Answer:
CDE = 10
Step-by-step explanation:
in parallelogram, adjacent angle are supplementary.
A+ B = 180
100 + B = 180
B = 180 - 100
B = 18
E ≅ B
E = 80
EC⊥ DC
DCE = 90
in ΔDCE,
DCE + CED + CDE= 180 {Angle sum property of triangle}
90 + 80 + CDE = 180
170 + CDE = 180
CDE = 180 - 170
CDE = 10

Answer:

Step-by-step explanation:
⇒ 3x² + 5
Substitute x = 4 :
⇒ 3(4)² + 5
⇒ 3(16) + 5
⇒ 48 + 5
⇒ 53
Answer:
<u>The correct answer is D. Any amount of time over an hour and a half would cost $10.</u>
Step-by-step explanation:
f (t), when t is a value between 0 and 30
The cost is US$ 0 for the first 30 minutes
f (t), when t is a value between 30 and 90
The cost is US$ 5 if the connection takes between 30 and 90 minutes
f (t), when t is a value greater than 90
The cost is US$ 10 if the connection takes more than 90 minutes
According to these costs, statements A, B and C are incorrect. The connection doesn't cost US$ 5 per hour like statement A affirms, the cost of the connection isn't US$ 5 per minute after the first 30 minutes free as statement B affirms and neither it costs US$ 10 for every 90 minutes of connection, as statement C affirms. <u>The only one that is correct is D, because any amount of time greater than 90 minutes actually costs US$ 10.</u>
Answer:
- <em>The correct option is D</em>
Step-by-step explanation:
From the figure, we observe that,



Since the corresponding line segments are equal in length.
Therefore, the scale factor is 1.
Hence, the correct option is D.
