First, you would need to create an equation for this problem.
3 \frac{1}{2} ÷ \frac{1}{4}

Next, you would flip the second fraction and change it to multiplication.
3  \frac{1}{2} × \frac{4}{1}

Now, you would change the first fraction into an improper fraction and cross simplify the equation. 
\frac{7}{2} × \frac{4}{1}
\frac{7}{1} × \frac{2}{1}

Finally, you would solve it. 
\frac{7}{1} × \frac{2}{1} = \frac{14}{1} = 14

3 \frac{1}{2} ÷ \frac{1}{4} = 14

I hope this helps!

The food bank has 1774.4 oz of chicken.If 12.6 oz is 2 servings,how many servings of chicken does this provide?
diamong [38]

Answer:

281 servings

Step-by-step explanation:

From the table attached,

We will apply the unitary method to solve this problem.

∵ 12.6 oz of chicken represents number of servings = 2

∴ 1 oz of chicken will represents number of servings = \frac{2}{12.6}

∴ 1774.4 oz of chicken will make the total servings = \frac{2}{12.6}\times 1774.4

                                                                                    = 281.65

                                                                                    ≈ 281 servings

Therefore, total number of servings provided = 281

<span> 4.1 </span>  <span> 6m3 - 16m2 + 15m - 40</span>  is not a perfect cube 

Trying to factor by pulling out :

<span> 4.2 </span>     Factoring: <span> 6m3 - 16m2 + 15m - 40</span> 

Thoughtfully split the expression at hand into groups, each group having two terms :

5X-50+2X+80-X=180..............
JulsSmile [24]

Hey there!

5x - 50 + 2x + 80 - x = 180

COMBINE the LIKE TERMS

= 6x + 30 = 180

SUBTRACT 30 to BOTH SIDES

6x + 30 - 30 = 180 - 30

CANCEL out: -30 - 30 because that gives you 0

KEEP: 180 - 30 because it helps solve for the x-value

6x = 180 - 30

180 - 30 = 150

NEW EQUATION: 6x = 150

DIVIDE 6 to BOTH SIDES

6x/6 P 150/6

CANCEL out: 150/6 because that gives you the result of the x-value

x = 150/6

SIMPLIFY IT!

x = 25

Therefore, your answer is: x = 25

Good luck on your assignment and enjoy your day!

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million u
EleoNora [17]

Answer:

when the survey was initially conducted the average sales of smartphones was 1.7 million units

Step-by-step explanation:

The average annual sales of smartphones is given by function

P(n)= 1.7 (b)^n

Exponential growth function is given by

f(x)= ab^x

Where a= initial value

b = growth factor , b= 1+r where 'r' is the growth rate

x is the time period

Now we compare f(x) with P(n)

the value of a= 1.7 that is the initial value.

So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
