Answer:

40 cotton bags  and  120 peanuts bags

Step-by-step explanation:

Let cotton candy bags be x and peanuts bag be y

x + y = 160 ........from Theory 1

4x + 2.5y = $460 ...............from Theory 2

Making x the subject:

x + y = 160

x = 160 - y ...........equation 1

4x + 2.5y = $460

4x = $460 -  2.5y

x = ($460 -  2.5y)/4 ..............equation 2

Solving both equations simultaneously:

160 - y = ($460 -  2.5y)/4

4(160 - y) = $460 -  2.5y

640 - 460 = -  2.5y + 4y

180 = 1.5y

y = 180/1.5

y = 120

Therefore there are 120 peanuts bags.

Then the number of cotton bags are: x + y = 160

                                                            : x + 120 = 160

                                                            : x = 40 cotton bags

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that   [tex]\frac{1}{x^{n}} = x^{-n}[/tex]

In this case, [tex]\frac{1}{y^{24}} = y^{-24}[/tex]

Set that equal to [tex](y^{b})^{4}[/tex]:

[tex](y^{b})^{4} = y^{-24}[/tex]

Apply the exponent rule that [tex](x^{m})^{n} = x^{mn}[/tex] so now you get:

[tex]y^{4b} = y^{-24}[/tex]

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6

Answer:

y = 3x-3

Step-by-step explanation:

i found the slope by comparing the points (1,0) and (0,-3)

the difference of the y-values over the difference of the x-values equals 3

[tex]\frac{(-3-0)}{(0-1)}[/tex] equals -3/-1 or 3

the y-intercept, as seen in graph, is -3

therefore, y = 3x-3

Answer:

10

Step-by-step explanation:

Here it's given that the area of the shaded region is 48 u² and we need to find out the value of x .

The given figure is made up of two rectangles where the smaller one is inscribed into the bigger one .

So that ,

[tex]\longrightarrow[/tex] ar(bigger) - ar(smaller) = 48

[tex]\longrightarrow[/tex] [ (x+3) (x-4)] - 3(x) = 48

[tex]\longrightarrow[/tex] [ x² - 4x +3x -12 - 3x ] = 48

[tex]\longrightarrow[/tex] x² -4x -12 -48 = 0

[tex]\longrightarrow[/tex] x² - 4x - 60 = 0

[tex]\longrightarrow[/tex] x² - 10x + 4x - 60 = 0

[tex]\longrightarrow[/tex] x( x -10) +4(x -10) = 0

[tex]\longrightarrow[/tex] (x +4)(x-10) = 0

[tex]\longrightarrow[/tex] x = -4,10

Answer:

-10

Step-by-step explanation:

Let x = number of postcards sold (as this is the independent variable)

Let y = profit (as this is the dependent variable)

We need to find the equation of the straight line that passes through the two points.

Find the gradient using the formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where [tex]m[/tex] is the slope and [tex](x_1, y_1)[/tex]  and [tex](x_2, y_2)[/tex] are the two points

Let [tex](x_1, y_1)[/tex] = (4, 2)  and [tex](x_2, y_2)[/tex]  = (10, 20)

Therefore, [tex]m=\frac{20-2}{10-4}=\frac{18}{6} =3[/tex]

Now use the equation of line formula:  [tex]y-y_1=m(x-x_1)[/tex]

y - 2 = 3(x - 4)

y - 2 = 3x - 12

     y = 3x - 10

If Max doesn't sell any postcards, then x = 0.

Substituting x = 0 into the equation of the line:  y = (3 x 0) - 10 = -10

Therefore, Max's profit prior to selling any postcards is -10 (so he is at a net loss of 10 before selling any postcards).

Answer:

14 million dollars

Step-by-step explanation:

We notice that there's a pattern on the graph. The company has a loss of 2 million then it gains 4 million and so on. Given this rule, we notice that in 2007 that the company gained 4 million that time and was at 16 million. So, in 2008, the company should lose 2 million, thus giving a total of 14 million dollars.

when simplifying and expression like that you have to do something called “wording it out”so in this case you can tell that you are going to have to times 2 by whatever p+3 equals. So we add 2 to both the numbers as a exponets since it(2) is being going to be used to multiply, multiple numbers.

We got

[tex] \frac{f(x + h) - f(x)}{h} [/tex]

The function here is

9x^2 so we got now

[tex] \frac{9(x + h) {}^{2} - 9 {x}^{2} }{h} [/tex]

[tex] \frac{9( {x}^{2} + 2hx + {h}^{2} - 9 {x}^{2} }{h} [/tex]

[tex] \frac{9 {x}^{2} + 18hx + 9 {h}^{2} - 9 {x}^{2} }{h} [/tex]

Cancel out terms.

[tex] \frac{18hx + 9h {}^{2} }{h} [/tex]

If we direct subsitue we get

[tex] \frac{0}{0} [/tex]

which is intermidate form in calculus so now, let try to find another way to evaluate this, we can factor out 9h

[tex] \frac{9h(2x + h}{h} [/tex]

Cancel out h

[tex]9(2x + h)[/tex]

Subsitue 0 for h.

[tex]9(2x + 0)[/tex]

[tex]9(2x)[/tex]

[tex]18x[/tex]

The answer here is 18x.

Step-by-step explanation:

so  for every 3 Reid washes there are 4 Elsie washes

the ratio of washing is 3:4

lets add 3 and 4 up

3 + 4 = 7

now lets divide the total number of washes by the added ratio

84/ 7

=12

now we know that 1 part is 12

to find Elsie's part we need to x 12 by how many parts she has got

she washed 4 times

3x=76-40

3x=36

x=12

a=40-12

a=28

Answer:

the answer is 9.5 cm

Step-by-step explanation:

so CD=CE=BD=AE\

CD=4.6cm

CE=11.5cm

BD=8.3cm so AE=BD times ce=3.8 times 11.5=4.6=9.5cm YOUR WELCOME

The measure of AE is 9.5 cm and the length of AB is 6.3 cm.

Given that, ABC and EDC are straight lines EA is a parallel to DB. EC= 11.5 cm, DC =4.6 cm DB =3.8 cm.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

From the figure,

∠CAE=∠CEA (Corresponding angles of parallel lines are congruent)

∠CBD=∠CDB (Corresponding angles of parallel lines are congruent)

From AA similarity ΔCAE≈CDB

Now, EC/DC = AE/DB

⇒11.5/4.6 =AE/3.8

⇒ AE = (11.5 × 3.8)/4.6

⇒ AE = 9.5 cm

⇒11.5/4.6 =10.5/BC

⇒ BC = (4.6 × 10.5)/11.5

⇒ BC = 4.2 cm

Then, AB=10.5-4.2 = 6.3 cm

Therefore, the measure of AE is 9.5 cm and the length of AB is 6.3 cm.
