Area of rectangle = length * width

A = (2 2/9 yd) * (3 2/5 yd)

Convert both mixed numerals into fractions.

A = (20/9 yd) * (17/5 yd)

A = (20 * 17)/(9 * 5) yd^2

A = (4 * 17)/(9) yd^2

A = 68/9 yd^2

A = 7 5/9 yd^2

How would you do this???
Kobotan [32]

Answer:

8.3 L/s

Step-by-step explanation:

To find the answer you need to find the slope also known as the rate of change. When you find slope it is always change in y over change in x.

\frac{399-150}{40-10}

Then simplify

\frac{249}{30}

Then divide to get your slope/average rate of change

\frac{249}{30} = 8.3

An airplane is flying at an altitude of 33,000 feet. It needs to reduce its altitude by 6% to avoid some turbulence. After it pa
Tema [17]

Step-by-step explanation:

100% = 33,000 ft

1% = 100%/100 = 33000/100 = 330 ft

6% = 1% × 6 = 330 × 6 = 1980 ft

that means the plane has to go down 1980 ft to

33,000 - 1980 = 31,020 ft

and then it goes up by 5000 ft :

31,020 + 5000 = 36,020 ft

that is the final altitude.
