Answer:
The amount Roberta makes an hour is $119.5
Explanation:
Let the number Roberta makes be x hours.
Amount earned in x hours shift - 9*x + 12.5% of the amount of jewelry sold.
Number of hours worked by Roberta if 9 hours and jewelry worth $380 is sold by her.
Substituting the values:
Amount earned in an 8 hour shift = 9*8 + 12.5% od 380
= 72 + 0.125 * 380 (12.5% = 0.125)
= 12 + 47.5
= 119.5
Hi there! This question is a bit confusing.
Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge.
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
Your answer would be "Secondary cells are rechargable"
Have a great rest of your day!
Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
