Answer:
1099/11=99.9
since you can't have 99 boxes, you round to 100 boxes.
you will need 100 boxes.
Looking at the top half, we can see a triangle formed by ABC.
The area of a triangle is found by multiply 1/2 x base x height.
The height would be 1/2 of the overall height of the shape so 14.3 /2 = 7.15.
The area of the top half = 1/2 x 7.15 x 17.2 = 61.49
Since the bottom half is identical to the top half, multiply that area by 2 for the total area:
61.49 x 2 = 122.98 square feet.

Answer:
Step-by-step explanation:
Alexa earns $33,000 in her first year of teaching and earns a 4% increase in each successive year. This means that for each year, her income is 104% of the previous year. So the rate of increase is 104/100 = 1.04. This rate is in geometric progression. The formula for the sum of n terms of a geometric sequence is expressed as
Sn = a(r^n - 1)/r-1
Where
Sn is the nth term
a is the first term
n is the number of terms.
r is the rate or common ratio
From the information given,
a = 33000
r = 1.04
The formula for Alexis total earning over n years will be
Sn = 33000(1.04^n - 1)/(1.04 - 1)
Her earnings for the next 15 years would be
S15 = 33000(1.04^15 - 1)/(1.04 - 1)
S15 = 33000(0.8009) / 0.04
S15 = $668167.50
