A restaurant owner wants to determine the effectiveness of his servers. the owner places a survey regarding the servers' effectiveness with randomly selected customer bills. what is the sample?

Answer:

y=-x+56

Step-by-step explanation:

A linear equation is an equation in which each term has at max one degree. The correct option is D, y = -x + 56.

A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

Given that the temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Therefore, an equation in slope intercept form to represent the temperature of the day at any given hour is,

y = 56 - x

y = -x + 56

Hence, the equation in slope intercept form to represent the temperature of the day at any given hour is y = -x + 56.

Answer:

3x² + 10x - 48

Step-by-step explanation:

Given

(x + 6)(3x - 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x - 8) + 6(3x - 8) ← distribute both parenthesis

= 3x² - 8x + 18x - 48 ← collect like terms

= 3x² + 10x - 48

Answer:

(2)  x =  a + (bc - bd)^2.

Step-by-step explanation:

√(x - a)/ b  + d = c

√(x - a)/ b  = c - d

√(x - a)   = bc - bd

Squaring both sides:

x - a =  (bc - bd)^2

x =  a + (bc - bd)^2

Answer:

51 meters

Step-by-step explanation:

Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?

We are to find the meters of fencing for the diagonal.

We solve the question using Pythagoras Theorem

= c² = a² + b²

Where

c = Diagonal

a = Width

b =Length

Diagonal² = Width² + Length ²

Hence:

Diagonal ² = 45² + 24²

Diagonal = √45² + 24²

Diagonal = √(2601)

Diagonal = 51 m

Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters

Answer:Mary' s dog should loose weight between  92%-95%

Step-by-step explanation:

Step 1

Mary's dog current  weight=  185 pound

weight to loose =Between  9 and 15 pounds

 Loosing 9 pounds , the dog"s new weight will be = 185- 9= 176 pounds

also

 Loosing 15 pounds , the dog"s new weight will be = 185- 15= 170pounds

Step 2

Percentage  of weight loss to current weight when he looses 9 pounds=

= 176/185 x 100

=0.95 x100=95%

Percentage  of weight loss to current weight when he looses 15 pounds=

= 170/185 x 100

=0.9189 x100

=91.89= 92%

Therefore Mary' s dog should loose weight between  92%-95%

If AB is 16, then AD is 8.

If AB = 12 and CB = 10, then the height of the triangle is 8.

Step-by-step explanation:

AD = [tex]\frac{AB}{2}[/tex], so AD is equal to 8.

Use the Pythagorean Theorem, [tex]\sqrt{10^{2} - 6^{2}}[/tex] equals 8, so the height of the triangle is equal to 8.

Answer:

25 years.

Step-by-step explanation:

Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:

5 x 5 = 25

25 + 15 = 40

40/2 = 20

5 + 15 = 20

Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

Answer:

2.4 miles per hour

Step-by-step explanation:

1/5 of a mile is 0.2 miles. If 0.2 miles is 5 minutes, then 0.04 miles is 1 minute, as you divide 0.2 by 5. 0.04 miles per minute=2.4 miles per hour as you times 0.04 by 60.

Answer:

They end up on the same vertical line. The length between them is 11 units if your looking on a graph.

Step-by-step explanation:

You can also answer this without a graph by looking at the x and y units for each pair. Since both points both have x as 0 you can know they will be on the same vertical line which for this question is zero. Then to find the length between each point just count up from -2. -2, -1, 0, 1 etc. That's the easiest way for my brain to comprehend it at least.

Answer:

anser A

Step-by-step explanation:

Let's fill x and y and we'll see which one is right

a) 0 = -3(-7+7)(-7+4)

<=> 0 = 3 * 0 * -3

<=> 0 = 0 => true

b) 0 = -0.5(-7-7)(-7+4)

<=> 0 = -0.5 * -14 * -3

<=> 0 =  -21 => false

c) 0 = (-7-7)(-7-4)

<=> 0 = -154 => false

d) 0 = 2(-7+7)(-7-4)

<=> 0 = 0 => true

so both a and d are right for (-7,0). Now let's for (-4,0)

a) 0 = -3(-4+7)(-4+4)

<=> 0 = 0 => true

d) 0 = 2(-4+7)(-4-4)

<=> 0 = -48 => false

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:

Given,

Two angles: X and [tex]\rm{X}+10[/tex]

As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.

There can be two possible outcomes:

Case 1. When the two equal angles are X

[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]

Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]

[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]

Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

The amount paid for different weights of oranges at a farmer's market are shown below (A) is the relationship between the price and the weight of the oranges proportional?

Oranges (lb) Price ($)

2--------- $3

3--------- $4.50

5--------- $7.50

Answer:

proportional relationship. Exist

Step-by-step explanation:

To check for propottionality:

2 = 3k

Solve for k = constant of proportionality

2/3 = 3k/3

2/3 = k

Quantity at price = 4.50

Price * k = quantity

4.50 * 2/3 = 3

Quantity at price = 7.50

Price * k = quantity

7.50 * 2/3 = 5

Hence, proportional relationship. Exist
