Answer:
37.68in
Step-by-step explanation:
circumference = 2πr
r= radius = diameter/2 = 12/2 =6 in
C= 2πr = 2 x 3.14 x 6= 37.68in
Answer:
See below.
Step-by-step explanation:
In all triangles, the three interior angles will add up to 180°. Therefore:
Remember that the little square means a right angle.
Now, solve for <em>x</em>.
Now, plug <em>x </em>back into the equations to find each angle:
1)
2)
3)
Answer:
and 4
Step-by-step explanation:
To simplify like surds, add/ subtract the coefficients.
(a)
(6 - 5)
= (1)
=
(b)
( 1 + 3)
= (4)
= 4
Answer:
option (a) $250
Step-by-step explanation:
Data provided in the question:
Fixed cost = $500
For 100 units produced Total cost = $3,500
For 101 units produced, Total cost = $3,750
Now,
Marginal cost is calculated as:
Marginal cost =
thus,
Marginal cost =
or
Marginal cost =
or
Marginal cost = $250
Hence,
The correct answer is option (a) $250
