The value of the internal angle m from the heptagon is given by the equation m = 141°.
What is the sum of a polygon's internal angles?The formula returns the sum of the internal angles of a polygon.
The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees
Given the data,
Let's call the polygon a heptagon.
The polygon has n sides, which equals 7 sides.
Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )
7θ = 180 ( 7 - 2 )
7θ = 180 ( 5 )
When we simplify the equation, we obtain 7 = 900°.
A = 900° denotes the sum of the internal angles of the polygon.
And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°
900° = m + 759°
Subtracting 759° on both sides of the equation , we get
m = 141°
Hence , the interior angle ∠B = 141°

Jason has 34 raspberry scones and 51 blackberry scones. He wants to make as many identical bags of scones as possible. Each bag should have an equal number of raspberry scones and an equal number of blackberry scones. What is the greatest number of bags Jason can fill? Explain how you know.
Answers
Answer: The greatest number of bags Jason can fill = 17
Step-by-step explanation:
Given: Jason has 34 raspberry scones and 51 blackberry scones.
To make identical bags of scones as possible.
Each bag should have an equal number of raspberry scones and an equal number of blackberry scones.
The greatest number of bags Jason can fill = Greatest common divisor of 3
and 51.
= 17 [Since 34 = 2 x 17 , 51 = 3 x 17]
Hence, the greatest number of bags Jason can fill = 17

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
3x + 46 + 14 = 90
Now,
Simplifying.
3x + 60 = 90
Subtracting 60 on both sides.
3x = 90 - 60
3x = 30
Dividing 3 into both sides.
x = 10
Thus,
The value of x on the given figure is 10.

Answers
9514 1404 393
Answer:
y = 2(x +2)(x -4)
Step-by-step explanation:
The y-intercept will be a constant times the product of the roots. Here, the product of the roots is (-2)(4) = -8, so the constant of interest is -16/-8 = 2. That constant is the coefficient of the leading term of the quadratic, so is a multiplier of the factored form.
y = 2(x +2)(x -4)

Middleton, Colorado, hosted a youth soccer tournament. Youth soccer fields vary in size per the age of the players. The field for the nine‐ and ten‐year‐old players was 75 yards long by 45 yards wide. The field for the 11‐14‐year‐old players was proportionally larger. If the length of the field for the 11‐14‐year‐old players was 100 yards, what was the width?
Answers
Answer:
The correct answer is 60!
Step-by-step explanation:
Remember, 3/4 is 0.75.
75/100 = 3/4
45/60= 3/4
The equation explains that 75/100 is a fraction that it equal to 3/4, which is 0.75 as a decimal. 60 is the digit that is the denominator to 45, getting 3/4, or 0.75 also. So the width of the 11-14 year-old soccer field is 60 yards.
The width when the length of the field for the 11‐14‐year‐old players was 100 yards should be considered as the 60.
Calculation of the width:Since we know that 75 by 100 is three-fourth
And, 45 by 60 is also three-fourth
Also, there is field for the nine‐ and ten‐year‐old players was 75 yards long by 45 yards wide.
So based on this, The width when the length of the field for the 11‐14‐year‐old players was 100 yards should be considered as the 60.

Step-by-step explanation:
Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:
A = 25·10 = 250
