Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
use w=12 to solve for l
l=2(12)
l=24
Answer: the number of multiple choice questions in the test is 12.
the number of short response questions in the test is 8.
Step-by-step explanation:
Let x represent the number of multiple choice questions in the test.
Let y represent the number of short response questions in the test.
The total number of questions in the test is 20. It means that
x + y = 20
The multiple choice questions are worth 3 points each and the short response question are worth 8 points each. The total number of points is 100. It means that
3x + 8y = 100 - - - - - - - - - - 1
Substituting x = 20 - y into equation 1, it becomes
3(20 - y) + 8y = 100
60 - 3y + 8y = 100
- 3y + 8y = 100 - 60
5y = 40
y = 40/5 = 8
x = 20 - y = 20 - 8
x = 12
36 miles is equal to 1 hour ( 60 minutes)
Do a ratio,,
36 : 60
87 : ?
To work out the unknown ratio, do 60/ 36 and then multiply by 87 to get
145 minutes. To convert that into hours you would get 2 hours and 25 minutes
Add that on to 07 00
He would get there at 09 25
Hope this helps! Any questions let me know :)
the line go through 2 points ( -4 ; -5 ) and ( 6 ; 4 )
