Shown is a pentagon, with the size of
each angle shown. Work out the largest angle.
Answers
Answer:
160°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
x + 10 + 2x + 10 + x + 10 + 2x+ x + 20 = 540 , that is
7x + 50 = 540 ( subtract 50 from both sides )
7x = 490 ( divide both sides by 7 )
x = 70
Then
largest angle = 2x + 10 = 2(70) + 10 = 140 + 10 = 150°
The solution is : the largest angle is 150°.
What is the polygon?A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

Identify the explicit formula for the sequence given by the following recursive formula:
(see picture below)
A) f(n) = 2 – 4(n – 1)
B) f(n) = –4 + 2(n – 1)
C) f(n) = 4 – 2(n – 1)
D) f(n) = –2 + 4(n – 1)
Answers
If f(n) = f(n - 1) + 4, then
f(n - 1) = f(n - 2) + 4
and substituting this into the first equation gives
f(n) = f(n - 2) + 2•4
Similarly,
f(n - 2) = f(n - 3) + 4
so that
f(n) = f(n - 3) + 3•4
and so on.
Note the pattern:
f(n) = f(n - k) + k•4
so that when k = n - 1, we have
f(n) = f(n - (n - 1)) + (n - 1)•4
or
f(n) = f(1) + 4 (n - 1)
so that
[D] f(n) = -2 + 4 (n - 1)

The sum of 139 and the product of a number raised to the third power and 17. In symbols, the phrase is written as.
Answers
Answer:
y = 139 + x³ + 17
Step-by-step explanation:
The word "sum" means the amount resulting from addition in an equation. This means that we are adding all of these numbers together.
The word "product" means the amount resulting from multiplication in an equation, this means we need to find the product of a number multiplied by itself three times. Since we don't know what number it is, we can use the variable 'x'.
So, you would be adding 139, the product of x³, and 17, which would be written as y = 139 + x³ + 17.

135% as a fraction or a mixed number fully simplified please
Answers
Answer:
135% = 27/20 = 17/20 as a fraction
Step-by-step explanation:
Step 1: Write down the percent divided by 100 like this:
135% = 135/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As 135 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(135,100) = 5. So,
(135÷5)/(100÷5) = 27/20 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 135/100 is also equal to 1 7/20 when expressed as a mixed number.

The number of shelves would be 6.
The length of the board and the shelves are fractions. A fraction is made up of a numerator and a denominator. An example of a fraction is 1/8. 1 is the numerator and 8 is the denominator.
In order to determine the number of shelves Curtis cut, we would divide the length of the board by the length of each shelf.
Number of shelves = length of the board / length of the shelf

Answers
Based on the information given, the student should score at least 77 in the last exam.
Since the student wants to get an average of at least 80. Therefore, the total scores should be:
= 80 × 3 = 240
The student received scores of 85 and 78 on the first two exams. The addition of this will be:
= 85 + 78 = 163
Therefore, his score in the last exam should be:

pls help. I dont really understand these problems. fraction area and perimeter
Answers
Answer:
Perimeter: 14 9/10 cm
Area: 11 7/10 cm^2
Step-by-step explanation:
First, you must find the perimeter of the rectangle. The definition of perimeter in terms of mathematics are: the continuous line forming the boundary of a closed geometric figure. To find the perimeter of any shape, you must add up all the sides. Thus:
2 1/4 + 2 1/4 + 5 1/5 + 5 1/5 = ?
To put it simpler -
2(2 1/4 + 5 1/5) =
4 5/10 + 10 4/10 =
14 9/10 cm
Then, you must find the area of the rectangle. The definition of the area are: the extent or measurement of a surface or piece of land. In other words, the amount of space an object takes up. You must multiply the length and width of the rectangle to find the area.
Formula of area:
A = L x W
A = 2 1/4 x 5 1/5
A = 9/4 x 26/5
A = 234/20
A= 11 7/10 cm^2
To sum it up, the perimeter of the rectangle is 14 9/10 cm and the area 11 7/10 cm^2.

3 poil The ratio of the number of Taylor's CDs to the number of Dave's CDs is 7 to 9. Taylor has 84 CDs. Together how many CD's do they have?
Answers
Answer:
192
Step-by-step explanation:
The 7 part of the ratio relates to Taylor's 84 CDs
Divide the amount by 7 to find the value of one part of the ratio.
84 ÷ 7 = 12 ← value of 1 part of the ratio, then
9 parts = 9 × 12 = 108 ← number of CDs Dave has
Total CDs = 84 + 108 = 192

Answers
Answer:
The data covers 58 to 86 = 28 for the total distance
Each quartile will occupy a difference of 28/4 = 7
58 - 65 = first quartile (or lower quartile)
65 - 72 = second quartile
72 - 79 = third quartile
79 - 86 = fourth quartile (or upper quartile)
Notice that the first quartile ends at 65 and the second quartile starts at 65
If you divide a straight line accordingly there must not be an empty space between the first and second quartile to be all inclusive
The median is the middle point or 58 + 14 = 72
14 points lie in the range of 58 to 72 and
14 points lie in the range of 72 to 86
