Tickets to the zoo cost $8 per child and $12 per adult. The zoo sold $5500 in tickets yesterday.
a. Write an equation to model the ticket sales for yesterday. Use c to represent child tickets
and a to represent adult tickets.
b. 125 more child tickets than adult tickets were sold. That can be modeled using the equatic
c = 125 + a. How many child tickets were sold? How many adult tickets were sold? Show
your work.
Answer:
a. 12a + 8c = 5500
b. 225 adult tickets
350 child tickets
Step-by-step explanation:
a. 12a + 8c = 5500
b. 12a + 8(125 + a) = 5500
12a + 1000 + 8a = 5500
20a = 4500
a = 225 adult tickets
125 + a = 125 + 225 = 350 child tickets

H+ ions increase in concentration at lower pH values. Calculate how many more H+ ions there are in a solution at a pH = 2 than in a solution at a pH = 6. Find the concentration of H+ ions at a pH = 2 and at a pH = 6 in Table B. Then divide the concentration of H+ ions at a
pH = 2 by the of H+ ions at a pH = 6. Record your answer in Table C.
What is the concentration of H+ ions at a pH = 2?
mol/L
What is the concentration of H+ ions at a pH = 6?
mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
Answer:
What is the concentration of H+ ions at a pH = 2?
⇒ 0.01 mol/L
What is the concentration of H+ ions at a pH = 6?
⇒ 0.000001 mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
⇒ 10,000
Step-by-step explanation:
Answer:
What is the concentration of H+ ions at a pH = 2?
0.01
What is the concentration of H+ ions at a pH = 6?
0.000001
How many more H+ ions are there in a solution at a

Ahmed owns a land of breadth (x+7) units &having an area of 2+ 14x + 49 sq. Units. (i)Find its length.
Answer:
l = (x+7) units
Step-by-step explanation:
Given that,
Breadth of the rectangle, b = (x+7) units
Area of the rectangle, [tex]A=x^2+14x+49[/tex]
The area of a rectangle is given by :
[tex]A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}[/tex]
So, the length of the land is (x+7) units.

The coordinates of the vertices of a triangle are A( 2,3) , B ( 9,1) , C ( 12,14) Suppose each coordinate is multiplied by 3. What is the perimeter of this triangle?
9514 1404 393
Answer:
about 106.5 units
Step-by-step explanation:
The length of each side is found using the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of side AB is ...
d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28
The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...
AB +BC +CA = 7.28 +13.34 +14.87 = 35.49
__
Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...
3(35.49) ≈ 106.5 . . . . units

Bethany bought a box of markers. She gave 6 to her friend. If Bethany now has 52 markers, how many markers were in the box she bought?
Answer:
58 markers
Step-by-step explanation:
52 + 6 = 58
Answer:
58 markers
Step-by-step explanation:
x-6=52 Set up the problem. "x" represents the number of markers.
+6 +6 Add 6 to both sides to isolate x
x =58

The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.
Time (days)
Cost ($)
3
75
4
100
5
125
6
150
A. [tex]\frac{1}{25}[/tex] dollars per day; the cost is $25 for each day.
B. [tex]\frac{75}{1}[/tex] dollars per day; the cost is $75 for each day.
C. [tex]\frac{25}{1}[/tex] dollars per day; the cost is $25 for each day.
D. [tex]\frac{1}{150}[/tex] dollars per day; the costs $1 for 150 days
Answer: C. (25)/(1) dollars per day; the cost is $25 for each day.
$25/ 1 day or $25 a day
Step-by-step explanation:
Answer:
The rate of change is 25. It means the cost increased by $25 per day.
Step-by-step explanation:
The given table is
Time (days) Cost ($)
3 75
4 100
5 125
6 150
It means the graph of this constant function passing through the points (3,75) and (4,100).
If a line passing through two points, then the slope of the line is
Therefore the rate of change is 25. It means the cost increased by $25 per day.

Academy is offering a 12% discount on all of their sporting good supplies. What would be the sale cost of a basketball with an original price of $140?
Answer:
$123.20
Step-by-step explanation:
First, convert 12% into a decimal, 12% = .12, now we multiply the discount by the original, so .12x140 which equals $16.80 then we subtract 16.8 from 140 giving you $123.20.
