The tent shown below has fabric covering all four sides and the floor. What is the minimum amount of fabric needed to construct
fenix001 [56]

Answer:

I believe the answer is 152 ft

Step-by-step explanation:

On the side, you would find the area of the square (8x5=40). Then, you would find the area of the triangular front (6x4=24 divded by 2 so it's 12). There are two sides of each, so 24+80=104. Then, you dfind the aarea of the bottom square (6x8=48) and add them all together to make 152

Please help explanation if possible
Eva8 [605]

Answer:

612 adults

361 students

Step-by-step explanation:

To solve this question, set two equations:

Let x be number of adults and y be number of students.

As there are in total 937 people, the equation would be the sum of both adults and children:

x+y=937

x=937-y  ...... ( 1 )

As the total sale amount is $1109, the equation would be to add up the ticket fee:

2x+0.75y=1,109  ...... ( 2 )

Put ( 1 ) into ( 2 ):

2(937-y)+0.75y=1,109

1874-2y+0.75y=1,109

-1.25y=-765

y=763/1.25

y=612

Put y into ( 1 ):

x=973-612

x=361

Therefore there are 612 adults and 361 students.
