Answer: {y | y > 0}
Answer:
$75.6
Explanation:
If the original cost was $70 and it was marked up 20%, the price after this is calculated as:
$70 + $70(0.2) = $70 + $14 = $84
Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.
Then, it was discounted 10%, we get that the selling price is
$84 - $84(0.1) = $84 - $8.4 = $75.6
Where $84(0.1) = $8.4 is the discount made on the initial price.
Therefore, the answer is $75.6
Answer:
80
Step-by-step explanation:
0.35x = 28 (divide each side by 0.35)
x=80
Answer:
6 min
Step-by-step explanation:
(a) Calculate the change in height
Δh = h₂ - h₁ = 30 000 ft - 6000 ft = 24 000 ft
(b) Calculate the time to reach altitude
distance = rate × time
Divide both sides by rate
time = distance/rate = 24 000 ft × (1 min/4000 ft) = 6 min
It takes 6 min to reach cruising altitude.
