How do equations or inequalities help us understand how to interpret whether a solution is possible for a particular real world situation

Answers

Answer 1
If you simplify a polynomial equation and then try to solve each side for 0 and come
Up with an imposible solution to one of the sides, then it tells us that that particular number cannot be used to get satisfy the equation. One real life application of inequalities is in profit maximizing. We use inequality equations to determine which product/production combination should be used in order to generate the most profit

guys i need huge help. this isn’t a “brainly” question but i do my work online, and i have over 150 OVERDUE assignments. i’ve been doing them but it’s so so so hard to catch up and REPORT CARDS come out on tuesday. if i don’t have my work completed by then i’ll have all “f’s” HELP ME how can i catch up? any advice? :(

Answers

Answer:

Step-by-step explanation:

oh my 150 overdue

you should start with one subject and finish them up. then move on to the next subject. dont switch subjects and focus. youll get them all sooner if you pay attention. dont cheat!

Answer:

ok, so i feel you. i don't have 150 overdue but i do have 13 lol. so today is wednesday, so you have 6 days. 150÷6=25. so try to do 25 assignments a day. i know it feels sooooo stressful, but i mean you have to make up for all those days you didn't do work. make a list of everything you have to do (on paper or in google docs/notes/word). don't do work in your bed; it makes you feel lazy. do it at a table or desk. clean your work area! have a piece of paper and a pencil so you can work out problems. fill up a glass of water right next to you. play some chill music; NOT your favorite songs! they will distract you! ask your alexa/google home/apple homepod to play some study music, or play it from your phone or whatever. just some background music to help you focus. if you play music from your phone, make sure to keep it on silent and do not disturb so you don't get distracted by notifications. work alone, not in a room with other people. just power through your work. take it one at a time; don't overwork yourself. take breaks if you need to, but don't get too distracted. after you complete your 150 assignments, try to work ahead so this never happens again.

Step-by-step explanation:

if you need more help, of course use brainly or quizlet or essay typer. but try not to cheat most of the time; it'll make you feel more proud if you don't.  i really hope this helps you. i know you can do it. i wish you the best of luck! <3

So 5 times 6 is 30

Don’t forget the unit, which in this case is inches, and anytime you have area, you have to have a squared, or an exponent 2

For a school art project, Kali has 604 square tiles measuring 1 inch on each side. She plans to use the tiles to completely cover the box in the shape of a rectangular prism shown below. (FORMULA: Surface Area = 2lw + 2lh + 2wh) Which statement about Kali's tiles is true? Group of answer choices Kali needs 476 more tiles to completely cover the box. Kali needs 104 more tiles to completely cover the box. Kali will have 534 tiles left after completely covering the box. Kali will have 250 tiles left after comp

Answers

Answer:

Kali needs 104 more tiles to completely cover the box.

Step-by-step explanation:

Length of box =  20 in

Breadth of box = 6 in

Height of box= 9 in

Total surface area of box = 2lw + 2lh + 2wh

Total surface area of box = 2(20)(6) + 2(20)(9) + 2(6)(9)

Total surface area of box = 708 sq. in.

Side of tile = 1 in

Area of 1 tile = [tex]Side^2 = 1^2 = 1 sq. in[/tex]

Area of 604 tiles = 604 sq. in.

Area remain uncovered = 708 - 604 = 104 sq.in.

So, Kali needs 104 more tiles to completely cover the box.

Write a linear function f with f(0)=3 and f(−6)=3

Answers

Answer:

y = 3

Step-by-step explanation:

Slope = 0/-6 = 0

y-int. = 3

The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].

Given two distinct points on cartesian plane, we can determine the linear function associated to those points as follows:

[tex]y = m\cdot x + b[/tex] (1)

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)

[tex]b = y_{1}-m\cdot x_{1}[/tex] (3)

If we know that [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex], then we have the linear function below:

[tex]m = \frac{3-3}{0-(-6)}[/tex]

[tex]m = 0[/tex]

[tex]b = 3 - 0\cdot (0)[/tex]

[tex]b = 3[/tex]

The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].

7) Cameron wants to buy new lacrosse equipment that costs $55.25. She plans to save $4.25 each
week. Write and solve an equation to determine how many weeks it will take her to save enough
money to buy the equipment. Define your variable and label your answer!

Answers

Answer:

13 weeks

Step-by-step explanation:

Let's say the number of weeks she will take is x. This would mean that 4.25 times the number of weeks(x) is equal to 55.25

Equation:

4.25x = 55.25

x=13

A dairy cow can produce up to 2,000 gallons of milk every 365 days. At this rate, a cow can produce x gallons of milk in 500 days. Which proportion should be used to find x

Answers

So if the cow can produce 2000 gallons of milk in 365 days, how many gallons can she produce in 1 day?
We find this by dividing 2000 by 365:

2000/365 = 5.4794 gallons of milk per day

Now, to find the amount of gallons she produces in 500 days, we simply multiply the number of gallons she produces in 1 day by 500:

5.4794 X 500 = 2,739.73 gallons in 500 days.

Town M is 282 feet below sea level. Town R is 679 feet above sea level. How much higher, in feet, is Town R than Town M?​

Taylor bought a necklace for each of her three sisters. She paid $7.50 for each necklace. Supposed she had $9 left. How much money did she have initially to spend on each sister?

Answers

Answer:

7.50 x 3= 22.50

22.50+9= 31.50

Step-by-step explanation:

If each necklace was $7.50 and she got one for each of her 3 sisters then we need to multiply $7.50 by 3. Finally, she has $9 left over. So if we add the total she spent on the necklaces and the 9 she has left over then we will get the total she started with.

I’m pretty sure it’d would be the first car because when dividing the miles by the hours they travelled you get how many miles they drove per hour so try the first car.

Since this is a downward opening parabola, it won't have a lower boundary, which means that the answer must be (negative infinity, 4]

We can further check that's correct by seeing that the parabola has its vertex at 4, which is written in the answer.

Two hikers walk on a trail in the direction of increasing mile marker numbers. Mandy starts at mile marker 1 and hikes at a rate of 2.5 miles per hour. At the same time, Rita starts at mile marker 2 and hikes at a rate of 3 miles per hour. The equation 2.5h+1=3h+2 represents the number of hours h it will take Mandy to catch up with Rita.

Answers

Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.

Given:

The number of hours h it will take Mandy to catch up with Rita is represented by the equation

[tex]2.5h+1=3h+2[/tex]

To find:

The value of h.

Solution:

We have,

[tex]2.5h+1=3h+2[/tex]

Isolate the variable terms on one side.

[tex]2.5h-3h=-1+2[/tex]

[tex]-0.5h=1[/tex]

Divide both sides by -0.5.

[tex]h=\dfrac{1}{-0.5}[/tex]

[tex]h=-2[/tex]

We know that, time cannot be negative. So, [tex]h\neq -2[/tex].

The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.

Therefore, Mandy will never catch up with Rita.
