The circumference is 31.43 cm

The ratio of the circumference to the diameter is equal to 3:1

Step-by-step explanation:

Thed formular for the circumference of a circle is 2\pir or \pid

where d = diameter and r = radius

if d = 10 cm, and \pi = 3.143, then circumference of the circle can be given as

3.143*10 = 31.43 cm

The ratio of the circumference to the diameter can be given as 31.43:10

and that can be given as 3.143:1

This function normally has three algebraic terms, the x-square term, the x-term and the constant term.

Analysis:

The X-column values increases from -2 to 1, while the f(x) column which is the y-column increase from -9, until it gets to 1, where the value falls to -5.

A typical behavior of an inverted-v curve which is a quadratic curve.

If it were a linear function, as x values increase, y value would either keep increasing or decreasing, it does not change its orientation.

Answer:

  10,542,719

Step-by-step explanation:

The circle chart shows you that an estimated 49% of Australia's population has type O blood. Then the number expected to have type O blood is ...

  0.49 × 21,515,754 ≈ 10,542,719

_____

You can choose the correct answer by recognizing that 49% is very slightly less than 1/2, so the number with type O blood will be very slightly less than half of 21 million -- about 10.5 million.

svp [43]

Answer:

2 hours 11 minutes

Step-by-step explanation:

Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.

If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.

So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.

2.18 hours = 2 hours 0.18*60 minutes

0.18 * 60 = 11

Answer: 2 hours 11 minutes
