You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x

Licemer1 [7]

Answer: There are 1436 bricks that he will need to make a brick wall.

Step-by-step explanation:

Since we have given that

Dimensions of a brick wall is given by

Length = 14.5 feet

Width = 0.5 feet

Height = 5.5 feet

Dimensions of a brick is given by

Length = 6 inch

Width = 4 inch

Height = 2 inch

We need to find the number of bricks :

So, Number of bricks is given by

$\text{ Number of bricks }=\frac{\text{ Volume of brick wall }}{\text{ Volume of brick}}\\\\=\frac{14.5\times 5.5\times 0.5\times 12\times 12\times 12}{6\times 4\times 2}\\\\=1435.5\\\\=1436$

Hence, there are 1436 bricks that he will need to make a brick wall.

A graduate school plans to increase its enrollment capacity by developing its facilities and the programs it offers. Their enrol

kap26 [50]

Answer:

4.4 years

Step-by-step explanation:

Next time, please share the answer choices.

In this case, the beginning enrollment capacity was 120. The rate of increase was 3.00, the terminal enrollment cap 3,240. We let t represent the number of years:

3,240 students = (120 students)(3.00)^t

We need to solve this for t, the number of years required before enrollment will hit 3,240 students.

Solve 3240 = 120(3)^t for t:

Divide both sides by 120, obtaining 27.

Then we have

127 = 3^t

Logarithms are the best tool to use here to find t. Take the natural log of both sides:

log 127 = t log 3. Solving for t: t = (log 127) / (log 3), or t = 2.104 / 0.477 = 4.41

Thus, starting at 120 students, enrollment reached 3,240 students in 4.4 years.
