Answer: 6 cups of lemonade for Aaliyah

Step-by-step explanation:

If Donald used 1 1/2 cups of lemonade-

And Aaliyah uses 4 times that amount-

Aaliyah does 4 times that amount you will do 1 1/2 *4 which is 1*4=4 and 1/2*4=2 so Aaliyah uses 6 cups of lemonade.

1 1/2 * 4 = 6

The value of box/ square is 5, value of circle is 3 and the value of star is 6.

Let box/ square be denoted by x

let the circles be denoted by y

let the stars be denoted by z

now, let us make three linear equation based on the diagram provided

1. x + x = 10

2. y + z= 9

3. y+ x = 8

solving equation 1

x + x = 10

2x = 10

x = 5

Putting the value of x in equation 3

y + x=8

y + 5 = 8

y = 3

Putting the value of y in equation 2

y + z = 9

3 + z= 9

z = 6

Hence , The value of box/ square is 5, value of circle is 3 and the value of star is 6.

A linear equation is one in which the variable's maximum power is always 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. In this equation, x is a variable, A is a coefficient, and B is constant. A linear equation in two variables has the conventional form Ax + By = C.

A linear equation is an equation with the maximum degree of one. This means that in a linear equation, no variable has an exponent greater than 1. A linear equation's graph is always a straight line.

The area of polygon A would be a fraction 1/25 of the size of polygon B.

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object

The formula of the scale factor is shown as;

Area of Polygon B = (scale factor)²×(Area of Polygon A).

Using a scale factor of 5, we get

(Area of Polygon B)  = (5)²× (Area of Polygon A)

(Area of Polygon B) = (25) × (Area of Polygon A)

Area of Polygon A = (1/25) × Area of Polygon B

Answer:

y = x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3 ) and (x₂, y₂ ) = (2, 4 )

m = [tex]\frac{4-3}{2-1}[/tex] = [tex]\frac{1}{1}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 3 )

3 = 1 + c ⇒ c = 3 - 1 = 2

y = x + 2 ← equation of line

The equation that we would use to find the value of x based on the area of a rectangle is:

C. (16 + 2x)(12 + 2x) = 396

To find the area of a rectangle, find the product of its length and its width. Thus, the area of a rectangle is: (length)(width) = area.

Given the following:

Area of both the walkway and the garden = 396 square meters

Length = x + 16 + x = 16 + 2x

Width = x + 12 + x = 12 + 2x

Using the area formula for a rectangle, we would have:

(16 + 2x)(12 + 2x) = 396.

What is the meaning of APR of 16.99%?

The APR means an annual percentage rate, which means that the 16.99% is annual interest rate compounded monthly, hence, it needs to be divided by 12 in order to determine the equivalent monthly interest rate.

monthly interest rate=16.99%/12

monthly interest rate=0.0141583333333333

The monthly interest charged on the balance of $1,567.32 is computed thus:

Range: [tex]\:f\left(x\right)\ge \:-\frac{68}{11}[/tex]

Interval notation [tex][-\frac{68}{11},\:\infty \:)[/tex]

Step-by-step explanation:

I got a little confused with the x - 1/2x^2 term and I am taking to to be:

[tex]x\:-\frac{1}{2}x^2[/tex]  . If this is incorrect please mention the correct term in your comment and I will edit this post. Or you can re-post the question

We have
[tex]f\left(x\right)=6x^2+x\:-\frac{1}{2}x^2+\:x\:-\:6[/tex]

Simplify by grouping like terms:
[tex]=-\frac{1}{2}x^2+6x^2+x+x-6[/tex]

[tex]= \frac{1}{2}x^2+6x^2+2x-6[/tex]

Add similar elements
[tex]-\frac{1}{2}x^2+6x^2[/tex][tex]= -\frac{1x^2}{2}+\frac{12x^2}{2} = \frac{11x^2}{2}[/tex]

So the original function expression becomes
[tex]y=\frac{11}{2}x^2+2x-6[/tex]

This is the equation of a parabola which in standard form is [tex]ax^2 + bx + c[/tex]

Here
[tex]a=\dfrac{11}{2},\:b=2,\:c=-6[/tex]

We can compute the vertex of this parabola using the fact that the x, y coordinates of the vertex are given by
[tex]x_v =-\dfrac{b}{2a}[/tex]

Plugging in values for b and a give us
[tex]x_v =-\dfrac{b}{2a} = -\dfrac{2}{2\left(\dfrac{11}{2}\right)} =-\dfrac{2}{11}[/tex]

Plugging in this value of [tex]x_v[/tex] into the parabola equation will give the value for [tex]y_v[/tex] which is the function value at the vertex

Plug in [tex]x_v = -\frac{2}{11}[/tex] t find the [tex]y_v[/tex] value:
[tex]y_v=\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2}+2\left(-\dfrac{2}{11}\right)-6[/tex]

Simplify
[tex]\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2} =\dfrac{2}{11}[/tex]

[tex]2\left(-\dfrac{2}{11}\right) = -\dfrac{4}{11}[/tex]

Combining the terms we get
[tex]y_v =[/tex] [tex]\dfrac{2}{11}-\dfrac{4}{11}-6[/tex] [tex]= -\dfrac{68}{11}[/tex]

[tex]\textsf{Therefore the parabola vertex is at }[/tex] [tex]\left(-\dfrac{2}{11},\:-\dfrac{68}{11}\right)[/tex]
For a parabola of the form [tex]ax^2 + bx + c[/tex] with vertex [tex]\left(x_v,\:y_v\right)[/tex]

[tex]\circ \;\mathrm{If}\:a < 0\:\mathrm{the\:range\:is}\:f\left(x\right)\le \:y_v[/tex]
[tex]\circ \;\mathrm{If}\:a > 0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v[/tex]

Here [tex]a=\frac{11}{2}[/tex] so the range is [tex]f\left(x\right)\ge \:-\dfrac{68}{11}[/tex]

Answer range of f(x) is
[tex]f\left(x\right)\ge \:-\dfrac{68}{11}[/tex]

In interval notation it is [tex][-\frac{68}{11},\:\infty \:)[/tex]

The percent makeup on each bag of popcorn is 25%.

When a fraction of a whole is expressed as a number between 0 and 100, it is called a percentage. The percentages 100%, 50%, 0% indicate all of some quantity, half of the quantity, and none of the quantity respectively.

Popcorn is being sold by a neighborhood nonprofit to support hurricane relief.

The organization paid $4 for each bag of popcorn.

The organization sold each bag of popcorn for $5.

The markup or gain from selling the popcorn is:

$5 - $4 = $1

Therefore, the percent makeup on each bag of popcorn will be:

= ( the gain / the amount organization paid for each bag ) × 100

= ( 1 / 4) × 100

= 0.25 × 100

= 25 %

Hence, the percent makeup on every bag of popcorn is 25%.
