The number of ways they can be seated in a row if both families want to sit together is 2 ways
Given that two families with four people in each family go to a movie theater, in order to determine the number of ways they can be seated in a row if both families want to sit together
We will use the permutation rule since it is about the arrangement.
We will take 4 people as 1 group and the other 4 people as another group.
If the groups are to sit together, the number of ways this can be done is 2!
2! = 2 * 1
2! = 2ways
This shows that the number of ways they can be seated in a row if both families want to sit together is 2 ways

In order to subtract 2.34 from 20, the best method is using column subtraction.
To do this, we put the main number on top, and the number we are taking away underneath it.
When we set it out, we need to make sure that all the columns line up properly, the units in one line, tens in the other etc.
If taking decimals from a whole number, I would always recommend putting '0's after the decimal point for place value.
For the layout, see below:
20.00
- 2.34
Now, as we cannot subtract 4 from 0, we must begin borrowing from the neighbours.
As 2 is the nearest number, we take one from there and move it next door
1¹0.00
Do the same again, 10 becomes 9
19.¹00
And one last time
19.9¹0
Now subtract 2.34 from 19.9¹0
19.9¹0
- 2.34
10 - 4 = 6
9 - 3 = 6
9 - 2 = 7
1 - 0 = 1
17.66

Hope it makes sense, once you get your head round it you'll be fine
Answer:
56.6m
Step-by-step explanation:
Using SOH = opp/hyp
Where θ = 45°
Hpy = 80m
Opp = ?
Sin θ = opp/hpy
Sin 45 = opp/ 80
Sin 45 × 80 = opp
0.7071 × 80 = opp
Opp = 56.568
~ 56.6m
Hence the height of the top of the tree is 56.6m
Because Marty's pizza is bigger than Luis'.
Given :
Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug.
To Find :
How many mugs did Jack make if he had 28.88 lbs of clay left over.
Solution :
Clay required to make 1 mug, r = 0.72 lbs.
Amount of clay left after making sculpture is, T = 28.88 lbs.
Now, number of clay mug Jack can make is :
Since, number of mug cannot be in decimal, so we take the floor value.
Therefore, number of mug that can be prepared is 40 .
