Original price was $234.95
49% marked down = $234.95 *49 / 100 = $115.13
So now the sale price = original price - price of 49% marked down
sale price = $234.95 - $115.13 = $119.82
Answer: sale price of a DVD player having a red tag marked down by 49% should be $119.82
Don't you just grab the volume of the box and subtract the volume of the basketballs.
A. No matter what M is, it will correspond to the squared version of 18m
We are tasked to solved for the length of the ramp having an inclination of 15 degrees with the ground and 10 feet from the end of the ramp to the base of the building of the ground. Using trigonometric properties, we have a formula given an angle and the its opposite sides which is,
sin(Angle)=opposite/hypothenuse
hypothenuse would be the distance or the length of the ramp.
so we have,
sin(15)=10/hypothenuse
Cross-multiply, we have,
hypothenuse=10/sin(15)
using scientific calculator having a DEG mode,
hypothenuse=38.63703
Rounding of in nearest tenth we get,
hypothenuse=38.6 ft
Therefore, the ramp is 38.6 ft long
