Answer:
C) 11
Step-by-step explanation:
65/5=13
91/7=13
182/14=13, therefore
143/13=11
Answer:
, 12,
, 10
Step-by-step explanation:



so
= 10
12
= 10.66
and 10
Because saying 5 over 1/2 is saying 5 divided by 1/2 which is the same as saying 5 * 2
8 over 3/4 is 8 divided by 3/4 which is 8 * 1.33.
A fraction is division. If you mean 5 and 1/2 as well as 8 and 3/4 then remove 5 and 1/2 from the answer.
Answer: 20 feet by 20 feet.
Step-by-step explanation:
1. You know that
is the original measure of one side. Since it is a square, all its sides are equal.
2. Therefore, to solve the problem you only need to solve for
, as you can see below:
- You have that:

- Then, you obtain the following quadratic equation:

- Apply the Quadratic formula to solve it:

- Then, you obtain:

3. The dimensions cannot be negative, therefore, the answer is: 20 feet by 20 feet.
So a triangular prisim is like a triangle stacked on top of x number of identical triangles making a height, like a piece of paper made into a stack
so
basically find the area of each side and add
look at diagram/attachment
find area of triangle
1/2 b times h= area of 1 triangular face
multiply by 2 because 2 sides so 1/2 times 2 b times h=b times h
then 3 other sides
find area of each side and add
areas=(H times B)+(H times c)+(H times a)
so SA=(b times H)+(H times B)+(H times c)+(H times a)
