7 because 42 divided by 6= 7 and length times width = perimeter
The length of the repel line using one of the 3 trigonometry ratios will be 186.78 feet.
<h3>How to calculate the length?</h3>
From the information given, Peyton is walking her dog, Willow, on a local trail and the dog falls 153 feet down a ravine.
The length will be calculated thus:
Cos 35° = 153/AC.
AC = 153/cos 35°
AC = 153/0.819
AC = 186.78 feet.
Therefore, the length is 186.78 feet.

Answer:
A
Step-by-step explanation:
To find the value you can just find 12% of each number (trial and error), until one of them gives you 90 as an answer:
A) 750
750 * 0.12 = 90
B) 1080
1080 * 0.12 = 129.6
C) 360
360 * 0.12 = 43.2
D) 1168
1168 * 0.12 = 140.16
This tells you that 90 is 12% of the 750, and that is why it is your answer
I hope this helps!
The answer is 28 years
At = A0 * e^(-k * t)
At = 12 g
A0 = 15 g
k = 7.9 × 10^-3 = 0.0079
t = ?
12 = 15 * e^(-0.0079 * t)
12/15 = e^(-0.0079 * t)
0.8 = e^(-0.0079 * t)
Logarithm both sides (because ln(e) = 1:
ln(0.8) = ln(e^(-0.0079 * t))
ln(0.8) = (-0.0079 * t) * ln(e)
-0.223 = -0.0079 * t
t = -0.223 / -0.0079
t = 28.23
t ≈ 28 years
Answer:
either D or A i’m not sure
explanation:
your multiplying by 4 each time.
4 x 4 = 16
16 x 4 = 64
64 x 4 = 256
thats for D
your adding 4 each time
19-15=4
15-11=4
11-7=4
7-3=4
that’s for A
