A represents 77 units
You take the only number given (75) and count the tick marks, adding one every time you go right, subtracting one every time you go left. Mark A is 2 tick marks to the right of 75, so you add 2 to 75, making 77 units

= 64^(t^3)*64^(-t/2)
= 64^(t^3)*(64^(-1/2))^t . . . . change the sum of exponents to a product
= 64^(t^3)*(1/√64)^t . . . . . . negative exponent signifies inverse, 1/2 power is sqrt
= 64^(t^3)/8^t . . . . . . . . . . . simplify
= (4^3)^(t^3)/8^t . . . . . . . . . .replace 64 with 4^3
= 4^(3t^3)/8^t . . . . matches the first selection only

Andy watches 10 television shows every week. He watches dramas, comedies, and reality shows. Dramas are 1 hour long, comedies ar
Lunna [17]

Answer:

d+0.5c+2r=8\\\\ c=2d

Step-by-step explanation:

Let d= dramas

c= comedies

r= reality shows

Dramas are 1 hour long, comedies are 30  minutes, and reality shows are 2 hours long.

Total time spent on watching = 1 \times(d) + 0.5 \times (c) +2  \times(r)= d+0.5c+2r

 [  30\ minutes=\dfrac{30}{60} \ hours = 0.5 hour \ \ (1 hour = 60\ minutes)  ]

Since he spent 8 hours for this, that means

d+0.5c+2r=8     → First equation

He watches twice as many comedies as dramas.

i.e. c=2d → second equation

So, the system of equations could be used to determine how many of each type of show he watches each week:

d+0.5c+2r=8\\\\ c=2d
