In the diagram, point X is the centroid. If
EX=8, what is the length of XC ?
Answer:
16
Step-by-step explanation:
If X is the centroid that means that EC is a median along with the other lines that intersect inside the triangle. Medians drawn from a triangle have a special rule; this rule is that all medians have a 2:1 ratio between the different sections of one median. For example, EC is one median with the two sections XC and EX. Therefore XC and EX have a 2:1, with the 2 representing the longer section closest to the vertex. This means that XC is double EX, so to find XC simply double EX measurement, which is 8. So XC must equal 16.

Find a coordinates of the midpoint of the line segment with the given endpoints (7,4), (9,-1)
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point = [tex](\frac{7+9}{2},\frac{4+(-1)}{2})\\[/tex]
Midpoint = [tex](\frac{16}{2},\frac{4-1}{2})[/tex]
Midpoint = [tex](\frac{16}{2},\frac{3}{2})[/tex]
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).
The V(t)=1.50(1.17)^t represents the value V (t), in dollars, of a comic book t years after its purchase in 2000. Determine the annual growth rate in the value of the comic book and its value in 2025.
Answer:
Growth rate is 17%
2025 value is $76
Step-by-step explanation:
Here, we want to determine the annual growth rate
The general equation form is;
F = l( 1 + r)^n
where F is the future value
I is the initial value
r is the growth rate
n is the numbering years
To get the growth rate, we simply equate what we have in the bracket to 1 + r
Thus;
1 + r = 1.17
r = 1.17-1
r = 0.17
0.17 is same as 17/100 which is same as 17%
Secondly, we want to get the value of the book in 2025
What we have to do here is to substitute (2025-2000) for t which is 25
We have;
V(t) = 1.50(1.17)^25
V(25) = 75.986 which is approximately 76
We will see that the annual growth rate is of 17%, and in the year 2025, the value will be $75.99.
Exponential growth functions:
A general exponential growth can be written as:
f(x) = A*(1 + r)^x
Where A is the initial value and r is the growth rate. Now we can rewrite our function to get:
V(t) = 1.50*(1 + 0.17)^t
Then you can see that the growth rate is 0.17, or 17% in percentage form (to get it just multiply it bt 100%).
To get the value of the comic book in 2025 you just need to evaluate the function in t = 25 (25 years after the 2000).
V(25) = 1.50*(1 + 0.17)^25 = 75.99
So the value in 2025 is $75.99

Step-by-step explanation:
If you multiply 4 to both sides of the equation, it would be:
4y = 3x + 4
Then, if you put the variables on one side, and the numbers on the other,
3x - 4y = -4

g(x) = 2x - 4
h(x)=x+2
Find (g - h)(-4)
=============================================
Work Shown:
(g-h)(x) = g(x) - h(x)
(g-h)(x) = (2x-4) - (x+2)
(g-h)(x) = 2x-4 - x - 2
(g-h)(x) = x - 6
(g-h)(-4) = -4 - 6
(g-h)(-4) = -10
--------------------
An alternative method:
g(x) = 2x-4
g(-4) = 2(-4)-4
g(-4) = -8-4
g(-4) = -12
h(x) = x+2
h(-4) = -4+2
h(-4) = -2
(g-h)(-4) = g(-4) - h(-4)
(g-h)(-4) = -12 - (-2)
(g-h)(-4) = -12 + 2
(g-h)(-4) = -10
Aliya loves music. She currently has 200 songs in her computer . The songs fall in five genres country, jazz, pop, rap, and rock. Find the percentage that is rock Country-40 Jazz- 18 Pop-52 Rap- 30 Rock-60
Answer: 30%
Step-by-step explanation:
There are 200 songs in total.
Out of these 200, there are 60 Rock songs.
The percentage of Rock is therefore:
= Rock / Total songs * 100%
= 60/200 * 100%
= 30%

Alright so this problem is like that other one i did where line RQx2 is equal to line SU
First we set up an equation
x+3=x-2
because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of
x+3=2x-4
step 1 subtract each side by 2x
-1x+3=-4
step 2 subtract each side by 3
-1x=-7
divide each side by -1
x=7
Next we plug in x (7) so 7-2=5
line RQ=5
One number is twelve less than another number. The total of the two numbers is 154. Find both numbers.
Answer:
83 and 71
Step-by-step explanation:
One number is twelve less than the other number
Let the one number be x
Let the other number be x - 12
Since one number is 12 , less than the other number, and the total of the two numbers is 154, then, we'll have
x + x - 12 = 154
2x = 154 + 12
2x = 166
x = 83
Therefore, both numbers would be;
First number = x = 83
Second number = x - 12 = 83 - 12 = 71
Juan bought a basketball for 40% off. If
he paid $36 for the basketball, what was
the original price?
Answer:
$24
Step-by-step explanation:
since 40% is in 100% i did 100 - 40 which i got 60
then it says that he paid $36 so I subtracted 60 - 36 and I got $24 as the answer iihope this helps! :)
100 - 40 = 60
60 - 36 = 24
The original price when he paid $36 for the basketball should be considered as the $24.
Calculation of the original price:Since
Juan bought a basketball for 40% off And, If he paid $36 for the basketball.
So it be like
= 60% of $100 - $36
= $60 - $36
= $24
Hence, The original price when he paid $36 for the basketball should be considered as the $24.
