Find the number of students who like both peanut butter and jam. *
netineya [11]

Answer:

4 students

Step-by-step explanation:

As shown in the diagram, let U=[The total number of students questioned]

\implies n(U) = 10

A=[Those who liked peanut butter ]

\implies n(A) =18

B=[Those who liked jam ]

\implies n(B) = 10

x = those who like both peanut butter and jam.

Also 6 liked neither peanut butter nor jam.

From the diagram we can write the mathematical equation as follow and solve for x

30 = 18 - x + x + 10 - x + 6

\implies 30 = 34- x

We add x and subtract 30 to both sides.

\implies 30 - 30 + x = 34- x + x - 30

\implies x = 4

Therefore 4 students like both peanut butter and jam.

A plant food recipe calls for 1 1/2 cups of fertilizer for every 3 3/4 cups of water. If a gardener makes a 42 cup of plant food
bearhunter [10]

Step-by-step explanation:

Firstly we need to ratio the fertilizer to plant food:

1\frac{1}{2} : 3 \frac{3}{4}

Lets add these two values together:

1\frac{1}{2} + 3 \frac{3}{4} = 5 \frac{1}{4}

So now we know one of each, we can divide the above value into 42 to find out the amount:

42 ÷ 5\frac{1}{4} = 8

So this means that 8 portions of each can be used. This can calculate the full ratio by multiplying each ratio by 8:

(1\frac{1}{2} * 8) : (3 \frac{3}{4} * 8) =

12 : 30

You have not included the statements although I hope you can decide which statement is true via the explanation above, feel free to comment the different statements if need be.

Hope this helps!
