Answer:
<u>25 hours</u>
Step-by-step explanation:
It takes 5 men 45 hours to build a wall.
So, if no. of men increases by 1.8 [∴ 5 x 1.8 = 9],
then time taken reduces by that same amount.
=> 45 hours / 1.8
=> 45 / (9/5)
=> 45 x 5 / 9
=> 5 x 5
=> <u>25 hours</u>
43.9 + n = 49.65
43.9-43.9 + n = 49.65 -43.9
n = 5.75
Answer:
Length = 12 feet
Perimeter = 28 feet
Area = 24ft²
Step-by-step explanation:
You didn't ask a question so I don't know what the answer you want is so I assumed it was related to one of the answers shown above.
To calculate the length, you simply do 6*2
which is equal to 12.
The length is 12 feet.
However, if you want to find the perimeter:
12 + 12 + 2+ 2 = 28ft
If you wanted to find the area:
12*2 = 24ft²
I hope this helps!
Answer:
A and C
Step-by-step explanation:
X is the number of weeks, so it is a possitive number. As the debt reduces while weeks advance, then there should be a substraction between total debt and payments, therefore options C and D are not possible
Debt would start as a negative number in -825, and would reduce up to zero. You know that you he can pay more but not less than 85 per week, so suppouse he pays more than 85, let's say $100, then the debt should be 100-825=-725 that is larger than 85-825=-740. So The option A represent the amount of debt
2 question
After 3 weeks Martin has payed at least: 85*3=255. So debt is not more tha 825-255=570, so scenario A is possible
With the sema logic, after 4 wekks debt is not larger than: 825-4*85=485, so option B is possible
After 5 weeks: debt is not larger than= 825-5*85=400. So scenario C is NOT possible
After 6 weeks debt is not larger than 825-6*85=315, so scenario D is possible
