Answer:
it has to be negative because it's below sea level so it's -20
Answer:
BC = 2.24 cm
AC = 1.99 cm
Step-by-step explanation:
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin θ = o/h
cos θ= a/h
tan θ = o/a
θ = 40°
h = 3cm
a = AC
o = BC
first let's calculate BC
sin θ = o/h
o = sin θ * h
o = sin 40 * 3
o = 0.7451 * 3
o = 2.24 cm
BC = 2.24 cm
having one leg and the hypotenuse we can calculate the other leg with pitagoras
h^2 = c1^2 + c2^2
3^2 = 2.24^2 + AC^2
9 = 5.02 + AC^2
AC^2 = 9 - 5.02
AC = √ 3.98
AC = 1.99
Answer:
-5/32
Step-by-step explanation:
Answer:
7A
Step-by-step explanation:
On first week
Quantity of tomato = 25 tons
profit per ton = $250
So if she sells tomato on first week then total profit = 25 * 250 = $6250
On second week
Quantity of tomato =27 ton
profit per kg =$ 235
So if she sells tomato on second week then total profit =27* 235= $6345
On third week
Quantity of tomato = 29 ton
Profit per kg = $220
So if she sells tomato on third week then total profit = 29*220 = $6380
Now consider fourth week
Quantity of tomato =31 ton
Price per kg = $205
So if she sells tomato on fourth week then total profit =31*205 = $6355
so she must ship her tomatoes on third week i.e she will attain $ 6380 as profit.
