Answer:
A security system company's total production costs depend on the number of systems produced according to the following equation: Total Costs = $10,000,000 + $2000 * quantity produced. Given these data, which of the following is a false statement? a. There are economies of scale. b. There are fixed costs associated with this business. c.
Step-by-step explanation:
5a + 15 = 24b so,
10a + 30 = 48b,
sub to third equation,
10a + 30 + 35c = 49
10a + 35c = 19
perform elimination with second equation
10a + 45c = 21
10a + 35c = 19
________________-
10c = 2
c = 1/5
sub to second equation,
10a + (45)(1/5) = 21
10a + 9 = 21
10a = 12
a = 6/5
sub to first equation
(5)(6/5) - 24b = -15
6 + 15 = 24b
21 = 24b
b = 7/8
redo the calculations, correct me if I'm wrong
Answer/Step-by-step explanation:
AC = 1.2
AB = 4
BC = 2.6
DF = 3
DE = 10
EF = 6.5
Thus:
The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.
