
similarity ratio:
25: 9
the ratio of the perimeters:
5: 3
