Ummm i dont even believe thats a reasonable question theres no 20 cent coins
3t/4=2p/5 solve for p
p=15t/8
p=1.875 tons of sand
11/3....this is rational because it is a fraction
sqrt 48.....irrrational because it cant be made into a fraction
6.25....rational
0.01045....if this terminates(ends), it is rational
sqrt 16/81....rational because it equals 4/9
sqrt 3/16....irrational
0.42...rational
16pi....irrational
13 By the factor theorem, if the function is divisible by x - 3 then f(3) = 0. So we have:-
2(3)^3 + k(3)^2 + 7(3) - 3 = 0
9k = 3 - 21 - 54 = -72
k = -72/9 = -8 answer
14. Similarly , f(-4) = 0 , so we have:-
(-4)^3 + 9(-4)^2 + k(-4) - 12 = 0
-64 + 144 - 4k - 12 = 0
4k = -64 + 144 - 12 = 68
k = 68/4
k = 17 answer
6 lots can be created
<em><u>Solution:</u></em>
Given that neighborhood development that is 4 acres is to be divided into 
acre lots
To find: number of lots created
From given information,
Total acres = 4
one lot = 
So number of lots created can be found by dividing the total acres by acre of 1 lot
<em><u>Thus the formula is:</u></em>
<em><u>Substituting the values we get,</u></em>
Thus 6 lots can be created
