Answer:
Step-by-step explanation:
125 % can be expressed as decimal as
Rule in changing Percent to decimal
a) Divide a percent by 100
b) Remove percent sign
example
30%
= 3/10
45 %
<span>Sales
tax on a jacket with the price of 725 dollars.
the sales tax rate is 7%
=> Convert 7% into decimals
=> 7% / 100 = 0.07
Now, multiply the 0.07 in 725 dollars
=> 50.75
thus the total tax rate of the jacket price is 50.75
Now, let us calculate the total amount that you will be paying
=> 725 + 50.75
=> 775.75 = the total amount to be paid.</span>

Step-by-step explanation:
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
