A lost turtle - swimming 13 feet below the surface of the water - begins to ascend at 0.5 foot per second. In hopes of (harmlessly) capturing the turtle, a diver jumps into the water to a depth of 4 feet before descending at a rate of 0.25 foot per second.a) Write an equation to model the position of the turtle at any given time.



b) Write an equation to model the position of the diver at any given time.



c) After how long will the diver be able to catch the turtle?



d) At what depth will the diver be able to catch the turtle?

What % of 25 is 21?
​

Answers

Answer: 84%

Step-by-step explanation:

1. Since 25 is the output value, we can assume that it is 100%

2. Now we out what we want to find with x

3. From step one, 25=100%

4. In the same line, x%=21

5. This gives us 2 equations:

100%=25(1)

x%=21(2)

6. By dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit (%); we have (set up a proportion)

7. Then, take the reciprocal and solve. You should end up with x=84%

Answer:

0.84

ur answer would be A.... hope i helped

A. 1/2

20 bags total, 10 bags of pretzels. 10/20(common denominator is 5) simplified = 2/4= 1/2

So the equation you’ll use for both is
WP = mg • h
It’s delta height generally.

1.) .9 m = h

2.) 216 = WP

Find the x and y intercepts of 10x = -5y

Answers

Answer:

(0,0)


Step-by-step explanation:

To find the x intercept we set y = 0 and solve for x

10x = -5y

10x = 0

x =0

To find the y intercept we set x = 0 and solve for y

10x = -5y

0 = -5y

0=y

The x and y intercepts are 0

Answers

You simply analyze the bar graph.
At the weight 1 to 2 pounds, there are 2 cantaloupes.
At the weight 3 to 4 pounds, there are 5 cantaloupes.
At the weight 5 to 6 pounds, there are 8 cantaloupes.
At the weight 7 to 8 pounds, there are 9 cantaloupes.
Adding the total cantaloupes yields
2 + 5 + 8 + 9 = 24 cantaloupes

Is 2115 divisible by 9 if so explain why or why not

Answers

Yes It is because when you divide any number by another and it does not have a decimal it is divisible by that number and when you divide 2115 by 9 it comes out 235 (without a decimal) so it is divisible.
Hope that makes sense lol
Hope I helped :)
yes because if you divide 2115 by 9 you get 235
