Given :
A hostel of 500 boys has provisions for 4 days.
To Find :
If the provisions were continued for 20 days, how many students have gone out of the hostel.
Solution :
Let, number of students left after 20 days are x.
Now, provisions are given by :

Also, provisions remains same.
So, initial provision = final provision

Therefore, 100 students have gone out of the hostel.
Hence, this is the required solution.
The shortest length you will need to reach the tower window if the ladder is placed 10 feet from the base would be 37.36 feet
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let l represent the shortest length you will need to reach the tower window, hence:
l² = 36² + 10²
l = 37.36 feet
The shortest length you will need to reach the tower window if the ladder is placed 10 feet from the base would be 37.36 feet

Answer:
The m∠ U is 72°.
Step-by-step explanation:
Given:

To find :

Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as

Here we have n = 5 on substituting the values we get

Therefore,
m∠ U is 72°.
Answer:
6 degrees
Step-by-step explanation:
x + 12x + 17x = 180
x = 6
The angles are 6 : 72 : 102 so the smallest is 6 degrees.
Answer:
B, C
Step-by-step explanation:
Since y=0, you are looking for equations such that 10 times the coefficient of x is the constant in the equation.
