4 students
Step-by-step explanation:
As shown in the diagram, let U=[The total number of students questioned]
A=[Those who liked peanut butter ]
B=[Those who liked jam ]
x = those who like both peanut butter and jam.
Also 6 liked neither peanut butter nor jam.

Step-by-step explanation:
Let
b -----> the base of parallelogram
h ----> the height of parallelogram
we know that
The area of parallelogram is equal to
so
substitute the value of b
---->inequality that represents all possible values of h
Step-by-step explanation:
Firstly we need to ratio the fertilizer to plant food:
Lets add these two values together:
So now we know one of each, we can divide the above value into 42 to find out the amount:
42 ÷ = 8
So this means that 8 portions of each can be used. This can calculate the full ratio by multiplying each ratio by 8:
=
12 : 30
