Answer:
- The approximate distance between the docks is 357 feet
Step-by-step explanation:
Let the distance between docks be d.
This is the opposite side to 45° angle of triangle with other sides 400 ft and 500 ft.
Use the law of cosines to find the value of d:
(rounded)
Answer:
No of course not
Step-by-step explanation:
For example, the GCF of 8 and 16 is 8. The GCF just has to be the greatest factor of both numbers, it doesn't have to be smaller.
<span>Simplify
0.6n = 84
Solve
By:
Move all terms containing n to the left, all other terms to the right.
Divide each side by '0.6'.
n = 140

So,
</span><span>84 is 60% of 140</span>
Answer:
(7.5)^2 pi
Step-by-step explanation:
Circumference= pi x diameter
area= radius^2 x pi
radius= 1/2 diameter
1. find radius: 15/2= 7.5
2. square radius: (7.5)^2
3. multiply by pi: (7.5)^2 x pi
2(n^2-3)=122
n^2=64
n=+/- 8
When n>0 the value of n is 8
