Answer: Not safe
Step-by-step explanation:
Let the angle of elevation of the ramp be θ, then:
But the maximum angle for the ramp cannot exceed 7.1°. The calculated angle of elevation will make it difficult, if not impossible, for motorized wheelchairs to get up the ramp.
Therefore, the ramp at the local library is not safe for motorized wheelchairs

Answer:
2160 inches
Step-by-step explanation:
The actual length of a soccer field is 300 feet. If the width of the field is 180 feet, then what should the width of the scale drawing be in inches?
1 foot = 12 inches
Width of the field = 180 feet
Hence:
1 foot = 12 inches
180 feet = x
x = 180 × 12 inches
x = 2160 inches
Width of the scale drawing in inches = 2160 inches
16<2(3x-1)<28 divide all terms by 2
8<3x-1<14 add 1 to all terms
9<3x<15 divide all terms by 3
3<x<5
x=(3,5) in interval notation
On a number line, it would be a line segment from 3 to 5 with open circles at 3 and 5.
On a coordinate system graph, it would be an infinitely high shaded plane between the vertical lines x=3 and x=5
