Answer:18h^2+85h-18
Step-by-step explanation:
The formula to find the volume of a pyramid is: V=lwh/3 therefore:
V = lwh/3
38 = 6(6)(h)/3
114 = 36(h)
h = 3.17 (2 dec. places)
The height of the square pyramid is 3.17cm.
The tax rate needed to balance the budget will be ...
tax rate = (budget amount)/(tax base)
In millions*, this is
tax rate = 1.1/90 = 0.0122... ≈ 12.2/1000 = 12.2‰
In terms of mils, the tax rate is 12.2.
_____
* As long as numerator and denominator are both expressed in millions, the factor of 1 million cancels from numerator and denominator and the fraction is the same value it would be if we put in all those zeros.
Here is how to do the problem
x=construction worker salary
y=fast food worker salary
x+y=65
x+11=3y
Substitution.
x=65-y
65-y+11=3y
4y=76
y=19
x+19=65
x=46
const. worker salary = 46k
fast food = 19k
Answer:
To solve square root equations, isolate the radical on one side of the equation. Then, raise both sides of the equation to the same power.
