2. The food pantry of Ellicottville received a huge donation of fruit snacks during the month of December. The table below shows

ANSWER

$238\text{ fruit snacks per after-school program}$

EXPLANATION

We have that there are 12 after school programmes and each one got an equal number of packages.

To find the number of fruit snacks that each received, we have to find the total number of fruit snacks.

The total number of fruit snacks can be found by multiplying the number of boxes of each flavor by the number of packages in each box, then adding them up:

$\begin{gathered} \text{TOTAL}=(48\cdot4)+(78\cdot9)+(90\cdot11)+(108\cdot9) \\ \text{TOTAL}=192+702+990+972 \\ \text{TOTAL}=2856\text{ fruit snacks} \end{gathered}$

Now, to find the number of fruit snacks that each received, divide by 12:

$\begin{gathered} \frac{2856}{12} \\ 238\text{ fruit snacks per after-school program} \end{gathered}$

What are the exact solutions of x2 = 5x + 2? (1 point)

bazaltina [42]

Answer:

A. x equals 5 plus or minus the square root of thirty-three all over 2

Step-by-step explanation:

Let's move all the terms to one side:

$x^2=5x+2$

$x^2-5x-2=0$

Now, we want to use the quadratic formula, which states that for a quadratic equation of the form $ax^2+bx+c=0$ , the roots can be found with the equation: $x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ or $x=\frac{-b-\sqrt{b^2-4ac} }{2a}$ .

Here, a = 1, b = -5, and c = -2, so plug these in:

$x=\frac{-(-5)+\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5+\sqrt{25+8} }{2}=\frac{5+\sqrt{33} }{2}$

$x=\frac{-(-5)-\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5-\sqrt{25+8} }{2}=\frac{5-\sqrt{33} }{2}$

Thus, the answer is A.

Hope this helps!

If you draw three cards from a regular deck of 52 cards, keeping each card out of the deck after you draw it, what are the chanc

bulgar [2K]

There are four 7's in a standard card. Chance of getting a 7 first is 4/52 = 1/13
There are four queens in a standard card. Chance of getting a queen in the second drawing is 4/51 and chance of getting a queen in the third drawing is 3/50.

Therefore, chance of drawing a seven and two queens is 1/13 x 4/51 x 3/50 = 2/5525

An electron has an atomic mass of 5.4 x 10-4. If a carbon atom has 6 electrons, what is the combined atomic mass of the electron

Gwar [14]

6*5.4*10^(-4)
=32.4*10^(-4)
move the decimal point, in scientific notation you only have a single digit with comma
=3.2*10^(-3)

so option A

to know if you have to increase or decrease the exponent you can write the intermediary steps out:
32.4*10^(-4)=32.4/10^4=(3.24*10)/(10*10^3)
reduce the fraction and you have the above solution

Olivia signed up for a streaming music service where there's a fixed cost for monthly membership and a cost per song downloaded.

Nuetrik [128]

Answer:

(A)If x represents the number of songs she downloads then it is a variable because of the AMOUNT of songs she downloads.

Step-by-step explanation:

For example if we had f(x)=2 the equation would be c=4.99+.75(2)

.75*2=1.50+4.99=

(6.49 = c) cost per month if she downloads 2 songs
