Answer: the answer is d :)

The equation to represent the total cost of printing the calendars is y=500+2.50x.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

1) Given that, the cost of printing is $500, plus $2.50 per calendar.

Let the number of calendars be x and let the total cost be y.

So, the equation is y=500+2.50x

2) Each calendar will sell for $5.00 each.

The total income, y, for selling x calendars.

So, the total income is y=5.00x

Cameron estimates that the math class will sell 200 calendars.

So, the total cost = 5.00×200

= $1000

Now, y=500+2.50x

Substitute x=200 in y=500+2.50x, we get

y=500+2.50×200

y=1000

Hence, option D is the correct answer.

Therefore, the equation to represent the total cost of printing the calendars is y=500+2.50x.

Answer:

27 is your answer

Step-by-step explanation:

if 2;3 is your ratio and u have 18 peppermint gum then divide 18 by 2 and u get 9 then u multiply 9 by 3 and u get 27

The total number of spearmint gums will be 27

Given is that a container has peppermint gum and spearmint gum. There are 18 pieces of peppermint gum in the container and the ratio of peppermint gum to spearmint gum is 2 : 3.

Let the number of spearmint gum be {x}. So, we can write -

2/3 = 18/x

{x} = (18 x 3)/2

{x} = 27

Therefore, the total number of spearmint gums will be 27.

Answer:

Step-by-step explanation:

to find out the coresponding sides and angles draw 2 triangles that are the same and label them in same ORDER (I did counterclock wise) will help you see better the parts

  L.                  T

  Δ                  Δ

J.     K.         C.    O

JK≅ CO, JL≅CT, KL≅OT

∠J≅∠C, ∠L≅∠T, ∠K≅∠O

ΔTRI≅ΔAGN because corsponding parts are congruent

∠I≅∠N because are coresonding angles

Answer:

∠ Y = 34°

Step-by-step explanation:

Since XY = ZY then the triangle is isosceles and the base angles are congruent, thus

∠ X = ∠ Y , that is

6x - 23 = 4x + 9 ( subtract 4x from both sides )

2x - 23 = 9 ( add 23 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Thus

∠ Z = 4x + 9 = 4(16) + 9 = 64 + 9 = 73° = ∠ X

Hence

vertex angle Y = 180° - (73 + 73)° = 180° - 146° = 34°

Given:

Manuel wants to earn at least $44 trimming trees.

He charges $6 per hour and pays $4 in equipment fees.

To find:

The possible numbers of hours Manuel could trim trees.

Solution:

Let t be the numbers of hours Manuel could trim trees.

Earnings of Manuel in one hour = $6

Earnings of Manuel in t hour = $6t

He pays $4 in equipment fees. So, we will subtract this from the income.

[tex]\text{Total earnings}=6t-4[/tex]

Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.

[tex]6t-4\geq 44[/tex]

[tex]6t\geq 44+4[/tex]

[tex]6t\geq 48[/tex]

Divide both sides by 6.

[tex]t\geq \dfrac{48}{6}[/tex]

[tex]t\geq 8[/tex]

Therefore, the required number of hours must be greater than or equal to 8 hours.

Answer:

[tex]f[/tex] = 78

[tex]g[/tex] = 3.5

Step-by-step explanation:

First we need to find [tex]f[/tex].

We can use the equation [tex]72 + (f + 30) = 180[/tex] to solve for [tex]f[/tex].

We can then change that equation to [tex]72 + f + 30 = 180[/tex], since the Commutative Property of Addition says that you can have any addition in any order.

Now, we can solve the equation.

[tex]102 + f = 180\\(102 - 102) + f = 180 - 102\\f = 78[/tex]

Now that we solved [tex]f[/tex], we can now solve for [tex]g[/tex].

Since 25 equals [tex]8g -3[/tex], we can solve the equation [tex]8g - 3 = 25[/tex].

Here is how you solve it:

[tex]8g - 3 = 25\\8g + (-3 + 3) = 25 + 3\\8g = 28\\g = \frac{28}{8}[/tex]

Since [tex]\frac{28}{8}[/tex] equals 3.5, which is the simplest form, that is the answer.

Answer:

  process: substitute the given point values into the 2-point form of the equation for a line

Step-by-step explanation:

There are more than a half-dozen different forms of the equation for a line. They are useful for different purposes. One of them is the "two-point form".

Using x as the independent variable, and y as the dependent variable, the equation can be written as ...

  y -y1 = (y2 -y1)/(x2 -x1)/(x -x1)

where (x1, y1) and (x2, y2) are the two points.

__

Here, your two points are ...

  (t, s) = (10, 337) and (30, 349)

Using s in place of y, and t in place of x, these two points go into the formula like this:

  s -337 = (349 -337)/(30 -10)(t -10)

Simplifying the fraction, this is ...

  s -337 = (12/20)(t -10)

And writing it as a decimal, we get ...

  s -337 = 0.6(t -10)

_____

Additional comments

Adding y1 to both sides of the above form gives you ...

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

This is the form I usually prefer to use, because it can lead directly to slope-intercept form. For this problem, the form shown above gets you to the answer you're looking for.

__

This "two-point form" is an expansion of the "point-slope form", which is ...

  y - k = m(x -h) . . . . . . . line with slope m through point (h, k)

where the equation for slope is ...

  m = (y2 -y1)/(x2 -x1)

and (x1, y1) is used instead of (h, k).

Answer:

The actual linear equation is s= 0.6t + 331 which can be rearranged to make s-337 = 0.6( t-10 ).

Step-by-step explanation:

Any linear equation has the formula y=Mx + c , where x is the independent variable , y is the dependent variable , m is the slope of the line and c is the y-intercept .

here y is replaced by “s” which stands for speed of sound and x is replaced by “t” which stands for temperature.

To find the slope , we divide gain  of “s” by gain of “t “

i.e. [tex]m= \frac{349-337}{30-10}= \frac{12}{20} = 3/5[/tex]

So the slope of the equation is 3/5 Or 0.6

lets plug s=337 and t= 10 into the equation s= 0.6t+ c

[tex]337= \frac{3}{5} (10) + c\\337 = 6 + c\\C= 331\\Hence the equation becomes s= 0.6t+ 331 \\Rearranging the equation , s-331 = 0.6t \\ subtracting 6 from both sides, s-331-6 = 0.6t-6\\S-337 = 0.6 ( t- 10 ) , which is given in your book.\\\\[/tex]

The last line is s-337 = 0.6t - 6 = 0.6(t-10 ) , which is given in your book.

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

When trying to calculate the probability of a sequence of events you need to multiply the probability of the first event happening by the probability of the second event happening. There are a total of 4 numbers (2,3,4,5) and only one is a 2. Therefore the probability of the first pick being a 2 is 1/4. Now there are only 3 cards left (3,4,5) and only 2 numbers are greater than 3 so the probability of picking one of these cards is 2/3. Now that we have both of these probabilities we simply multiply them together.

1/4 * 2/3 = 2/12 or 1/6

Therefore, the probability of picking a 2 and then picking a number greater than 3 is 1/6
