If BE=9cm, find GE
What is the answer
Answer:
GE = 3 cm
Step-by-step explanation:
BE = 9 cm
Since G is the centroid, therefore:
[tex] GE = \frac{1}{3}(BE) [/tex] => Centroid theorem
Plug in the value
[tex] GE = \frac{1}{3}(9) [/tex]
GE = 3 cm

The population of a town was 489 in 1970. The population has been growing at a rate of 23 percent each year. What is the population of the town in the year 1995
Answer:
86,484
Step-by-step explanation:
The population growth can de determined by using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value = 489
R = interest rate 23
N = number of years =1995 - 1970 = 25
489 x ( 1.23)^25 = 86,484

Answer:
ML=6,CD=7,AC=12,UW=22
Step-by-step explanation:
21.(2x+20):(x+19)=1:2 // x+19=4x+40 // 3x=-21 // x=-7// ML=2x+20=20-14=6
22.(x-3):(4+x)=1:2 // 4+x=2x-6 // x=10 // CD=x-3=10-3=7
23.(x-1):(x+5)=1:2 // x+5=2x-2 // x=7 // AC=x+5=7+5=12
24.(20+x):(x+31)=1:2 // x+31=40+2x // x=-9 // UW=x+31=-9+31=22

A total of 629 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer student tickets sold than adult
tickets. How many adult tickets were sold?
Answer:
350 adult tickets were sold.
Step-by-step explanation:
let x = number of adult tickets
number of student tickets -> x-71
x - 71 + x = 629
2x - 71 = 629
2x = 700
x = 350
A coin is tossed four times. What is the probability of getting tails four times in a row?
Answer:
11/16
Step-by-step explanation:
P(TTHH) = 4C2*(1/2)^4 = 4!/2!*2!*(1/2)^4=6/16
Total Probablity = 1/16 + 4/16 + 6/16
=11/16
A store advertises 15% off an item that regularly sells for $300. what is the sale item? how is a 15% discount similar to a 15% decrease? Explain.
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.

A ticket to the state fair cost $15. The equation y=15x relates the total cost of tickets (y) to the number of tickets purchased (x). Identify the unit rate in the equation.
Answer:
15
.
Step-by-step explanation:
Ticket cost = $15
Cost equation :
y = 15x
x = number of tickets purchased
y = total cost of x tickets
The unit rate in the equation is the Coefficient of x ; which is the sales price of one ticket.
Hence, the unit rate is $15

What is the simplified form of this expression? `sqrt(8x^3 + 24x^2 + 18x)` A. ±(2x + 3)`sqrt(2x)` B. ±(4x + 6) `sqrt(2x)` C. ±(2x + 3)`sqrt(x)` D. ±(4x + 6)`sqrt(x)`
Answer: B
`sqrt(8x^3 + 24x^2 + 18x)` = `sqrt(8x (x + 3/2))` = `sqrt(2x (4x + 6))` = ±(4x + 6) `sqrt(2x)`

Answer:
[tex]b = l\times w[/tex] to guarantee that both formulas are the same.
Step-by-step explanation:
Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.
Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.

To find:
Identify the congruent corresponding parts of [tex]\angle N\cong \angle \_\_[/tex].
Solution:
We have,
[tex]\Delta FUN\cong \Delta TEA[/tex]
We know that corresponding parts of congruent triangles are congruent.
[tex]\angle F\cong \angle T[/tex]
[tex]\angle U\cong \angle E[/tex]
[tex]\angle N\cong \angle A[/tex]
Therefore, the required corresponding part is [tex]\angle N\cong \angle A[/tex].
