Surface are just means that you need to find the area of every face, then add.
TO find the Area of the rectangle do 16*8 = 128
For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28
There are four sides total and two triangles and two rectangles so 28+28+128+128= 312
SO the surface area is 312 in cubed
Answer:
Option c (7.8) is the correct alternative.
Step-by-step explanation:
The given points are:
(x₁, y₁) = (2, -3)
(x₂, y₂) = (-4, 2)
As we know,
The distance between two points will be:
= 
On substituting the values, we get
= 
= 
= 
= 
= 
= 
Their sum can be both equal, or greater. If you have 3/8 and 6/8, you would get 9/8 or 1 and 1/8. Which is greater than 1. Also if you add 2/6 and 4/6, you get 6/6 or 1. proving that both are possible.
Answer:

Step-by-step explanation:
Total number of the students in the pep squad = 12 students
The number of the students wearing white shirts = 3 students
The number of the students wearing blue shirts = 6 students
Either white or blue shirts indicate that the students wearing white shirt or blue shirt.
Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students
So,
The fraction is:-
