Ok what do you specifically do you need help with. While working with similar triangles there is a ratio that they dilate by ex: 1:2 could turn into 2:4

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu

dolphi86 [110]

Answer:

The monthly cost for 9 HCF is $38.54

Step-by-step explanation:

The graph is missing; however, the question can still be solved

Given

Slope = 1.55

When monthly cost = $47.84, Amount of water = 15 HCF

Required

Determine the monthly cost for 9 HCF

From the question, we understand that it is a linear function;

Linear functions are of the form

$y = mx + b$

Where y is the function of x and m is the slope

In this case; the function is the monthly water bill

and x is the amount of water

Solving for b

When monthly cost = $47.84, Amount of water = 15 HCF

The function is as follows;

$47.84 = 1.55 * 15 + b$

$47.84 = 23.25 + b$

Subtract 23.25 from both sides

$47.84 - 23.25= 23.25 - 23.25 + b$

$24.59 = b$

$b = 24.59$

Solving for the monthly cost for 9 HCF

Here, we have that

$x = Amount\ of\ water = 9$

$m = Slope = 1.55$

$b = 24.59$

Substitute these values in the linear function; $y = mx + b$

$y = 1.55 * 9 + 24.59$

$y = 13.95 + 24.59$

$y = 38.54$

Hence, the monthly cost for 9 HCF is $38.54

Hi I need help in this question

dalvyx [7]

Answer:

First part representing requirements for the length x>=5 ft

Second part yes

Step-by-step explanation:

Well, the formula for finding the area of a rectangle is l x w. In the question, it states that the pen must be 4 ft wide and to fit his requirements of the pen being at the minimum 20 ft^2 we have this inequality 4x>=20 which we must solve and we get x>=5 which means that this represents all of the possible lengths for the play space. For the second part, we know that to fufill Judah's requirements for square ft., our length must be greater than or equal to 5. Last time I was doing math, I'm pretty sure 5 1/2>5 which thus can be accepted as a length value, still meeting the requirements of at least 20ft^2 space for the play space.
