Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation , where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Answers

168 adult tickets were sold for the school play.

If you have 28 apples, 20 spoiled and you gave away 2,. how much is left

Answers

Assuming you threw away the 20 that spoiled, you'd have 6 left, but you know, you could have kept them, it's very possible that you have 26 left.
answer=6
28-20= 8
8-2=6
so 6 apples are left

A certain colony of bacteria triples in length every 10minutes it's length is now 1millimeter how long will it be in 40minutes

Answers

Bacteria length = 1mm

It will triple four times by 40 min.

This can be shown as 3 to the power of 4; 3⁴ = 81

Original length * growth factor = final length

1 mm * 81 = final length

81 = final length

After 40 mins, the bacteria colony will be 81 mm in length.

Final quetion on this website :D it's worth 30 points :) But there are 3 questions. Anwser them all completely please. I also give thanks and if you need help just pm me

Answers

1. enlarged by a scale factor of 10/1 or basically he made the legnth and the width 10 times bigger
4 times 10=40
6 times 10=60
new dimentions are 40 inches by 60 inches



2.
A: normally we write ratios in (distance):(time) so
marie=325:20
tamara=255:15
B. proportional means that if you conver to fraction and simplify, they will be equall so
325/20=16.25/
255/15=17/1
they are not equal and therefor NOT proportional



3. so we use slope intercept form which is y=mx+b where m=slope and b=y-intercept
so we find the equation
slope=-4/3
we are given the point (0,16)
the y-intercept is where x=0
in (x,y) form, (0,16), x=0 and y=16
b=16
y=-4/3x+16
the x intercept is where the line crosses the x axis or when y=0 so set y=0 so
0=-4/3x+16
subtract 16 from both sides
-16=-4/3x
multiply both sides by -1 because I don't like negatives
16=4/3x
multiply both sides by 3
48=4x
divide both sides by 4
12=x
solution=(12,0)

it will cross at (12,0)




ANSWERS
1.40 inches by 60 inches
2. A.marie=325:20    tamara=255:15
   B.They are NOT proportonal
3. the point (12,0)
1) 4* 10 : 6 * (10) = 40:60 inches.
2) a. (325)/(20) : (255)/(15)    Now reduce
(65)/(4) : (17)/(1)   The ratios are not proportional.
3) [0, 16], [3, 12], [6, 8], [9, 4], [12, 0]
The answer is [12, 0]

There are 3 rivers and after each river lies a grave. So there are 3 rivers and 3 graves. A man wants to leave the SAME amount of flowers at each grave, and be left with none at the end. What happens though is that each time he passes through one of the rivers the number of flowers he has doubles. So he has to start off with what number of flowers, taking into consideration that they double, so that he is left with no flowers whatsoever at the end?
