Answer:

1. $6000

2. 40.9%

3. 51.6%

4. Misc

Explained :

1. 1800 + 150 + 2450 + 1300 + 300 = 6000

2. 2450/6000 = 0.409 = 40.9%

3. 1800 + 1300 = 3100 ; 3100/6000 = 0.516 = 51.6%

4. 300/6000 = 0.005 = 5%

To conserve water, many communities have developed water restrictions. The water utility charges a fee of $38, plus an additiona

earnstyle [38]

Using a linear function, the correct option regarding the situation is given by:

C) 57 ≤ 1.28x + 38 ≤ 87; To stay within the range, the usage should be between 14.8 and 38.3 HCF.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The bill is modeled by a linear function, with an <u>intercept of $38 and a slope of $1.28</u>, hence it is given by:

C(x) = 1.28x + 38

The bill should be between $57 and $87 dollars per month, hence:

57 <= C(x) <= 87.

The values of x are:

C(x) >= 57

1.28x + 38 >= 57

x >= 19/1.28

x >= 14.8.

C(x) >= 87

1.28x + 38 >= 87

x >= 49/1.28

x >= 38.3.

Hence option C is correct.

Trey believes there is a correlation between the number of texts sent during class and GPA. He collected data and found that the

vichka [17]

Answer: First Option

The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.

Step-by-step explanation:

The equation of a line has the following form

$y=mx+b$

Where m is the slope of the line and b is the intercept with the axis of the y

In this case, the equation is:

$y = 3.8 - 0.4x\\\\y=-0.4x+3.8$

Observe that

$m = -0.4\\b = 3.8$

So if x represents the number of texts sent during classes, this means that $x\geq 0$

When x increases by one unit then y decreases -0.4. For example when $x=1$ then $y=3.8-0.4=3.4$

Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.

The answer is the first option

A company wants to decrease their energy use by 17%. If their electric bill is currently $2500 a month, what will their bill be

expeople1 [14]

We need to find out how much 17 percent of 2,500 is, and then subtract that amount by 2,500. We can use proportions to use this. We can set up a fraction with x/2500 and another fraction with 17/100. Then, we need to cross multiply. This gives us 42,500. Next, we can divide by 100. This gives us 425. We know that they will save $425 if they decrease their energy use by 17%. We now need to subtract $425 from $2,500. This gives us $2,075. If the company is successful in decreasing their energy use by 17%, their bill would be $2,075.
