Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required = ![\frac{distance}{speed}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%7D%7Bspeed%7D)
time required = ![\frac{29728.9728}{1400}](https://tex.z-dn.net/?f=%5Cfrac%7B29728.9728%7D%7B1400%7D)
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
The overall efficiency of this plant will be 83%. The plant's efficiency is calculated by dividing work output to that of heat supplied.
<h3>What is efficiency of the plant?</h3>
The efficiency of the plant is found as the ratio of work output to the heat supplied.
The heat supplied is found as;
Q= m h
Q=30,000 kJ/kg,× 60 tons/h
Q=30,000 ×10³×60×10³/3600
Q=3×10⁷×16.66
Q=180.720×10⁶
Q=180 mw
The overall efficiency of this plant is ;
![\eta = \frac{W}{Q_{supplied}} \\\\ \eta = \frac{150}{{180}} \\\\ \eta=0.833 \\\\ \eta= 83 \%](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%5Cfrac%7BW%7D%7BQ_%7Bsupplied%7D%7D%20%5C%5C%5C%5C%20%5Ceta%20%3D%20%5Cfrac%7B150%7D%7B%7B180%7D%7D%20%5C%5C%5C%5C%20%5Ceta%3D0.833%20%5C%5C%5C%5C%20%5Ceta%3D%2083%20%5C%25)
The overall efficiency of this plant will be 83%.

Answer:
a convergent plate boundary
Explanation:
when one plate is oceanic, there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc
