Answer: 4
<u>Step-by-step explanation:</u>
To fit the maximum amount of people in one row, you would have 3 couples and 1 single = 7 parents.
If we continue the maximum amount of people for 7 rows, we get 49 parents seated.
Since a total of 54 parents are seated, that leaves 54 - 49 = 5 parents remaining to be seated in the last row. These parents can be seated as 2 couples and 1 single. If you put the single at the end of the row, there will be 4 seats between the couple and the single.

Answer/Step-by-step explanation:
Recall: if two figures are similar, we know that the ratio of their areas = the square of the ratio of their corresponding sides
Apply this knowledge to solve the problems given.
✔️Problem 1 (4-sided polygon):
Let the missing area be x cm²
Therefore,
Multiply both sides by 9
x = 9*4
x = 36 cm²
✔️Problem 2 (3-sided polygon):
Let the missing area be y cm²
Therefore,
Multiply both sides by 240
y = ¹/16 × 240
y = 15 cm²
✔️Problem 3 (5-sided polygon):
Let the missing area be z cm²
Therefore,
Multiply both sides by 40
z = 90 cm²
A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
Answer: greeting cards= 44 , gift wrap= 161
Step-by-step explanation:
4(gift wrap)+10(greeting cards)=1084
4(161) + 10(44)=1084
(23π/20) rad * 180°/(π rad) = (23π*180°)/(20π) = 9*23° = 207°
