There are 10 marbles in a bag. 1/5 are red and the others are blue. What is the ratio to blue marbles.
Irina-Kira [14]

Answer:

Ratio = 1 : 4

Step-by-step explanation:

Total marbles = 10

Given 1/5 is red, that is 1/5 of the total marbles are red

                                                            \frac{1}{5} \ of \ 10 = \frac{1}{5} \times 10 = 2

Therefore , 10 - 2 = 8 marbles are blue.

Ratio of red marbles to blue marbles

                                    \frac{2}{8} = \frac{1}{4} = 1 : 4

Which geometric object is defined as the set of all points in a plane at a given distance from a given point
hodyreva [135]

Answer:

Circle

Step-by-step explanation:

This object is what we call "circle". All the points in the circle are at the same distance from a given point which is the center of the circle. Moreover, the distance between the center and every point on the circle is called "radius". Higher values for the radius imply points at a higher distance from the center.

Additionally, we can calculate the perimeter of the circle, or the circumference, with the following formula:

circumference = 2*(radius) pi

Where pi is an irrational number usually used as 3.14.

If you have doubts, try to draw a circle and measure the distance between the center and any point on the circle.
