Answer:

1.5 or 6/4

Step-by-step explanation:

y=1.5x+2

or

y=6/4x+2

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

Let x represent the amount of second chocolate that should be added.

First, 300 pounds of chocolate

1 to 7 = chocolate to caramel

Hence there are a total of eight pieces (1+7=8).

There are:

1/8 300 pounds cocoa

7/8 300 pounds caramel

Second chocolate: x pounds cocoa to caramel = 1 to 15 Hence, there are in total 16 parts (1+ 15 = 16)

There are:

Caramel: 15/16" x pounds Cocoa: 1/16" x pounds

Chocolate yield: 300 + x pounds

1 to 9 = chocolate to caramel

As a result, there are a total of ten pieces (1 + 9 = 10)

There are:

1/10 (300 + x) pound cocoa

9/10 (300 + x) pounds caramel

Because there is only one part cocoa in every chocolate, adding up the amounts of cocoa is simple:

1/8* 300+ 1/16* x = 1/10 * (300 + x)

300/8 + x/16 300/10 + x/10 =

75/2 + x/16 = 30 + x/10

75/230= x/10 - x/16

75/2 - 60/2 = 8x/80 - 5x/80

(75 - 60)/2 = (8x - 5x)/80

15/2 = 3x/80

80 15/2 = 3x

40 * 15 = 3x

600 = 3x

x = 600/3

200 pounds = x

As a result, the answer is 200.

Answer:

example: 120 minutes divided by 60 so you divide by 60

Step-by-step explanation:

Answer:

To convert minutes to hours, we must multiply the number of minutes by 60, because that is how many minutes there are in an hour.

Answer:

48°

Step-by-step explanation:

Overall, it's 360°. If you add 90° (the right triangle), x°, x°, 2x, 30°, and x° you will get 5x + 120. Subtract 120 from 360, and you will get 240. Once you get 240, you divide by 5, to solve for x.

Answer:

x = 60 Degrees

Step-by-step explanation:

Using the vertical angle theorem -->

we can conclude Ang. COB = Ang. AOD -->

Convert into an equation -->

30 + 2x = 90 + x

Combine like terms and solve

2x = 60 + x

x = 60

--> thus, x is equal to 60 degrees

Answer:

F : y = -x + 4

Step-by-step explanation:

The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)

Such a line has negative slope

Equation will be of the form

y = mx + b where m is a negative number

We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction

Let's examine options F and G

F:  y = - x + 4
G: -9x + 3

Plug in some values for x from the graph and see which of the lines comes closest to the  y values  computed from the equations

At x = -5, the y value from the graph appears to be either 7 or 8

F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value

G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value

At x = 0; the y value from graph is close to 4

From the equations we get
F: y = -x + 4 ==>  y = -(0) + 4 = 4; pretty darn close

G: y  -9x + 3 => y = -9 + 3 = -6; large difference

One more point
At x = 20, the point on the graph appears to be close to -19

From the equations we get

F: y = -x + 4 = -20 + 4 = -16; not too different

G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off

So the best line of fit would be

F : y = -x + 4

The equation that best represents the line of fit from the scatter plot is given as follows:

y = -x + 4.

The slope-intercept representation of a linear function is given by the equation shown as follows:

y = mx + b

The coefficients m and b have the meaning presented as follows:

From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:

b = 4.

When x = 20, y is approximately -16, hence the slope m is obtained as follows:

-16 = 20m + 4

20m = -20

m = -1.

Hence the function is:

y = -x + 4.

Answer:

4 sqrt(2) =c

Step-by-step explanation:

The base is the triangle

We can use the Pythagorean theorem to solve

a^2 + b^2 =c^2  where a and b are the legs and c is the hypotenuse

4^2 + 4^2 = c^2

2 * 4^2 = c^2

Take the square root of each side

sqrt(2 * 4^2) = sqrt(c^2)

sqrt(2) *sqrt( 4^2) = c

4 sqrt(2) =c

Answer:

Step-by-step explanation:

Surface area is the sum of the areas of all the sides.

The bottom side(the rectangle with dimensions 11.9 and 17.4): 11.9 * 17.4 = 207.06 * 1 = 207.06(because there is only one of this shape)

The rectangular sides(dimensions 10.5 and 14): 10.5 * 14 = 147 * 2 = 294 for both sides

The triangular sides(17.4 and 7): (17.4 * 7) / 2(because it a triangle) = 60.9 * 2 = 121.8(because there are two sides)

Add these up to get your surfacce area
