Answer:

The circumference of Mario's circle is 75 cm

Step-by-step explanation:

<u><em>The correct question is</em></u>

Joe drew a circle whose circumference is 25 cm. Mario drew a circle whose diameter is 3 times the diameter or Joe’s circle. What is the circumference of Mario’s circle?

we know that

All circles are similar

The ratio of the circumferences of two circles, is equal to the scale factor

Let

z ----> the scale factor

x ----> circumference of Mario's circle

y-----> circumference of Joe's circle

so

z=\frac{x}{y}

we have

z=3\\y=25\ cm

substitute the given values

3=\frac{x}{25}

solve for x

x=3(25)=75\ cm

therefore

The circumference of Mario's circle is 75 cm

A bag contains 3 red marbles, 2 blue marbles, and 5 green marbles. What is the probability of selecting a red marble, replacing
RUDIKE [14]

Answer:

3/20

Step-by-step explanation:

The total number of marbles is

3 red marbles+ 2 blue marbles+ 5 green marbles = 10 marbles

P(1st marble is red) = red marbles/total

                                =3/10

We replace the marble so there are still 10 marbles in the bag

P(2nd marble is green) = green marbles/total

                                =5/10 = 1/2

P(1st red, 2nd green) = P(1st marble is red) * P(2nd marble is green)

                                   =3/10 *1/2

                                    =3/20
