Anna35 [415]

Answer:

There where 10 more Small boxes sold than Large boxes.

Step-by-step explanation:

This is a typical question that can be solved by obtaining a system of two linear equations and solving for each variable.

In principle Linear Equations are algebraic expressions denoting a relationship between a Dependent variable $y$ and an Independent variable $x$ . In a system of Two Linear equations we have two equations of the same variable sets (thus Two Independent variables) so in this case both $y$ and $x$ will be variable terms.

Now with respect to the question and the given information, here our two Variable terms will be the small and the large boxes.

Given Information:

Small Boxes (lets call them $s$ ) cost $1 per box

Large Boxes (lets call them $l$ ) cost $4 per box
Total Number of Boxes sold is 30
Total Profit from sold Boxes is $60

Thus from the above we can obtain one equation denoting the Total Number of Boxes sold and one equation denoting the Total Profit from sold boxes, respectively, as follow:

$s+l=30$ Eqn(1): Total Number of Boxes

$1s+4l=60$ Eqn(2): Total Profit from sold boxes

Now we have a system of two linear equations which we can solve and find the number of small and large boxes, $s$ and $l$ respectively.

From Eqn(1) we see that

$s=30-l$ Eqn(3).

Plugging Eqn(3) in Eqn(2) we can solve for $l$ as:

$1(30-l)+4l=60$

$30-l+4l=60$ Factored out bracket

$3l=60-30$ Gather similar terms on each side and simplify

$3l=30$

$l=\frac{30}{3}$

$l=10$

Plugging in the value for $l=10$ in Eqn(3) we have

$s=30-10\\s=20$

So we know that they were 10 Large Boxes and 20 Small Boxes sold, thus to answer our question, there where 10 more Small boxes sold than Large boxes.

I’m struggling on both of them can you give both answers

4.16 hours and 4 cups

Step-by-step explanation:

10. To find the % of something simply turn 5/6 in to a decimal (.83) then times it by the number you want .83 * 60 = 50 so its about 50 min each class, just times it by 5 =250 and lastly divide it by 60 for hours 4.16

11. Simply times it by 6, 2/3*6= 4 cups

Classify each number by indicating in which set or sets it belongs 8 and 0.25

Daniel [21]

we are given with two numbers: 8 and 0.25. In this case, we are asked in the problem to determine the set in which the numbers belong to. 8 belongs to whole numbers and integers, as well as natural numbers. 0.25 belongs to decimal numbers and whole numbers

Shenelle has 100100100 meters of fencing to build a rectangular garden. The garden's area (in square meters) as a function of th

Step2247 [10]

Answer:

<h2>25metres</h2>

Step-by-step explanation:

Given the area of the garden in terms of the width modeled by the equation A(x) = -(x-25)²+625 where x is the width of the garden. The side with that will produce the maximum garden area is occurs at when d[A(x)]/dx = 0

Given A(x) = -(x-25)²+625

d[A(x)]/dx =-2(x-25) + 0

Since d[A(x)]/dx = 0

-2(x-25) = 0

open the parenthesis

-2x+50 = 0

-2x = 0-50

-2x = -50

Divide both sides by -2;

-2x/-2 = -50/-2

x = 25metres

Therefore the width of the garden that will produce the maximum garden area is 5metres.
