Answer:

Adult tickets cost $80, children ticket cost $40

Step-by-step explanation:

Given data

let the number of adults be x

and the number of children be y

so

x+y= 40-------------1

The adult tickets

cost 14 dollars and the children’s tickets cost 12 dollars.

14x+ 12y=  720-------2

solve 1 and 2

x+y= 40

14x+ 12y=  720

from 1

x= 40-y

put this in 2 in place of x

14(40-y)+12y= 720

560-14y+12y= 720

collect like terms

-2y= 720-560

-2y= 160

y= -160/2

y= -80

put y= 80 in 1

x+80= 40

x= 40-80

x= -40

Hence Adult tickets cost $80, children ticket cost $40

Answer:

[tex]V = 97.911in^3[/tex]

Step-by-step explanation:

Given

Shapes: Cube and Cone

Required

Determine the volume

First we calculate the volume of the cube

[tex]V_1 = l^3[/tex]

Where

l = side length = 5.1

[tex]V_1 = 5.1^3[/tex]

[tex]V_1 = 132.651[/tex]

Next, calculate the volume of the cone using:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

Where

h = 5.1

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * 5.1[/tex]

[tex]r = 2.55[/tex]

So, we have:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

[tex]V_2 = \frac{\pi * 2.55^2 * 5.1}{3}[/tex]

[tex]V_2 = \frac{22 * 2.55^2 * 5.1}{7*3}[/tex]

[tex]V_2 = \frac{729.5805}{21}[/tex]

[tex]V_2 = 34.74[/tex]

The volume of the figure is:

[tex]V=V_1 - V_2[/tex]

[tex]V_1 = 132.651[/tex]

[tex]V = 132.651 - 34.74[/tex]

[tex]V = 97.911in^3[/tex]

So i think it would be 1/2 (OR .5), or possibly 2 depending on what its asking.

Every number in X can be multiplied by 2 to receive y, or the numbers in y.

The linear equation would be x*2=y, making the linear function 2, UNLESS you want to take Y and DIVIDE it by 2, making it 1/2, linear equasion would be y*.5=x, or y/.5=2 OR y*1/2=x.

Hope this helps, I'm so sorry if its wrong, I'm not too good at linear functions, I'm pretty sure its 1/2.

Answer:

g(x) = 2f(x) -------> y-intercept at (0,2)

Step-by-step explanation:

There are 36 possible outcomes when rolling 2 dice. The sums range from 2 to 12. There are 4 ways of rolling a 9: 3, 6; 4, 5; 5, 4; 6, 3.

p(sum of 9) = 4/36 = 1/9

1/9 of the rolls are expected to have a sum of 9.

1/9 * 216 = 24

Answer:

There are 5 pigs on Aaron's farm

Step-by-step explanation:

1. Start with 40 animals

2. 1/10 of the animals are cows, so divide 40 by 10 and you will find that 4 of the animals are cows

3. 2/5 of the animals are chickens, so multiple 40 by 2 to get 80 and then divide 80 by 5 and you will find that 16 of the animals are chickens

4. Subtract the 4 cows and 16 chickens from the 40 total animals and you find there are 20 more animals that are neither cows nor chickens

5. Of the 20 remaining animals, 1/4 are pigs, so divide 20 by 4 and you will find that there are 5 pigs

Answer:

There are 5 pigs on Aaron's farm

Answer:

Step-by-step explanation:

slope of red line=(-4-4)/(2-0)=-8/2=-4

eq. of red line is y-4=-4(x-0)

y=-4x+4

put x=0,y=0

0=0+4

which is true if 0<4

so y<-4x+4

The linear inequality represents the graph fr the coordinates (0,4), (2,-4) is y < -4x + 4.

Expressions with linear inequalities compare any two values using inequality symbols like "<",  ">" , "≤" or "≥" These values could be either numerical, algebraic, or both.

Calculation for linear inequality shown by graph:

The coordinates of the straight line are  (0,4), (2,-4).

Substitute the value in equation shown in option C.

y < -4x + 4

For points (0,4), put x = 0 and find y.

y < -4×0 + 4

y = 4 , which is satisfied.

Now consider points (2, -4)

Put x = 2 in the same equation and find y.

y < -4×2 + 4

y = -4 ( which again satisfies the given value for y)

Therefore, the equation y < -4x + 4 satisfies the points given for straight line.

Answer:

A fraction should show a part-to-whole comparison./A

Step-by-step explanation:

have a good day ^^

Answer:

a. A fraction should show a part-to-whole comparison.

Step-by-step explanation:

Answer:

a. 0.4

b. 0.6

c. 0.6493

Step-by-step explanation:

p(checking work email) = p(A) = 0.40

p(staying connected with cell phone) = p(B) = 0.30

p(having laptop) = p(c) = 0.35

p(checking work mail and staying connected with cell phone) = p(AnB) = 0.16

p(neither A,B or C) = p(AuBuC)

= 1-42.8%

= 0.572

p(A|C) = 88% = 0.88

p(C|B) = 70% = 0.7

a. What is the probability that a randomly selected traveler who checks work email also uses a cell phone to stay connected?

p(B|A) = p(AnB)/p(A)

= 0.16/0.4

= 0.4

b. What is the probability that someone who brings a laptop on vacation also uses a cell phone to stay connected?

p(B|C) = P(C|B)p(B)/p(C)

= 0.7x0.3/0.35

= 0.6

c. If the randomly selected traveler checked work email and brought a laptop, what is the probability that he/she uses a cell phone to stay connected?

p(A|BnC)

= P(BnAnC)/p(AnC)

= p(AnC) = p(A|C).p(C)

= 0.88x0.35

= 0.308

p(AnBnC) = p(AuBuC)-p(a)-p(b)+ p(AnB)+p(AnC)+p(BnC)

p(BnC) = 0.7x0.3

= 0.21

p(AnBnC) = 0.572-0.4-0.3-0.35+0.16+0.308+0.21

= 0.2

p(A|BnC) = 0.2/0.308

= 0.6493

Answer:  Choice A. sin(A) = cos(B)

============================================================

Explanation:

The rule is that sin(A) = cos(B) if and only if A+B = 90.

Note how

Since both result in the same fraction BC/AB, this helps us see why sin(A) = cos(B). Similarly, we can find that cos(A) = sin(B).

In the diagram below, the angles A and B are complementary, meaning they add to 90 degrees. So this trick only applies to right triangles.

The side lengths can be anything you want, as long as you're dealing with a right triangle.

Answer:percent increase in cupcake sales from Friday to Saturday= 34%

Step-by-step explanation:

 Step 1

Percent increase = Increase in cup cakes/ Old amount of cupcakes x100

Cupcakes sold on Friday = 19 3/4

Cupcakes sold on  Saturday = 261/2

Increase in sales =26 1/2 -- 19 3/4  ( we will change to decmal for easy solving)

=26.5 - 19.75= 6.75 or 6 3/4

Step 2

Percentage increase = (6 3/4)/ (19 3/4)  x100

Percentage increase = 6.75/19.75 x 100

Percentage increase =0.341 x100 = 34%
