Answer:

Julie Spends $5.62, Micah spends $28.10 and Jeremy Spends $34.82

Step-by-step explanation:

If Micah spends 5 times as much as Julie, that is $28.10 because 5.62 x 28.10 = 28.10. If Jeremy spends 6.72 more than Micah, you would do 28.10 + 6.72, which is 34.82

After setting aside 4 hours for sports, Burt has 6 hours left for television. Since each movie is 2 hours, Burt can watch 3 two-hour movies in the remaining time.

Burt's parents allow him a total of 10 hours of television per week. Since he is planning to watch four hours of sports, we subtract this amount from the total to find the time remaining for watching movies. Here's how we solve for the number of movies Burt can watch:

Total TV time allowed: 10 hours per week

Time planned for watching sports: 4 hours

Time remaining for movies: 10 hours - 4 hours = 6 hours

Since each movie is two hours long, we then divide the remaining time by the length of one movie:

6 hours divided by 2 hours/movie = 3 movies

Therefore, Burt is planning to watch three two-hour movies this week.

Answer:

The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12

Step-by-step explanation:

Let

x ----> the number of general admission tickets sold

y ----> the number of VIP tickets sold

we know that

[tex]x+y=33[/tex] ---> equation A

[tex]70x+105y=2,730[/tex] ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both lines

using a graphing tool

The solution is the point (21,12)

see the attached figure

therefore

The number of general admission tickets sold was 21 and the number of VIP tickets sold was 12

Final answer:

To solve how many general admission and VIP tickets John sold, a system of equations is formed and solved, revealing that John sold 21 general admission tickets and 12 VIP tickets.

Explanation:

John is selling tickets to an event with two different pricing options, general admission tickets at $70 and VIP tickets at $105. He sold a total of 33 tickets resulting in revenue of $2730. To determine how many of each type of ticket he sold, we will use a system of equations.

Let x represent the number of general admission tickets sold and y represent the number of VIP tickets sold. We can then form the following two equations based on the information provided:

x + y = 33 (equation 1: total number of tickets sold)

70x + 105y = 2730 (equation 2: total revenue from ticket sales)

To solve this system, we can use the method of substitution or elimination. Here, we'll use substitution for simplicity. First, solve equation 1 for x:

x = 33 - y

Substitute this expression for x in equation 2:

70(33 - y) + 105y = 2730

Simplify and solve for y:

2310 - 70y + 105y = 2730

35y = 420

y = 12

Since y = 12, substitute y back into equation 1 to find x:

x = 33 - 12 = 21

Therefore, John sold 21 general admission tickets and 12 VIP tickets.

The value of [tex]f(x+2)=2.1x+2.5[/tex]

Step-by-step explanation:

Given: The function [tex]f(x)=2.1x-1.7[/tex]

Using this formula, we need to find the value of [tex]f(x+2)[/tex]

Hence, we need to substitute [tex]x[/tex] by [tex]x+2[/tex] to find the value of [tex]f(x+2)[/tex]

[tex]f(x+2)=2.1(x+2)-1.7[/tex]

Multiplying the term [tex](x+2)[/tex] by [tex]2.1[/tex], we get,

[tex]f(x+2)=2.1x+4.2-1.7[/tex]

Adding the constant term,

[tex]f(x+2)=2.1x+2.5[/tex]

Thus, the value of [tex]f(x+2)[/tex] is [tex]f(x+2)=2.1x+2.5[/tex]

What are linear equalities in one variable?

The linear equation in one variable is an equation that is expressed within the form of ax+b = zero, where a and b are integers, and x is a variable and has only one answer.

Conclusion: For example, 2x+3=8 is a linear equation having a single variable in it. therefore, this equation has only one solution, which is x = 5/2.

let the auditorium sell x seats for 8 dollars per seat.

In addition to that auditorium made 300 dollars.

The total money earned by the auditorium by selling x seats and the addition of 300 dollars is 2772 dollars.

8x + 300 = 2772

8x = 2772 - 300

8x = 2472

x = 2472/ 8

x = 309

The above question is an example of linear equalities in one variable.

Final answer:

Using substitution, we solve the equation 6x + 6y = 0 for y, yielding y = -x. Substituting into -7x + 2y = 18 and solving for x gives x = -2. Substituting x back into y = -x, we find y = 2.

Explanation:

To solve the system of equations using substitution, we can isolate one variable in one equation and then substitute it into the other equation. In this case, we've been given the system:

-7x + 2y = 18

6x + 6y = 0

From the second equation, we can isolate y:

6x + 6y = 0

x + y = 0

y = -x

Now, substitute y = -x into the first equation:

-7x + 2(-x) = 18

-7x - 2x = 18

-9x = 18

x = -2

Now that we have the value for x, we can substitute it back into y = -x to find y:

y = -(-2)

y = 2

The solution to the system is x = -2 and y = 2.

Answer:

d) 729cm^3

Step-by-step explanation:

Length =27cm

Width = 1/3 of length

= 1/3 of 27cm = 1/3 × 27cm = 9cm

Height = 1/3 of width

= 1/3 of 9cm = 1/3 × 9cm = 3cm

Thus, length = 27cm; width = 9cm; height = 3cm

Hence, volume = length × width × height

= 27cm × 9cm × 3cm

= 729cm^3

Volume is a three-dimensional scalar quantity. The volume of the box is 729 cm³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a room or box that is the shape of a rectangular prism is calculated by multiplying the length, width, and height of the prism.

Volume = Length × Width × Height

Given that length of the box is 27 cm. Also, it is mentioned that the width of a box is one third of its length. Therefore, the width of the box is,

Width of the box = (1/3) × 27cm = 9cm

Further, the height of the box is one third of its width. Therefore, the height of the box is,

Height of the box = (1/3) × 9cm = 3 cm

Furthermore, the volume of the box can be written as,

Volume of the box = Length × Width × Height

                               = 27cm × 9cm × 3cm

                               = 729 cm³

Hence, the volume of the box is 729 cm³.

Answer:

15.5 seconds.

Step-by-step explanation:

From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.

During this time the car slowed  down from 8 m/s to 0 m/s.

Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant  acceleration:

s = (u + v)t / 2   where u = initial velocity, v = final velocity, s = distance and t = the time, so:-

62 = (8 + 0)t/ 2

62 = 8t/2

4t = 62

t = 15.5 seconds.

5/8

Step-by-step explanation:

First, you need to find a common denominator. In this case, the common denominator is 8. To change the second fraction into a fraction that you can easily subtract, you have to multiply the second fraction by 2/2 (which simplifies to one, so you're not changing the value of the fraction at all). Now, the equation reads, 7/8 - 2/8. From here, you just need to subtract the numerators, which ends up being 5/8.

Answer:

B. 5/8

Step-by-step explanation:

Between 7/8 and 1/4, the common denominator is 2. By multiplying 1/4 by 2, you'll get 5/8 after subtracting 2/8 from 7/8.

The answer is in the picture below. :)

Step-by-step explanation:

Answer:

8  rows of trees are there in the parcel.

Step-by-step explanation:

The number of trees planted in each row  = (3 x -2) trees

The total number of trees planted on  the land  = (24 x - 16)

Let us assume the total number of rows planted = m

Now,as we know:

The plants in each row x The number of rows = Total trees Planted

⇒   (3 x -2)  x (m)  =   (24 x - 16)

[tex]\implies m = \frac{24x-16}{3x-2}[/tex]

Simplifying for the value of m, we get:

[tex]m = \frac{24x - 16}{3x-2} = \frac{8(3x-2)}{3x-2} = 8\\\implies m = 8[/tex]

Hence,  the total number of rows planted = 8

Step-by-step explanation:

You can observe in the picture given in the exercise that  [tex]\angle E[/tex] is formed by two secants intersecting outside the circle.

It is necessary to remember that, by definition:

[tex]Angle\ formed\ by\ two\ Secants=\frac{1}{2}(Difference\ of\ Intercepted\ Arcs)[/tex]

You can also identify that the Intercepted Arcs are the following:

[tex]CD=110\°\\\\AB=30\°[/tex]

Then, knowing the measures of the Intercepted Arcs, you can substitute them into the equation shown before and then evaluate, in order to calculate the measure of  [tex]\angle E[/tex] , which is the angle formed by the intersection of the secants.

Therefore, you get:

[tex]m\angle E=\frac{1}{2}(110\°-30\°)\\\\m\angle E=40\°[/tex]

Step-by-step explanation:

Answer:

B. 0.38

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

The variable x is in the base position so it is not exponential..

An exponential function is where the exponent is the variable , like for example 2^x.

The function f(x) = x^-3.141 is not an exponential function because in an exponential function, the base must be constant, and here x is the exponent, not the base.

The function f(x) = x−3.141 is not an exponential function. In an exponential function, the base is a constant and the exponent is the variable. Since the variable x is in the exponent here and the base is not a constant, we do not have an exponential function according to the definition.

Therefore, the correct answer is A: This is not an exponential function because the variable is in the base position and not in the exponent where we typically find the variable in exponential functions.

The fifth angle is 108 degrees

Solution:

Given that a pentagon has angle of 104, 102, 115 and 111 We have to find the angle of fifth angle

A pentagon is a five sided polygon

The sum of all the interior angles of a pentagon is 540 degrees

Given that,

Angle 1 = 104

Angle 2 = 102

Angle 3 = 115

Angle 4 = 111

Angle 5 = ?

Let the angle be "x"

So to find the fifth angle, add all the angles and equate to 540 degrees

Angle 1 + Angle 2 + Angle 3 + Angle 4 + Angle 5 = 540

104 + 102 + 115 + 111 + x = 540

432 + x = 540

x = 540 - 432

x = 108

Thus the fifth angle is 108 degrees
