Answer:

12

Step-by-step explanation:

let's say number of patches is x, and amount of time is y. the time per patch is k.

k * x = y

2 * k = 4

k = 2

2 * x = y

2 * 6 = 12

Answer:

0.1039

Step-by-step explanation:

Obtain the place value of 9 in each value and choose the smallest :

1.95

9 is the first digit after the decimal point ; which is equal to 0.9 = tenth place

0.1039

9 is the 4th digit after the decimal point ; which is equal to 0.0009 = ten thousandth place

3.092

9 is the second digit after the decimal point ; which is equal to 0.09 = hundredth place

2.009​

9 is the third digit after the decimal point ; which is equal to 0.009 = thousandth place

Hence the smallest value of 9 among the options given resides in 0.1039 (ten thousandth place).

Answer:

Please check the graph diagram attached.

From the diagram,

It is clear the parent function f(x) = x+8 has been translated down 5 units.

Step-by-step explanation:

The rule to determine the translating down 'b' units:

f(x) – b

It means if we have to translate a function f(x) 'b' units down, all we need is to subtract the 'b' units from the function output.

Given the function

f(x) = x + 8

In order to translate 5 units down, all we need is to subtract 5 units from the function.

i.e.

f(x) = x + 8 - 5

f(x) = x+3

Thus, we conclude that f(x) = x+3 is the translated function.

From the diagram,

It is clear the parent function f(x) = x+8 has been translated down 5 units.

The value of the given expression −(8 − 12) + 60 + (−4)² will be 80.

Arithmetic operators are operators in mathematics where basic four operators involve. Addition, multiplication, division, and subtraction.

Addition =  addition of two or more numbers or variable

For example =3 + 4

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example =8 - 9

Division = divide any two numbers or variable called division.

For example 7/3

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 4.

Given,

⇒  −(8 − 12) + 60 + (−4)²

⇒ -(-4) + 60 + 16

⇒ 4 + 60 + 16

⇒ 80

Hence "The value of the given expression −(8 − 12) + 60 + (−4)² will be 80".

Answer:

not 100% confident but I think this is at least close

Step-by-step explanation:

solve for one variable

1. x-5y=2

x=2+5y

plug this in to another equations and simplify

2. (2+5y)-y=16

2+4y=16

4y=14

y=3.5

this can be plugged in to all other equations to find x

1. x-5(3.5)=2

x-17.5=2

x=19.5

2. x-(3.5)=16

x=19.5

3. 2x-(3.5)=5

2x=8.5

x=4.25

4. x-3(3.5)=4

x-10.5=4

x=14.5

There are 5 bubble grid questions and 15 multiple choice questions.

Two or more expressions with an Equal sign is called as Equation.

Let,

Multiple choice questions denoted by M

Bubble grid questions are denoted by B

A 20-question math test is worth 100 points.

M+B=20..(1)

Multiple choice questions worth 4 points each. Bubble grid questions are worth 8 points each.

4M+8B=100..(2)

From equation 1,

M=20-B

4(20-B)+8B=100

80-4B+8B=100

80+4B=100

Subtract 80 from both sides

4B=20

Divide both sides by 4

B=5

Now plug in B value in equation 1.

M+5=20

Subtract 5 from both sides

M=15

Hence, there are 5 bubble grid questions and 15 multiple choice questions.

The required cumulative relative frequencies are 0.04, 0.44, 0.56, 0.80, and 1 respectively.  

The relative frequency of the data is the ratio of the given frequency to the total frequency in the observation.

From the given data,

Relative frequency = given frequency / total frequency

Where total frequency = 0.04 + 0.4 + 0.12 + 0.24 + 0.2 = 1

Value     Relative frequency       Cumulative frequency

3                 0.04/1 = 0.04                  0.04    

4                 0.4/1 = 0.4                    0.04 + 0.4 = 0.44  

5                    0.12                           0.44 + 0.12 = 0.56

6                   0.24                           0.56 + 0.24 = 0.80  

7                     0.2                            0.80 + 0.2 = 1

Thus the required cumulative relative frequencies are 0.04, 0.44, 0.56, 0.80, and 1 respectively.

[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]

Step-by-step explanation:

When given at least two points, you can find write an equation using the point-slope formula: [tex]y - y_1 = m (x - x_1)[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] are the x and y values from one point that need to be substituted in to make an equation, as well as the [tex]m[/tex] which represents the slope.

Find the slope by using the slope formula [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] and the two points given:

[tex]\frac{-1-0}{6-3}[/tex]

[tex]\frac{-1}{3}[/tex]

So, the slope is [tex]-\frac{1}{3}[/tex].

Next, choose a point (in this case, I chose (3,0)) and substitute its x and y values into [tex]x_1[/tex] and [tex]y_1[/tex] respectively, and also substitute  [tex]-\frac{1}{3}[/tex] for m. This forms an equation of a line in point-slope formula:

[tex]y - 0 = -\frac{1}{3} (x - 3)[/tex]
