Answer:
312 cm³
Step-by-step explanation:
volume of triangular prism = area of triangle x length
area of triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 8 x 6 = 24 cm²
Therefore, volume of the prism = 24 x 13 = 312 cm³
$5.50. if he washes his dog every week, he is getting $6.60 automatically. So if we do simple math, 12.10-6.60= 5.50
Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
Answer:
735N
Step-by-step explanation:
According to Newton's second law;
Force = mass * acceleration due to gravity
'
Given
Mass = 75kg
Acceleration = 9.8m/s^2
Substitute into the formula;
F = 75 * 9.8
F = 735N
Hence the force required is 735N
Answer:
The angle is 28.
Step-by-step explanation:
If we consider the system below (were "A"is the angle):
A + [(x/2)-14] = 90 (complement)
A + x = 180 (suplement)
We can isolate "X=180 - A" and apply this in the first equation. This way we are able to have only one variable, and w'll see that A=28.
