How many pounds of candy that sells for $0.82 per lb must be mixed with candy that sells for $1.36 per lb to obtain 9 lb of a

Lady_Fox [76]

7.5 pounds of the $0.82 per lb candy must be used in the mixture.

<h3>How many pounds of each candy should we use?</h3>

First, let's define the variables:

x = pounds of the $0.82 candy used.
y = pounds of the $1.36 candy used.

We want to make 9 lb of mixture, then:

x + y = 9.

And the price of these 9 pounds must be $0.91, then we can write:

x*$0.82 + y*$1.36 = 9*$0.91 = $8.19

Then we have a system of equations:

x + y = 9.

x*$0.82 + y*$1.36 = $8.19

We can isolate y on the first equation so we get:

y = 9 - x

Now we can replace that on the other equation:

x*$0.82 + (9 - x)*$1.36 = $8.19

And now we can solve this for x.

x*($0.82 - $1.36) = $8.19 - 9*$1.36

-x*$0.54 = -$4.05

x = (4.05/0.54) = 7.5

So 7.5 pounds of the $0.82 per lb candy must be used in the mixture.

Five-sixth is equivolent to

victus00 [196]

First it's not "equivolent" but "equivalent".

Second it's not "five-sixth" but "five sixths".

Third five sixths is just five sixths you cannot simplify it further.

Hope this helps mathematically and grammatically.

Answer:

f ( x ) = - 2x^2 + 3x + 1

Step-by-step explanation:

If f ( x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞ < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

Solution; f ( x ) = - 2x^2 + 3x + 1, where the degree is 2, the LCM ⇒ - 2

Suppose that Jamal can choose to get home from work by taxi or bus. When he chooses to get home by taxi, he arrives home after 7

qwelly [4]

Answer:

0.55

Step-by-step explanation:

There are four things you need to keep in mind,and the question is too easy to solve , so following are those four things

1)Jamal travelling by Taxi before 7 PM

It is given that Jamal uses the bus for 70 percent of the time so he will use the taxi for (100-70)%=30% of the time.

and also it is given that he arrives home by taxi after 7 PM , 15% of the time so he will arrive home by taxi before 7 PM ,(100-15)=85% of the time,

so by multiplication law of probability , the probability that Jamal will arrive by taxi before 7 PM =0.30*0.85=.255

2)Jamal travelling by Taxi after 7 PM

Similarly by considering the above situations as described in first part,

the probability that Jamal will arrive by taxi after 7 PM=0.30*0.15=.045

3) Jamal travelling by Bus before 7 PM

Now considering the case of the bus, it is given that Jamal arrives home after 7 PM 8 percent of the time. so for before 7 PM it will be 100-8= 92%

Similarly the probability that Jamal will arrive by bus before 7 PM=0.70*0.92=.644

4) Jamal travelling by Bus after 7 PM

Similarly on the basis of above explanation we can easily say that the probability that Jamal will arrive by bus after 7 PM=0.70*.08=.056

so, the probability that Jamal chose to get home from work by bus, given that he arrived home after 7 pm= $=\frac{Jamal travelling by bus after 7 PM}{(Jamal travelling by taxi after 7 PM +Jamal travelling by bus after 7 PM}$

$=\frac{0.056}{0.056+0.045}$

$=\frac{0.056}{0.101} \\=0.554$
