Obviously from a test.

Cross multiply.

16:1
2000:x

2000 = 16x
/16        /16
  125 = x

Therefore there must be 125 teachers to support 2000 students.

Let f(x) = x2 - 16. Find f-1(x).
Arisa [49]
f(x)=x^2-16

To find f^{-1}(x), (the inverse of the function) you need to first replace the f(x) with y...
y=x^2-16
Then switch the x and the y.
x=y^2-16
Solve for y.
x+16=y^2
Take the square root of each side...
\boxed{y=\pm\sqrt{x+16}}

Tiles (6" by 6") can be installed at the rate of 50 per worker hour. The floor of a large lobby area (80’ by 40’) is to be cover
RideAnS [48]

Answer:

Step-by-step explanation:

Tiles (6" by 6") can be installed at the rate of 50 per worker hour. Since the tile is a square, its area is

L^2 = 6^2 = 36 inches square

So in an hour, a worker installs 50 tiles whose area is 36 inches square. Total square meters installed per hour will be 50 × 36 = 1800 inches square per hour.

If three workers are assigned to this task, their work rate will be

1800 × 3 = 5400 inches square per hour.

The floor of a large lobby area (80’ by 40’) is to be covered with these tiles. We would convert from feet to inches.

1 foot = 12 inches

80 feet = 80 × 12 = 960 inches

40 feet = 40 × 12 = 480 inches

Area of the lobby = 90 × 480 = 460800 inches square.

If the 3 workers install 5400 inches square in 1 hour,

Then then they will install 460800 inches square in

460800/5400 = 85.33 hours

Converting to the nearest whole day, it becomes

85.33/24 = 3.55

Approximately 4 days

Please help me .. I really need help with this ASAP ​
morpeh [17]

Given:

Number of flower pots = 6

To find:

The number of ways of the gardener to arrange the flower pots.

Solution:

Number of ways to arrange n items is n!.

So, the number of ways to arrange 6 pots is:

6!=6\times 5\times 4\times 3\times 2\times 1

6!=720

Therefore, there are total 720 ways of the gardener to arrange the flowerpots.

How to calculate concentration with just the absorbance and % transmittance measurements from a spectrometer? ​
Natali [406]

Answer:

A=ε*l*c

A= 2- log₁₀ % T

Step-by-step explanation:

There is a linear relationship between the concentration of a sample and absorbance according to Beer-Lambert Law.

A=ε*l*c

where;

A=absorbance

ε=absorption coefficient

l=path length

c=concentration

Because % transmittance is transmittance value multiplied by 100 then, the equation that will allow us calculate absorbance from % transmittance value will be;

A= 2- log₁₀ % T where T is transmittance.
