If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%
The expression best describes the new length of the cookie will be 1.25y.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
An uncooked gingerbread cookie is y centimetres long. After it is baked, the length of the cookie increases by 25%.The initial length of the cookie is y after baking the length is increased by 25%
= y + 25%y
= y + ( 25 / 100 ) y
= y + 0.25 y
= 1.25 y
Therefore the expression best describes the new length of the cookie will be 1.25y.

As an estimation we are told £3 is €4.
Convert £10.70 to euros.
Give your answer rounded to 2 DP.
Answer:
From the estimation,
£10.7 = €14.27
Step-by-step explanation:
Given the conversion rate between the pounds and the euro currencies, we are to convert an amount in pounds to euros
From the estimate;
3 pounds = 4 euros
Thus;
10.7 pounds = x euros
We are using x since the value in euros is not known presently.
To move from here, we simply cross multiply.
That would give;
3 * x = 4 * 10.7
3x = 42.8
x = 42.8/3
x = 14.2666
x = €14.27

Answer:
1) I think its helps to rename a function as tenths or hundredths when you want to write the decimal equivalent because for example if you wanted to rename this function 6/25 to 24/100 you can know were you put it in decimal (0.24).
2) It was a good idea to change 4/16 to 1/4 to determine a decimal equivalent because it would be easier to put 1/4 in a decimal equivalent.
3) You write the decimal 0.12 as 3/25

Write the following series in summation notation. 1, 4, 9, 16, 25, 36
Answer:
[tex]\sum_{k=0}^{n}2k+1[/tex]
Step-by-step explanation:
Let's take a look at how much is added from one term to the next and see if we can recognize a pattern!
1 to 4: +34 to 9: +59 to 16: +716 to 25: +925 to 36: +11If we start by listing the first number in sequence, 1, we get the familiar list:
1, 3, 5, 7, 9, 11
Of course, this is simply the list of the first six odd numbers. To get the first term, we add the first 1 odd number, to get the second, we add first 2 (1 +3), to get the third, we add the first 3 (1 + 3 + 5), and so on. How do we shorten these sums so we're not writing out dozens of terms as the sequence goes on?
Sigma notation: Summing things upFor situations where we're adding up a lot of numbers that follow a predictable pattern, mathematicians came up with something called summation notation, or sigma notation, coming from the Greek S, Σ, short for "sum". Here's a simple example of a sum expressed in sigma notation:
[tex]\sum_{n=1}^{4}n=1+2+3+4[/tex]
Let's break this down. n acts as our counter. [tex]\sum_{n=1}[/tex] sets it to start counting at 1, and tells us to stop counting at n = 4. The [tex]\sum n[/tex] bit tells us what pattern we'll be following, in this case, each step of the way we'll be adding the value of the counter.
In summationSo how do we express the sum 1 + 3 + 5 + ... in sigma notation? First, we need an expression that describes the pattern algebraically. Ever odd number is 1 away from an even number, so we can either describe our list with the expression [tex]2k+1[/tex] (if we start at k = 0), or [tex]2k-1[/tex] (if we start at k = 1). I'll choose [tex]2k+1[/tex] for this problem.
We want to start counting at k = 0 , and we can choose whatever we want for our stopping point. Let's call that stopping point n, for the nth term in the series. In sigma notation, we can now write this series in the form
[tex]\sum_{k=0}^{n}2k+1[/tex]
Let's test it out for the first few values to see if it works!
n = 0: [2(0) + 1] = 1n = 1: [2{0) + 1] + [2(1)+1] = 1 + 3 = 4n = 2: [2{0) + 1] + [2(1) + 1] + [2(2) + 1] = 1 + 3 + 5 = 9Checks out!
To write the series in summation notation, we have to identify a pattern. After we identify the pattern, we get that the notation is:
[tex]S = \sum_{n = 1}^{\infty} n^2[/tex]
Terms:
The first term is 1, which is also the square of 1, as [tex]1^1 = 1[/tex]The second term is 4, which is also the square of 2, as [tex]2^2 = 2[/tex]The third term is 9, which is also the square of 3, as [tex]3^2 = 9[/tex]The fourth term is 16, which is also the square of 4, as [tex]4^2 = 16[/tex]The fifth term is 25, which is also the square of 5, as [tex]5^2 = 25[/tex]The sixth term is 36, which is also the square of 6, as [tex]6^2 = 36[/tex]From this, we can get a pattern that each term is the square of the index, and the notation is:
[tex]S = \sum_{n = 1}^{\infty} n^2[/tex]

9) v - 15 = -27 10) n + 16 = 9
Answer:
9) v= -12
10) n= -7
Step-by-step explanation:
9) v - 15 = -27
Add 15 from both sides
i.e. v - 15 + 15 = -27 + 15
v = -12
10) n + 16 = 9
Subtract 16 from both sides
i.e. n + 16 - 16 = 9 - 16
n = -7

Answer: 18 square feet.
Step-by-step explanation:
You can find the surface area of the ice cubes by taking the area of each square side and multiplying it by 6.
1 * 1 = 1, so each side is 1 square foot.
There are six sides on a cube, so each ice cube has a surface area of six feet squared.
There are three ice cubes there, so 3 * 6 = 18 square feet.
Three ice cubes have a surface area of 18 feet squared.
The circle passes through the point (3,6). What is it’s radius?
Answer:
c. 5
Step-by-step explanation:
In the attached image we can calculate the radius in a very simple way, if we focus on the axis of the "y" we have that there is a distance that would be the diameter of the circle and goes from -2 to 8.
Between -2 and 8, there is a quantity of 10 units, since:
8 + 2 = 10
they are added because we want to know the total distance, therefore the diameter is 10, and we know that the radius is half the diameter, so:
r = d / 2
r = 10/2
r = 5
therefore the radius is 5 units, that is, the answer is c. 5
4(x + 2) = 4x + 2
Are these two Equivalent
Answer:
no they're not
Step-by-step explanation:
4(x+2) = 4x +8
4x+2= 4x+2
Answer:
No they are not equivalent
First we would have to solve 4(x+2)
In order to solve this we need to multiply. So 4×X is equal to 4x. 4×2=8 Therefore when solving Its 4x+8..and 4x+8 is not equivalent to 4x+2
what is the slope of the line ?
Answer:
-3/4
Step-by-step explanation:
To find the slope of a line, you need to see how much it "rises" over a certain amount of "run". In other words, for a given amount of distance traveled along the x axis, how much it traveled vertically along the y axis. In this line, for every 4 units moved to the right, the line goes up by -3 units. Therefore, the slope of the line is -3/4. Hope this helps!
Answer:
m = -4/5
Step-by-step explanation:
Slope is the difference in y-values/difference in x-values.
Since the graph goes 4 units down and 5 units right, the slope is -4/5.

in your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you were getting dressed, and you can’t see the color of the socks. How many socks must you pick to absolutely guarantee that you have a pair of blue socks to wear?
A.) 14
B.) 24
C.) 4
D.) 3
E.) 2
Answer:
A. 14
Step-by-step explanation:
The smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A)
What is pigeonhole principle?If there are n objects to be putted into m containers such that n > m, then at least one container will have two objects.
Suppose the worst is happening when you're pulling the socks out.
The total number of colors is 2.
Now the worst case is when the pair is not completed until we draw all the yellow color.
That will happen at 12 + 1 = 13 draws (pair needs 2 blue, and the worst will happen that in initial trials, the yellow socks are not letting the pair get completed, which means at max 1 blue sock and rest 12 socks are drawn, which will get at max 13 draws).
But now any more sock pulled will have to be falling into the blue color category we already have. (this is exactly the pigeonhole principle's use).
After 13 times, you will start getting blue socks.
Since you need a pair of blue socks, you need to pull out socks 1 more time.
So total 14 pulls were required if the conditions were like resisting us at maximum.
In most of the cases, we might not need those 14 pulls, but 14 pulls is the minimum number that will assure you that the socks pulled have a blue pair of socks.
If the conditions are not worst, we would be lucky and that
Thus, the smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A is correct).

Mr. Ray wanted to measure the height of a light post. He placed a mirror on the ground 32 feet from the light post, then walked backwards until he was able to see the top of the light post. His eyes were 6 feet above the ground and he was 9 feet from the mirror. Using similar triangles, find the height of the light post to the nearest tenth of a foot.
Answer:
Option (2) is the answer.
Step-by-step explanation:
From the figure attached,
AB represents the length of Mr. Ray, ED represents the light post and the mirror was placed at point C.
Here AB = d = 6 feet
CD = w = 32 feet
BC = f = 9 feet
Since both the triangles ABC and EDC are similar, their corresponding sides will be in the same ratio.
[tex]\frac{AB}{DE}=\frac{BC}{CD}[/tex]
[tex]\frac{6}{h}=\frac{9}{32}[/tex]
h = [tex]\frac{6\times 32}{9}[/tex]
h = 21.33 feet
h ≈ 21.3 feet
Therefore, height of the light post is 21.3 feet.
