400lbs/340ft^2

Factor out largest common factor.  LCF is the product of shared primes of the numbers prime factorization.

400=2*2*2*2*5*5,  340=2*2*5*17

So the product of the shared primes is 2*2*5=20, so divide the numerator and denominator by 40.

(400/20)lbs/(340/20)ft^2

20lbs/17ft^2  or if you prefer

(20/17)lbs/ft^2

(1 3/17)lbs/ft^2 or approximately

1.18 lbs/ft^2

An exponential model shows the growth of a towns population in years. Identify the parts:
Semmy [17]

9514 1404 393

Answer:

  • 2% growth per year
  • 25,000 to start
  • 12 years
  • 31,706 currently

Step-by-step explanation:

The base of the exponent is (1 +0.02). The value 0.02 = 2% is the growth rate. It is positive, signifying a 2% rate of growth per year. (Negative values would mean decay.)

The number 25000 that multiplies the exponential term is the value of the expression when the exponent is zero. It represents the starting population.

The exponent is said to be in years, so the time is 12 years.

The current population is the value of the expression:

  25,000(1.02^12) ≈ 31,706 . . . . current population

Solve for g<br>-6g + 3g + 12 &gt; -18<br>A.g&lt;2<br>B.g&gt; 2<br>C.g&lt;10<br>D.g&gt; 10​
Minchanka [31]

Answer:

g < 10

Step-by-step explanation:

-6g + 3g + 12 > -18

Combine like terms

-3g +12 > -18

Subtract 12 from each side

-3g+12-12 > -18-12

-3g > -30

Divide each side by -3, remembering to flip the inequality

-3g/-3 < -30/-3

g < 10
