Answer:

The number of students in the seventh grade is 550.

Step-by-step explanation:

To find the number of students in the seventh grade, we need to use the information given in the problem: the number of students in the Environmental Club (11 students) and the percentage of students in the seventh grade that the Environmental Club represents (2%).

We can set up an equation to represent this information:

11 students / 2% = X students / 100%

The left side of the equation represents the number of students in the Environmental Club and the percentage of the seventh grade that they represent. The right side of the equation represents the total number of students in the seventh grade and the percentage that represents the whole.

Since percentages are just fractions with a denominator of 100, we can rewrite the equation as:

11 students / 0.02 = X students / 1

Then, we can use algebraic techniques to solve for X. One way to do this is to cross-multiply:

X = (11 students * 1) / 0.02

= 550 students

Therefore, there are 550 students in the seventh grade.

The required equation of the line is x - y + 3 = 0 which is parallel to line x-y=5.

A straight line's general equation is y = MX + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, the equation of the line will be:

The needed line will have the same slope as the parallel line.

The slope of the parallel line:
x - y = 5

y = x - 5

The parallel line's slope is 1.

Equation of a line with a slope of 1 through the point (-5,-2).

(y - y1) = m(x  x1)

(y + 2) = 1(x + 5)

x - y + 3 = 0

After solving the equations we can conclude that each ticket for an adult costs $24 whereas each ticket for a child costs $6.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, 2 equations can be formed:

Let a be adults and c be children.

3a + 4c = 96 ...(1)

2a + 3c = 68 ...(2)

Now, take equation (1):

3a + 4c = 96

3a = 96 - 4c

a = 96 - 4c/3

Now, substitute a = 96 - 4c/3 in equation (2):

2a + 3c = 68

2(96 - 4c/3) + 3c = 68

96 - 4c/3 + 3c = 68/2

96 - 4c + 3c = 34*3

-c = 102 - 96

c = $6

Now, substitute c = 6 in equation (1):

3a + 4c = 96

3a + 4(6) = 96

3a + 24 = 96
3a = 96 - 24

3a = 72

a = 72/3

a = $24

Therefore, after solving the equations we can conclude that each ticket for an adult costs $24 whereas each ticket for a child costs $6.

Step-by-step explanation:

In the slope-intercept form of the equation of a line (y=mx+b), m equals the slope and b represents the y-intercept.

So, for this problem, m=2 and b=-1.  This means the slope is 2 and the y-intercept is -1.

Answer:

Yes

Step-by-step explanation:

let x = one boy

let y = another boy

let z = a third boy

x + 2 + y + 2 + z + 2 = 15  Combine like terms

6 + x + y + z = 15  Subtract 6 apples from both sides

x + y + x = 9

When we subtract out the 2 apples each brother know that they ate at lease 2 apples each we are left with a total of 9 apples.

One boy could have eaten 4 additional apples?  Yes.

12. The customer should use 120 units in a quarter for company A to be      cheaper.

What is cost management?

Cost management is the process of estimating, allocating, and controlling costs. The cost management process allows a business or a customer to predict future expenses to reduce the chances of budget overrun.

Solution:

Company A charges $14 for first 100 units = 14×100

                                                                        = $1400

After that 11% of 14 = 1.54 per unit

Company B charges $12 per unit so for 100 units = $12×100

                                                                                     = $1200

For company A to be cheaper, customer must use 120 units of electricity from company B as expense for 120 units from company B will be  $12×120 = $1440

and,

For 120 units of electricity from company A would be

$14×100 + 1.54×20 as after 100 units company A will charge 11%.

∴ for 120 units = 1400 + 30.8

                        = $1430.8

13. For taxi company A to be cheaper customer must travel a minimum of 6 miles.

What is cost management?

Cost management is the process of estimating, allocating, and controlling costs. The cost management process allows a business or a customer to predict future expenses to reduce the chances of budget overrun.

Solution:

Given:

Company A charges $2.25 for a minimum of 2 miles journey and after that 85 cents per mile.

Company B charges 95 cents per mile without any minimum mile condition.

Let's assume

no. of miles = 4

fare from A = $2.25(2 miles) + 85 cents(1 mile) + 85 cents(1 mile)

                  = $3.95

fare from B = 95 cents × no. of miles

                  =  95 cents × 4

                  = $3.8

∵ Fare of company A is greater than B, minimum number of miles should be greater than 4.

now,

Let's assume

no. of miles = 5

fare from A = $2.25 + 85 cents + 85 cents + 85 cents

                  = $4.8

fare from B = 95 cents × no. of miles

                  =  95 cents × 5

                  = $4.75

∵ Fare of company A is greater than B minimum number of miles should be greater than 5.

now,

Let's assume

no. of miles = 6

fare from A = $2.25 + 85 cents + 85 cents + 85 cents + 85 cents

                  = $5.65

fare from B = 95 cents × no. of miles

                  =  95 cents × 6

                  = $5.7

∵ Fare of company A is less than B.

∴ Minimum number of miles should be 6.

What is quadratic equation?

Quadratics are often outlined as a polynomial equation of a second degree, which means that it contains a minimum of 1 term that's square. it's conjointly known as quadratic equations.

Main Body:

The actual equation is

h=  4- 18t +16t²

initial height of ball = 4 ft

The problem asks for a time when the ball's height will be 8 ft. To find these times, I plug 8 in for h and solve for t:

8 = 4+18t -16t²

16t² - 18t +4 =0

Using the quadratic equation:

t = {18 ±√((18)² - 4*16 *4 )}/2*16

t = 18 ± √(324 - 256)/32

t = (18 ± √68) /32

t = (18±8.24)/32

t =  0.82 or 0.305
