Answer:
What kind?
Step-by-step explanation:
Answer:
30 miles
Step-by-step explanation:
We know
D = RT
Where
D is the distance
R is the rate
T is the time
<u>Towards Island:</u>
R = 15
Let time be x
So, we can write:
D = 15x
<u>Return from Island:</u>
R = 10
Let time be y
So, we can write:
D = 10y
Also, total time is 5 hours, so we can write:
x + y = 5 [equation 2]
Now, since the distance for both legs of the journey is equal, we can write:
Distance 1 = Distance 2
15x = 10y
Now we replace this equation with equation 2, so we get:
Equation 2: x + y = 5 or x = 5 - y
15x = 10y
15(5 - y) = 10y
75 - 15y = 10y
75 = 25y
y = 75/25
y = 3
Distance 2 = D = 10y
Replacing y with 3, we get:
D = 10y
D = 10(3)
D = 30
So, the distance to island is 30 miles
We know a square is four equal sides. Saying this there are seven squares between A and C so, with the knowns of four equal sides and seven square between A and C you can divide 42/7=6. With this information count six squares to the right from A and the same for C with a result of
B(2,4), and D(2,-3) per graph.
Answer:
x = ±2 /3
Step-by-step explanation:
x²=4/9
Take the square root of each side
sqrt(x²)=±sqrt(4/9)
We know sqrt( a/b) = sqrt(a) / sqrt(b)
x = ±sqrt(4/ sqrt(9)
x = ±2 /3
