Answer:
x=4
Step-by-step explanation:
3^(x-1)=27
=>3^(x-1)=3³
=>(x-1)=3
=>x=4
subtracting all i think should equal 0.29
Answer:
12
Step-by-step explanation:
Answer: E(p) = 6/7√37/q
Step-by-step explanation: if q = 37/p^0.85, then we are to make p the subject formula.
Now multiply both sides by p^0.85, we will have
P^0.85q = 37
Divide through by q, we get
P^0.85 =37/q
But 0.85 = 6/7
So we take the 6/7 root of both sides, we get
P = 6/7√37/q
Therefore E(p) = 6/7√37/q
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
