Answer:
A=2
Step-by-step explanation:
divide the numbers
A/9 =14/63
A/9 =2/9
Multiply same terms by same value to eliminate fraction denominators
A/9 =2/9
9. A/9 = A.2/9
Simplify
Cancel multiplied terms that are in the denominator
Multiply the numbers
= 2

Answer:
16.3 years
Step-by-step explanation:
1 ha = 10,000 m^2
The total capacity of the landfill is:

If waste is compacted to twice its delivered density, its volume is half of the delivered volume. Assuming that a year has 52 weeks, the volume of compacted solid waste dumped per year is:

The expected life of the landfill is given by its capacity divided by the yearly volume:

The landfill has an expected life of 16.3 years.
Answer:
x=-6
Step-by-step explanation:
Follow along:
1. Distribute the -3 to those within the parenthesis.
-3x-6=12
2. Move the whole numbers to one sides, isolate the variable.
-3x=18
3. Divide both sides by -3
x=-6
Answer:
the interest earned= 93.401
and the future value of an annuity= 493.401
Step-by-step explanation:
Given Data:
Interest rate= 7%
time,t = 3 years
weekly payment, P= 400
At the end of 3 years, final investment A= ?
n= 52 as it is weekly
As per the interest formula
A= P(1+r/n)^nt
Putting value in above equation
= 
= 493.401
Interest earned = A-P
= 493.401-400
= 93.401 !
