$1000 - ($20 + $20) = $60
$60 / $10 = 6 paper weights
Answer:
128 ft / second.
Step-by-step explanation:
It's acceleration is due to gravity and is 32 ft s^-2.
To find the velocity when it hits the ground we use the equation of motion
v^2 = u^2 + 2gs where u = initial velocity, g = acceleration , s = distance.
v^2 = 0^2 + 2 * 32 * 256
v^2 = 16384
v = 128 ft s^-1.
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = 
, then
cos45° = 
= 
= ( cross- multiply )
c = 3
Answer: x - 30 = 10
Step-by-step explanation:
x - 30 = 10
x = 30 + 10
x= 40
The answer is 7.
Hope this helps.
