Answer: The correct answer choice is B
Step-by-step explanation:
I graphed each function on the desmos calculator and answer choice B matched the graph.
Answer:(1) The correct option is b. (2) The correct option is c.
Explanation:
(1)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.

It is given that the angle DAB is 63 degree.

Therefore, the correct option is b.
(2)
It is given that the △ABD≅△FEC.
So by (CPCTC) corresponding parts of congruent triangles are congruent.




Therefore, the correct option is c.
Given:
Henry: 130 flyers in 95 minutes.
Nick hangs flyers 50% faster than Henry
Adam hangs flyers 20% slower than Henry
Remaining flyers: 870
Henry's rate per minute = 130/95 = 1.37 flyers per minute
Nick: 1.37 * 1.50 = 2.055 or 2.06 flyers per minute
Adam: 1.37 * 0.80 = 1.095 or 1.10 flyers per minute
1.37 flyers + 2.06 flyers + 1.10 flyers = 4.53 flyers per minute.
870 flyers ÷ 4.53 flyers per minute = 192 minutes
the constant proportionality for the flyer hanging of all three is 4.53 flyers per minute. They will finish hanging the remaining 870 flyer within 192 minutes.
Answer:
517190400 times
Step-by-step explanation:
83x60=4920 (per hour)
4920x24=118080 (per day)
118080x365=43099200 (per year)
43099200x12=517190400 (in 12 years)
