Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a thickness of 3 inches. At what rate was the ice growing over these 8 days in inches per day?

Answer:

pair of jeans = 21  

shirt = 30.5

Step-by-step explanation:

Let the cost of each pair of jeans be $ x, and the cost of each shirt be $ y.

Since, cost of each pair of jeans is $ x, the cost of 5 pair of jeans will be $ 5x and cost of 2 shirts will be $ 2x.

Likewise, the cost of each pair of jeans is $ x, so the cost of 3 pair of jeans will be $ 3x and cost of 4 shirts will be $ 4y.

5 pair of jeans and 2 shirts for $166. This means:

            Equation 1:    5x + 2y = 166                                            

3 pair of jeans and 4 shirts for $164. This means:

                               2x + 4y = 164

Dividing both sides by 2, we get:

           Equation 2:      x + 2y = 82                                            

Subtracting Equation 2 from Equation 1, we get:

5x + 2y - (x + 2y) = 166 - 82

5x + 2y - x - 2y = 84

4x = 84

y = 30.5

Using the value of x, in Equation 2, we get:

21 + 2y = 82

2y = 61

y = 30.5

Since, x represents the cost of pair of jeans, the cost of each shirt is $ 16.

y represents the cost of sweater, so the cost of each sweater is $ 33.

c) Ethan earned $120.25 for working a 6.5h shift.

Answer:

w= -1

Step-by-step explanation:

-1.01 = 1.4(w + 2) - 2.41

add 2.41 to both sides

1.4 = 1.4(w + 2)

divide by 1.4 on both sides

1=w+2

subtract 2 on both sides

-1 =w

Answer: 10.5 small boxes

Step-by-step explanation:

y = - 4/3 x - 20/3

Step-by-step explanation:

x = - 3/4 y - 5   Move Terms

3/4 y = - 5 - x   Divide both sides

y = - 20/3 - 4/3 x     Reorder the terms

y = - 4/3 x - 20/3

Hint :- The slope intercept form of the line is [tex] y = mx + c [/tex] , where m is the slope of the line and c is y intercept .

Solution:-

Given equation to us ,

[tex]\implies x = \dfrac{-3}{4}y -5 [/tex]

Multiply both sides by 4 ,

[tex]\implies 4x = -3y -20 [/tex]

Add 20 to both sides ,

[tex]\implies 4x +20 = -3y [/tex]

Divide both the sides by -3 ,

[tex]\implies \dfrac{-4}{3}x-\dfrac{20}{3}= y [/tex]

Flip the equation ,

[tex]\implies y = \dfrac{-4}{3}x-\dfrac{20}{3} [/tex]

Answer:

0.046875 aka 3/64

Step-by-step explanation:

In a geometric sequence, each term will be related to the previous term by undergoing either multiplication or division.

In this case, each case is exactly 1/2 of the previous term. 12 is half of 24, and 6 is half of 12. By continuing this sequence, we get

1: 24

2: 12 (24 * 1/2)

3: 6 (12 * 1/2)

4: 3 (6 * 1/2)

5: 3/2 (3 * 1/2)

6: 3/4 (3/2 * 1/2)

7. 3/8 (3/4 * 1/2)

8. 3/16 (3/8 * 1/2)

Answer:

x=26.6 when y=8

Step-by-step explanation:

y=Kx, k=y/x, when y is 3 and x is 10,

k=3/10= 0.3

but when y is 8, x will be given by

x=y/k

x=8/0.3

x=26.6 approximately 27

Answer:

x = 8

Step-by-step explanation:

2x = 18 - 2 , that is

2x = 16 ( divide both sides by 2 )

x = 8

Answer:

Answer:

The answer is B 10 L

Step-by-step explanation:

let milk and water in the mixture be 7x and 4x equal 55L

[tex]7x + 4x = 55 \\ 11x = 55 \\ x = 5[/tex]

[tex]7(5) = 35l \: milk \\ 4(5) = 20l \: water[/tex]

let x Liters of water he added so that the ratio is 7:6

[tex] \frac{35l \: milk}{20l \: water + x} = \frac{7}{6} [/tex]

cross multiply

[tex]35l \: milk \times 6 = (20l \: water + x)7 \\ 210l \: m= 140l \: w + 7x \\ 210l \: m - 140l \: w = 7x \\ 70l = 7x \\ \frac{70}{7} = \frac{7x}{7 } \\ x = 10 l \: water[/tex]

Answer:

Table:

1: f(x) = 5

2: f(x)= 6

5: f(x) = 9

Points: (1,5), (2,6), and (5,9)

Step-by-step explanation:

1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.

Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.

2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:

Therefore, the points are (1,5), (2,6), and (5,9).

Answer:

Step-by-step explanation:

The perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

The coordinates are given as:

(−4,4), (−4,1), and (−8,−4).

Calculate the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(-4 + 4)^2 + (4-1)^2} = 3[/tex]

[tex]BC = \sqrt{(-4 + 8)^2 + (1+4)^2} = \sqrt{41[/tex]

[tex]AC = \sqrt{(-4 + 8)^2 + (4+4)^2} = \sqrt{80[/tex]

The perimeter is the sum of the side lengths.

So, we have:

[tex]P = 3 + \sqrt{41} + \sqrt{80}[/tex]

Expand

[tex]P = 3 + \sqrt{41} + 4\sqrt{5}[/tex]

Hence, the perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units
