Diego says the constant of proportionality is 550 Andrew say is the constant of proportionality is 9 1/6 do you agree with either of them explain your reason
Answer:
The question is incomplete. The complete question is :
A plane traveling at a constant speed flew over Pittsburgh, Saint Louis, Albuquerque, and Phoenix on its way from New York to San Diego.
Complete the table as you answer the questions. Be prepared to explain your reasoning.
segment time distance speed
Pittsburgh to Saint Louis 1 hour 550 miles
Saint Louis to Albuquerque 1 hour 42 minutes
Albuquerque to Phoenix 330 miles
Step-by-step explanation:
We can complete the table as :
segment time distance speed
Pittsburgh to Saint Louis 1 hour 550 miles 550 miles/hour
Saint Louis to Albuquerque 1 hour 42 minutes 93.5 miles 550 miles/hour
Albuquerque to Phoenix 3/5 hour 330 miles 550 miles/hour
Since it is given in the question that the plane is flying in a constant speed from one place top another place.
So, it is maintaining the same speed to cover different distances for different time.
Thus the constant of proportionality is 550.

. A certain tap can fill a tank in 4 hours and
another tap can fill it in 6 hours. If both the taps
are opened, how long will it take for the tank to
be full?
Answer:
Given -
Time taken by first tap = 4 hours.Time taken by second tap = 6 hours.Now, we'll calculate the work done by both the taps -
[tex] \\ \sf \: \frac{1}{4} + \frac{1}{6} \\ \\ \\ \bf \: lcm \: \: of \: \: 4 \: \: \& \: \: 6 = 12 \\ \\ \\ \implies \sf \: \frac{3 + 2}{12} \\ \\ \\ \implies \sf \frac{5}{12} \\ \\ [/tex]
Now, reciprocal it -
[tex] \\ \implies \sf \frac{12}{5} = 2 \frac{2}{5} \\ [/tex]
Therefore, time taken by both the taps will be 2 2/5 hours.
Junior is saving money in his piggy bank. He starts with and adds two pennies each day. Create an table and a graph for the function for which represents the number of days since Junior started saving money and y represents the total money he has saved
The required expression for the Junior started saving money and y represents the total money he has saved is y =2x.
Given that,
Junior is saving money in his piggy bank. He starts with and adds two pennies each day.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Let the number of days, junior saved money be x and the total amount of money he saved be y.
He starts with and adds two pennies each day. which implies,
On day 1 he saved 2 pennies, the next day i.e. day 2 is saved 4 pence and so on and on day x he saved a total of 2x pennies in his piggy bank. Results,
y = 2x
Thus, the required expression for the Junior started saving money and y represents the total money he has saved is y =2x.

Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th floor to the street; but every time he returns, he rides the same self-service elevator only to the 15th floor, where he leaves the elevator and walks up the remaining five flights of stairs. What is happening? Why does he do that?
Answer:
He does that because he is short and his hand can't reach the 20th floor button
Step-by-step explanation:
Mitch does that simply because he is short.
When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.

The table shows the maximum and minimum depths of two submarines. Find the range of depths for each submarine. Then determine which submarine has the greater range of depths.
Submarine A Submarine B
Minimum Depth −146 ft −194 ft
Maximum Depth −532 ft −621 ft
Answer:
Range A = 386ft
Range B = 427ft
B has the larger range.
Explanation:
To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.
Sub A:
-146ft - (-532ft) = 386 ft
Sub B:
-194ft - (-621ft) = 427 ft
Submarine B has a larger range.
A submarine is submerged to a depth
of 650 feet below sea level. It ascends
225 feet and then dives 50 feet.
Write an expression that represents the
new position of the submarine.
Answer:
-650 + 225 = -425 -425 - -50 = 475 feet

1. If an equation contains decimals, what is the first step
you can perform to eliminate the decimals?
Answer:
Multiply by a power of 10
Step-by-step explanation:
By multiplying a power of ten, it will make the decimals whole numbers.
For example: 0.75*10=75
0.0075*10000
To eliminate the decimals, the first step we can perform is to multiply the decimal by a power of 10. If there are n numbers after the decimal point, then we will multiply the decimal by 10ⁿ.
What is decimal?In Algebra, a decimal is a type of number with a whole integer and a fractional part separated by a decimal point. The dot that appears between the entire number and the fractions part is the decimal point. 24.589, for example, is a decimal number. The whole number part is 24 and the fractional part is 589. The decimal point is ".".
How to solve this problem?If an equation contains decimals, then we have to check how many numbers are there in the fractions section. If there are 3 numbers like 24.589, to eliminate decimals we have to multiply 24.589 by 10³ to get a whole number [ Since 24.589×10³ = (24589/1000)× 1000 = 24589].
Therefore, to eliminate the decimals, the first step we can perform is to multiply the decimal by a power of 10. If there are n numbers after the decimal point, then we will multiply the decimal by 10ⁿ.

Victoria is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. It is known that the total charge to use a computer for 5 minutes would be $6 and that the additional rate per minute of use is $0.60. Write an equation for C,C, in terms of t,t, representing the total cost of using a computer for tt minutes at the internet cafe.
Step-by-step explanation:
Given that the initial charge/fee for the first 5 minutes is $6
and also the additional rate per minutes is $0.6
we can model the total charges after the equation of a straight
that y= mx+c
now using the required notation
C= 0.6t+ 6
comparing this with the equation of a straight line
the constant term c is $6 flat rate for the first 5 minutes
the gradient 0.6 is m
the dependent variable x is t
and the cost C is y
Answer:
i believe its c=0.60t+3
Step-by-step explanation:

2 Truths & One Lie
- 39 - b = - 3
1. The Variable is B in this Equation
2. b = -36
3. b = 36
Which one is a Lie?
Justify your decision.
WILL GIVE 20 POINTS!!
Answer:
b = 36 is the lie.
Step by step:
If we plug in b with it equaling -36 the equation will be
-39 - (-36) which you remove the minus from the -36 and change the subtraction to addition and you get
-39 + 36 = -3
In the end b = -3
So the other one must be wrong, but just incase we will plug it in.
-36 - 36 = 0
Plugging in 36 for b results in 0 which is not correct.
