Segment Partitions
9514 1404 393
Answer:
E = (-2, -1.5), see attached for a plot
Step-by-step explanation:
We want point E such that ...
EC/DC = 3/4 . . . . . . . . the ratio of segment lengths is 3/4
(E -C)/(D -C) = 3/4 . . . . the ratio of coordinate differences is 3/4
4(E -C) = 3(D -C) . . . . . cross multiply
4E = 3D -3C +4C . . . . isolate E term
E = (3D +C)/4 . . . . . . . divide by 4 to find E
__
E = (3(-3, -4) +(1, 6))/4 = (-9+1, -12 +6)/4
E = (-2, -1.5)
The point is plotted in the attached graph.

?/1 If a test is worth 45 points, how many points would a student need to earn to get a score of 90%?
Answer:
40.5 points
Step-by-step explanation:
To start off, I would set up a proportion. You're trying to find how many points out of the total 45 would give you a 90%.
90% as a fraction would be [tex]\frac{90}{100}[/tex].
When you set the two equal to one another, you get this:
[tex]\frac{x}{45} = \frac{90}{100}[/tex]
The bottom numbers are the total amount of points, and the top is how many points a student got.
To solve for x, which is the number of points a student would need to earn, you can cross multiply.
After you do that, you should get:
100x = 4050
To isolate x, you can divide by 100 on both sides.
x = [tex]\frac{4050}{100}[/tex] = 40.5 points
To check your answer, all you have to do is divide.
40.5 ÷ 45 = 0.9
0.9 as a percent is 90%.

A.
14.4 feet x 9.6 feet
B.
144 feet x 96 feet
C.
13.2 feet x 8.2 feet
D.
10 feet x 8 feet
Answer:
A
Step-by-step explanation:
Percentage increment means the part of original value is added to the value. The new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.
What is the percentage of a number?Percentage of a number or ratio is fraction of hundred. It is expressed with the sign "%".
Given information-
The length of the living room is 12 feet.
The width of the living room is 8 feet.
The owner increases the 20 percent of length and 20% width.
Suppose new length is [tex]l[/tex] feet long. As the owner increases the 20 percent of length. Thus the new length will be sum of original length and the 20 percent of it. Hence,
[tex]l=12+\dfrac{20}{100}\times12 \\l=12+2.4\\l=14.4[/tex]
Thus the new length of the living room is 14.4 feet long.
Suppose new width is [tex]w[/tex] feet long. As the owner increases the 20 percent of width. Thus the new width will be sum of original width and the 20 percent of it. Hence,
[tex]w=8+\dfrac{20}{100}\times8 \\w=8+1.6\\w=9.6[/tex]
Thus the new width of the living room is 1.6 feet long.
Hence the new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.

What value of n makes the equation 2(0.5n − 3) = n − 0.25(12 − 12n) true?
Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1

Step-by-step explanation:
Sushil is 6 years older than Brian. Caroline is 5 years younger than Brian. If the total of their ages is 64, how old is the youngest of them
Answer:
Call Brian's age: x, then Sushil's age is: x + 6 and Caroline's age is: x-5
So we have: x + (x + 6) + (x-5) = 64
=> 3x +1 = 64 => x = 63/3 = 21
the youngest of them: 21-5 = 16

Write an equation in Slope-Intercept form that represents a line that passes through the
following points: (2, 4) and (5,-2). Show your work.
Answer:
y = - 2x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, - 2)
m = [tex]\frac{-2-4}{5-2}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 4)
4 = - 4 + c ⇒ c = 4 + 4 = 8
y = - 2x + 8 ← equation of line
Jose deposits $2,500 in an account that earns 5% simple interest. How much is Jose's investment worth after 20 years
Answer:
$5,000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 2500(1 + (0.05 × 20)) = 5000
A = $5,000.00
