Georgia is making a square sign for her bedroom door. The length of one side is 9 inches. What is the perimeter of the sign?
Answer:
36 inches
Step-by-step explanation:
a squares sides all measure the same length so, if one side is 9 inches all 4 of them are 9 inches. perimeter is all sides added up:
the equation would be 9+9+9+9 which would equal 36
SUPER URGENT Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left.
Is it possible for Sam to eat it all if he will bite 20% of what it is left?
No, Sam will not be able to finish the large hamburger if he only bites 20% of what is left.
What is the percentage?In mathematics, a percentage is defined as a figure or ratio expressed as a fraction of 100. The percent sign, "%," is commonly used to indicate it.
How to solve this problem?Let the size of the hamburger be 100 units.
Here, the first bite was 20% of the hamburger.
So the remaining portion of the hamburger is 100 - (100*(20/100)) = 80 units.
The second bite was 20% of 80%. Again the remaining portion is 80 - (80*(20/100)) = 80 - 16 = 64 units.
After the third bite, the remaining portion is 64 - (64*(20/100)) = 64 - 12.8 = 51.2 units.
After the fourth bite, the remaining portion is 51.2 - (51.2*(20/100)) = 51.2 - 10.24 = 40.96 units.
After the fifth bite, the remaining portion is 40.96 - (40.96*(20/100)) = 40.96 - 8.192 = 32.768 units.
...
Since the criterion is Sam will bite 20% of what is left, this remaining portion is never zero. It will always be a fraction like 0.00000000000001. Again we have to find 20% of 0.00000000000001 and subtract it from 0.00000000000001. So, It will continue.
Therefore, we can conclude that it is not possible for Sam to eat the big hamburger all if he will bite 20% of what is left.

Rewrite the function by completing the square.
f(x)=x^2+14x+8
f(x)=(x+__)^2=__
Answer:
[tex] y = x^2+14x +(14/2)^2 +8 - (14/2)^2[/tex]
And solving we got:
[tex] y = x^2 +14x +49 + 8 -49[/tex]
And we can reorder the terms we got:
[tex] y =(x+7)^2 -41[/tex]
And that would be the equivalent expression for the problem
Step-by-step explanation:
For this case we have the following function given:
[tex] y = x^2 +14x +8[/tex]
And we can complete the square adding the middle of 14 squared and subtracted before like this:
[tex] y = x^2+14x +(14/2)^2 +8 - (14/2)^2[/tex]
And solving we got:
[tex] y = x^2 +14x +49 + 8 -49[/tex]
And we can reorder the terms we got:

And that would be the equivalent expression for the problem
Solve the equation. 24 = 2x – 9
The solution is, the value of x in the equation. 24 = 2x – 9 is: x=16.5.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have
given that, the equation is, 24 = 2x – 9
now, we have to simplify the equation to get the value of x.
24=2x-9
Add 9 to each side
33=2x
Divide both sides by 2
i.e. 33/2 = x
16.5=x
Hence, The solution is, the value of x in the equation. 24 = 2x – 9 is: x=16.5.

A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.
What is a point symmetry?Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).
1) A figure has point symmetry, if it has a rotational symmetry of 180 degrees.
2) An object is said to possess rotational symmetry if it takes the same shape before and after its rotation along its point of rotation.
3) In order for a figure to have reflectional symmetry, there needs to be at least one axis such that when the the figure "folds" over that axis it maps into itself.
4) A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry.
So, all parallelograms have point symmetry.
5) Triangle has no points of symmetry, because there is no up and down shapes in triangle

Hartley has two 4-section spinners, each labeled 1-4. She will spin both spinners a total of 96 times. For each pair of numbers where the pointers of the spinners land on, Hartley will subtract the smaller number from the greater number.
How many possible total outcomes are there?
How many times should Hartley spin a difference of 1?
How many times should Hartley spin a difference of 0?
Answer:
1) Total outcomes of 1 time = 16
2) 36 times
3) 24 times
Step-by-step explanation:
1) Total outcomesIf both spinners are spinning together, and are labelled from 1 to 4, the the outcome are:
{(1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4), (4, 1), (4, 2), (4, 3), (4, 4)}
We can count them to find total no. of outcomes
Total outcomes = 16
2) When Difference = 1Following combinations have a difference of 1
{(1, 2), (2, 1), (2, 3), (3, 2), (3, 4), (4, 3)}
n = 6
Probability of getting such combination is: 6/16

What is the equation of a line passing through (-6,5) and having a slope of 1/3?
Answer:
y = (1/3)x + 7
Step-by-step explanation:
Steps:
(y-y1)=m(x-x1) where m=slope
Using (x1,y1) is (-6,5):
1: (y-5)= (1/3)(x-(-6))
2: (y-5) = (1/3)(x+6)
3: y-5 = (1/3)x + 2 Distribute

Answer:
48cm^2
Step-by-step explanation:
We are given some of the measurements of the piece of cardboard.
First, let's find the lengths of all the sides of the cardboard, as it will be easier to then find the area.
Going in clockwise order, from top to bottom, the dimensions are:
4cm, 7cm, 6cm, 2cm, 10cm, 9cm.
Now, we can easily find the area by using the formula BH=Area. Let's split the cardboard into sections that will be easier to find the area of. Say we split it in two, rather like a sneaker with the person wearing a sock showing at the ankle (I have strange explanations, I know).
To find the top part (the sock part) we can multiply 4 by 7 to get 28.
To find the shoe part, we can multiply 10 by 2 to get 20.
Finally, add these areas together to get the total area.
20 + 28 = 48
Another way to do this (if my sock and sneaker explanation was too chaotic for you) would be to imagine that the cardboard piece were an entire rectangle (ignore that chunk that has been cut out).
The area of that would be 90, from 9 by 10 as the side lengths. Then, from earlier, we know that the width and length of the chunk that has been cut out is 6 and 7, so the area that will be cut out is 42.
Subtract 42 from 90 to get 48.

If y = 6x - 3, which of the following sets represents possible inputs and outputs of the function represented
ordered pairs?
{(0, 3), (1, -9), (2, -15)}
{(0, -3), (2, 15), (4, 21)}
{0, -3), (2, 9), (4, 21)}
{(0, 3), (-2, 15), (4, 21)}
Answer:
{0, -3), (2, 9), (4, 21)}
Step-by-step explanation:
if x = 0 ⇒ y = 6x - 3 = 6(0) - 3 = 0 - 3 = -3
if x = 2 ⇒ y = 6x - 3 = 6(2) - 3 = 12 - 3 = 9
if x = 4 ⇒ y = 6x - 3 = 6(4) - 3 = 24 - 3 = 21

The volume V of a rectangular prism of a particular height varies jointly as the
length I and the width w, and V = 224 ft when I = 8ft and w = 4 ft.
Find I when V = 210 ft' and w = 5ft.
Answer:
6ft
Step-by-step explanation:
Volume of rectangular prism = l x w x h, where h is height. So, we have to work out the height of the first prism in the following way. 224 divided by ( 8 x 4), which gives 7. So, to find l in the second prism, we have to :
L x W x H = 210
L x 5 x 7 = 210
L x 35 = 210
L = 210 divided by 35 = 6
