Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
Just remember that 100% = 1.00 !
y = .78x
y = 108.5x
y = .946x
Answer:
The scale factor for dilation can be worked out from the ratio of sides.
Here, for i.e, I'H'/IH = (8 + 4)/(4 + 2) = 12/6 = 2
Hope this helps!

Answer:
Falseeeeee
Step-by-step explanation:
Answer:
4.5 inches to the nearest tenth
Step-by-step explanation:
V=4/3πr^3
Divide both sides by 4/3π:
r^3 = V / 4/3π
r = ∛ (V / 4/3 π)
When V = 371 inches:
r = ∛ (371/ 4/3 π)
= 4.46 in
