THINK ABOUT WHETHER THEY ARE ASKING FOR CURCUMFERENCE OR AREA If you want to Make sure to have the most pizza which would you rather two 12 inch medium or one 18 inch large. Justify your answer mathematically
Answer:
The maximum pizza quantity would be with the pizza of 18 inch
Step-by-step explanation:
The size of the pizza in inches depicts its diameter.
Thus, 12 inch pizza means diameter of the pizza = 12 inch and 18 inch pizza means diameter = 18 inch
In case of either the CURCUMFERENCE OR AREA, the pizza with larger diameter will have larger CURCUMFERENCE and AREA as compared to the pizza with smaller diameter.
For instance
Area of 18 inch pizza
[tex]\pi * (18/2)^2\\= 254.34[/tex]Square inch
Area of 12 inch pizza
[tex]\pi * (12/2)^2\\= 113.04[/tex]Square inch
Circumference of 18 inch pizza
[tex]2*3.14*9 = 56.52[/tex]
Circumference of 12 inch pizza
[tex]2*3.14*6 = 37.68[/tex]

Which expression is equivalent to the one below? 6÷9 A. 9.1/6 B. 6.1/9 C. 54 D. 9/6
Answer:
None
Step-by-step explanation:
6÷9=0.666...
9.1÷6=1.5166..
6.1÷9=0.6777...
54 is 54
9÷6=1.5
So none are equal
Answer:
the answer is 6 × 1/9
Step-by-step explanation:
6÷ 9 = 0.666
9 × 1/6 = 1 1/2
6 × 1/9 = 2/3 same as 0.666
54 = 54
9/6 = 1.5

Anthony needed to complete some complex tricks in order to win the 17 and Under State Skate Boarding Championship in Orlando FL. In an attempt to complete a McTwist (a 540-degree burni performed on a cap) and to maximize his air time, Anthony rode his skateboard up a specially designed one of a kind ramp. Unfortunately, he did not make it to the other side of the ramp and crashed his skateboard. His height zoove the ground in feet is a function of his horizontal position from the top of the ramp, also measured in feet The function that relates his height to his distance is h(x)=-x²+2x+8. How far above the ground is the top of the ramp? F a b. How far away from the ramp was Anthony at his maximum height What is his maximum height? C. At his highest point, how high was he above the top of the ramp? d Whea bestemowlad het veled horizontal?
Answer:
did you get the answer yet I have the same question
Answer: a. 8 feet
the first question in part b is 1 and the second part is 9. ( or you could just put 1,9) c. 1 foot taller d. -2 and 4
Step-by-step explanation: you get answer A by looking at the C- value of the equation( in this case it’s 8)
you get the first answer to B by using the axis of symmetry formula -b/2(a) and that equals 1. You get the second answer to B by plugging in 1 into the equation..solve and get 9. So your answers in total should be (1,9)
For part C all you do is subtract the top of the ramp.. which is 8 from your vertex. in other words you do 9-8 and get 1 as your answer for C
Lastly, for D you use the quadratic formula ( or use photo math) and get answers -2 and 4.
If you’re also having problems on part E .. all you have to do is place a dot at point -2, place dot at point 4, place a dot at 8 on the Y AXIS, then place a dot at point (1,9) lastly, connect the dots with a line and the graph should look like an upside down U or V( whatever you think it looks like)

Fatima told her grand children if i give 2 toffees each of you i am left with 3 toffees.But if i try to give 3 toffees each of you i face a short of 3 tofees.How many grand children does fatima have?
Answer:
6
Step-by-step explanation:
two equations can be derived from the question
y - 2x = 3 equation 1
y - 3x = -3 equation 2
y = number of toffees
x = number of children
subtract equation 2 from 1
x = 6
Name 4 fractions that are between 1/5 and 1/7
Answer:
21/240, 22/140, 23/140, 24/140
Step-by-step explanation:
7 and 5 have a common multiple of 140 and
140/7=20 20/140
140/5=28 28/140
21-27 are all numbers b/w 20 and 28
Answer:
21/140, 22/140, 23/140, 24/140
7 and 5 = common multiple of 140.
140/7 = 20 , 20/140
140/5 = 28, 28/140
21, 22, 23, 24, 25, 26, and 27 are the numbers between 20 and 28.

Find the volume and surface area of a rectangular box 3 ft by 1.2 ft by 6 ft The volume is 21.621.6 cubic feet. (Round to the nearest tenth as needed.) The surface area is nothing square feet. (Round to the nearest integer as needed.)
Answer:
Volume = 21.6 ft³
Area = 58 ft²
Step-by-step explanation:
(1)
Applying,
V = lwh......................... Equation 1
Where V = Volume of the rectangular box, l = length of the box, w = width of the box, h = heigth of the box.
From the question,
Given: l = 3 ft, w = 1.2 ft, h = 6 ft.
Substitute these values into equation 1
V = 3×1.2×6
V = 21.6 ft³
(2)
Applying
A = 2(lw+lh+wh)............. Equation 2
Where A = surface area of the box
Also substituting into equation 2
A = 2[(3×1.2)+(3×6)+(1.2×6)]
A = 2(3.6+18+7.2)
A = 2(28.8)
A = 57.6 ft²
A = 58 ft²
What are the first three terms of the sequence defined by the recursive function an = an-1-(an-2-4), when a5 =-2 and a6 = 0?
-14, 14,- 4
6, 10,8
-2 0,2
2, 8, 10
Answer:
6, 10 and 8
Step-by-step explanation:
Given the recursive function an = an-1-(an-2 - 4), when a5 =-2 and a6 = 0?
a6 = a5 - (a4 - 4)
0 = -2 - (14 - 4)
2 = - (a4 - 4)
-2 = a4 - 4
a4 = -2 + 4
a4 = 2
a5 = a4 - (a3 - 4)
-2 = 2 - (a3 - 4)
-2-2 = - (a3 - 4)
-4 = -(a3 - 4)
4 = a3 - 4
a3 = 4+4
a3 = 8
Also
a4 = a3 - (a2 - 4)
2 = 8 - (a2 - 4)
2-8 = - (a2 - 4)
-6 = -(a2 - 4)
6 = a2 - 4
a2 = 6+4
a2 = 10
a3 = a2 - (a1 - 4)
8 = 10 - (a1 - 4)
8-10 = - (a1 - 4)
-2 = -(a1 - 4)
2 = a1 - 4
a1 = 2+4
a1 = 6
Hence the first 3 terms are 6, 10 and 8

C. 6, 10, 8

What is the value of y?
y + 35 = ( y ) + ( y - 31 )
y + 35 = 2y - 31
Add both sides 31
y + 35 + 31 = 2y - 31 + 31
y + 66 = 2y
Subtract both sides y
y - y + 66 = 2y - y
y = 66

Step-by-step explanation:
The expressions 3¹⁰/3², (3⁴)², and (3·3)⁴ are equivalent to the given expression. which is the correct answer would be options (B), (D), and (E).
What are exponential expressions?Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied. To answer the exponential expressions, we may need to apply the relationship between exponents and logarithms.
As per option (B), we have
3¹⁰/3²
3¹⁰⁻²
Apply the subtraction operation in the exponent
3⁸
As per option (D), we have
(3⁴)²
3⁴ˣ²
Apply the multiplication operation in the exponent
3⁸
As per option (E), we have
(3·3)⁴
(3²)⁴
3⁴ˣ²
3⁸
Thus, the expressions 3¹⁰/3², (3⁴)², and (3·3)⁴ are equivalent to the given expression.
Hence, the correct answer would be options (B), (D), and (E).

Given m | n, find the value of x.

Answer:
As 6x+8 = 68

Hope it helps
By question it's given that m || n . So here we can use the properties of parallel lines . One of them which we will use here is ,
corresponding angles are equal .Here the two given angles are corresponding angles hence they will be equal. We create them in order to find the value of x.
[tex]\sf\implies 68^o = 6x + 8^o \\\\\\\sf\implies6x = 68^o - 8^o\\\\\sf\implies 6x = 60^o \\\\\\\sf\implies x = 60^o/6 \\\\\\\sf\implies \boxed{\red{ \sf x = 10^o }}[/tex]
Hence the value of x is 10° .

The favourite colours represent the following angles: red (90°), blue (90°), green (135°) and yellow (45°).
Rule of Three
It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.
Here you can apply the rule of three for finding the angle of each frequency. The total of people (400) represents the total angle of a circumference which is 360°.
For colour - red400 ----------- 360°
100 ------------ r
400r=360*100
400r=36000
r=36000/400
r=90°
For colour - blue400 ----------- 360°
100 ------------ b
400b=360*100
400b=36000
b=36000/400
b=90°
For colour - green400 ----------- 360°
150------------ g
400g=360*150
400g=54000
g=54000/400
g=135°
For colour - yellow400 ----------- 360°

Correct me if I’m wrong it’s been a while but I think u add 3 + 3 + 2+ 2
Answer:
It is 10
Step-by-step explanation:
In order to do perimeter you need to add each corners value, in this case a to B is one side and A to D is another, in order to get from A to B you have to walk 3 units, so their is our first part, now for the second you need to walk from point a to point D which if you do it will be 4 units.
Now we have 2 numbers, 4 and 3, We still have the other side but it will be the same, so you will do 4+4 and 3+3, in this case it will be 8+6 so the answer should be 14. I might be wrong.
