Answer: The trick to this question is twofold:
Spot that 94 is double 47. Therefore when going downstream, the speed of the boat relative to the earth is double it's speed going upstream as it covers double the distance in the same time.
Understand that whatever the speed of the boat is, when going downstream it's speed relative to the earth is 6mph greater than speed relative to the water, and conversely when going upstream, earth speed is 6mph less than water speed.
So, if the speed through the water is X, upstream speed is (X-6) and downstream speed is (X+6).
Now, we know that upstream speed is double downstream speed, so:
Double (x-6) is equal to (X+6)
Or:
2(x-6)=(X+6)
Answer:
480 miles
Step-by-step explanation:
*please stop titling your questions as: “Help help help help help help help help help help help plsss” thank you*
120/1.5 = 80
80 x 6 = 480
It can travel 480 miles in 6 hrs.
How far is the kicker from the right post, to the nearest yard is: 23 yards.
<h3>Distance</h3>
Using sine theorem
Let y represent the numbers of yards
Left triangle=3/sinx=14/sin∝
Right triangle=5/sinx=y/sin(180-∝°)
sin∝°=sin(180-∝°)
Hence,
3/5=14/y
y=5×14/3
y=23 yards
Therefore how far is the kicker from the right post, to the nearest yard is: 23 yards.

Coordinates of center and radius of circle is 
.
<u>Step-by-step explanation:</u>
Here we have , The equation of a circle is given below.
(2 – 13.4)2 + (y + 2.6)2 = 100 or , 
We know that , Equation of circle is given by :
⇒ 
...........(1)
where (h,k) are the coordinates of center of circle and r is the radius of circle . Let's simplify given equation of circle in question ;
⇒
⇒ 
⇒ 
Comparing this equation to (1) we get :
Therefore , Coordinates of center and radius of circle is .
