The fraction of the remaining marbles in the bag will be blue is 6/17.

<h3>What fraction of the remaining marbles in the bag will be blue?</h3>

The first step is to determine the initial number of marbles in the bag:

Initial number of red marbles in the bag : (5/8) x 240 = 150

Initial number of blue marbles in the bag : (2/8) x 240 = 60

Initial number of green marbles in the bag : 240 - 150 - 60 = 30

Number of red marbles remaining after 1/3 is removed = (1 - 1/3) x 150

2/3 x 150 = 100

Number of green marbles remaining after 2/3 is removed = (1 - 2/3) x 30

1/3 x 30 = 10

Total number of marbles now in the bag : 100 + 10 + 60 = 170

Fraction of blue marbles = 60 / 170 = 6/17

Lynna [10]
Well the angles should all equal 360. Since you know 90 and 160 then 360-90-160=110. Angle 2 is 90* so 110-90=20 so angle 4 is 20. Angle 2+ angle 4: 90+20=110 or C :)

Answer:

E. 31

Step-by-step explanation:

Add the values together.

4 (2/6) + 3 (3/6) + 2 (3/6) = 9 (8/6) or 10 (1/3)

multiply 10 by 3 to find how many thirds there are and add 1 to that number for the extra 1/3.

Jay's mean score for four quizzes is 99. ​ ​His scores for the first three quizzes are 88 , 55 , and 99. ​ ​What is Jay's score
Katarina [22]

Answer: 154

Step-by-step explanation:

The mean is calculated by adding up all the numbers and dividing by the number of observations added up.

The above can therefore be expressed as:

(88 + 55 + 99 + x) / 4 = 99

242 + x = 99 * 4

242 + x = 396

x = 396 - 242

x = 154
