Answer:
4 hours
Step-by-step explanation:
first you find out how much 3/4 of a mile is in 9 miles
1/4 = .75
9 divided by .75 = 12
So it takes 12 of 3/4 of a mile to go to 9 miles
Then multiply 12 by 1/3 to find he time since it takes 1/3 of an hour to travel 3/4
12 * 1/3 = 4
So it will take Mt Gregg 4 hours to travel 9 miles
Answer:
Step-by-step explanation:
Given complex number is:
To find:
Answer in rectangular form after using De Moivre's theorem = ?
i.e. the form (not in forms of angles)
Solution:
De Moivre's theorem provides us a way of solving the powers of complex numbers written in polar form.
As per De Moivre's theorem:
So, the given complex number can be written as:
Now, using De Moivre's theorem:
So, the answer in rectangular form is:
Answer:
42
Step-by-step explanation:
I'm pretty sure that this is the answer.
The area would be 441 m².
We first find the length of the given rectangle. We know area is length times width, that the area is 405 and the width is 15; this gives us:
405 = 15L
Divide both sides by 15:
405/15 = 15L/15
27 = L
Calculate the perimeter of the rectangle:
P = 2L + 2w = 2(27) + 2(15) = 84 m
The side of the square is 1/4 the perimeter of the rectangle we just found:
1/4(84) = 21 m
The area of a square is equal to its side length squared:
A = s² = 21² = 441 m²
D. Start Fraction 19 over 35 End Fraction
the denominators need to be equal to add so 1/7 converts to 5/35 and 2/5 converts to 14/35
so 5/35 + 14/35 = 19/35
