Answer:
11a) x=18
11b) 6x=108
11c) 4x=72
Step-by-step explanation:
11a) A line is equal to 180 degrees. Therefore, 6x and 4x have to add up to be 180.
6x+4x=180
10x=180
x=18
11b) We know what x is so we have to plug x into the expression. 6x=6(18)=108. 6x=108
11c) We know what x is so we have to plug x into the expression 4x=4(18)=72
4x=72.

on a line chart, you can change the of the vertical axis to provide more vertical space and a more dramatic slope to the lines.
we are allowed to change the vertical axis on a line chart.
why we need to change the vertical axis?suppose we have a large range of value needed to plot along the vertical and horizontal axis, but the current line chart cannot meet this demand. in such cases, we can customize the scales to provide more vertical and horizontal spaces.
what is dramatic slope?dramatic slopes are the steep slopes of a straight line calculated by vertical and horizontal coordinate of two points laying on it. By changing the vertical axis as well as the horizontal axis we can plot a graph of a straight line more properly and finally more dramatic slope is visible there.
hence, we can change the scale values on a line chart to meet the requirement of the plot.

A business rents in-line skates and bicycles to tourists on vacation. A pair of skates rents for $5 per day. A bicycle rents for $20 per day.
On a certain day, the owner of the business has 25 rentals and takes in $425.
Write a system of equation to represent this situation, then solve to find the number of each item rented.
Show both the equations and the solution.
Answer:
5x+20y=425
Step-by-step explanation:
Its 5 bucks for x pairs of skates
Its 20 dollars for y bikes
x+y rentals have to equal 25
all of this is equal to 425. All that is left to do is test with number until the statement is true.
try :

x + y do equal 25, and the total is equal to 425.
Determine if it is possible to form a triangle using the set of segments with the given measurements.
4.5 in., 5.6 in, 10 in.
a) No, adding all three sides does not add up to the correct measurements.
b) No, because two sides add up to less than the third one.
c) No, because two sides add up to more than the third one.
d) Yes, because two sides add up to less than the third one.
e) Yes, because two sides add up to more than the third one.
Answer:
e) Yes, because two sides add up to more than the third one.-------------------------
Apply the Triangle Inequality Theorem.
It states that:
For a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side.We'll take the sum of two shortest sides and compare with the longest:
4.5 + 5.6 = 10.1 > 10It confirms the theorem, without testing the other two sides (which is obvious) so the answer is yes.
The matching answer choice is e).

Let f(x,y,z)=(x^2)(y^3)+(z^3) and x=(s^2)*(t^3),y=s*t , and z=(s^2)*t .∂x/∂s=?
The value of ∂x/∂s is 4s^2 * t^6.
To find ∂x/∂s, we need to differentiate x with respect to s while treating t as a constant. Let's begin by substituting the given expressions for x, y, and z into the function f(x, y, z):
f(x, y, z) = (x^2)(y^3) + z^3
Substituting x, y, and z:
f(s, t) = ((s^2)(t^3))^2 * (s*t)^3 + ((s^2)*t)^3
Expanding the expression:
f(s, t) = (s^4 * t^6) * (s^3 * t^3) + (s^6 * t^3)
Now, let's differentiate x with respect to s:
∂x/∂s = ∂/∂s [(s^2)(t^3)]^2
Using the chain rule, we can differentiate each term separately:
∂x/∂s = 2 * (s^2 * t^3)^1 * ∂/∂s [(s^2)(t^3)]
Differentiating (s^2)(t^3) with respect to s:
∂/∂s [(s^2)(t^3)] = 2s * t^3
Substituting back into the expression for ∂x/∂s:
∂x/∂s = 2 * (s^2 * t^3)^1 * 2s * t^3
Simplifying:
∂x/∂s = 4s^2 * t^6
Therefore, ∂x/∂s = 4s^2 * t^6.

Explain why you cannot use the product of powers property to simplify (3z + y)^3. Be specific.
Any badd answer will be reported
The product of powers of exponents cannot be used to simplify the binomial expansion
Given data ,
Let the binomial expansion be represented as A
A = ( 3z + y )³
According to the property of products of powers, exponents can be multiplied when a power is increased to a higher power.
The product of powers characteristic cannot be applied to the equation (3z + y)³. This is due to the fact that (3z + y)³ is a binomial raised to the power of 3, not just a power of a single word.
These terms cannot be simplified further using the product of powers property because they involve different variables or variable combinations.

Given that V is finite dimensional and ϕ1,ϕ2,...,ϕn is a basis for V′=L(V,F) i.e. the dual of V. Show that there exists a basis of V whose dual basis is ϕ1,ϕ2,...,ϕn.
This shows that given a basis of linear functionals ϕ1,ϕ2,...,ϕn for the dual of V, there always exists a basis of V whose dual basis is ϕ1,ϕ2,...,ϕn.
Since V is finite dimensional, there exists a basis of vectors v1,v2,...,vn in V. By definition, the dual of V is a set of linear functionals ϕ1,ϕ2,...,ϕn such that ϕi(vi)=δij for all i,j=1,2,...,n. This means that the dual basis of V is ϕ1,ϕ2,...,ϕn. The basis of V can be expressed as a linear combination of the dual basis as follows: vi = ∑j=1n aijϕj for some constants aij. We can obtain the constants aij by evaluating both sides of the equation at vi: vi(vi) = ∑j=1n aijϕj(vi) = ∑j=1n aijδij = aii .Therefore, aii = vi(vi) for all i = 1,2,...,n. This implies that the basis of V whose dual basis is ϕ1,ϕ2,...,ϕn is given by: vi = vi(vi)ϕi for all i = 1,2,...,n. This shows that given a basis of linear functionals ϕ1,ϕ2,...,ϕn for the dual of V, there always exists a basis of V whose dual basis is ϕ1,ϕ2,...,ϕn.

The amusement park has two plans available for the school to choose from. Plan A is listed in the table below.
Cost (per vehicle) = $10
Cost (per person) = $30
The cost of Plan B can be calculated using the formula c = $15v + $28p, where c represents the cost, v represents the number of vehicles, and p represents the number of people. The school has a budget of $7200 for the cost of tickets and parking. If 241 students are going on the field trip, which plan should the school purchase? Explain your reasoning.
Answer:
the second plan should be purchased.
Step-by-step explanation:
school budget is $7200
plan 1: 241 students are $30 each is
241 × 30 = $7230 which is over budget with no money for parking for the vehicles.
plan 2: 241 students are $28 each is
241 × 28 = $6748
with a budget of $7200 for the trip the amount left for parking is
$7200 - $6748 = $452
plan 2: Parking is $15 per vehicle
Therefore the remaining $452 can be used to pay for 452 ÷ 15 = 30.13 vehicles
The school should purchase Plan 2 for the field trip.
The budget of $7200 can pay for 241 tickets for students and parking for 30 vehicles
The school should purchase the second plan.
School's budget = $7200
The cost for the first plan will be:
= 241 × $30
= $7230
This is more than the school budget of $7200
For the second plan, the cost will be:
= 241 × $28
= $6748.
This is below the school budget and therefore affordable.
The school should choose the second plan as there'll be more money available for parking.

Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
