Answer:
2 days
Step-by-step explanation:
Understanding :
- Number of men is inversely proportional to the number of days taken to complete a job
- 6 men take 5 days to complete 1
- Now the number of men is 15
Solving :
- Rate of change of men ∝ 1/Rate of change of days
- 15/6 ∝ 1/(d/5)
- 2.5 = 5/d
- d = 2 days
The answer should be 19.25
Answer:
Lines that are parallel have the same gradient.
Since the line is y=-5/6x-4,the gradient of the line parallel to this line is also -5/6.
So the equation of the line parallel to y=-5/6x-4 is y-(-2)=-5/6(x-(-6))--->y=-5/6x-7.
Lines that are perpendicular fulfill the requirement: gradient 1×gradient 2=-1 . Then once you find the gradient of the line, you can find the equation of the line.
<u><em>Its 41....VERY EASY</em></u>
Let me show you:
4*4= 16 because of the exponent (2)
4 times 4 =16
Then add by 25..
Which gives u 41..

<u>Formula Evaluation</u>
Formulas are expressions where a sequence of letters, numbers or symbols have a determined meaning in given system.
Formulas are usually expressed as mathematical operations that connect one or more variables.
The perimeter of a triangle is the sum of the lengths of its sides. Being a,b, and c their sides, then the perimeter has the formula

We are given the values of



Thus the perimeter is
