Answer:

45-21cm

1-x

\frac{21}{45}

\frac{21}{45}  - 60 \\ x - 1

\frac{21}{45}  \times  \frac{1}{60}  =  \frac{21}{2700}

\frac{21}{2700}  \times 50 \times 72 =  \frac{75600}{2700}  = 28

they can construct 28cm

Explain why an inverse variation function is not the best model for the data set​
dmitriy555 [2]

Answer: The cause of exponential decay. Sowwy if im wrong

Step-by-step explanation:

An inverse variation function is not the best model because the data points show an exponential decay. The fact that this is true for ALL of the points shown indicates we have an inverse variation of the form x*y = k where k = 60 in this case. ... For any inverse variation, as x increases, y will decrease (and vice versa).

Martha will build a pool in her backyard. She wants the pool to have a rectangular shape
Ivan

9514 1404 393

Answer:

  C.  161.459 square feet

Step-by-step explanation:

In feet, the dimensions of the pool are ...

  (5 m)(3.28084 ft/m) = 16.4042 ft

  (3 m)(3.28084 ft/m) = 9.84252 ft

Then the area of the pool is ...

  (16.4042 ft)(9.84252 ft) = 161.458666584 square feet

  about 161.459 square feet

_____

<em>Additional comment</em>

If you consider that a square meter is slightly less than 11 square feet, the pool area can be estimated to be (5 m)(3 m)(11 ft²/m²) = 165 ft². This is close enough to point you to the correct answer choice.
