Answer:

12.2..22.2.2.2..22.2.2.2.2.2.2.2.2.2..2.2

Step-by-step explanation:

Solve. x/3 - 12 = 24

Answers

$(x)/(3) - 12 = 24 \n \n (x)/(3) = 24 + 12 \n \n (x)/(3) = 36 \n \n x = 36 * 3 \n \n x = 108 \n \n$

The final result is: x = 108.

The Answer is 108

x/3 - 12 = 24
+ 12 +12
x/3 = 36
*3 *3
x=108

Aldrin and Jan are standing at the edge of a huge field. At 2:00 p.m., Aldrin begins to walk along a straight path at a speed of 3 km/h. Two hours later, Jan takes a straight path at a 608 angle to Aldrin’s path, walking at 5 km/h. At what time the two friends be 13km apart?

Answers

Answer: After 2:29 hours both Aldrin and Jan will be 13 km apart from each other.

Time at that instant will be : 4:00 pm + 2.29 hours= 6:29 pm

Step-by-step explanation:

According to the figure:

Ab= c = 13 Km

AC = b = $distance= speed* time =5* t$ =5t Km

After two hours the distance covered by the Aldrin say till point D :

$distance=speed* time=3km/hr* 2 hrs=6 Km$

Since, we are interested in determining the time at which Aldrin and Jan both 13 Km apart. For that Aldrin Additional distance covered by the Aldrin from point D to B is :

$distance=speed* time= 3km/hr* t=3t Km$

CB= a = CD+DB= 6+3t

We will apply Laws of cosines:

$C^2=A^2+B^2-2AB* Cos\theta$

$(13)^2=(6+3t)^2+(5t)^2-2(5t)(6+3t)Cos 60^o$

$19t^2+6t-133=0$

On solving the the above equation by quadratic formula we get two values of 't'

1) t = 2.49 hours , 2) t = -2.80 hours

Since,time cannot be in negative so we will ignore the negative value of t

t = 2.49 = 2:29 hours ,(0.49 hour=0.49 × 60 min=29.4 min)

After 2.49 hours after the walking of Jan. Both Aldrin and Jan will be 13 km apart from each other.

Time at that instant will be : 4:00 pm + 2:29 hours= 6:29 hour

A pie was cut into 8 equal slices if Ruben ate 3/4 of the pie how many slices did he eat?

Answers

Answer:

Ruben ate 6 pieces out of 8.

Step-by-step explanation:

We will understand 3/4 first. If we divide a pie into 4 pieces then Ruben ate 3 pieces of pie.

Further If we divide these 4 and 3 pieces to 8 and 6 then Ruben will eat 6 pieces out of 8.

Now we will show this mathematically

$(3)/(4)=(3)/(4)* (2)/(2)=(3*2)/(4*2)=(6)/(8)$

Ruben ate 6 pieces out of 8.

You can just set 3/4=X/8, when you multiply the 4 through you get 3=4x/8 which can be simplied to 3=x/2, multiply the 2 over and you have 6=x.
