Answer:
25
Step-by-step explanation:
3a=30... equation 1
2a+2b=30... equation2
equation 2 => a+b=15 ... equation 3
equation 1 => a = 10 ... equation 4
equation 4 & equation 3 => b = 5
5^2 = 25

Step-by-step explanation:
Use the Pythagoran Theorem
The width of the cloud is 12500 meters wide.
The situation forms a right angle triangle.
<h3>What is a right angle triangle?</h3>
Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using trigonometric ratios.
Therefore, the altitude is the opposite side of the triangle formed. The width of the cloud is the adjacent side of the triangle formed.
tan 10 = opposite / adjacent
Therefore,
tan 10° = 2200 / a
cross multiply
a = 2200 / tan 10°
a = 2200 / 0.1763269807
a = 12500 meters
Therefore, the width of the cloud is 12500 meters .

Answer: 
Step-by-step explanation:
Let d be the distance from Nadia's home to the grocery store.
Given : Nadia traveled uphill to the grocery store for 30 minutes at just 4 mph.
∵ 1 hour = 60 minutes.
Then, 
Since 
Then, 
Also, She then traveled back home along the same path downhill at a speed of 12 mph.
Then, Time taken to travel back home = 
Average Speed =
Hence, her average speed for the entire trip from home to the grocery store and back =
