Answer:

a=\frac{8}{9}

Step-by-step explanation:

3^x-3x^{x-2} =a3^x

Divide both sides by 3^x:

3^{x-x}-3^{x-x-2}=a

Simplify:

3^0-3^{-2}=a\\a=1-\frac{1}{9} \\a=\frac{8}{9}

A similar scale model of a building is 12 in tall and 9 in wide. If the actual building is 100 ft tall, how wide is the building
Dmitry [639]
You just put the scale of one building on one side and the scale of the similar building on other side, with width and length written in same place (denominator or numerator). With x for the part that you dont know

Length of one building / width of one building = length of other building / width of other building

12 / 9 = 100 / x

Solve for x, by cross-multiplying

12 * x = 100 * 9
12x = 900
X = 900/12
X = 75 ft

Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%

2. Probability of the mail being delivered before 2 pm for 2 consecutive days is

WINSTONCH [101]

For this, you have to calculate the Unit value,

Unit value of 1rst one,  4.99/6 = 0.83

Unit value of 2nd one, 7.99/10 = 0.79

As, 2nd one is cheaper, so it is better :))
