1 answer:
loris [4]3 years ago
7 0

Step-by-step explanation:

If we graph elevation vs time, the rate of change is the slope of the line.

At t = 0, h = -90.

At t = 15, h = -20.

m = (-20 − (-90)) / (15 − 0)

m = 70/15

m = 4.67

The closest answer is B.  The elevator traveled upward at a rate of 4 feet per second.

if the humpback whales had traveled at the same rate for 32 days,how many more miles would the have traveled than the grey whale
Nataliya [291]

Answer:

192 miles more than the gray whales.

Step-by-step explanation:

first, get the rate of each whale per day. To put it in simpler terms, divide 2,240 miles by 28 to find how much the humpback whales travel in a day. next, do the same for the gray whales. I got that the humpback whales traveled 80 miles in a day and the gray whales traveled 74 in a day. Multiply 80 miles by 32 days to get the distance the humpback whales travel in 32 days (2,560 miles). Since you know the distance the Gray whales traveled in 32 days, you do not need to solve for it. Subtract 2,560-2,368 and you get 192 miles.


Hope this helped. If you can, label this answer as brainliest. Dont hesistate to ask if you have any questions. <3

Tony finishes baking cookies at 10:33 am he started at 7:18 am now long was he baking cookies?
Ber [7]
To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:

  10:33
-
  7:18

Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies.

Which is the graph of an odd monomial function?
malfutka [58]
In order for a function to be odd, we know that f(-x) = -f(x)
Hence, the only graphs that are odd are the cubics.

Now, a monomial is defined as an equation with only one term in it. Since the first two is shifted, they must consist of at least 2 terms.

Hence, the only viable answer is the third graph.

What is the sum of -64/5 and 64/5 ?
77julia77 [94]

Answer and Explanation

<h2>0</h2>

<em>This is because they are both the same opposite number, and you are adding.</em>

But, if it was, \frac{64}{5}+\frac{64}{5} then it would be 25.6 or \frac{128}{5}.

<em>So, the answer is 0.</em>

<em>Hope this helps =)</em>
