Okay Abrahammontiel1, the thing you must remember is any thing that is 5 or over must be rounded up and anything lower must be rounded down.
Example:
$2.30
since we want to round to the nearest dollar we look at the digit behind the whole dollar, which in this case is 0.3
and since it's lower that 0.5 we must round down
So it will look like this: $2
If we had a number like $4.72
we would look at the 0.7
and since it is greater that 0.5 we would round up so that it would equal $5
The equation can be:5*13=65
Answer:
$4000
Step-by-step explanation:
Let B represent amount invested in account 'b'.
We have been given that an amount of $12,000 that Boris invested in fund a returned a 6% profit.
So the profit earned from fund 'a' would be 
.
We are also told that the amount that he invested in fund b returned at 2% profit. So the profit earned from fund 'b' would be 
.
Further, both funds together returned a 5%. We can represent this information as:
Now, we will equate profit earned from account 'a' and 'b' with profit earned from both accounts as:
Therefore, Jason invested $4000 in fund 'b'.
The triangular pyramid is made of 4 congruent triangles. They all have the same shape and size, so they have the same area. The area of one triangle is
A = b*h/2
A = 5*4.3/2
A = 10.75
So four of them lead to a total surface area of 4*10.75 = 43 square meters
--------------------------
The rectangular prism has the dimensions
L = 5
W = 5
H = 4.3
The surface area is found through the formula below
SA = 2*(L*W+L*H+W*H)
SA = 2*(5*5+5*4.3+5*4.3)
SA = 136
--------------------------
So far we found that
surface area of pyramid = 43 square meters
surface area of prism = 136 square meters
Dividing the values, we get 136/43 = 3.16279 approximately. The result is not equal to 2, so Susan's statement is not correct. The prism has more than twice the surface area of the pyramid
