can someone help me ? and can you also explain how u got the answer ?

Given:

She purchased adult ticket for herself and children tickets for her 2 boys.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

To find:

The expression to represent the total cost of the tickets Jenny purchased.

Solution:

Let x represent the number of adult ticket purchase

and y represent the number of child tickets purchase.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

Total cost = 39.99x + 19.99y

Therefore, the expression for total cost is 39.99x + 19.99y.

She purchased one adult ticket and 2 child tickets.

Substitute x=1 and y=2 in the above expression.

Total cost = 39.99(1) + 19.99(2)

               = 39.99 + 39.98

               = 79.97

Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

Step-by-step explanation:

Answer:

third option

Step-by-step explanation:

Given that x = - 2 + [tex]\sqrt{8}[/tex] is a root

Complex roots always occur as conjugate pairs , thus

x = - 2 + [tex]\sqrt{8}[/tex] is a root then x = - 2 - [tex]\sqrt{8}[/tex] is a root

The required factor is then

(x - (- 2 - [tex]\sqrt{8}[/tex] ) )

Answer:  y= 1/5 x + 8

Step-by-step explanation:

To get a perpendicular line, take the reciprocal of the original "m" in the equation and reverse the sign.

- 5 becomes +1/5

Then substitute the y and x values from the given coordinate into the new equation and solve for b

y= mx+b

6=1/5 (-10) + b

6 = -2 +b

8 = b   rewrite the new equation and substitute  8 for b

y= 1/5 x + 8

The attached screenshot shows the lines and the point.

Answer:

y= -1/3 + 13/3

Step-by-step explanation:

y-2=-1/3(x-7)

Use the distributive property to simplify the right side of the equation

y-2=(-1/3 * x) + (-1/3 * -7)

y-2=-1/3x + 7/3

Add 2 to both sides get the y by itself. 2 can be expressed as 6/3

(y-2) + 2=(-1/3x + 7/3) + 6/3

y= -1/3x + 13/3

c would then equal 33, which is greater than 30

Answer:

12/sin5°

Step-by-step explanation:

This angle can be calculated using the law of sine:

sin(angle)=opposite cathete/hypothenuse

sin(angle)=wall/ladder

In this exercise we want to calculate the length of the hypotenuse (ladder), so the equation is changed afterwards.

sin(angle)=wall/ladder

sin(angle)*ladder=wall

ladder=wall/sin(angle)

Now the given values are used:

ladder=wall/sin(angle)

ladder=12ft/cos(51°)

Answer:

1 = 45

3 = 45

Step-by-step explanation:

[tex]\angle {1}[/tex] and [tex]\angle {3}[/tex] is 45 degrees since the unmarked angle is 90 degrees, meaning that BOTH [tex]\angle {1} and \angle {3}[/tex] are equal.

Answer:

2,095,426.517

Step-by-step explanation:

From the question above we are required to find the product of 698475.50585057 and 3

Therefore the product can be calculated as follows

698475.50585057 × 3

= 2,095,426.517

Hence 698475.50585057 multiplied by 3 is 2,095,426.517

Answer:

The domain is continuous and the weight y of x identical hardcover books

Step-by-step explanation:

Discrete means non continuous data. This is continuous and equal so the domain is continuous.

Also, precipitation each week can vary so that won't work. Eating carrots each day can also vary so that doesn't work. The cost of an item can vary almost every day! So that is not true.

Therefore it is the last one, because it is identical and all of the coordinates make (1,3).

Hope this helps! :)

Answer:

C

Step-by-step explanation:

Because when you multiply 4³ × 4^4 = 16384

And 4^9 = 262144

(divide) 16384/262144 = .0625

.0625 = [tex]\frac{1}{16}[/tex]

[tex]\frac{1}{4^2}[/tex] = [tex]\frac{1}{16}[/tex]

because 4 * 4 = 16

Answer:

By plotting points A', B' and C' we can get the dilated image A'B'C'.

Step-by-step explanation:

Let the point P is origin (0, 0), segment AB lies on the x-axis and segment PC on the y-axis,

Coordinates of A, B and C will be (1, 0), (2, 0) and (0, 2).

When triangle ABC is dilated by a scale factor 4 about the origin,

Rule for dilation;

(x, y) → (4x, 4y)

New coordinates of the points A, B and C will be,

A(1, 0) → A'(4, 0)

B(-2, 0) → B'(-8, 0)

C(0, 2) → C'(0, 8)

Answer:

Correct

Step-by-step explanation:

New coordinates of the points A, B and C will be,

A(1, 0) → A'(4, 0)

B(-2, 0) → B'(-8, 0)

C(0, 2) → C'(0, 8)

Answer:

298

Step-by-step explanation:

29.8 is 10 times as much as 298

The required proportion value is 2.98 which is equal to one-tenth of 29.8.

Given that,
To determine 29.8 is 10 times as much as a number.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number be x,

According to the question.
29.8 = x10
x = 29.8 / 10x
x = 2.98

Thus, the required proportion value is 2.98 which is equal to one-tenth of 29.8.

Answer:

$840

Step-by-step explanation:

First, multiply 70 by $150 to get the total amount the Alonzo earned

70 x 150 = 10,500

Then, multiply 10,500 by 1.08 to find the total amount made with commissions.

10,500 x 11,340

Finally, subtract 10,500 from 11,340 to find the amount of money earned from commissions.

11,340 - 10,500 = 840

Answer:

$840

Step-by-step explanation:

Start by finding the total profit made:

70 • $150 = $10500

Then multiply the total by the commission rate, %8, which is equal to 0.08:

$10500 • 0.08 = $840

The answer is $840

Answer:

56:8:48

Step-by-step explanation:

1] add th eratio numbers together

7+1+4=12

2} write the ratio as fractions

7/12  1/12  4/12

3] use the formula (ration number/total number * number of sheeps)

a] 7/12 * 96 = 56

b] 1/12 * 96 = 8

c] 4/12 * 96 = 48

3] write your answer as a ration

7 : 1 : 4 = 56 : 8 : 48

Answer:

The answer is 56 : 8 : 32

Step-by-step explanation:

7 + 1 + 4 = 12

7/12 x 96 = 56

1/2 x 96 = 8

4/12 x 96 = 32
