Ok so you would find the area of all of the shapes and then add it together. to find the area of the square you would multiply 8 by 8 to get 64. Then you would go on to finding the area of the four triangles which can be found by multiplying the base times the height to get 48. after you do this you would divide 48 by two to get 24 which is your area for the triangles. since there are four triangles you would multiply 24 by 4 to get 96. Finally to get the surface area you add 96 with 64 to get your surface area which is 160 in^2
Using the formula A = P(1 + r/n)^nt
P = 5,000
r = 8.5% or 0.085
n = 365
t = 13/365 (13 days out of a year)
A = 5,000 (1 + 0.085/365)^365*13/365
A = 5015.16
You will earn $15.16
Answer: she baked 1225 muffins.
Step-by-step explanation:
Let x represent the number of muffins that she baked.
She gave 4/11 of the muffins to her friends. This means that the number of muffins that she gave to her friends is 4x/11. The number of muffins remaining is
x - 4x/7 = 3x/7
She gave 4/7 of the remainder to the guests at the event. This means that the number of muffins that she gave to the guests at the event is
4/7 × 3x/7 = 12x/49
The number of muffins remaining would be
3x/7 - 12x/49 = 9x/49
She had 225 muffins left. It means that
9x/49 = 225
9x = 225 × 49 = 11025
x = 11025/9
x = 1225
