Step-by-step explanation:
A truck driver is driving on an interstate and is about 150 miles from his planned exit. He is traveling at a speed of 50 miles per hour and plans to stop for a rest within 30 miles of the exit on either side. Find the minimum and maximum numbers of hours the truck driver will drive before stoping for a rest.
The minimum and maximum numbers of hours the truck driver will drive before stoping for a rest will be 3.6 hours and 2.4 hours respectively.
How to illustrate the information?From the information, the truck driver is driving on an interstate and is about 150 miles from his planned exit and he is traveling at a speed of 50 miles per hour and plans to stop for a rest within 30 miles of the exit on either side.
Therefore, the appropriate equation be:
50h - 150 = 30
50h = 30 + 150
50h = 180
Divide
h = 180 / 50
h = 3.6 hours.
The minimum hours will be:
50h = 150 - 30
50h = 120
h = 120/50
h = 2.4 hours.

If α =i+j−2k, β =−i+2j+3k andγ =5i+8k, then find c and d such that γ−cα−dβ is perpendicular to both α and β
If [tex]\hat\gamma-c\hat\alpha-d\hat\beta[/tex] is perpendicular to both [tex]\hat\alpha[/tex] and [tex]\hat\beta[/tex], then their dot products are zero.
Recall that for any vector [tex]\hat x[/tex], [tex]\hat x\cdot \hat x = \|\hat x\|^2[/tex].
Now, we have
[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\alpha = (\hat\gamma\cdot\hat\alpha) - c\|\hat\alpha\|^2 - d (\hat\beta\cdot\hat\alpha) = 0[/tex]
[tex]\hat\gamma\cdot\hat\alpha = 5 + 0 - 16 = -11[/tex]
[tex]\|\hat\alpha\|^2 = 1^2 + 1^2 + (-2)^2 = 6[/tex]
[tex]\hat\beta\cdot\hat\alpha = -1 + 2 - 6 = -5[/tex]
[tex]\implies 6c - 5d = -11[/tex]
and
[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\beta = (\hat\gamma\cdot\hat\beta) - c(\hat\alpha\cdot\hat\beta) - d \|\hat\beta\|^2 = 0[/tex]
[tex]\hat\gamma\cdot\hat\beta = -5 + 0 + 24 = 19[/tex]
[tex]\|\hat\beta\|^2 = (-1)^2 + 2^2 + 3^2 = 14[/tex]

Solve for [tex]c[/tex] and [tex]d[/tex]. By elimination,
[tex]5(6c - 5d) - 6(5c - 14d) = 5(-11) - 6(-19)[/tex]

over the period every year Julie‘s net worth increased which of the following could be true
(D) Julie's assets decreased by more than her liabilities: TRUE
What are assets?An asset is any resource owned or controlled by a business or economic entity in financial accounting. It is anything that has the potential to generate positive economic value. Assets are ownership values that can be converted into cash. Physical assets include machinery, property, raw materials, and inventory, as well as intangible assets such as patents, royalties, and other intellectual property.So, assets are simply the resources that a person or company possesses, whereas liabilities are the debts that the economic agent owes to others.
Juliet's net worth will decrease because the value of her debt increased faster than the rate at which her assets increased. Julie's assets decreased more than her liabilities in this case.Therefore, the statement "(D) Julie's assets decreased by more than her liabilities" is TRUE.

Teresa has a total of 13 coins.
None of them are pennies, and she has at least three each of quarters, dimes, and nickels.
What is the least amount of money she can have?
Answer: $0.65
Step-by-step explanation:
She can have all nickels since at least 3 nickels means that there is a possibility that all 13 of her coins are nickels.
100 cents=1 dollar
Nickel=5 cents
5 cents * 1 dollar/100 cents=
5*1/100=0.05 dollars
Hence, the least total amount of money she could have is:
13*0.05=$0.65
This is equivalent to 140 cents.
==========================================================
Explanation:
"she has at least three each of quarters, dimes, and nickels"
Let's say she has exactly 3 of each for now
3 quarters = 3*25 = 75 cents3 dimes = 3*10 = 30 cents3 nickels = 3*5 = 15 centsSo far she has 75+30+15 = 120 cents (aka $1.20) with the 3*3 = 9 coins mentioned. There are 13-9 = 4 coins remaining
To achieve the least money possible, those missing four coins must be the smallest denomination allowed, i.e. the nickel. We can't go for penny since it states "none of them are pennies". So we add 4*5 = 20 more cents onto 120 to get 120+20 = 140 cents aka $1.40
True or false is zero is subtracted from an integer the result is the integer

The length of a rectangel is 11 less than 9 times the width. The perimeter of the rectangle is 18 inches
According to the question, the given parameters has relationship between the length and the width of the rectangle.
The perimeter of the rectangle is 18 inches.
Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:
Let us assume, the width of the rectangle be 'w' inches
The length of a rectangle be (9w - 11)
As we know, perimeter of a rectangle is 2(l + w)
Substitute the calculated parameters in the perimeter formula:
18 = 2(9w - 11 + w)
⇒ 9 + 11 =10w
⇒ w = 2 inches and l = 7 inches
Then, the calculated width is 2 inches and length is 7 inches.

Determin whether the relation defines a function, and give the domain and range.
The relation is not a function if its domain is on the x-axis and its range is on the y-axis. However, if the relation's domain is on the y-axis and its range is on the x-axis, it is a function.
If so, what kind of function is it?
Relationships are defined by three factors:
1. domain is a set of inputs.
2. an output set referred to as range.
3 . relationships between domain and range-related items.
If and only if each element of the domain is associated to just one member of the range, is a relation a function. It must be noted that the solution may vary based on the domain and range that we assume.
The provided relation is a function if the x-axis is the range and the y-axis is the domain, as opposed to when the x-axis is the domain and the y-axis is the range.

Identify the angle relationship and find the measure of the indicated angle.
(Alternate Interior, Alternate Exterior, Corresponding, Same-side Interior)
The angled relationship is the Same-side interior angle where x is 6 and ∠EFG is 102°
For the parallel lines ED and FG, where EF is the transversal,
The angle DEF and the angle EFG are same-side interior angles.
By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).
∠DEF = 13x°
∠EFG = 17x°
∠DEF + ∠EFG = 180°
13x + 17x = 180
30x = 180
x = 6
∠DEF = 13x = 13*6 = 78°
∠EFG = 17x = 17*6 = 102°
Therefore, the angles follow the same-side interior angles relationship, x = 6 and ∠EFG = 102°
