Each dice has 6 sides

A bag of marbles contains 15 blue marbles and 25 green marbles. Which of the following shows the fraction of green marbles in th
hichkok12 [17]
In total, there are 40 marbles. 25 of those marbles are green. What I did was divide the number of green marbles by fourth, the total number of marbles. (25/40) You should come up with 0.625. Then you convert the decimal into a fraction. 5/8 is equivalent to 0.625. Thus, 5/8 of the marbles are green.

Hope this helps :)

Y and x have a proportional relationship, and y = 25 when x = 60. What is the value of x when y = 30?
dezoksy [38]
The equation governiong this relationship is y = kx.  Since y = 25 when x = 60,
25 = 60k, and k=(5/12).  Thus, the equation is   y = (5/12)x.

If y = 30, then 30 = (5/12)x.  Mult. both sides by 12/5 to obtain the value of x:

(12/5)(30) = 360/5 = 72

Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the un
Snowcat [4.5K]

Answer:

2nd car is running faster than the first car by 2.01 units.

Step-by-step explanation:

Let's assume that

  • the velocity of first car,

v_1\ =\ 20i\ +\ 25j

  • and the velocity of second car

v_2\ =\ 30i

=> speed of first car,

u_1\ =\ \sqrt{(20)^2+(25)^2}

      =\ \sqrt{400+625}

       =\ \sqrt{1025}

       = 32.01 units

and speed of second car,

u_2\ =\ \sqrt{(30)^2+(0)^2}

        = 30 units

u_2\ -\ u_1\ =\ 32.01\ -30

               = 2.01 units

Hence, 2nd car is running faster than the first car by 2.01 units.
