Brian will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $44 and costs an additional $0.10 per mile driven. The second plan has an initial fee of $49 and costs an additional $0.08 per mile driven.
For what amount of driving do the two plans cost the same? _ miles
What is the cost when two plans cost the same? $_
Answer:
250 miles
69 dollars
Step-by-step explanation:
Plan 1
44+.10m
Plan 2
49 +.08m
Set the two plans equal
44+.10m = 49 +.08m
Subtract .08m from each side
44+.10m - .08m = 49 +.08m-.08m
44+.02m = 49
Subtract 44 from each side
44 +.02m-44 = 49-44
.02m = 5
Divide each side by .02
.02m/.02 = 5/.02
m = 250
The cost is 44 +.10(250)
44 +25
69
What is the last step whenever dealing with fractions?
Answer:
The last step is to simplify the result if it can be done. To simplify a fraction, you have to find the greatest common factor (GCF) of both the numerator and the denominator. The GCF is the largest number that can be evenly divided into both numbers. In the case of 12 and 96, 12 happens to evenly divide into 96.
find the real numbers x&y so that (x^2+2xy)+i(y-1) = (x^2-2x+2y) - i(x+y)
Answer:
[tex]\displaystyle x_1 = 2-\sqrt{3} \text{ and } y_1 = \frac{\sqrt{3}-1}{2}[/tex]
Or:
[tex]\displaystyle x _ 2 = 2 + \sqrt{3} \text{ and } y _ 2 = -\frac{1+\sqrt{3}}{2}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle (x^2 + 2xy) + i(y-1) = (x^2 -2x + 2y) - i(x +y)[/tex]
And we want to find the values of x and y such that the equation is true.
First, distribute:
[tex]\displaystyle (x^2 + 2xy) + i(y-1) = (x^2 -2x + 2y) +i(-x -y)[/tex]
If two complex numbers are equivalent, their real and imaginary parts are equivalent. Hence:
[tex]\displaystyle x^2 + 2xy = x^2 - 2x +2y \text{ and } y - 1 = -x -y[/tex]
Simplify:
[tex]\displaystyle 2xy = -2x +2y \text{ and }x = 1 - 2y[/tex]
Substitute:
[tex]\displaystyle 2(1-2y)y = -2(1-2y) + 2y[/tex]
Solve for y:
[tex]\displaystyle \begin{aligned} 2(y - 2y^2) &= (-2 + 4y) + 2y \\ 2y - 4y^2 &= 6y -2\\ 4y^2 + 4y - 2& = 0 \\ 2y^2 + 2y - 1 &= 0 \\ \end{aligned}[/tex]
From the quadratic formula:
[tex]\displaystyle \begin{aligned} y &= \frac{-(2)\pm\sqrt{(2)^2 - 4(2)(-1)}}{2(2)} \\ \\ &= \frac{-2\pm\sqrt{12}}{4} \\ \\ &= \frac{-2\pm2\sqrt{3}}{4}\\ \\ &= \frac{-1\pm\sqrt{3}}{2} \end{aligned}[/tex]
Hence:
[tex]\displaystyle y_1 = \frac{-1+\sqrt{3}}{2} \text{ or } y_2 = \frac{-1-\sqrt{3}}{2}[/tex]
Then:
[tex]\displaystyle x _ 1 = 1 - 2\left(\frac{-1+\sqrt{3}}{2}\right) = 1 + (1 - \sqrt{3}) = 2 - \sqrt{3}[/tex]
And:
[tex]\displaystyle x _ 2 = 1 - 2\left(\frac{-1-\sqrt{3}}{2}\right) = 1 + (1 + \sqrt{3}) = 2 + \sqrt{3}[/tex]
In conclusion, the values of x and y are:
[tex]\displaystyle x_1 = 2-\sqrt{3} \text{ and } y_1 = \frac{\sqrt{3}-1}{2}[/tex]
Or:
[tex]\displaystyle x _ 2 = 2 + \sqrt{3} \text{ and } y _ 2 = -\frac{1+\sqrt{3}}{2}[/tex]
HELP PLEASE! 11. Is the set of integers closed under division? Explain why or why not.
If it is not closed, give an example.
First a definition:
A given set is closed under a given operation if, for any given pair of elements of the set under that operation, the outcome also belongs to the set.
With this, we will find that the set of integer numbers is not closed under division.
Now let's be more clear.
The definition particularly means that a set is closed under division only if for any pair of elements of the set, the division of these elements also does belong to the set.
Here we want to see if the set of integers is closed under division. To see that this is false, we just need to find a counterexample.
This is, finding a pair of integer numbers that have a quotient that is not an integer.
A really simple example is:
1 and 2.
2/1 = 2 is integer.
but
1/2 = 0.5 is not integer.
Thus we can conclude that the set of integers is not closed under division.

John bought 3 pants for 25 dollars each and paid with a 100 dollar bill how much change did he get?
Answer:
He got $25 in change.
Step-by-step explanation:
Suppose the balance amount is x.
The cost of 3 pants is 3 × 25 = 75
John paid = $ 100
x = 100 – 75
x = 25
Answer:25
Step-by-step explanation:
25×3=75 then you subtract 100-75=25
The area of a rectangle is 52 inches if the length is two times the width find the dimensions of the rectangle round off your answer to the nearest hundredth
Answer:
about 5.10 by 10.20 inches
Step-by-step explanation:
You can substitute the width for "x"
This would make the length 2x as it is two times the width
Area in a rectangle is Length times Width, so in this case it would be 2x * x
It gives you the area as 52 inches, so you can substitute this in the equation making it 52 = 2x^2
divide by two on both sides: 26 = x^2
take the square root of both sides, and x is 5.0999
Now to find the length, just double it, which rounds out to 10.20
5.0999 rounds to the hundredth as 5.10
so for dimensions you have 5.10 by 10.20

Doug's dive takes himmeters.
Answer:
13.8
Step-by-step explanation:
His dive once he hits the water and goes below the surface water line is in the same direction as his dive off the platform. That's very important when you start to consider direction. So you add. Be sure and read this paragraph again.
Dive = platform + under the surface
Dive = 10 + 3.8
