The time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the given question,
From 11:15 to 11:30 AM, a whale’s elevation changed from –80 meters to –101 meters.
The whale climbed 21 feet in 15 minutes. The unit rate is 1.4 meters per minute.
There are 14 meters between -80 and -94. The whale will take 10 minutes to reach -94m at a speed of 1.4m/min. The whale began at -80 at 11:15, and 10 minutes later it is 11:25.
Thus, the time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.

pls go do another problem if u dont know how tod this....... Simplify −9+1/4x−6−1/8x show your work
Answer:
-15 + 1/8x
Step-by-step explanation:
calculate the difference
-9 +-6 = -15 then
1/4x -1/8x =1/8x
solution -15+1/8x
How to subtract 1/4x =1/8x ( this should help )
1/4x -1/8 x get the least common denominator which is 2
2x/2x4 -x/8 multiply the numbers
2x/8 - x/8 collect like terms (factor x/8 as 1/8) 1/8x

Please help, I need help on this math question
Answer:
Probably C
Step-by-step explanation:
Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever
For example, 0.2222... or 0.671671.... (The "..." means that it repeats like that forever)
A. 3/7= 0.142857142857142857... (6 repeating digits) This is a repeating decimal because the last six digits continue forever
B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.
C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)
D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.
There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)
But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.
Good Luck! :)

If 3/4 = x/18 , then x is equal to
Answer: x = 13.5
3/4 = x/18
⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Answer:x = 27/2
Step-by-step explanation:
Step 1: Cross-multiply
3/4=x/18
(3)*(18)=x*(4)
54=4x
Step 2: Flip the equation.4x=54
Step 3: Divide both sides by 4x/4=54/4x
= 27/2

4y (4y - 4) - 4 (-4 + 5 + 4y²)
please simplify <3
Answer:
16y - 4
Step-by-step explanation:
4y(4y - 4) - 4(- 4 + 5 + 4y^2)
16y - 16y - 4(1 + 4y^2)
16y - 16y - 4(4y^2 + 1)
16y^2 - 16y^2 + 4
16y - 4
If x-y=6 and x^2+y^2=24, find x^3-y^3.
Answer:
162.06
Step-by-step explanation:
sorry i'm not the best an explaining but i'm confident in my answer.
the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)
then we have this
x-y=6
x+y=4.90
I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)
In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get
2x=10.9 (the y cancels out)
now we have a simple equation and all that is left is to solve it
10.9/2=5.45
x=5.45
Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.
(5.45)-y=6
y= - .55
now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06
Therefore x³-y³≅162.06!

You earn $56 walking your neighbor's dog for 8 hours. Your friend earns $36 painting your neighbor's fence for 4 hours.
What is your pay rate? And What is your friend's pay rate?
Answer:
Your pay rate is:
$ 7 per hour
Your friend's pay rate is :
$ 9 per hour
Explanation:
So if it takes you 8 hours to make $ 56 , you can just divide the total money earned by the time. So it would be 56 ÷ 8 which is 7 .
And if takes your friend 4 hours to make $ 36 , you can divide like we just did . So it would be 36 ÷ 4 which is 9 .
So you make $ 7 per hour and your friend makes $ 9 per hour.
