The figures are similar. Find x
Answer:
[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

Alexandra needs to rent a car while on vacation. The rental company charges $17.95, plus 15 cents for each mile driven. If Alexandra only has $50 to spend on the car rental, what is the maximum number of miles she can drive?
Answer: 213 2/3 miles
Step-by-step explanation:
first we need to set up an equation to solve
let your equation be in y=mx+b form since we are using a rate
Since this is a word problem, dissect it and match each part with a variable in the slope-intercept equation
y = Budget
m = rate
x = how many miles she can go -- the unknown variable
b = the initial fee
Your equation should be: 50 = 0.15x + 17.95
We want to soIve for x now so first get rid of the coefficient not attached to it
To do this, you do the inverse function of addition, which is subtraction
Subtract 17.95 from both sides
Your new equation will be: 32.05 = 0.15x
0.15 is still attached to x, so we want to do the inverse function of multiplication, which is division
divide both sides by 0.15
Your final answer: 213 2/3 miles

You would like to have $41,000 in 5 years for the down payment on a new house
following college graduation by making deposits at the end of every three months in
an annuity that pays 4.25% compounded quarterly. How much should you deposit at
the end of every three months? How much of the $41,000 comes from deposits and
how much comes from interest?
Answer:
a. You are looking for an annuity that will give $41,000 in 5 years with a quarterly compounding rate of 4.25%.
Convert periods and interest to quarterly rate.
Period = 5 * 4 = 20 quarters
Interest = 4.25 / 4 = 1.0625%
41,000 = Annuity * ( [ 1 + i ] ^n - 1 )/i
41,000 = Annuity * ( [ 1 + 1.0625%]²⁰ - 1) / 1.0625%
41,000 = Annuity * 22.1534596596
Annuity = 41,000 / 22.1534596596
= $1,851
b. There were 20 payments of $1,851 made which totals:
= 1,851 * 20
Cash from deposits = $37,020
Cash from interest = 41,000 - 37,020 = $3,980

Answer:
110 degrees
Step-by-step explanation:
Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.
Answer:
110°
Step-by-step explanation:
Since CDE and FDG are vertical, they are congruent, so:
5x + 15 = 8x - 42
Solve the equation for x
57 = 3x
19 = x
Then solve for one of the angles (I chose CDE but FDG would also work)
5(19)+15
95 + 15
110
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

0.49 × 10 = 4.9
Answer:
$4.9
Step-by-step explanation:

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
