For this case we are going to define the following variable:
 x: time in minutes
 We write the linear function that represents the problem:
 t (x) = (14/4) x + 7
 For x = 6 we have:
 t (6) = (14/4) * (6) + 7
 t (6) = 28 ° C
 For x = 11 we have:
 t (11) = (14/4) * (11) + 7
 t (11) = 45.5 ° C
 Answer:
 
t (6) = 28 ° C
 
t (11) = 45.5 ° C

Vitek1552 [10]

Answer:

32

Step-by-step explanation:

No of desks along  length of the rectangle = 7 as it is 7 rows wide.

No of desks along  breadth of the rectangle = 7 as it is 5 rows long.

Total number of students is product of these two numbers.

So number of students = 35.

But three desks are empty.

Total students = 35- 3

                         = 32.

If the area of a park is exactly halfway between 2.4 and 2.5 acres what is the area of the park
Paul [167]
Get the distance between two acres.

2.5 - 2.4 = 0.1

Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.

Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.

2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres

OR

Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.

2.5 + 2.4 = 2.9 / 2 = 2.45 acres
