so, value of x = 68°
Area of Consuela's rectangular living room = 360 square feet
Let us assume the the length of the living room = x
Then
width of the living room = (5/8) * x
= (5x/8)
Then
Area of the rectangle = Length * Width
360 = x * (5x/8)
360 = 5x^2/8
2880 = 5x^2
x^2 = 2880/5
x^2 = 576
x^2 = (24)^2 inches
x = 24
Then
The length of the rectangle is = 24 inches
And
The Width of the rectangle is = 24 * (5/8) inches
= 3 * 5 inches
= 15 inches
The number of remaining problems is:
30-20 = 10 problems.
The amount of time remaining is:
40-25 = 15minutes
For the first 20 problems the time per problem is:
t1 = 25/20 = 5/4 minutes
For the remaining problems the time per problem is:
t2 = 15/10 = 3/2 minutes
Answer:
you will be able to spend about 3/2 minutes on each remaining problem
