The number 10 is a hundred times greater than the number 0.1.
The fundamental concept of making the same number of additions repeatedly is expressed by the action of multiplication. The results of multiplying two or more integers are known as the outcomes, and the factors that are used in the multiplication are referred to as the factors. The process of the complementing system of the same number is made simpler by multiplication.
From the given data in the question,
0.1 is times 10
0.1 × x = 10
x = 100.

1 miles. How far did he travel?
Answer:
5 miles
Step-by-step explanation:
I'm assuming you meant 4 miles but 4 miles added to the one mile he walked is 5 miles.
Answer:
C: tan 60 = √3
Step-by-step explanation:
Let the adjacent part of the triangle be x and let the opposite side be y.
Thus, from trigonometric ratios;
x/10 = cos 60
We are given cos 60 = ½
Thus;
x/10 = ½
x = ½ × 10
x = 5
Similarly;
y/10 = sin 60
Now,from trigonometric relationship we know that; sin 60 = cos 30. Thus;
y/10 = cos 30
We are given cos 30 = (√3)/2
Thus;
y/10 = (√3)/2
y = 10 × (√3)/2
y = 5√3
Since it is a right angle triangle with one angle being 60°, it means the other one is 30° since sum of angles in a triangle is 180°.
Thus;
5/(5√3) = tan 30°
1/√3 = tan 30
Similarly;
5/10 = sin 60°
sin 60° = ½
Also;
tan 60 = (5√3)/5
tan 60 = √3
Also;
sin 30 = 5/10
sin 30 = ½
