prorate the following expenses and find the corresponding monthly expense. Lan pays a semiannual premium of $450 for automobile insurance, a monthly premium of $135 for health insurance, and an annual premium of $300 for life insurance.
the monthly expense is ____$
Step-by-step explanation:
$135 health insurance
After you do $300÷12=25 so
$25 monthly for life insurance
after you can do $450÷6=$75
and then we add all that up
$135
$75
$25
=That will equal $235 for the monthly cost

Answer:
[tex]\frac{A-2wh}{2(w+h)}=l[/tex]
Step-by-step explanation:
We have to find the formula for the value of 'l'.
So, we will isolate 'l' on one side of the formula.
A = 2lw + 2lh + 2wh
A = 2l(w + h) + 2wh
A - 2wh = 2l(w + h) + 2wh - 2wh
A - 2wh = 2l(w + h)
[tex]\frac{A-2wh}{2(w+h)}=\frac{2l(w+h)}{2(w+h)}[/tex]
[tex]\frac{A-2wh}{2(w+h)}=l[/tex]
Therefore, formula for 'l' will be,
[tex]\frac{A-2wh}{2(w+h)}=l[/tex]
Write an equation of the line that passes through point P and is parallel to the line with the given equation. P(3,5); y=2x-6
Answer:
y = -(5/2)x + 3 is a line perpendicular to y = (2/5)x + 2. This line is also perpendicular to y = (2/5)x + 9 because it has the same slope.
Step-by-step explanation:
A) So the line you are given is written in slope intercept form y = mx + b meaning that the slope of the line is m = 2/5 and the intercept b = 9 (so the line hits the y axis at 0,9). A line that is parallel has to have the same slope so we know our m is the same. So we have y = (2/5)x + b. We need b. It passes (0, 2) since the x coordinate is 0 you know the y intercept is 2 but you can verify this using the point slope formula:
y - y1 = m(x - x1) plug in values
y - 2 = (2/5)(x - 0) now simplify
y - 2 = (2.5)x last solve
y = (2/5)x + 2 see how when the x coordinate is 0 you can automatically use the point slope intercept formula? Neato!
B) Now we want a line perpendicular to y = (2/5)x + 2 and that passes through 0,3. What are the properties of a line perpendicular to a line of the form y = mx + b and passes through (0, 3)? We know that the slope of this new line will be the reciprocal and have the opposite sign of m. So the new slope we will call it mnew = -(1/m) so plug in for m and you get mnew = -(1/[2/5]) if you simplify you get that the mnew = -(5/2). So we have half of our equation for the perpendicular: y = -(5/2)x + b. If you look at (0, 3) you see that the y intercept is 3 so b = 3. So:
The equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, we need to find the equation of a line passing through the point (3, 5) and is parallel to y = 2x-6,
Comparing the given equation with the general equation of line y = mx+c
m = 2 (the slope)
We know that the two parallel lines have equal slope.
Therefore, the required equation is =
y = 2x+c
To find the value of c, put x = 3 and y = 5,
5 = 2(3) + c
c = -1
Therefore,
The required equation is =
y = 2x-1
Hence, the equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

.A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. The total
charge is AED 135
How far, in kilometers, is the trip to the airport?
Given:
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport.
The total charge is AED 135.
To find:
How far, in kilometers, is the trip to the airport?
Solution:
Let x km be the trip to the airport.
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. So, total changes for x km trip is
[tex]T=10+250x[/tex]
The total charge is AED 135.
[tex]10+250x=135[/tex]
[tex]250x=135-10[/tex]
[tex]250x=125[/tex]
Divide both sides by 250.
[tex]x=\dfrac{125}{250}[/tex]
[tex]x=\dfrac{1}{2}[/tex]
[tex]x=0.5[/tex]
Therefore, the trip to the airport is 0.5 km.

[tex]x=\frac{20}{3} =6.67[/tex]
Step-by-step explanation:
[tex]x=15*\frac{4}{9}=\frac{20}{3} =6.67[/tex]
Answer:
6 2/3 or 20/3 or 6.6667
Step-by-step explanation:
Since the figures are similar, you can find x through comparing ratios. To get from 9 to 4, multiply 9 by 4/9. To find x, you must then multiply 15 by 4/9.
15 x 4/9 = 6 2/3 or 20/3 or 6.6667

Don’t take points or I’ll take it back
Answer:
Since there are two angles which are equal in the triangle we can make our equation as-
2x+60=180
(180 cuz the sum of all angles in a triangle will ALWAYS be 180)
so if we solve,
2x=120
x=120/2
x=60
thus x=60
Answer
60
Explanation:
So a given shape will always have a degree of 180.
We know one of the degrees is 60, so we can subtract that to find the missing degree angles: 180 - 60 = 120
We can divide 120 by 2 to spilt that into two degrees: 120 ➗ 2 = 60
(If you have math sense, you can tell that they all have the same angle, so same angle means same degree)

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard deviation of $40. Using the 2 SE rule of thumb, calculate a 95% confidence interval for the mean and select the values that come closest to those that would fill the spaces in the following interpretation: we can be 95% confident that the mean amount of money spent on transportation lies between _____ and _____ .
Answer:
The correct answer is "$159 and $175".
Step-by-step explanation:
The give values are:
Mean,
= $167
Standard deviation,
[tex]\sigma[/tex] = $40
Number of commuters,
n = 100
Now,
⇒ [tex]SE=\frac{\sigma}{\sqrt{n} }[/tex]
On putting the given values, we get
⇒ [tex]=\frac{40}{\sqrt{100} }[/tex]
⇒ [tex]=\frac{40}{10}[/tex]
⇒ [tex]=4[/tex]
By using the 2 SE rule of thumb, we get
= [tex]$(167 - 2\times 4)[/tex]
= [tex]167-8[/tex]
= [tex]159[/tex] ($)
Or,
= [tex](167 + 2\times 4)[/tex]
= [tex]167+8[/tex]
= [tex]175[/tex] ($)
i.e,
$159 and $175
