To clean windows of skyscrapers, some companies use a carriage. A carriage is mounted on a railing on the rook of a skyscraper a

nd moves up and down using cables. A crew plans to start at the 12th floor and move the carriage down as they clean the windows on the west side of a building. If the crew members clean windows at a constant rate of 0.75 floor per hour, the absolute value function f(t) = 0.75t-12 represents the number of floors above ground level that the carriage is after t hours. Graph the function. How far above ground level is the carriage after 4 hours?

Answer: -9 OR 15 (See explanation)

Step-by-step explanation:

Substitute 4 for t since t represents hours:

0.75t - 12 --> 0.75(4) - 12 =

3 - 12 =

-9

Something seems off, if you meant to put +12 instead of -12, then the answer is 15. Hope this helps, please consider making me Brainliest.

suppose the divisor and the dividend of a division problem are both fractions between 0 and 1, and the divisor is greater than t
Virty [35]

Divisor and Dividend are fractions lying between 0 and 1

Also, Divisor > Dividend

⇒ A smaller number is being divided by a larger number

Whenever a smaller number is divided by a larger number, the quotient is less than 1

E.g. Let divisor be \frac{4}{5} and dividend be \frac{2}{5}

\frac{4}{5} ÷ \frac{4}{5} = \frac{1}{2}, which is less than 1

Hence, the answer is that the quotient will be less than 1

If the sum of interior angle measures of a polygon is 720, how many sides does the polygon have?
NISA [10]
Since the interior is 720 divide it by 180 and you will get 4 so 4=n-2 where the n means number of sides. Move the 4 over to n=4+2 and you get n=6

A person breathes 2.5 x 10^-4 in about cubic meters of air per second. How long does it take to breathe in 2.5 cubic meters of a
Ipatiy [6.2K]

Answer:

10⁴ seconds

Step-by-step explanation:

Given that,

A person breathes 2.5\times 10^{-4} in about cubic meters of air per second.

We need to find time taken to breathe 2.5 cubic meters of air.

In 1 sec = 2.5\times 10^{-4} m³ of air breathe

Let in x seconds, 2.5 m³ of air taken by the person.

x=\dfrac{2.5}{2.5\times 10^{-4}}\\\\x=10^4\ s

Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.

Answer:

The length of the long side is 147 ft

The length of the short side is 30 ft

Step-by-step explanation:

L=5s-3

s= 324-2L

324=2(5s-3)+s

distribute

324=10s-6+s

simplify

324=11s-6

add 6 to both sides

330=11s

divide by 11

30=s

Plug in the s value to determine the length of the long side
