Answer:

4.5 cm.

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$

Upon substituting the measure of circumference in above formula we will get,

$28.3=2\pi r$

$r=\frac{28.3}{2\pi}$

$r=4.504084889500638\approx 4.5$

Therefore, the radius of circle O is 4.5 cm.

You get the same figure if you reflect it across a horizontal or vertical line through its center (reflectional symmetry).

You get the same figure if you rotate it 180° (rotational symmetry)

Each point corresponds to another equidistant from the center on a line through the center (point symmetry).

The 4th selection is appropriate.

A punch bowl contained 2 liters of ginger ale, 1 liter of orange juice, and 1 liter of cranberry juice. Select all of the statem

loris [4]

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Could negative two be used as a base to rewrite 32? 64?

Nataly [62]

$32=2^5-NO\ because\ (-2)^5=-32\\\\64=2^6-YES\ because\ (-2)^6=64$
