For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
A. sum = (180)(10) = 1800°
B. sum = (180)(8) = 1440°
C. sum = (360)(10) = 3600°
D. sum = (360)(8) = 2880°
Answers
B. sum = (180)(8) = 1440° is answer
Sum of the interior angles in the polygon can be represented in option B. sum = (180)(8) = 1440°.
What are Polygons?Polygons are closed figures which has at least three set of line segments joined together.
The polygon with least number of sides is triangle.
The equation to find the sum of the interior angles of a polygon with n sides is given by,
Sum of the interior angles = (n - 2) × 180°
Given is a polygon with 10 sides.
Substituting 10 to the equation, we get,
Sum of the interior angles = (10 - 2) × 180°
= 8 × 180°
= 1440°
This equation is represented in option B.
Hence the correct option for the sum of the interior angles of polygon with 10 sides is B. sum = (180)(8) = 1440°.

Justin has $57.18 in his checking account. He deposits his paycheck of $256.79. He then buys $68.42 in groceries, $50.00 in gas, and 2 movies for $15.58 each. What is the new balance in Justin’s checking account?
Answers
313.97 - 68.42 = 245.55
245.55 - 50.00 = 195.55
195.55 - 31.06 = 164.49
that’s your answer
Answer: 164.39
Step-by-step explanation: 57.18 + 256.79 = 313.97
313.97 - 68.42 = 245.49
245.49 - 50.00 = 195.49
195.49 - 15.58 - 15.58 = 164.39

Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answers
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x

The perimeter of the rectangle shown is 36 inches. Write and solve an equation to find the value of x
Answers
36 = 24 + 8x - 12
(take away 24 and add 12 to both sides)
24 = 8x
(divide both sides by 8)
3 = x
The value of x is 3 and the length of the rectangle is 6 inches.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
Given that the perimeter of a rectangle is 36 inches.
The perimeter of a rectangle = 2(L+W)
Here L = (4x-6) and W = 12
⇒ 36 = 2(4x-6) + 2(12)
Apply the distributive property of multiplication,
⇒ 36 = 24 + 8x - 12
Rearrange the terms and we get
⇒ 24 = 8x
Divide both sides by 8
⇒ x = 3
Therefore, the value of x is 3 and the length of the rectangle is 6 inches.

When Jaylen started high school, 1,430 students attended his school. On the day of his graduation, only 1,001 students attended his school.
The number of students who attended Jaylen's school decreased by what percent?
Answers
Answer:
The number of students decreased by 30%.
Step-by-step explanation:
Subtract 1430 from 1001, then find the absolute value.
[tex]\frac{|1001-1430|}{1430}\\\frac{|-429|}{1430}\\\frac{429}{1430}[/tex]
Simplify 429/1430 by cancelling out 143.
[tex]\frac{429/143}{1430/143}\\\frac{3}{10}[/tex]
Convert 3/10 into a percentage by multiplying it by 100.
[tex]\frac{3*100}{10}\\\frac{300}{10}\\30[/tex]
The decrease of students was 30%.
