Answer:
40
Step-by-step explanation:
First we need to subtract the 50 students enrolled in English class.
150 - 50 = 100
Next, let's add the mathematics students and the physics students.
80 + 60 = 140
Then we subtract the total amount of mathematics and physics students by the total number of students.
140 - 100 = 40
Therefore, there are 40 students who take both mathematics and physics.

Ratio
------------------------------------------------
3 : 1
------------------------------------------------
Find total parts
------------------------------------------------
3 + 1 = 4
------------------------------------------------
Split the 32 according to the parts
------------------------------------------------
4 parts = 32
1 part = 32 ÷ 4
1 part = 8
3 part = 8 x 3 = 24
------------------------------------------------
Split the 32 into the ratio
------------------------------------------------
24 : 8
------------------------------------------------
Answer: 24 : 8
------------------------------------------------
Answer:
Paul might have written the expression 
.
Step-by-step explanation:
Given:
Length of the leg 1 = a
Length of the leg 2 = b
Hypotenuse = h
We need the expression Paul has written:
Solution:
Now we know that;
The figure sketched by Paul is a right angle triangle.
Now by Pythagoras Theorem which states that;
"The square of the length of the hypotenuse is equal to sum of the square of the length of the legs."
equation can be framed as;
Hence Paul might have written the expression .
Answer:
1 inch to five hundred feet
Its just like fractions, which ever one is lower has the greater value in ratio
