Answer:
The seagull's position halfway is 85.5 feet.
Step-by-step explanation:
The seagull is at 125 1/2 feet above the sea level.
The fish is at 45 1/2 feet below the sea level.
The distance between the seagull and fish = seagull's distance above the sea level + fish's distance below the sea level
= 125 1/2 + 45 1/2
= 
+ 
= 
= 171
The distance between the seagull and fish is 171 feet.
Since the seagull stops halfway, then;
seagull's position = 
= 85.5
The seagull's position halfway is 85.5 feet.
Answer: the slope is 2/8
Step-by-step explanation:
(6 - 4)/(6 - (-2)) = 2/8
Answer:
The probability of drawing exactly one blue marble is 15 over 32
Step-by-step explanation:
did test
Step-by-step explanation:
you know the area of a rectangle is length × width.
we know length = 10 m.
and we know the area = 60 m².
60 = 10×width
width = 60/10 = 6 m.
the fence is the perimeter, which is for a rectangle
2×length + 2×width
which is logical, as when you fully go around a rectangle, you have to pass the length 2 times and the width 2 times, right ?
length of fence = 2×10 + 2×6 = 20 + 12 = 32 m.
Answer:
Step-by-step explanation:
The zeros of the function can be found by factoring. Since this has already been started with completing the square, we will just pick up from where it was left and finish factoring. Set the quadratic equal to 0 first.
then move over the 9:
"undo" the squaring by square rooting both sides to get
x - 8 = ±3. And then add over the 8 to get the solutions
x = 8 + 3 and x = 8 - 3. The solutions, then, are
x = 5 and x = 11
