If your school is 30 feet tall and 1 feet is 1.26 cm, you would multiply 30 and 1.26 to get the height of the scale model which is 37.8 cm. Then, if each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks you need to build the school, which is 6.
The model will be 6 toothpicks tall.
area = L x w
42 = 6 x w
w=42/6 = 7
rectangle is 6 x 7
square would be 6 x 6 = 36 square feet
36/42 = 0.857 = 85.7% ( Round answer if needed)

The sum of the amounts of change in the bacteria after the seventh day is 6554.
<h3>What is the geometric sequence about?</h3>
The sequence are:
2, -8, 32, -128
Note that a first term of:
(a) of 2
A common ratio (r) of -8/2 = -4.
So the sum of n terms is said to be:
Sn = a1·(r^ n -1)/(r -1)
For the given sequence, the sum of 7 terms is said to be:
S7 = 2·((-4)^7 -1)/(-4-1)
= 2(-16384/-5)
= 6554
Therefore, The sum of the amounts of change in the bacteria after the seventh day is 6554.
