What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the given information in the question,
Age when John hammered a nail in the tree = 6 years
John returned to the age of sixteen, then the number of years in between that,
16 - 6 = 10 years.
Rate of increase in height of tree per year = 5 cm
Then, after 10 years, the height of the nail of the tree will be,

Determine whether the triangles are similar. or not.
If similar, state how.
A. similar, AA
B. similar, sss
C. Similar, SAS
D. Not similar
Answer: A
Step-by-step explanation:
Answer A:
Angle H is congruent to angle H. because BC and GI are parrellel, and Angles IGB and CBH are corresponding angles. Triangles HBC and HGI are similar
Yes, the triangles are Similar by SAS similarity criteria the triangles are similar.
What is Similarity?Similar triangles have proportional sides and equal corresponding angles. This similarity can be expressed using the symbol "∼".
We have two Triangles named HBC and HGI
As, per the figure CB || IG
We know, A midsegment is parallel to one side of a triangle and divides the other two sides into congruent halves.
Then, HB / BG = HC / HI
Now, add 1 to both side we get
HB / BG + 1 = HC / HI + 1
(HB + BG) / BG = (HC + HI) / HI
BG / BG = CI / HI
Now, In Triangles HBC and HGI
BG / BG = CI / HI
<H is Common.
Thus, by SAS similarity criteria the triangles are similar.

Find the value of x
Answer:
x = 38°
Step-by-step explanation:
this is a four-sided polygon, so the sum of the interior angles measures 360 degrees; formula is (n - 2) · 180 where 'n' is the number of sides
add all four expressions and set equal to 360
5x - 33 + 5x + 13 = 360
10x - 20 = 360
10x = 380
x = 38
check by plugging 38 into each expression to make sure the total is 360
starting in upper left and moving clockwise, the angles are: 75°, 82°, 114°, 89°

Sam walks from home to his school which is 0.75 miles away in 12 minutes. How fast was he walking?
Answer:
v = 3.75 mph
Step-by-step explanation:
Constant speed motion
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:
[tex]\displaystyle v=\frac{0.75\ mi}{0.2 \ h}[/tex]
v = 3.75 mph

A sign says that the price marked on all music equipment is 30% off the original price. You buy an electric guitar for the sale price of $315.
What is the original price?
Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5
so $409.5 is your answer

A lock has a code of 4 numbers between 1 and 20. If no numbers in the

There are 116,280 different codes that can be made with 4 numbers between 1 and 20 without repeating any number.
What are permutation and combination?In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
Here,
To find the number of different codes that can be made with 4 numbers between 1 and 20 without repeating any number, we can use the permutation formula, nPr = n! / (n-r)! where n is the total number of items and r is the number of items we want to choose.
In this case, we have n = 20 (the total number of numbers we can choose from) and r = 4 (the number of numbers we need to choose).
So, the number of different codes that can be made is:
20P4 = 20! / (20-4)! = 20! / 16! = 20 × 19 × 18 × 17 = 116,280
Therefore, there are 116,280 different codes that can be made with 4 numbers between 1 and 20 without repeating any number.

Find the length of arc AB
Answer:
OH HELL NO!
Step-by-step explanation:
Answer:
[tex] m\widehat {AB} = 144\degree [/tex]
[tex]m\widehat {ACB} = 216\degree [/tex]
Step-by-step explanation:
Let the measures of the given arcs be 2x and 3x.
[tex] \because m\widehat {AB} \:\&\: m\widehat {ACB} [/tex] sums up to form a circle.
Therefore,
2x + 3x = 360°
5x = 360°
x = 360°/5
x = 72°
2x = 2*72 = 144°
3x = 3*72° = 216°
[tex] \therefore m\widehat {AB} = 144\degree [/tex]

What is the slope of D and E??
Answer:
-4 and 0
Step-by-step explanation:
Rise over Run would give us the slope.
In the first graph, It goes down 4 while it goes 1 to the right.
This means that -4/1 = -4.
The second graph does not go up or down, meaning 0, while it goes 1 to the right.
This means that 0/1 = 0.

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder on food. How much has he left.
Answer:
Amount left = 2040
Step-by-step explanation:
Given that:
Per year salary = 12,000
Amount spent on transport = 10%
Transport = [tex]\frac{10}{100}*12000[/tex] = 0.1 * 12000
Transport = 1200
Tax = 5%
Tax = 0.05 * 12000
Tax = 600
Total = 1200 + 600 = 1800
Amount left = 12000 - 1800 = 10200
Food = 80% of remainder
Food = 0.8 * 10200
Food = 8160
Amount left after food = 10200 - 8160 = 2040
Hence,
Amount left = 2040
