Emily has 8 yellow marbles and 5 blue marbles write the simple ratio of blue marbles to yellow marbles

5 : 8

Step-by-step explanation:

The numbers 8 and 5 do not share any factors other than 1. This means that the ratio must be 5 : 8 since there is no way to simplify this without the use of decimals or fractions.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
