The large community college has 76 professors and 212 lecturers
<u>Solution:</u>
Given that,
Total number of faculty = 228
Let, the number of professors be p, then the number of lecturers will be 228 – p
They have 5 professors for every 14 lecturers.
Then, ratio of professors to lecturers is 5 : 14
Expressing the ratio as fractions, we get,
Plug in the values of number of professors and lecturers
So, community has 76 professors, then, it will have 288 – 76 = 212 lecturers.
Answer:
Step-by-step explanation:
Given
Area of a floor = 2040ft²
If Its length is 36ft. longer than its width, then L = W+36
Area = LW
L is the length
W is the width
A < W(W+36)
2040 < W²+36W
0<W²+36W-2040
W²+36W-2040 >0
W = -36±√36²-4(-2040)/2
W = -36±√1296+8160)/2
W = -36±√9456/2
W = -36±97.25/2
W = -36+97.25/2
W = 61.24/2
W > 30.62ft
Since L = W+36
L > 30.62+36
L > 66.62ft
The width of the floor is 30.62ft
The length is 66.62ft
The mathematical sentence would represent the given situation is the width is greater than 30.62ft while the length must be greater than 66.62ft
The possible dimension of the floor is 31ft by 67 ft
The possible areas is 31*67 = 2077ft²
It won't be realistic to get an area of 144sqft because the initial area is greater than 144. Hence the feasible area will be greater than 2040ft²
It's quite easy to calculate - one meter is billion nanometers (1 000 000 000), so:
- 1.7 meters = 1 700 000 000 nanometers
- 1.52 meters = 1 520 000 000 nanometers
