Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%

Elise and her dad are planning to attend the state fair. An adult ticket is $21.00. The price of an adult ticket is $10.00 more than two thirds the price of a student ticket.
Answer:
C)two thirds x + 10 = 21
Step-by-step explanation:
The equation for determining how much it would be paid for the student tickets is shown below:
Given that
The ticket of an adult is $21
Now let us assume the price of the student ticket be x
So two third would be 2 ÷ 3x
And for adult it would be
2 ÷ 3x + 10
Now the equation is
2 ÷ 3x + 10 = 21
So after solving this the option c is correct
And the rest of the options are wrong
Hannaford sells two sizes of cheerios cereal. The smaller box contains 9 ounces and
costs $2.50. The larger box contains 20 ounces and and costs 3.79. What is the
difference in cost in dollars per ounce between the two sizes?
Quantity of cheerios cereal in the smaller box Hannaford sold = 9 ounces
Cost of nine ounces of cheerios cereal = $2.50
Cost of one ounce of cheerios cereal :
[tex] = 2.50 \: \div \: 9[/tex]
[tex] =\color{plum}\$ 0.27[/tex]
Cost of one ounce of cheerios cereal in the smaller box = $0.27
Quantity of cheerios cereal in the larger box Hannaford sold = 20 ounces
Cost of nine ounces of cheerios cereal = $3.79
Cost of one ounce of cheerios cereal :
[tex] = 3.79 \div 20[/tex]
[tex] =\color{plum} \$0.18[/tex]
Cost of one ounce of cheerios cereal in the larger box = $0.18
Difference in their cost per ounce :
[tex] = 0.27 - 0.18[/tex]
[tex] =\color{plum}\bold{\$ 0.09}[/tex]
Therefore, the difference in cost in dollars per ounce between the two sizes = $0.09

Emmanuel bought adult and childron tiokots for his fomily to see g show. He bouant a total of 18 tickets The adult tickets cost $20 and the children tickets cost 15 If he spent a total of 1320 how many children tickets did he buy?
Answer:
8 children tickets 10 adult tickets
Step-by-step explanation:
The total amount should be $ 320 not 1,320 because if you divide that amount into 18 tickets it will be an average of $73.333 per ticket
A= adults C= children
A+C =18
C= 18-A
20A + 15(18-A) = 320
20A +270 -15A = 320
5A = 50
A= 10
10 adults 8 children
10x$20 =$ 200 8x$15 =$ 120
$200+$120 =$ 320
Answer:
The answer is 10 adult tickets and 8 children tickets.
Step-by-step explanation:

Three consecutive integers are listed in increasing order. If their sum is 102, what is the second integer in the list?
Answer:
Second integer = 34
Step-by-step explanation:
Given:
Sum of 3 consecutive integers = 102
Find:
Second integer
Computation:
Assume;
First integer = x
So,
Second integer = (x+1)
Third integer = (x+2)
So,
x + x + 1 + x + 2 = 102
3x + 3 = 102
x = 33
Second integer = (x+1)
Second integer = (33+1)
Second integer = 34

Find the distance between the points (3, 7) and (3, -5).
Answer:
The total distance is 12
Step-by-step explanation:
Since the x value stays the same, we only need to find the difference in y values
The first value, 7, is 7 away from 0
The second value, -5, is 5 away from 0
We can add these together to find the total distance
7 + 5 = 12
write an equation from the table.
Answer:
Step-by-step explanation:
.
Answer:
y=-2x+7
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex]
You can pick any two equations. In this example, I chose the firsts 2.
(0,-7) and (1,-9)
Plug into the slope formula,
-9+7 over 1-0 which is -2/1 or -2
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -2 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -7. Thus, when plugging in the equation, y=-2x-7

If square A has a side of length 5 inches, how many times bigger is the area of square B if it has a side of length 25 inches?
Answer:
24 times
Step-by-step explanation:
It is given that :
The length of the side of square A = 5 inches
The length of the side of square B = 25 inches
Therefore, area of square A = 5 x 5
= 25 square inches
Similarly, area of square B = 25 x 25
= 625 square inches
Therefore, number of times the square B is bigger than the square A is given by :
[tex]$=\frac{625-25}{25}$[/tex]
[tex]$=\frac{600}{25}$[/tex]
= 24
Thus the square B is 24 times bigger than square A

A box is a cuboid with dimensions 29cm by 15cm by 20cm all measured to the nearest centimetre.? disc cases are cuboids measured 1.4cm by 14.2 by 19.3 to t he nearest millimetre. show that 19 disc cases stacked straight down will definitely fit in the box
Answer:
See explanation.
Step-by-step explanation:
The question requires you to determine the volume of both the box and the disc case then find how many of the disc cases can fit in to the box.
The volume of the box
V= l*w*h
V= 29 * 15 * 20 = 8700 cm³
The volume of the disc case
V=l*w*h
V=1.4 * 14.2*19.3
V=383.684 cm³
The number of disc cases that fit in the box will be;
8700/383.684
22.67
In this calculation, it is clear that 19 of these disc cases will definitely in the box because the box can accommodate 22 of these disc cases.
