Answer:

The number of boys is 34   And The number of girls is 16

Step-by-step explanation:

Given as :

Total number of boys and girls =  50

Total amount to be divided between boys and girls =  Rs 41

The amount given to each boys = 90 paise = Rs 0.9

The amount given to each girls = 65 paise = Rs 0.65

Let The number of Boys = B

The numbers of girls = G

So, According to question

0.9 B + 0.65 G = Rs 41

And B + G = 50

Or, 0.9 B + 0.65 G = Rs 41          .......1

And 0.9 B + 0.9 G = 45                 ......2

Now, (  0.9 B + 0.9 G ) - ( 0.9 B + 0.65 G ) = 45 - 41

Or,      0.25 G = 4

∴                  G = \frac{4}{0.25} = 16

And The number of boys = B = 50 - G = 50 - 16 = 34

Hence  The number of boys is 34   And The number of girls is 16   Answer

2 trains leave the station at the same time. Train A is traveling 16 miles slower than train B. The two trains are 720 miles apa
Ber [7]

Answer: the rate of speed for train A is 66 miles per hour.

Step-by-step explanation:

Let x represent the speed of train B.

2 trains leave the station at the same time. Train A is traveling 16 miles per hour slower than train B. This means that the speed of train A would be x - 16 miles per hour.

The two trains are 720 miles apart after 4 hours. It means that both trains traveled a total distance of 720 miles in 4 hours.

Distance = speed × time

Distance travelled by train A after 4 hours is

4(x - 16) = 4x - 64

Distance travelled by train B after 4 hours is

4 × x = 4x

Since the total distance travelled by both trains is 720 miles, then

4x - 64 + 4x = 720

8x = 720 - 64 = 656

x = 656/8 = 82 miles per hour

The speed of train A would be

82 - 16 = 66 miles per hour.

Find the domain of the funtion 4/x-7
dedylja [7]
Domain means which values the function can have which make it true or Possible to solve

So all you got to do is set the denominator = to 0 and solve for x
You will get x=7

4/(7-7) is not possible

So x cannot equal to 7 because you cant divide a number by 0!
