So, We Need To Write An Equation. Lets Make Some Variables.
Max Amount He Can Spend: X
Max Amount Of Hours: H
Cost Per hour: P
Deposit : D
So, Lets Start.
We Can Write:
H = (X - D) / P
Now, Just Plug In The Known Values.
H = (30 - 15) / 3
That Is Our Equation.
Now, Just For Fun, I Will Solve It.
So, We Need To Simplify.
30 - 15 = 15.
So, We Have:
H = 15/3
So, We Know:
15/3 = 5.
So, We Can Substitute 5 for 15/3.
We Get:
H = 5
So, He Can Canoe For 5 Hours.
Answer:
δL/δt = 634,38 ft/s
Step-by-step explanation:
A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write
L ( distance between aircraft and person )
L² = x² + y² or L² = x² + (405)²
Taken partial derivatives with respect to t we get:
2*L*δL/δt = 2*x*δx/t + 0
Then L*δL/δt = x*δx/dt
At the moment of the aircraft passing over the tower
x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²
So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft
Then:
δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s
δL/δt = 634,38 ft/s
Answer:
11/2
Step-by-step explanation:
5y+3=36-y
1) Subtract 3 from both sides:
5y=33-y
2) Add y to both sides:
6y=33
3) divide both sides by 6:
y=33/6
4) Simplify the fraction:
11/2
Answer:
Step-by-step explanation:
We know that PEMDAS is a shortened acronym for the order in which we do operations in an expression, which is as following in the correct order:
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
Now your question asks you to solve the expression using PEMDAS, however that is what we would do regardless as <em>in algebra </em>PEMDAS is always in effect.
Lets break it down! 
Simple enough! We just do the respective operations inside the parenthesis first (as per pemdas), which after completion yields us
Since x is undefined and the expression is completely simplified, there is nothing more we can do.
Answer:
2(w - 6)
Step-by-step explanation:
subtract 6 from w and then multiply by 2
