Answer:

Number of cupcakes = 2

Number of cookies = 5

Step-by-step explanation:

Let [tex]x[/tex] denotes the number of cupcakes and [tex]y[/tex] denotes the number of cookies.

Abigail bought $11.25 worth of cupcakes and cookies such that each cupcake costs $3.75 and each cookie costs $0.75.

[tex]3.75x+0.75y=11.25[/tex]

At [tex]x=0;[/tex] [tex]0.75y=11.25[/tex]

[tex]y=\frac{11.25}{0.75} =15[/tex]

At [tex]y=0;3.75x=11.25[/tex]

[tex]x=\frac{11.25}{3.75}=3[/tex]

So, plot the points [tex](0,15)\,,\,(3,0)[/tex]

Also,

Abigail bought a total of 7 cupcakes and cookies altogether.

[tex]x+y=7[/tex]

At [tex]x=0;0+y=7[/tex]

[tex]y=7[/tex]

At [tex]y=0;x+0=7[/tex]

[tex]x=7[/tex]

So, plot points [tex](7,0)\,,\,(0,7)[/tex]

From the graph, solution is [tex](2,5)[/tex]

Number of cupcakes = 2

Number of cookies = 5

Answer:

200.6 degrees Celsius

We have the given number, 176.8 degrees Celsius, and we add or increase it by 23.8 degrees.

176.8 + 23.8 = 200.6

Our final answer is 200.6 degrees Celsius.

~Hope this helps~

Answer:

200.6'C or 461.2'F

Step-by-step explanation:

176.8'C

+ 23.8'C

--------------

200.6'C

To make 'F, we must add 30, then multiply by 2.

Answer:

$7,719.33

Step-by-step explanation:

$24,500 x 0.06 = $1,470

($24,500 + $1,470) x 0.06 = $1,558.20

($24,500 + $1,558.20) x 0.06 = $1,563.49

($24,500 + $1,563.49) x 0.06 = $1,563.81

($24,500 + $1,563.81) x 0.06 = $1,563.83

$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33

Answer: y = 3

Step-by-step explanation:  

So, we must find an equation of a line that passes through these two points such that we find the slope first as,  

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that  

y - y1 = m(x - x1). Next,  

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is

Answer:

D - 33

Step-by-step explanation:

From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.

Answer:

-10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-7)/(0-(-1))

m=-10/(0+1)

m=-10/1

m=-10

Answer:

The slope is -10.

Step-by-step explanation:

Goal

Given

Step 1

[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

From the given coordinate points, substitute the values in the formula.

[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]

Therefore, the value of m or slope is -10.

Step-by-step explanation:

Answer:

All exterior angles will add up to 360 degrees, regardless of the number of sides.

For the sum of the interior angles, use this formula:

The sum of the interior angles = (N x 180) - 360

Where N = the number of sides

So, (40 x 180) - 360 = 6840 degrees

The measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.

Important information:

Interior angle of a regular polygon is [tex]\dfrac{(n-2)\times 180^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each interior angle is:

[tex]\dfrac{(40-2)\times 180^\circ}{40}=38\times 4.5^\circ[/tex]

[tex]\dfrac{(40-2)\times 180^\circ}{40}=171^\circ[/tex]

Exterior angle of a regular polygon is [tex]\dfrac{360^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each exterior angle is:

[tex]\dfrac{360^\circ}{40}=9^\circ[/tex]

Therefore, the measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.
