Answer:
1.A. 88.89
2.B.6.3%
3.C.64.92%
Step-by-step explanation:
1.
to covert it into percentage multiply it with 100
then it becomes 88.888
rounding off to the nearest hundred it becomes 88.89
2. to convert into percentage multiply it with 100
therefore 0.063×100=6.3%
3. to find percentage
%= (no of students using mobile / total no of students )× 100
= ×100
=64.918
Rounding off to nearest hundred it becomes 64.92%
The depth of sun after 5 minutes is 809.82 feet
<em><u>Solution:</u></em>
A submarine dives at an angle of 13 degrees to the surface of the water
The submarine travels at a speed of 720 feet per minute
The figure is attached below
ACB is a right angled triangle
AB is the distance between surafce of water and submarine
BC is the depth of submarine
Let "x" be the depth of sun after 5 minutes
Therefore, distance between submarine and surface of water is:
Submarine dives at an angle of 13 degrees to the surface of the water
Therefore, angle A = 13 degrees
Now we have to find BC
By definition of sine,
Here, opposite = BC = x
hypotenuse = AB = 3600 feet
Thus, we get,
Thus the depth of sun after 5 minutes is 809.82 feet
