0.83333 and the 3 repeating would be 5/6 as a repaeating decimal remember it goes on and on.
Answer:
j=10.8
Step-by-step explanation:
First, you want to get rid of that 1, so to do that, you add 1 to each side, so you have j/4=2.7. Next, to get rid of the division, you need to multiply by 4 instead, so if you multiply each side by 4 to cancel out the division, you're left with j=10.8
Answer:
The trains will meet in 3 hours.
Step-by-step explanation:
The initial distance between the trains was 710 km, but since the cargo train started an hour before the passenger train, it has already covered some distance towards it. The distance the cargo train has covered is simply the product of its speed 
and the time taken 
:
So the distance left between the trains is the starting distance minus this distance:
Now both trains are travelling towards each other, this means the rate at which the distance that is being covered is equal to the sum of the speeds of the trains:
Now that we have the speed, it is easy to calculate the amount of time it will take for the trains to meet:
Thus the cargo train and the passenger train will meet in 3 hours.
Answer:
Answer for 4th question
b = 7
Answer for 5th question
area= 99sq.in
Step-by-step explanation:
4. area of parallelogram= base × height
28= b × 4
b= 28/4
b = 7
5. area of parallelogram= base × height
area= 9 × 11
area= 9 sq.in
Answer:
The value of element (1,1 )in matrix X is x =( m-4)
Step-by-step explanation:
Here, solving the given matrix equation, we get
Let X = {x,y}
Now, by matrix multiplication:
x + 2y = m
and my = 2 m
⇒ y = 2
Now, if y = 2,
⇒ x + 2(2) = m
or, x = m -4
Hence, (1,1) entry of X is x =( m-4)
