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.

Hi . I need help with the question below and the one in the picture.

Oliga [24]

Answer:

1) N5.00

2) N1.50

Step-by-step explanation:

1) 1/2+1/4+1/5=10/20+5/20+4/20=19/20=95%

That means the 4th girl received 5%.

25 is 5% of 500

500 Kobo is N5.00

2) He lost 55%, so they means he has 45% left.

67.5 is 45% of 150

(67.5/0.45=150)

150Kobo is N1.50

What's the area of the triangle below

LekaFEV [45]

Answer:

Option (a) is correct.

The area of triangle is 24 m²

Step-by-step explanation:

Given : A triangle with base 6 m and height 8 m

We have to find the area of the triangle and choose the correct option from the given options.

Area of triangle = $\frac{1}{2}\cdot base\cdot height$

Given Base = 6 m

and height = 8 m

Therefore, Area of triangle = $\frac{1}{2}\cdot 6\cdot 8=24$

Thus, The area of triangle is 24 m²
