`d=3t` represents the relationship between the distance `\left(d\right)`in inches that a snail is from a certain rock and the time `(t)` in minutes.



a. What does the number `3` represent? b. How many minutes does it take the snail to get `9` inches from the rock c. How far will the snail be from the rock after `9` minutes?

Answers

Answer:a.3 is the coefficient

b.3minutes

c.27inches

Step-by-step explanation:

a. In d=3t equation, d and t are variables. 3 is the coefficient for 't'.

b. In d=3t , d is 9inches.

so 9 = 3t

or t = 9/3 =3minutes

c. In d= 3t, t is 9minutes.

So d= 3*9 = 27inches.

Answer:

sorry I have no clue I don't like mathe either the half of the reason I can't answer it

The expression of length in terms of width is L = 10W and the length of the pan when the width is 7 feet will be 70 feet.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Suppose, the length and width of the pan are L and W corresponding.

As per the given,

(a)

The length of the pan was ten times its width.

L = 10W

The above expression is the length of the pan in terms of width.

(b)

The lasagna measured 7 feet wide.

L = 10 x 7 = 70 feet

Hence "According to the formula L = 10W, the length of the pan will be 70 feet when the width is 7 feet.".

D (Alicia did 5 more jumping jacks per minute than Melissa.)

Step-by-step explanation:

Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute.  To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

identify the slope and y-intercept of the function y = -2x+4

Answers

The y intercept is 0 because when you find x it’s 2 so you plug that in and you get y=0

Answer:

Slope = -2

y-intercept = (0, 4)

Step-by-step explanation:

The equation is written in slope-intercept form, y = mx + b, where "m = slope" and "b = y-intercept". Thus, we have to identify what part of the equation is part of each element in slope-intercept form:

Slope-intercept form

y = mx + b

Equation:

y = -2x + 4

m = -2

b = 4

Thus, the slope is -2 and the y-intercept is (0, 4)

Answers

The number of hours that Sam’s Soups is open on Sunday will be 14 hours.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Sam's Soups is open 6 days per week, 76 hours altogether. Its hours are similar consistently, besides on Saturday and Sunday. On those days, it is open 2 hours longer.

Let 'x' be the number of hours spent on Saturday and Sunday. Then the equation is given as,

x + x + (x - 2) + (x - 2) + (x - 2) + (x - 2) = 76

Simplify the equation, then we have

6x - 8 = 76

6x = 84

12,455 + x = 23,894

x = 10,560

Step-by-step explanation:

Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:

10,205 + x = 23,894

To solve, we must isolate the variable by subtracting 12,455 from both sides:

10,205 + x = 23,894

-10,205        -10,205

x = 10,560

So, the second month's salary was $10,560

Step-by-step explanation:

Answer: x = $30,560

Step-by-step explanation:

1. Let the second month payment be x

2. The first month + The second month = both of the months

3. So substituting: 10,205 + x = 40,765

4. Subtract 10,205 from both sides: x = 30,560

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

A chef made 150 cups of chili and sold 60% of it. Then the number of cups of chili that he sold will be calculated as,

⇒ 60% of 150

⇒ 0.60 x 150

⇒ 90 cups

The serving size of the chili is 1 ²/₃ cups.

Convert the mixed fraction number into a fraction number, then we have

1 ²/₃ cups = 1 + 2/3

1 ²/₃ cups = 5/3 cups

Then the number of servings of the chili sold will be calculated as,

⇒ 90 / (5/3)

⇒ 90 x (3 / 5)

⇒ 18 x 3

⇒ 54

The number of cups of chili that he sold will be will be 90 cups. Then the number of servings of the chili sold will be 54.

Mr. Chin asked his class to solve for y in the equation 8(3y - 5) = 9(y - 5) -1. Explain how to solve for y. Then solve.

Answers

Answer:

[tex]\Huge \boxed{\boxed{\bf{y = -\frac{2}{5} }}}[/tex]

Step-by-step explanation:

To solve for [tex]\tt{y}[/tex] in the equation [tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex], we'll need to simplify and isolate the variable.

Let's start by distributing the 8 on the left side and the 9 on the right side of the equation:

[tex]\tt{8(3y - 5) = 9(y - 5) - 1}[/tex][tex]\tt{24y - 40 = 9y - 45 - 1}[/tex]

Next, we'll combine like terms on both sides of the equation:

[tex]\tt{24y - 40 = 9y - 46}[/tex]

To isolate the variable, we'll move all the terms involving y to one side of the equation. Let's subtract 9y from both sides:

[tex]\tt{24y - 9y - 40 = 9y - 9y - 46}[/tex]

Simplifying further, we have:

[tex]\tt{15y - 40 = -46}[/tex]

To isolate "y," let's add 40 to both sides:

[tex]\tt{15y - 40 + 40 = -46 + 40}[/tex]

Simplifying, we get:

[tex]\tt{15y = -6}[/tex]

Finally, we can solve for "y" by dividing both sides of the equation by 15:

[tex]\tt{\frac{15y}{15} = \frac{-6}{15}}[/tex]

Simplifying the equation, we have:

[tex]\tt{y = -\frac{2}{5} }[/tex]

So, the solution to the equation is y = -2/5.

Friendly Medical Center's mission focuses on inpatient and outpatient rehabilitation of the severely injured and catastrophically ill. While the patient census aried from month to month, it appeared to the Friendly Medical Center Board of Trustees that the inpatient population was slowly but steadily declining. The hospital's market researchers reported that fewer people were being severely injured due to the popularity of seat belts and bicycle/motorcycle helmets. In order to get a handle on the future of the organization, the Board, and the CEO, Fred Splient M.D. called for a major strategic planning effort to take place. In January 20X6, Friendly Medical Center held a planning retreat to identify future opportunities. The outcome of the retreat was that the Medical Center needed to focus its fforts around two major strategic initiatives. The first, a short-run initiative, was to be more cost-effective in the delivery of inpatient care. The second, a long-run strategy, was to develop new programs and services that would capitalize on the existing, highly competent rehabilitation therapy staff and Friendly Medical Center excellent reputation in the region At the time of the retreat, Fred Splient's parents were living with him and his family. Fred was active member of the "sandwich generation." His parents were aging and developing many problems common to the geriatric populace. Their increased medical needs were beginning to wear on Fred and his family. It crossed Fred's mind that life might be more pleasant if the hospital Board approved an expansion of the Medical Center's campus to include living facility ssisted In March 20x6, Fred had his Business Development team prepare a rough estimate of the potential return on the investment of an assisted living facility. He asked the team to identify different options for facility construction and the associated costs. The team also did a complete competitive analysis and examined the options for services to be offered based on Friendly Medical Center's potential population base and catchment area. The Business Development team visited several facilities across the country. The team also interviewed companies that could oversee the design, building, and operation of the facility for Friendly Medical Center. The development team produced a preliminary business plan based on the recommended structure for the facility, estimated capital expenditure needs, estimated income from operation of the facility, as well as projected revenues to other Medical Center programs resulting from the facility's population. The plan was presented at the May 20X6 meeting of the Board of Trustees. Fred Splient and his team introduced the Board to the concept of opening an assisted living facility on Friendly Medical Center's campus. The facility would be set up as a for-profit subsidiary of the Medical Center so that it could generate a profit and not be subjected to the strict guidelines of the hospital's accrediting agencies. As a subsidiary organization, however, the Board would still have control The chosen facility design was a freestanding apartment-like facility with a sheltered connection to the Hospital for access to the kitchen and hospital services. The facility would have 100 units with 15 to 30 of the units classified as "heavy-assisted" and built to code to house the physically and medically disabled.
