Answer:

  21040

Step-by-step explanation:

As with base-10 addition, when the sum is equal to the base or more, a "carry" is generated into the next place value column. Useful equivalents here are ...

  5₁₀ = 10₅

  6₁₀ = 11₅

  7₁₀ = 12₅

  9₁₀ = 14₅

  10₁₀ = 20₅

The addition is shown in the attachment. The sum is 21040₅.

A music festival charges $54 and 95 per ticket sold on the day of the event. A ticket purchased before the festival cost only $39.95. There were only 20,000 tickets sold for a total of $925,000 how many tickets did they sell at the music festival? How many tickets did they sell before the music festival?

Answers

b=number of ticets sold before
a=number of tickets sold after

cost of a ticket=number of tickets times cost per ticket
beforecost=39.95b
aftercost=54.95a

total cost=925000
39.95b+54.95a=925000

total number tickets=20000
b+a=20000

we have

39.95b+54.95a=925000
b+a=20000
multiply second equation by -39.95 and add to first equatin
39.95b+54.95a=925000
-39.95b-39.95a=-799000 +
0b+15a=126000

15a=126000
divide bot sides by 15
a=8400

sub back
b+a=20000
b+8400=20000
minus 8400 both sides
b=11600

I can see your problem immediately . . . there's no question !
Since y^2 + 6y + 9 can be factored, the polynomial is not factored all the way. To factor it, try (y + 3)(y+3) or simply put, (y +3)^2. Don't forget to keep the 6y^2, so the completely factored version would be : 6y^2 (y+3)(y+3)

The length of line segment AK is 640 meters. ∆ABC, ∆CDF, and ∆FJK are similar, and 2AC = CF = 2FK. The first pillar is 20 meters tall. What is the area of ∆CDF

Answers

A to K = 640 meters

2AC = CF = 2FK


2AC = 2(160) = 320
CF = 320
2FK = 2(160) = 320

AC = 160
CF = 320
FK = 160
AK    640

BG = 20 m ; Area = (160m*20m) / 2 = 3,200/2 = 1,600 m²

20:160 = x : 320
20*320 = 160x
6,400 = 160x
6,400/160 = x
40 = x

Area of CDF = (320m*40m) / 2 = 12,800 / 2 = 6,400 m²

Answer:

no . of items = 10

Position of mean = (n+1)/2

In the data 5.5 item is the average of 5th and 6th item

median = (x+2+x+4)/2

or 25= (2x+6)/2

11,13,15,19,_,_,30,39,46

The middle number is the first dash which is represented by x+2 which is equal to 25

25-2=23 which is x

Dash 2 which is represented by x+4 is equal to 23+4=27
