Answer:

Last year Jules' contract was for 1200 hours.

Step-by-step explanation:

This year Jules has a contract to work for 984 hours.

This is an 18% decrease on the hours on last year's contract.

Last year number: x

This years: 100 - 18 = 82% of last year, which is 984 hours. This means that:

$0.82x = 984$

$x = \frac{984}{0.82}$

$x = 1200$

Last year Jules' contract was for 1200 hours.

A football stadium sells regular and box seating. There are twelve times as many

Vera_Pavlovna [14]

Answer:

There are 801 box seats and 9612 regular seats.

explanation:

Let the number of box seats be x,

Then the regular seats is 12x

The sum of seats equals to 10,413

Solve:

12x + x ➙ 10,413

13x ➙ 10413

x ➙ 801

There are 801 box seats.

Find for regular seats:

➙ 12(x)

➙ 12(801)

➙ 9612

There are 9612 regular seats.

I need a lot of help from the smartest people now right now

Dominik [7]

Answer:

K) I, II, and III

Step-by-step explanation:

Given the quadratic equation in standard form, h = -at² + bt + c, where h is the height or the projectile of a baseball that changes over time, t. In the given quadratic equation, c represents the constant term. Altering the constant term, c, affects the h-intercept, the maximum value of h, and the t-intercept of the quadratic equation.

<h2>I. The h-intercept</h2>

The h-intercept is the value of the height, h, when t = 0. This means that setting t = 0 will leave you with the value of the constant term. In other words:

Set t = 0:

h = -at² + bt + c

h = -a(0)² + b(0) + c

h = -a(0) + 0 + c

h = 0 + c

h = c

Therefore, the value of the h-intercept is the value of c.

Hence, altering the value of c will also change the value of the h-intercept.

<h2>II. The maximum value of h</h2>

The maximum value of h occurs at the vertex, (t, h ). Changing the value of c affects the equation, especially the maximum value of h. To find the value of the t-coordinate of the vertex, use the following formula:

t = -b/2a

The value of the t-coordinate will then be substituted into the equation to find its corresponding h-coordinate. Thus, changing the value of c affects the corresponding h-coordinate of the vertex because you'll have to add the constant term into the rest of the terms within the equation. Therefore, altering the value of c affects the maximum value of h.

<h2>III. The t-intercept</h2>

The t-intercept is the point on the graph where it crosses the t-axis, and is also the value of t when h = 0. The t-intercept is the zero or the solution to the given equation. To find the t-intercept, set h = 0, and solve for the value of t. Solving for the value of t includes the addition of the constant term, c, with the rest of the terms in the equation. Therefore, altering the value of c also affects the t-intercept.

Therefore, the correct answer is Option K: I, II, and III.

Pranay's school is selling tickets to the annual talent show. On the first day of ticket sales the

kozerog [31]

Answer:

Price of senior citizen ticket = $7

Price of student ticket = $5

Step-by-step explanation:

Let:

senior citizen ticket price = a
student ticket price = b

Equations formed :

9a + 10b = 113
2a + 10b = 64

Subtract : Equation 1 - Equation 2

9a + 10b - 2a - 10b = 113 - 64
7a = 49
a = 7

Finding b

2(7) + 10b = 64
10b = 50
b = 5

Solution

Price of senior citizen ticket = $7
Price of student ticket = $5
