Answer:
The polygon has [tex]12[/tex] sides.
Step-by-step explanation:
Recall that the expression for finding the measure of one interior angle of a regular polygon is [tex]\frac{180(n-2)}{n}[/tex], where [tex]n[/tex] is the number of sides the polygon has (and [tex]n\neq 0[/tex]), which is what we want to find.
Because the measure of one interior angle of the given polygon is [tex]150\textdegree[/tex], we can write the following equation to solve for [tex]n[/tex]:
[tex]\frac{180(n-2)}{n}=150[/tex]
Solving for [tex]n[/tex], we get:
[tex]\frac{180(n-2)}{n}=150[/tex]
[tex]\frac{180n-360}{n}=150[/tex] (Distribute the [tex]180[/tex] in the numerator)
[tex]180n-360=150n[/tex] (Multiply both sides of the equation by [tex]n[/tex] to eliminate the denominator and simplify)
[tex]30n-360=0[/tex] (Subtract [tex]150n[/tex] from both sides of the equation and simplify)
[tex]30n=360[/tex] (Add [tex]360[/tex] to both sides of the equation to isolate [tex]n[/tex] and simplify)
[tex]\bf n=12[/tex] (Divide both sides of the equation by [tex]30[/tex] to get rid of [tex]n[/tex]'s coefficient and simplify)
Therefore, the polygon has [tex]\bf 12[/tex] sides. Hope this helps!

Answer: $1500
Step-by-step explanation:
Given information
Number of puppies = 6
Cost of each puppy = $250
Given expression deducted from the question
Total cost = number of puppies × cost of each
Substitute values into the expression
Total cost = 6 × 250
Simplify by multiplication
Total cost = [tex]\boxed{1500}[/tex]

Malcom has $638.54 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for 159.50 today. Write an inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee.
(9th grade Algebra 1)
The inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500
The given parameters:
initial amount of money in Malcom's account = $638.54
a constant balance to be maintained to avoid a fee = $500
amount to be withdrawn today = $159.50
To find:
inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a feeLet the LEAST amount = x
Here are basic things to note in order to form the equation:
The money going into the account must be addedThe amount to be withdrawn will be subtracted Finally, the total amount must be greater or equal to $500Considering the above explanation, the inequality becomes;
638.54 + x - 159.50 ≥ $500
Rearrange to match the given options;
638.54 - 159.50 + x ≥ $500
Thus, the inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500

Answer:
1. You should mix 5 cups of yellow paint with 1 cup of blue paint. The table shows that the ratio is 1:5 (blue:yellow) so 1 cup of blue paint means you need 5 cups of yellow paint.
2. Using the same ratio (1:5), you can multiply both numbers by any number and get the same shade of green.
5 cups of blue paint will need 25 cups of yellow paint.
(1 x 5 = 5 : 5 x 5 = 25)

Ms. Johnson bought an area rug for her den. The perimeter is 30 feet. The width of the rug is
2yards What is the area of Ms. Johnson's rug in square feet and square yards?
in both feet and yards.
Answer:
6 sq yards, 54 sq feet
Step-by-step explanation:
30/3 = 10, 10 - 4 = 6, 6/2 = 3, 3 * 2 = 6
30/3 since we are calculating yards(3 ft = 1 yard), 10 -4 since 2 sides have the width of 2 yards. 6/2 since there is two sides left.
Basically the same thing for sq feet.

Answer:
∠LMP = 77
∠NMP = 103
Step-by-step explanation:
to find the measure of ∠LMP and ∠NMP
we know that ∠LMN is a straight line so that will be 180 degrees
so you can say that
∠LMP + ∠NMP = 180
(-16x +13) + (-20x +23) = 180
-16x +13 -20x + 23 = 180
-36x + 36 = 180
-36x = 180-36
-36x = 144
x = 144/-36
x = -4
∠LMP = (-16x +13)
= ( -16 (-4) + 13)
= ( 64 + 13)
= 77
∠LMP = 77
∠NMP = (-20x +23)
= (-20 (-4) + 23)
= 80 + 23
= 103
∠NMP = 103

0.582 times 10 what is value of the 2
Answer:
5.82
Step-by-step explanation:
0.582 x 10
=> Shift the decimal place by 1
=> 5.82
The required simplified value of the product is 5.82 and the value of 2 in the expression is 0.01 times.
To determine the value of 2 in the product of 0.582 times 10.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Product = 10 * 0.582
Product = 5.82,
Where 2 is located at the thousandth place,
So, the value of 2 in 5.82 is 0.01 times of 2.
Thus, the required simplified value of the product is 5.82 and the value of 2 in the expression is 0.01 times.

a bank account balance for an account with an initial deposit of p dollars earns interest at an annual rate of r . the amount of money in the account after n years is described using the following expression p (1+r)n what effect if any does decreasing the value of r have on the amount of money after n years?
Answer:
Step-by-step explanation:
For the same exponent n and 1 < a < b we have
[tex]a^n < b^n[/tex]
Now if we decrease the r the value then 1 + r will also decrease.
If follows that the amount of money after n years will also decrease.
