Answer: Correct Answer is 4th option , 28
Step-by-step explanation:
We can find the measure of the angle using the tangent.
We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.
So, Tan of angle T = RG / RT
or, Tan of angle T = 8/15
or, angle T = tan inverese of 8/15
or, angle T = 28.07
So, angle T rounded to nearest degree = 28
Hope this helps.
Thank you.
The equation is derived from the conservation of energy, specifically from potential energy stored at a given height in a gravitational field.
When potential energy is completely converted to kinetic energy you have:
(mv^2)/2=mgh divide both sides by the mass m
v^2/2=gh multiply both sides by 2
v^2=2gh take the square root of both sides
v=√(2gh) and working with imperial units for acceleration due to gravity, g=-32ft/s^2
v=√(-64h) but the change of h as it falls is negative h so
v=-√(64h) so if an object falls from a height of 88ft we have:
v=-√(64*84)
v=-√5376
v≈-73.32 ft/sec (to the nearest hundredth of a foot per second)
Note that this is the velocity, it is negative 73.32 ft/sec.
The question inadvertently asked for velocity and provided answers for SPEED. Velocity is a vector and has both magnitude and direction, whereas speed just has magnitude.
So its final speed is 73.32 ft/sec
So if they actually wanted velocity none of their answers is correct :P
Answer:
The sandals cost before tax $25.
Step-by-step explanation:
Let us assume that the sandals cost before tax $x.
So, after giving an 8% tax the price will be 
.
If the $15 gift certificate on that after tax price and the final cost of the sandals becomes $12, then
1.08x - 15 = 12
⇒ 1.08x = 27
⇒ x = $25
Hence, the sandals cost before tax $25. (Answer)
