An absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45

We are told that a can of soda can have a minimum of 35 milligrams of sodium and a maximum of 45 milligrams of sodium.

Now, an absolute value inequality that represents this expression would be written as;

35 ≤ A ≤ 45

Thus, we conclude that an absolute value inequality that represents the acceptable amounts of sodium is; 35 ≤ A ≤ 45

When he walked a constant 4 miles per hour on the level road, 3 mph on uphill and 6 mph on downhill, then he walked 20 miles

Given,

A man walked for five hours

First he walked along a level road, then up a hill, then he returned around and walked back to his starting place along the same route.

We know,

Speed = Distance/ Time

Time = Distance / Speed

The speed when he walked on the level road = 4 miles per hour

Distance traveled on the level road = A

Time taken = [tex]\frac{A}{4}[/tex]

The speed when he walked on uphill = 3 miles per hour

Distance traveled on the level road = B

Time taken = [tex]\frac{B}{3}[/tex]

The speed when he walked on downhill = 6 miles per hour

Time taken = [tex]\frac{B}{6}[/tex]

Then he walked level road again

Total time taken = Time taken on level road+ Time taken on uphill+ Time taken on downhill+ Time taken on level road

[tex]\frac{A}{4}+\frac{B}{3}+\frac{B}{6}+\frac{A}{4}=5\\ \frac{3A+4B+2B+3A}{12}=5\\[/tex]

6A+6B=60

2A+2B=20

Hence,  when he walked a constant 4 miles per hour on the level road, 3 mph on uphill and 6 mph on downhill, then he walked 20 miles

The simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also the function for the maximum and minimum weight is y + x and y - x

Here,

Given that, A package with a labeled weight of 9.4 pounds can have an actual weight plus or minus 0.22 pounds.
Let the weight labeled be y and the actual weight be x
Weight = y ± x
Maximum weight = y + x
Minimum weight = y - x

Weight = 9.4 ± 0.22
Now,
Maximum weight = 9.4 + 0.22 = 9.62 pounds
Minimum weight = 9.4 - 0.22 = 9.18 pounds

Thus, the simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also, the function for the maximum and minimum weight is y + x and y - x

the volume of the cone when radius is cm  and height is 13 cm is 340.34 cm³

What are derived units?

Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the International System of Units (SI). There are two types of derived units: dimensionless and the product of base units.

Here, the given data for cone are :

radius of base r = 5 cm = 0.05 m

height of cone h = 13 cm = 0.13 m

Now, the volume V of cone is given by :

V = 1/3 πr²h

Now, finding the volume of cone by substituting the values in above equation :

V = 1/3 πr²h

V = 1/3  π x (5)² x 13

V = 340.34 cm³

Therefore, the volume of the cone is 340.34 cm³

Cost of Kersey and Jeana is reported. x=6 that is when they each purchase a sweater and six pairs of pants.

Given that,

Kelsey spends $24 on a pullover and $17.95 each on numerous pairs of uniform pants. At a different store, Jeana purchases a sweater for $18 and several pairs of uniform pants for $18.95 apiece.

Cost for Kersey is reportedly;

$17.95 per pair of pants

$24 for each sweater

If there are x pants.

The overall price for Kersey is then;

17.95x + 24

Cost for Jeana, we are informed, is;

$18.95 for each pair of pants

Sweater price: $18

If there are x pairs of pants.

Therefore, Jeana's overall cost is;

18.95x + 18

In the following circumstances, their overall cost will be equal:

17.95x + 24 = 18.95x + 18

18.95x - 17.95x = 24 - 18

x = 6

Therefore, x=6 that is when they each purchase a sweater and six pairs of pants.

The dimensions of the rectangle =  6 ft

Along with arithmetic, geometry is among the oldest subfields of mathematics. It is concerned with spatial characteristics like the separation between objects, their shape and size, and their relative positions. Geometer is the term used to describe a mathematician who specializes in geometry.

At a fundamental level, geometry is essential to understand because it lays the groundwork for learning more complex mathematical concepts. Raj Valli, the founder of Thinkster Math, notes that algebra and geometry frequently overlap. In science and math classes, it introduces crucial formulas like the Pythagorean theorem.

length = 2w - 1

We know that the area:

Area = length * width

Area = 2w - 1 * width

A= 2w^2 -w = 21

2w^2 - w -21 = 0.  Solve for w using quadratic formula.  

[-b±√(b2 - 4ac)]/2a

[1± √((-1)^2 - 4*2*(-21))]/(2*2)

[1± √(1+168)]/4

w = 3.5 ft

length = 2w - 1

= 2*3.5 - 1

= 6 ft

Answer:

No solutions.

Step-by-step explanation:

We are given the inequality 6(x+3) < 3(2x+6), and we want to solve the inequality for x.

We can first do the distributive property on both sides, where we multiply each term on the left side by 6, and each term on the right by 3.

6(x+3) < 3(2x+6)

6x + 18 < 6x + 18

Solving inequalities is a lot like solving equations; we want to isolate the variable by itself on one side.

First, we can subtract 18 from both sides.

6x + 18 < 6x + 18

    -18           -18

____________________

6x < 6x

Now, we can subtract 6x from both sides, to get 6x off the right side.

6x < 6x

-6x   -6x

0 < 0

We now have the inequality 0 < 0. This is never true, as 0 is always equal to 0.

Therefore, there are no values of x that will make this true, because no matter what, we will end up with a false statement. The answer is no solutions.

When x = 25, y = 125, meaning that the monthly home heating bill was of $125 for a month with average temperature was of 25ºF.

From the points in the scatter plot, when x increases, y decreases, which is the answer for the second item of the question. It makes sense, as when it is hotter, the spending in heaters is unnecessary.

The probability is 0.1932 that a randomly selected man considers himself a professional fan.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given data as:

The number of randomly selected men, n = 10.

Probability of success, that a randomly selected man considers himself a professional fan, p = 61% or 0.61

Probability of failure, that a randomly selected man does not consider himself a professional fan is:

⇒ q = 1 − p = 1 − 0.61= 0.39

The probability that the number of men who consider themselves professional fans is:

⇒ ⁿcₓpˣqⁿ⁻ˣ

Substitute exactly x = 5

⇒ ¹⁰c₅(0.61)⁵(0.39)¹⁰⁻⁵

⇒ ¹⁰c₅(0.61)⁵(0.39)⁵
