Since the beginning of the month a local reservoir has been losing water at a constant rate. On the 10th of the month, the reservoir held 300million gallons of water and on the 18th it held only 262 million gallons. A. Write an equation that will give the amount of water in the reservoir at any time B. Hov, much water was in the reservoir on the 14th of the month? C. When will the reservoir get empty?​

Answer:

$ 1.725

Step-by-step explanation:

4 Pack of coffee = $ 6.90

1 Pack of coffee = $ 6.90 / 4 = $ 1.725

( The word per means " 1 " )

Answer:

$1.73

Step-by-step explanation:

To get the price of one bottle, set up a proportion.

let x = the price of one bottle

the numerator will be the price of the bottles and the denominator will be the number of bottles.

6.90 / 4  = x / 1

cross multiply: 6.90 = 4x

solve for x by dividing by 4 on both sides

6.90/4 = 4x / 4

x = 1.725, round up to $1.73

Answer:

r = d/2

r = 10.2/2 = 5.1

The distance between two parallel lines  y=x+3 and y=x+1 will be equal to

[tex]d=\dfrac{1}{\sqrt{2}}[/tex]

The lines which do not intersect to each other and only intersect at infinity are called parallel lines.

Here we have two lines:-

y=x+3

y=x+1

The formula for the distance between two parallel lines is given by:-

[tex]d=\dfrac{|C_1-C_2|}{\sqrt{a^2+b^2}}[/tex]

We have C1=3 C2=1 a=1 b=1 by putting the value in the formula we will get:-

[tex]d=\dfrac{3-2}{\sqrt{1^2+1^2}}=\dfrac{1}{\sqrt{2}}[/tex]

Hence distance between two parallel lines  y=x+3 and y=x+1 will be equal to  [tex]d=\dfrac{1}{\sqrt{2}}[/tex]

Number of males not enrolled

Number of females not enrolled

(a)

The table based on data is

                Enrolled        Not enrolled      Total  

Male            82                  36                     118

(b)

Percentage of students were males that went to magic college

(c)

Percentage of females went to magic college

Answer:

a)  see below

b)  29.7%  (1 d.p.)

c)  64.6%  (1 d.p.)

Step-by-step explanation:

Part (a)

Using the given information to create a two-way table:

B. It could be costly to initially switch to.

A disadvantage of renewable energy would be It could be costly to initially switch to. Hence option B is true.

Used the definition of renewable energy that states,

Renewable energy is energy that comes from a source that won't run out. They are natural and self-replenishing and usually have a low- or zero-carbon footprint.

Now, Renewable energy sources have numerous advantages, such as being environmentally friendly and sustainable, one of the disadvantages is the initial high cost of transitioning from traditional energy sources to renewable ones.

Since renewable energy sources do not create large amounts of pollution.

Additionally, renewable energy has the potential to produce ample power to meet our needs.

Finally, the fact that renewable energy will not run out is actually an advantage, not a disadvantage.

Hence, Option B is true.

Answer:  30 students: $346.5

1 student: $11.55

Step-by-step explanation:

The total cost in dollars for admission and lunch for 30 students is $406.6 and for each student is $13.55.

The unitary method is a technique for solving a problem by first finding the value of single unit, and then finding the value the necessary value by multiplying the single unit.

According to the given question

Cost price for five students for taking admission to the museum and lunch is 36.25 and 31.50 respectively.

cost price for one student for taking admission in museum = [tex]\frac{36.25}{5} = $7.25[/tex]

cost price for one student lunch = [tex]\frac{31.50}{5} = 6.3[/tex]

Therefore,

The total cost for each student for the admission and lunch = 7.25+6.3 =

$13.55

And, the total cost for 30 students for admission and lunch = 30×$13.55 =$406.5

Hence, the total cost for admission to museum and lunch for each student is $13.55 and for 30 students is $406.6.

Answer: [tex]x < 8\\[/tex]

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Interval Notation: (-∞, 8)

The equivalent inequality to 5(2x-6)+6(3-x)<2x+4 is x < 8.

Let's simplify the given inequality step by step:

Original inequality: 5(2x - 6) + 6(3 - x) < 2x + 4

Distribute the constants inside the parentheses:

10x - 30 + 18 - 6x < 2x + 4

Combine like terms on the left side:

(10x - 6x) - 30 + 18 < 2x + 4

4x - 12 < 2x + 4

Subtract 2x from both sides to isolate the x terms on the left side:

4x - 2x - 12 < 4

Simplify:

2x - 12 < 4

Now, add 12 to both sides:

2x - 12 + 12 < 4 + 12

2x < 16

Finally, divide both sides by 2:

2x / 2 < 16 / 2

[tex]\huge\purple{ x^2 +(y+2)^2 = 4}[/tex]

Step-by-step explanation:

Circle is centred at (0, -2)

-> h = 0 & k = - 2

radius of the circle (r) = y-coordinate of the center = - 2

Equation of circle in standard form is given as:

[tex](x-h)^2 +(y-k)^2 = r^2[/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex](x-0)^2 +[y-(-2)]^2 = (-2)^2[/tex]

[tex]\implies\huge\orange{ x^2 +(y+2)^2 = 4}[/tex]

This is the required equation of circle.

Given that the particle is in equilibrium, the value of p = 2.5 and the value of q = -1.5

To answer the question, we need to know what force are

A force that thing which cause a change in motion of an object

Since there are three forces (15i + j) N, (5qi – pj) N and (-3pi - qj) N, where p and q are constants, act on a particle. Given that the particle is in equilibrium, the resultant force on the particle is zero.

A resultant force is a vector sum of two or more forces

So,  (15i + j) N + (5qi – pj) N + (-3pi - qj) N = 0i + 0j

15i + 5qi - 3pi + j - pj - qj = 0i + 0j

(15 + 5q - 3p)i + (1 - p - q)j = 0i + 0j

Equating components, we have

15 + 5q - 3p = 0 and 1 - p - q = 0

5q - 3p = -15 (1) and - p - q = -1

5q - 3p = -15 (1) and p + q = 1 (2)

From equation (2), p = 1 - q (3).

Substituting p into (1), we have

5q - 3p = -15 (1)

5q - 3(1 - q) = -15

5q - 3 + 3q = -15

5q + 3q = -15 + 3

8q = -12

q = -12/8

q = -3/2

q = - 1.5

Substituing q into (3), we have

p = 1 - q

p = 1 - (-3/2)

p = 1 + 3/2

p = (2 + 3)/2

p = 5/2

p = 2.5

So, the value of p = 2.5 and the value of q = -1.5
