Answer:
Total money: $58
percentage of total amount spent on lunches: 30%
30/100 = 0.3
To find money spent each week on lunch, multiply by percentages:
58*.30= 17.4
Total money spent on lunch is $17.40
Explanation:
<u>Answer:</u>
Ptolemy accounted for 'retrograde motion' in his model of the solar system by introducing smaller circles named 'epicycles'.
<u>Explanation:</u>
- According to Ptolemy, the Sun and the other planets in the Solar system orbited around the Earth.
- The Greeks were convinced that Ptolemy's earlier model did not provide for backward or the retrograde motion.
- Ptolemy thought over it for a while and theorized the possibility of 'epicycles'.
- According to Ptolemy, the planets that orbited Earth also orbited another smaller point.
- The smaller orbits followed by the planets while in motion around the Earth in a larger orbit were introduced by Ptolemy as 'epicycles'.
- Until Kepler proposed his models of the functioning of the Solar system, Ptolemy's models were considered the most relevant.
Answer:
The volcano over a mantle hotspot
Explanation:
I say this because lava comes from the grinding of those mantles, which melt rocks and make lava. If the mantles are super active, the lava will more than likely be explosive. Think of this (heat wise) as tea boiling in a kettle. The stove is the mantle, kettle as volcano and water as lava. When the mantles get hot enough they push that heat and pressure into the water, making it boil and when the steam starts to squeal out of the kettle, the volcano has erupted. Hope this helped!
