an airplane flies 3300 miles with the wind in 3 hrs 18 minutes. it takes 4 hrs 24 mins to make the return flight against the same wind. find speed of airplane and wind.
Answer:
The speed of aeroplane =875 miles/hr and the speed of wind =125 miles/hr.
Step-by-step explanation:
Let’s assume the speed of the plane =x miles/hr
And let the speed of wind =y miles/hr
So, the speed of the aeroplane in the direction of wind =(x+y) miles/hr
Speed of the aeroplane in the opposite direction of wind =(x–y) miles/hr
We know that, distance=speed×time
Then according to the given conditions, we have
3300=(x+y)×(3+(18/60))
here convert 18mins to hour by dividing by 60 and add to 3hrs.
⇒x+y= 3300/3.3
⇒x+y=1000 … (i)
And,
3300=(x-y)×(4+(24/60))
here convert 24mins to hour by dividing by 60 and add to 4hrs.
⇒x-y= 3300/4.4
⇒x-y=750 … (ii)
Adding equation (i) and (ii), we get
2x=1750
⇒x= 1750/2
=875
Substituting the value of x in equation (ii), we get
875−y=750
⇒y=875-750
⇒y=125
Therefore, the speed of aeroplane =875 miles/hr and the speed of wind =125 miles/hr.

Function g can be thought of as a translated (shifted) version of f(x)=x^2
Answer:
g(x)=x^2 -6x +5
Step-by-step explanation:
Answer:
g(x) = (x - 3)² - 4
Step-by-step explanation:
When values are directly added to the "x" variable (usually inside of parentheses), the function shifts to the left that many units.
When values are directly subtracted from the "x" variable, the function shifts to the right that many units.
When values are added to an overall function, the function shifts upwards that many units.
When a value is subtracted from an overall function, the function shifts downwards that many units.
We can determine how the function has been translated by looking at the changed position of the vertex (the lowest point of the line).
As you can see, the new vertex now lies on x = 3 rather than x = 0.This means that there should be a -3 directly next to the "x" variable in the new function.
The new vertex also now lies on y = -4 rather than y = 0. Therefore, there should be a -4 added to the overall equation.
These changes make the new function:
g(x) = (x - 3)² - 4

Soil sells for 8 1/4 cents per pound. How much would you save if you bought a 100- pound sack for $7.45?
Answer:
$0.80
Step-by-step explanation:
If the 100 pounds was bought separately (of course in real life you will probably not)
= 100 pounds x $0.0825/pound
= $8.25
As you can see it will cost more than if you buy a 100 pound sack.
Cost Difference = $8.25 - $7.45 = $0.80
That means you will save $0.80 from it.
There will be a profit of $0.8 if the soil is bought for $7.45 for 100- pound sack and sold for 8 1/4 cents per pound.
What is Multiplication?Multiplication in mathematics is the process of adding a number repeatedly up to the times of another number. If two numbers, namely a and b are multiplied, this is denoted by a × b. This means that 'a' is added repeatedly to itself up to b times or b is added repeatedly up to 'a' times.
Amount got for 1 pound soil after selling = 8 [tex]\frac{1}{4}[/tex] cents
= 33/4 cents
= 8.25 cents
= 8.25 / 100 dollars
= 0.0825 dollars
For 100 - pound sack, amount got after selling = 0.0825 × 100
= 8.25 dollars
Cost for 100 - pound sack = $7.45
Profit = $8.25 - $7.45
= $0.8
$0.8 will be saved if you bought a 100- pound sack for $7.45.
