[tex]l = 28 - 0.5d[/tex] is the required expression for the length of the bike

path left to build at any point during the construction.

[tex]l[/tex] is the  length of the bike path left to build at any point during the construction

[tex]d[/tex] is the number of days

What is Linear equation?

A one degree equation is called a linear equation.

Here,

Let the length of the bike path left to build at any point during the construction be [tex]l[/tex] and the number of days be [tex]d[/tex]

In one day, the crew build 0.5 miles of the path

In d days, the crew can build [tex]0.5 \times d[/tex] miles of the path

Length of path left to construct after [tex]d[/tex] days = [tex]28-0.5d[/tex]

By the problem,

                          [tex]l = 28 - 0.5d[/tex]

This is the required expression for the length of the bike

path left to build at any point during the construction.

Answer: C

Step-by-step explanation:

2x - y = 1

-2x         -2x

-y = -2x + 1

(-1) -y = -2x + 1 (1)

y = 2x-1

slope is positive 2/1, and the y-intercept is -1

The range is 4n - 12≤100.

The inequality is -3 + n≤25. From this, we can find the range of n.

n≤25 + 3

n≤28

Now we have to find the range of 4n - 12. For this, we have to ≤multiply both sides with 4 and then subtract it from 12, in the range of n.

That is;

4n≤ 28×4

4n - 12 ≤112 -12

4n - 12 ≤100

Therefore the range is 4n - 12≤ 100.

The distance between in two cities is 360 miles.

Given,

It took a plane 2 hours to fly from Dallas to New York

The headwind and 1.5 hours to return with the tailwind.

and, the speed of the wind was 30 mph.

To find the how far apart are the two cities?

Now, According to the question:

Let speed of be x

Speed of wind be c

Also note D = RT, where

D is distance and R is rate and T is time

For First Leg:

we can write:

(x - c) × 2 = D

2x - 2c = D

For Second Leg:

we can write:

(x+ c) × 1.5 = D

1.5x + 1.5c = D

We can equate and write:

2x - 2c = 1.5x + 1.5c

0.5x = 3.5c

We know Speed of Wind, c, is 30, so we have:

0.5x = 3.5(30)

0.5x = 105

x = 105/0.5 = 210 [speed of airplane]

We know distance is

D = 2x - 2c

D = 2(210) - 2(30)

D = 420 - 60

D = 360 miles

Hence, The distance between in two cities is 360 miles.

Each cow receives seven pounds of cow chow from Bob. Every time he feeds, farmer Bob uses at least 84 pounds of cow chow, which means that each time he feeds, 12 cows in total.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Cow chow fed to each cow by the farmer =7 pounds

Total cow chow used by the farmer to feed the cows every time = 84 pounds

Total cow chow used = no. of cows *cow chow fed to each cow

No. of cows = Total cow chow / cow chow fed to each cow

                    = 84/7

                    =12

No. of cows = 12

Therefore, 84 pounds of cow chow is used to feed 12 cows each time.

Clare plans to fold up the sides of a poster board that is 30 inches by 25 inches of box. The volume V(x)=4x³-110x²+750x.

Given that,

Clare plans to fold up the sides of a poster board that is 30 inches by 25 inches and trim the corners to create an open-top box. The open-top box's volume, "V(x)," in cubic inches, depends on the square cuts' side length, "x," in inches.

Length =30 inch

Width=25 inch

The box's size changes when x is taken out of the container.

Length=30-2x

Width=25-2x

Height=x

Because x is eliminated from both ends, we subtract 2x.

The volume is then determined as follows:

V(x)=length×width×height

V(x)=(30-2x)×(25-2x)×x

V(x)=(30-2x)×(25x-2x²)

V(x)=750x-110x²+4x³

V(x)=4x³-110x²+750x

Therefore, the volume V(x)=4x³-110x²+750x.

We know,

Total peanuts already in the mixture = 18 x [tex]\frac{62}{100}[/tex] = 11.16 kg

The  new mixture contains 52% peanuts, then, [tex]\frac{x_{peanuts} }{x_{total} }[/tex] = 0.52.

Furthermore, 40% must be added.

[tex]x_{peanuts}[/tex] = [tex]0.4x[/tex] + [tex]11.16[/tex]

This gives us the following equation,

[tex]\frac{0.4x + 11.16}{18 + x } = 0.52[/tex]

⇒ [tex]0.52 x +[/tex] 0.52 x 18 = [tex]0.4x + 11.16[/tex]

Inverse function of expression is [tex]\frac{1}{2}[/tex]x + 2.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f1.

In the broadest sense, inverse functions are functions that "reverse" one another. The inverse, f 1 f-1 f1f, start superscript, minus, 1, end superscript, must take b to a, for instance, if f takes a to b.
