Part A

Deffense [45]

Answer: Not safe

Step-by-step explanation:

Let the angle of elevation of the ramp be θ, then:

$\begin{aligned}&\sin \theta=\frac{1.5}{10}=0.15 \\&\theta=\sin ^{-1}(0.15) \approx 8.63^{\circ}\end{aligned}$

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

A class of 28 students has 7 juniors and 21 seniors. The average (arithmetic mean) score of the juniors on a test was 73. The av

makkiz [27]

Answer:

Step-by-step explanation:

Given that the class has 28 students has 7 juniors and 21 seniors

mean score of the juniors = 73

Therefore, total score of junior = 73 × 7

= 511

mean score of seniors = y

Total score of seniors = 21y

Total score of the class = 511 + 21y

Mean score of the class = 85

Total score of the class = 85 × 28

= 2380

therefore,

511 + 21y = 2380

21y = 2380 -511

21y = 1869

y = 1869/21

y = 89
