Answer: C = 0,3x + 380
Step-by-step explanation: Assuming that a linear relationship is suitable model, C is a function of d, we can say that:
C = d.x + k. where x is what we call a variable cost and k is a fixed cost. We have to assume a fixed cost. If it does not exist, the value will be zero.
This way: for may we have 494 = 380x+k and for June we have 638 = 860x+k.
Let's subtract them
638 = 860x+k
494 = 380x+k (-)
______________________
638 = 860x+k
-494 = -380x-k
_____________________
144 = 480x
x=144/480
x=0,3
For k, we substitute in one of the equations
638 = 860.0,3 + k
638 = 258 + k
k = 380
∴ C = 0,3x+380
100,000 is basically the same thing as 100k
Answer:
10 units
Step-by-step explanation:
Given that:
Cos a = 3 /5
From trigonometry ;
Cos θ = Adjacent / hypotenus
Side Adjacent angle a = 3 = FD
Hypotenus = 5 = DE
3 / 5 = FD / DE
FD = 6 units
3/5 = 6/DE
DE * 3/5 = 6
DE = 6 ÷ 3/5
DE = 6 * 5 /3
DE = 30 /3
DE = 10 units
Answer:
12
Step-by-step explanation:
If the perimeter is 58,
take 17(2) for booth sides.
Which you will get 34.
58-34=24
Now you know that the remainder is the two vertical sides.
24/2=12
BC=12
