Answers
Answer:
Step-by-step explanation:
You only need two equations for this problem. First determine variables:
h represents height
R represents rate of rise
t represents time needed to reach the full height
Note that R will be expressed as a measure of distance over minutes, for instance meters per minute, and h will be expressed in units of distance, such as meters. t is expressed in minutes.
The equations needed are as follows:
(3/2)min * R= (6/20) h
{One and a half minutes times rate of rise equals six twentieths of full height. When you multiply minutes by rate of rise, the minutes divide out leaving a distance unit}
t = h/R
{Time to reach full height equals full height divided by rate of rise. When you divide the height, expressed in distance, by the rate, expressed in distance over time, the distance units divide out leaving a time unit}
It is not necessary to know either R or h since they will divide out when you solve for t.
First, solve for h in the first equation.
Then, take the answer from that and substitute it for h in the second equation.
This will produce an equation that will reduce to a known t value.

The key clue is "at a constant rate." That means that rate = (distance)/(time) is always the same, so we can set them equal.
rate given = total rate
(1 1/2 minutes) / (6/20 d) = (t minutes) / (1 d) [t=time; d=total height of drawbridge]
t = ( (1 1/2 minutes) / (6/20 d) ) (1 d) [multiply both sides by 1 d; reverse equals]
t = (1 1/2) / (6/20) minutes [d cancels out, leaving only minutes]
t = (3/2) ( 20/6) minutes [convert to improper fraction; to divide by fraction, invert and multiply]
t = 5 minutes

Sales tax value = 12.80 divided by the the total cost ( $320) multipled by hundred
So 12.80/320 x 100 = 4
So 4%

Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
GRAPH IN SCREENSHOT
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.
Answers
26375
On the graph, it tells you how much fuel is left after 2 hours of the journey.
If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.
Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.

Step-by-step explanation:
Your main goal is to get Y by itself on one side.
To start subtract 2x from both sides. This will give you -3y=42-2x.
Then you divide both sides by -3 to get Y by itself.
That will leave you with ...

Diego was asked to plot these points: (−50,0) ( − 50 , 0 ) , (150,100) ( 150 , 100 ) , (200,−100) ( 200 , − 100 ) , (350,50) ( 350 , 50 ) , (−250,0) ( − 250 , 0 ) . What interval could he use for each axis?
Answers
Answer:
We have the points:
(-50, 0)
(150, 100)
(200, -100)
(350, 50)
(-250, 0)
First, we need to find the smallest and largest values of the x-component.
The smallest value is x = -250
The largest value is x = 350
Then the interval that we choose for the x-axis should include these two values (so we can plot the points)
Then we need to use, at least, the interval [-250, 350] (A interval that is a little bit larger than that will be easier to read, but that is the minimum he needs to do the plot)
Now let's do the same with the values of the y-components.
The smallest value is y = - 100
The largest value is y = 100
Then the vertical interval should be [-100, 100] or a little bit larger, like in the horizontal case.
We also can see that the values of x and y seem to jump in multiples of 50, then each unit of the grid could represent 50 units, so it is easier to plot. (These are also called intervals, and also theses will depend on each individual axis, but in this case we could use the same for both of them, because it works well for both axis)
Use an interval of 50, because all the
coordinates involve points that are greater than 50 and multiples of 50.

Find the 16th term of the arithmetic sequence whose common difference is d=6 and whose first term is a 1=3
Answers
Answer:
93
Step-by-step explanation:
This question is on Arithmetic sequence, and we can find the 16th term using the Arithmetic sequence formula below;
aₙ= a₁ + (n-1)d
Where n= nth term in that particular sequence.
n₁= first term in the particular sequence.
d= common sequence between the terms.
Given:
d=6
a₁ =3.
Using the formula above,
a₁₆= 3 + (16-1)6
= 3+(15)6
=3+90
=93
Hence, the the 16th term of the arithmetic sequence is 93
