Answer:
$2.85
Step-by-step explanation:
The price Ellen pays can be found using the proportion ...
price/(24 oz) = $1.90/(16 oz)
Multiplying by 24 oz, we get ...
price = $1.90(24/16) = $2.85
Ellen pays $2.85 for the beans.
X^2-12x+7=0 move constant to other side
x^2-12x=-7 add the square of half the linear coefficient to both sides...(12/2)^2=36
x^2-12x+36=29 now the left side is a perfect square...
(x-6)^2=29 so if
f(x)=(x-a)^2+b then
f(x)=(x-6)^2-29
So a=6
One rose is 50 cents, so 2 roses cost $1 ( 50 cents x 2).
2 roses per dollar x 20 dollars = 40 total roses sold.
When they sell $20 dollars they make $6, so that means they pay 20-6 = $14 dollars for the 40 roses.
$14 / 40 roses = 0.35 per rose.
She pays 35 cents per rose.
Answer: D
Step-by-step explanation:
The number generator is not fair, in most of the experiments, considerably less than 60 % of the selected marbles are green.
And if Sixty percent of the marbles in the jar are green. A number generator should simulates randomly by selecting atleast one of the 60% of green marbles from the jar
