What equation models the data in the table if d = number of days and c = cost?
Days
2
3
5
6
Cost
16
24
40
48
A. d = 8c
B. c = d + 8d
C. c = 8d
D. c = d + 8
Answers
Answer: C. c = 8d
I'm gonna go with c = 8d
Step-by-step explanation: c = 8d
D) c = 8d
The cost is a direct variation of the days by a factor of 8.
...................................................................................................................................................
Answer:
Correct option is:
c=8d
Step-by-step explanation:
Days Cost
2 16=2×8
3 24=3×8
5 40=5×8
6 48=6×8
As we can clearly observe from the table above that if d is the number of days then the cost c is written as:
c=8d
Hence, Correct option is:
c=8d
What is the measure of the smallest angle?
63°
57°
53°
64°
Answers
Answer: 53°
Step-by-step explanation:
3x - 4 + 3x + 6 + 4x - 12 = 180
10x - 10 = 180
Add 10 to both sides
10x = 190
Divide both sides by 10
x = 19
3x - 4
3 (19) - 4 = 57 - 4
= 53
3x + 6
3 (19) + 6 = 57 + 6
= 63
4x - 12
4 (19) - 12 = 76 - 12
= 64
The smallest angle is 53°
