Compound percentage reduction can be calculated by multiplying the initial number by (1-x)^t where x is the percentage reduction (/100, i.e. 1% reduction is 0.01), and t is the number of times it has reduced.
So:
a)
Where t is the number of weeks.
We can then just substitute in to work out the final pressure:
b) p = 45*0.94^6 =
31psi
The sum of -3 and a number equal to -91 is -88
Answer:
x < - 2
Step-by-step explanation:
given - 4.9x + 1.3 > 11.1 ( subtract 1.3 from both sides )
- 4.9x > 9.8 ( divide both sides by - 4.9 )
Remembering to reverse the direction of the inequality symbol as a result of dividing by a negative quantity.
x < - 2 ← inequality reversed
solution set : x ∈ ( - ∞, - 2 )
Answer:
I thank it is D
Step-by-step explanation:
Answer:
5/√3 inches long.
Step-by-step explanation:
The property is that the lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3. Thus if you know that the side opposite the 60 degree angle measures 5 inches then then this is √3 times as long as the side opposite the 30 degree so the side opposite the 30 degree angle is 5/√3 inches long.
