For Sophia’s graduation party, several tables of the same width will be arranged end to end to form a serving table with a total

Andrew [12]

Answer:

The length is 16.1 ft and the width is 4.7 ft

Step-by-step explanation:

Let

x -----> the total length of the tables

y -----> the width of the tables

we know that

The area is equal to

$A=xy$

$A=75\ ft^{2}$

$75=xy$ -----> equation A

$x=3y+2$ -----> equation B

substitute equation B in equation A

$75=(3y+2)y$

$3y^{2} +2y-75=0$

Solve the quadratic equation by graphing

The solution is $y=4.7\ ft$

Find the value of x

$x=3(4.7)+2=16.1\ ft$

therefore

The length is 16.1 ft and the width is 4.7 ft

at 8:03 am there are 188 empty seats on the train. at 8:10 am there are 160 empty seats. the number of seats decreases by the sa

Vikentia [17]

Given:
8:03 = 188 empty seats
8:10 = 160 empty seat

188 - 160 = 28 empty seats
8:10 - 8:03 = 0:07 minutes

28 / 7 minutes = 4 empty seats per minute

8:00 - 8:03 = 3 minutes
3 minutes * 4 seats per minute = 12 seats

188 + 12 = 200 empty seats at 8:00

8:15 - 8:10 = 0:05 minutes
5 minutes * 4 seats per minute = 20 empty seats
160 - 20 = 140 empty seats at 8:15

200 - 120 = 80 empty seats
80 empty seats / 4 empty seats per minute = 20 minutes
120 empty seats at 8:20.

8:00 = 200 empty seats
200 / 4 = 50 minutes
8:00 + 0:50 = 8:50 is the time when there are no empty seats left.
