Answer:
x = -0.907, 2.57
Step-by-step explanation:
Quadratic Formula: 
Since we are given <em>a</em> = 3, <em>b</em> = -5, and <em>c</em> = -7 from our quadratic, we simply use the Quadratic Formula:
Step 1: Plug in variables
Step 2: Solve
Step 3: Evaluate for decimals
You should get x = -0.906718 and 2.57338 as your answers.
Answer: The answer is 41.13 pounds (approx.).
Step-by-step explanation: Given that the average production of potatoes in 2012 was 0.946 pounds for every 0.000023 power acre harvested. We need to calculate the pounds of potatoes produced on average for each acre harvested.
For that, we need to divide the pounds of potatoes by number of acres harvested.
In 0.000023 acre harvested, ponds of potatoes = 0.946 ponds.
Therefore, in 1 acre harvested, pounds of potatoes is given by
Thus, the answer is 41.13 pounds (approx.).
D=dimes
n=niclkes
p=pennies
q=quarters
1 dollar (100 cents)
2 times as many nickles as dimes
n=2d
14 more pennies than quarters
p+14=q
and total is 1 dollar so
25q+10d+5n+p=100
ok so we must use logic
the max number of quarters in a dolar is 4
but there are pennies so max is 3
so q=1,2, or 3
therefor p=15,16 or, 17
also, the rest of te coins are only multipules of 5 so the sum amount of pennies and quartes must add to a multiplule of 5
if q=1 and p=15, total is 40 cents
if q=2 and p=16, total is 66 cents
if q=3 and p=17, total is 92 cents
only 40 cents is a multiplule of 10
1 quarter and 15 pennies
now we are having
40 cents is pennies and quartesrs
therfor 100-40=60 cents is nickles and dimes
60=5n+10d
n=2d
sub
60=5(2d)+10d
60=10d+10d
60=20d
divide both sides by 20
3=d
sub
n=2d
n=2(3)
n=6
6 nickles
3 dimes
answer is
1 quarter
3 dimes
6 nickles
15 pennies
