A car rental company offers two plans for renting a car. Plan A: $30 per day and $0.18 per mile Plan B: $50 per day with free unlimited mileage How many miles would you need to drive for plan B to save you money?
Answer:
For plan B to save money car rental need to drive 111.1 miles as [tex]\frac{x}{y}[/tex] expresses the average amounts of miles per day car rental drive and its obtained value is 111.1.
Step-by-step explanation:
In the question it is given that a car rental company offers two plans for renting a car.
Plan A: $30 per day and [tex]$\$ 0 \cdot 18$[/tex] per mile.
Plan B: $50 per day with free unlimited mileage
It is required to find that how many miles would be needed to drive for plan B to save money. be needed to drive for plan B to save money.
Step 1 of 5
In Plan A $30 per day and [tex]$\$ 0 \cdot 18$[/tex] per mile are costed so the cost of Plan A is given by following equation,
[tex]$$A=30 y+0 \cdot 18 x$$[/tex]
In Plan B $50 per day with free unlimited mileage are costed so the cost of Plan B is given by following equation,
[tex]$$B=50 y$$[/tex]
Step 2 of 5
Now comparing the obtained equations [tex]$A=30 y+0 \cdot 18 x$[/tex]
and B=50y.
[tex]$$30 y+0 \cdot 18 x=50 y$$[/tex]
Step 3 of 5
Subtract 30y from both the sides of the obtained equation 30 y+0.18x=50y and simplify using subtraction properties.
[tex]$$30 y+0 \cdot 18 x-30 y=50 y-30 y$$\\ $0 \cdot 18 x=20 y$[/tex]
Step 4 of 5
Divide both the sides of the obtained equation [tex]$0 \cdot 18 x=20 y$[/tex] by [tex]$0 \cdot 18$[/tex] and simplify using division properties.
[tex]$$\begin{aligned}&\frac{0 \cdot 18 x}{0 \cdot 18}=\frac{20 y}{0.18} \\&x=\frac{1000 y}{9}\end{aligned}$$[/tex]
Step 5 of 5 save money car rental need to drive 111.1 miles.
[tex]$$\begin{aligned}&\frac{x}{y}=\frac{1000 y}{9 y} \\&\frac{x}{y}=111.1\end{aligned}$$[/tex]

The product of two consecutive positive integers is 194 more than the next integer. What is the largest of the three integers?
Answer:
16
Step-by-step explanation:
let x be a positive integer
mathematically, the statement: “The product of two consecutive positive integers is 194 more than the next integer” means x(x + 1) - 194 = x + 2
………………………………
Solving the equation x(x + 1) - 194 = x + 2 for x :
x(x + 1) - 194 = x + 2
⇔ x² + x - 194 = x + 2
⇔ x² - 194 = 2
⇔ x² = 196
⇔ x = 14 or x = -14
Since -14 < 0 then the solution to our equation is x = 14
Therefore
The largest integer of the three is x + 2 = 14 + 2 = 16
Verification:
14 × 15 − 194 = 210 − 194 = 16

Using a significance level of 5%, the appropriate conclusion for a test with a p-value of 0.0421 would be:
A significance level of 5% (more commonly referred to as 95%) corresponds to a statement that (only) a probability of 5% or less is that a particular randomly generated observation is accepted as significant.
In this example, the p-level (the true probability that the observations are randomly generated) is less than 5% (0.0421 <0.05), so we can draw the conclusion that the observations are significant.
p = 0.0421 means that the probability is only 0421/1000. The choice of significance level to reject the null hypothesis is optional. Traditionally, 5%, 1%, and 0.1% levels have been used. In rare situations, a 10% significance level is also used.

A table representing the function f(x) = 2(three-halves) Superscript x is shown below.
The truth of the given function that we have here is The function increases at a constant multiplicative rate.
How to solve for the multiplicative rate of the constantThe table is given as
x 0 1 2 3
f(x) 2 3 4.5 6.75
We have x ranging from 0 to 3 while y ranges from 2 to 6.75.
The observations that we can make about the y values is that they produce the next value at the same rate of multiplication.
This is shown here
2 x 1.5 = 3
3 x 1.5 = 4.5
4.5 x 1.5 = 6.75
Hence we can conclude that it increases at a constant multiplicative rate of 1.5.

To factor the expression 3x2 – 9x, Caleb found the GCF as shown.
List the factors:
3x2 = 3 • x • x
9x = 3 • 3 • x
GCF = 3 • 3 • x • x = 9x2
What is Caleb’s error?
Answer:
Caleb’s error was :
instead of selecting the least exponent ,Caleb took the highest exponent.
Step-by-step explanation:
3x² = 3 • x • x
(in this factorization the exponent of 3 is 1 and the exponent of x is 2)
9x = 3 • 3 • x
(in this factorization the exponent of 3 is 2 and the exponent of x is 1)
• The common factors of 3x² and 9x are 3 and x
In order to determine the GCF ,we have to Compare the exponents of the common factors then take the numbers which have the least exponent value.
• in the factorization of 3x² the exponent of 3 is 1
and in the factorization of 9x the exponent of 3 is 2
The least exponent is 1 Then we take it.
• in the factorization of 3x² the exponent of x is 2
and in the factorization of 9x the exponent of x is 1
The least exponent is 1 Then we take it.
Conclusion:
GCF(3x² , 9x) = 3¹ × x¹ = 3x

By the Congruent Supplements Theorem, we can conclude that,
∠FBC ≅ ∠DBG.
What is Congruent Supplements Theorem?
The Congruent Supplements Theorem states that two angles are said to be congruent if they are supplements of the same angle or even congruent angles.
If there are 4 lines such that, right angles are created when a horizontal line with the points F, B, and G crosses a vertical line with the points A, B, and E at point B. Between angles F and B and A and G, a third diagonal line with the points D, B, and C is intersecting the other two lines at point B. At points A, C, and G, there is a fourth line that joins three other lines.
Drawing Conclusion
In case the angle FBC and angle CBG are supplementary angles, angle DBG and angle DBF are another pair of supplementary angles, and angle CBG is-congruent-to angle DBF, we can apply congruent supplement theorem and draw the following inference,

She decides to save more by depositing $18 each week.
The amount of his savings M depends on the number of weeks elapsed n .
This relationship is represented using the equation M = 18n + 224.
Graphically, how would the line of this relationship change if Cassandra deposited $14 a week?
Please choose an answer.
The line will undergo a downward vertical translation.
The line will undergo a vertical translation upwards.
The inclination of the line will decrease.
The inclination of the line will increase.
Answer:
the inclination of the line will decrease
Step-by-step explanation:
If Cassandra changes the amount she deposits from 18 to 14, the slope changes to 14. So the new equation is M=14n + 224. The 224 is still the same, because that is the initial amount, and the new situation hasn't said anything about changing that, so it will not have any vertical translations. With that being said, as a result the slope will be less, so you can see it as "less vertical", so the inclination of the line will decrease

How to determine the number of days?The expression can be represented using the following ratio:
Ratio = Dragons : Days : Chocolate
For the 2 dragons she has, we have:
Ratio = 2 : 12 : 300
When she gets 4 more dragons, we have:
Ratio = 6 : days : 300
