What is the slope of the line?

27y = 3x - 54

Answers

Answer 1
First you need to simplify it:
27y=3x-54
9y=x-18
Now divide everything by 9
y=1/9x-18/9
y=1/9x - 2 

This means that the slope is 1/9

Hope this helps :)

Answers

-1/5 is the answer because I have had this question before and I got it right


Answer:  -9

Step-by-step explanation: Distribute: 2x - 6 + 1= 3x + 4. Combine like terms on the left side: 2x - 5 = 3x + 4. Subtract 2x from both sides: -5 = x + 4. Subtract 4 from both sides: x = -9.

Sales Tax is percent
a)increase
b)decrease
Discount is percent
a)increase
b)decrease
Tip is percent
a)increase
b)decrease

Answers

Sales Tax would be considered a) percent increase, because it is an added amount onto the total. Discount would be considered b) percent decrease, because it takes a certain amount off of your total. Tip would be considered a) percent increase, because similar to sales tax, you must add it on to your total.
The Sales Tax is percent: Increase because it is going upward and you're adding on 

Discount is percent:  Decrease because it is downward and because you're taking a certain amount off 

Tip  is percent : Increase because you're giving  in and it kind of like the "Sales Tax" 

Therefore, your answers would have to be: Increase,Decrease, and Increase :)

(1) The three salespeople for a local advertising firm are Lola, Ahmed, and Tommy. Lola sold $2030 in ads, Ahmed sold $1540, and Tommy sold $1800. (a) What fraction of the total sales did each salesperson sell? (b) A $100 bonus was awarded to the three salespeople, which they had to share. It was awarded so that each salesperson received the same fraction of $100 as he or she sold of the total sales. How much did each person receive? Round to the nearest whole cent.

Answers

Answer: a) Fraction of the total sales did each salesperson sell:-

[tex]\text{Lola}=\frac{203}{537}[/tex]

[tex]\text{Ahmed}=\frac{154}{537}[/tex]

[tex]\text{Tommy}=\frac{180}{537}[/tex]

b) Each person receive=$33

Step-by-step explanation:

Given: The three salespeople for a local advertising firm are Lola, Ahmed, and Tommy.

Sales by Lola= $2030

Sales by Ahmed=$1540

Sales by Tommy=$1800

Thus, the total sales= $2030+$1540+$1800=$5370

Fraction of the total sales did each salesperson sell:-

[tex]\text{Lola}=\frac{\text{Sales by Lola}}{\text{total sales}}=\frac{2030}{5370}=\frac{203}{537}[/tex]

[tex]\text{Ahmed}=\frac{\text{Sales by Ahmed}}{\text{total sales}}=\frac{1540}{5370}=\frac{154}{537}[/tex]

[tex]\text{Tommy}=\frac{\text{Sales by Tommy}}{\text{total sales}}=\frac{1800}{5370}=\frac{180}{537}[/tex]

If $100 bonus was awarded to the three salespeople, then

Each person receive=[tex]\frac{\$100}{3}=33.33\approx\$33[/tex]


which parachute has a slower descent: a red parachute that falls 10 feet in 4 seconds or a blue parachute that falls 12 feet in 6 seconds?

Answers

blue because it travels longer faster

Well 10/4 is 2.5
So the red parachute will fall at 2.5 m/s.

And 12/6 is 2
So the blue parachute will fall at 2 m/s.

Meaning the blue parachute has a quicker descent.

bailey can hit 42 golf balls in 3 1/2 hours. if she hits golf balls at a constant rate,

Answers

If Bailey can hit 42 golf balls in 3 1/2 hours, that is a fraction. 42 golf balls per 3 1/2 hours:
42 golf balls
3 1/2 hours
You want to make this number so it is how many golf balls per 1 hour(x is the number of golf balls:
x golf balls
1 hour
To get this number you would divide the numerator(the number on top), by the denominator(the number on the bottom). You would get 12 golf balls per hour.
12 golf balls
1 hour

Bayley can hit a single golf ball every 5 minutes

Now Bayley can hit 42 golf balls in 3 1/2 hours

Thus converting the 3 1/2 hours in minutes:

3 hours +  1/2 hours = 180 minutes + 30 minutes = 210 minutes

Bayley can hit 42 golf balls in 210 minutes

Thus let's say she takes 'x' minutes to hit one ball

Calculating the value of 'x'  using direct proportion theorem:

[tex]\frac{x}{210}=\frac{1}{42}[/tex]

[tex]x*42 = 210[/tex]

[tex]x= \frac{210}{42}[/tex]

[tex]x = 5[/tex]

Thus Bayley can hit 5 golf balls every 1 minute

A sofa is on sale for
$442, which is
35% less than the regular price.
What is the regular price?

Answers

the regular price of the sofa is $684.61.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, A sofa is on sale for $442, which is 35% less than the regular price.

Thus,

65% of the regular price  = 442

The regular price = 445*100/65

Thus, Regular price =  $684.61

Therefore, the regular price of the sofa is $684.61.

a square rug has an area 80ft which is the best approximation of the length of one side of the rug.....Explain...If you can show work

A ) 6.4ft
B ) 7.5ft
C ) 8.9ft
D ) 20ft

Answers

So to find the answer, first we need to understand how to approximate square roots. 80 is an imperfect square, so we're going to have to round the answer. To find that, we need to find the multiples 80.

72, 80, 81.
8, x, 9

So the distance apart between 72 and 81 is 9. The answer, x, is obviously between 8 and 9, and since the distance between these to is 9, your answer is going to be 8.9 .
Final answer:

The length of one side of the square rug is found by taking the square root of the area of the rug, which is 80 square feet. The best approximation for this is 8.9 feet.

Explanation:

This problem is about understanding the relationship between the area and the length of a side in a square. In a square, all sides are equal in length, and the area of a square is given by the equation Area = side*side. So, if the area is given, we can find the length of a side by taking the square root of the area.

Here, since the area of the square rug is 80 square ft., we find the length of one side by calculating the square root of 80. The square root of 80 is approximately 8.9ft

So, looking at the options given, the best approximation for the length of one side of the rug is option C) 8.9ft.

identify the independent and dependent variables in the following y=4x+1

Answers

Final answer:

In the given equation y=4x+1, the independent variable is x, and the dependent variable is y. The independent variable is the cause, and the dependent variable is the effect. Therefore, any change in x will result in a change in y.

Explanation:

In the given equation y=4x+1, the independent variable is x and the dependent variable is y. This is because the value of x is not dependent on any other variable, while the value of y depends on x. The variable y is dependent because it changes in response to the value of x.

Conceptually, the independent variable is what you have control over or manipulate, and the dependent variable is what you observe or measure. For example, in the equation y = a + bx, a is the y-intercept, b is the slope, x is the independent variable, while y is the dependent variable that changes according to the value of x.

Simply put, the independent variable is the cause, and the dependent variable is the effect. In the context of this equation, any change in x (independent variable) will cause a change in y (dependent variable).
