<span>Product means multiplication, so I would multiply 379 and 8.
379 x 8 = 3032
3032 is directly in between 3031 and 3033

Answer:
(A) 5.47 km
(B) 1.38 km
Step-by-step explanation:
The relationship between Pressure (mmHg) and Height (km) is given by the equation below:
p =760 e⁻ 0.145h----------------------------------------------------- (1)
(a) The height of the aircraft can be calculated by making 'h' the subject of equation (1)
In (p/760) = -0.145 h
h = -In (p/760) /0.145
h= In (760/p)/ 0.145------------------------------------------------- (2)
For the aircraft, p =344 mmHg; substituting into (2)
h = In (760/344)/0.145
= 0.7926/0.145
= 5.4662 km
≈ 5.47 km
(b) p= 622 mmHg at the mountain top. Substituting into equation (2) we have:
h = In (760/622)/0.145
= 0.2003 / 0.145
= 1.3813 km
≈ 1.38 km
Answer:

Step-by-step explanation:
$16 + 4% = $16.64
Answer:
20.5
Step-by-step explanation:
Let's label the vertices ABC as in the diagram below. Then
Data:
α = 34 °
β = 90 °
c = 17
Calculation:
cosα = AB/AC
Multiply each side by AC
ACcosα = AB
Divide each side by cosα
AC = AB/cosα = 17/cos34 ≈ 17/0.8290 ≈ 20.5
