2:55 PM

Because 11:35 AM+55= 12:30 PM. Then 12:30 PM+2:25= 2:55 PM as a final answer

Please answer There is a bag filled with 3 blue and 5 red marbles. A marble is taken at random from the bag, the colour is noted

Misha Larkins [42]

Answer:

$\frac{15}{28}$ is the required probability.

Step-by-step explanation:

Total number of Marbles = Blue + Red $= 3 + 5 = 8$

Probability of getting blue $= \frac{3}{8}$

Probability of not getting a blue $=\frac{5}{8}$

To get exactly one blue in two draws, we either get a blue, not blue, or a not blue, blue.

<u>First Draw Blue, Second Draw Not Blue:</u>

1st Draw: $P(Blue) = \frac{3}{8}$

2nd Draw: $P(Not\:Blue)=\frac{5}{7}$ (since we did not replace the first marble)

To get the probability of the event, since each draw is independent, we multiply both probabilities.

$P(Event)=\frac{3}{8}\cdot \frac{5}{7}=\frac{15}{56}$

<u>First Draw Not Blue, Second Draw Not Blue:</u>

1st Draw: $P(Not\:Blue)=\frac{5}{8}$

2nd Draw: $P(Not\:Blue)=\frac{3}{7}$ (since we did not replace the first marble)

To get the probability of the event, since each draw is independent, we multiply both probabilities.

$P(Event)=\frac{5}{8}\cdot \frac{3}{7}=\frac{15}{56}$

To get the probability of exactly one blue, we add both of the events:

$\frac{15}{56}+\frac{15}{56}=\frac{15}{28}$

In the figure, Line BD bisecte angle ABC. <br><br>what is the length of line DC

NemiM [27]

BD is a angle bisector and Angle bisector theorem says
ratio of other sides of the triangle formed by bisector is equal
BA/AD=BC/CD
lets say AD is x so DC will be 4-x
3/x=4.5/4-x
x=1.6
AD=1.6units
so DC=4-x=4-1.6= 2.4 units

Kim needs to add a 6% saline solution to an IV bag that contains 20 cubic centimeters of 10% saline solution.

Sonja [21]

Let 'x' represent the volume of 6% saline solution
Let 'y' represent the volume of 8% saline solution

Form 2 equations.
Eq. 1: 20+x=y
Meaning 20 cm³ + x cm³=y cm³
Eq 2: 0.06x+0.1(20)=0.08y
Meaning: 6% of x + 10% of 20= 8% of y

Use substitution or elimination to solve this linear system. I used substitution.
Sub. Eq. 1 (20+x=y) into Eq. 2 (0.06x+0.1(20)=0.08y)
0.06x+ 0.1(20)=0.08(20+x)
0.06x+2+1.6=0.08x
-0.02x= -0.4
x=20

Substitute x=20 into equation 1 (you can also use 2 but in this case equation 1 is simpler)

20+x=y
20+20=y
40=y

To check, substitute x=20 and y=40 into equation 2

0.06x + 0.1(20)= 0.08y
0.06(20) +2 = 0.08(40)
1.2+2= 3.2
3.2=3.2

Therefore, Kim would need 20cm³ of 6% saline solution and 40cm³ of 10% saline solution to make 8% solution.

victor went for a run last week. It was 3.5 km long. Terrell went for 3 runs last week. eachrun was 1,250 m long. which person r

UNO [17]

First record information.
3.5 KM
3750= Terrell meters
Convert km to meters!
3.5--->3500 meters
3500 or 3750
3500 <3750
Victor ran more!
