26.98. You have the following information given in the problem above:
- Lou filled the tank with gas that cost $3.80 per gallon.
- Lou's car had 5.9 gallons in the 13-gallon tank.
2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
The correct answer would be C :^)
Depending on how large the figure actually is, if it is specifying that on that specific paper what to use to measure it, use a ruler also for part b a possible dimension could be 4 cm x 8cm
Answer:
n must be 3
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2L + 2W. Substituting (1/2)(n - 6) for L and 2n + 5 for W, we get:
P = 60 = n - 6 + 4n + 10, or:
60 = 5n + 4, or:
15 = 5n
Then n must be 3.
Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
