the formula of ONE INTERIOR ANGLE of a REGULAR polygon.
Answer:
180° - (360/n)°, where n is the number of sides of the polygon.
Step-by-step explanation:
Polygon has n sides.
Divide the polygon radially into n congruent, isosceles triangles.
For each triangle:
vertex angle = (360/n)°
sum of base angles = 180° - vertex angle = 180° - (360/n)°
Each interior angle of the n-gon = 180° - (360/n)°

Consider the expression 40+24 Find the greatest common factor of the two numbers and rewrite the expression using the distributive property
Answer:
Greatest Common Factor of 40+24 is 8
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)
Step-by-step explanation:
We need to F=find the greatest common factor of the two numbers 40+24 and rewrite the expression using the distributive property
Greatest Common Factor:The greatest number that is divisible by both numbers is known as greatest common factor.
So, Greatest Common Factor of 40+24 is 8
Now, Taking 8 common we get: 8(5+3)
Distributive property:It is written as: a(b+c) = ab+ac
So, we have 8(5+3) =8(5)+8(3)
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)

Solve the Equation:
x=5 2/3=9
Answer:
sorry cnat help ya!
Step-by-step explanation:
Jack and Jill both start at point A. They each walk in a straight line at an angle of 105° to each other. After 45 minutes Jack has walked 4.5km and Jill has walked 6km. How far apart are they? Round to the nearest hundredth.
Answer: The distance between them is 8.38 km
Step-by-step explanation:
Let's suppose both of them start at the point (0km, 0km), and that Jack walks along the positive x-axis, then Jill walks at an angle of 105° measured from the positive x-axis.
After 45 minutes, jack has walked 4.5km, then if his initial position was (0 km, 0 km)
Then his new position will be (4.5km, 0km)
Jill has walked 6km, but we need to write this in rectangular components.
We can think in this as a triangle rectangle, then the components will be:
x-component = 6 km*cos(105°) = -1.55 km
y-component = 6km*sin(105°) = 5.80 km
Then the new position of Jill is ( -1.55km, 5.80km)
Now, we know that the distance between two points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
Then the distance between Jill and Jack will be equal to the distance between ( -1.55km, 5.80km) and (4.5km, 0km)
This is:
Distance = √( (-1.55km - 4.5km)^2 + (5.80km - 0km)^2)
Distance = 8.38 km
This means that they are 8.38km apart.
About how many years will it take for $8500 to reach $12,000 at a simple interest rate of 3.5%
Answer:12
Step-by-step explanation:
8500 x 35% = 297.50 in simple interest per year
12000 - 8500 = 3500 in interest earned in total
3500/297.5 = 11.76 number of years to make total interest from amount per year.
If you round up, almost 12 years .

Given the function f(x) = 0.5 |x– 4| – 3, for what values of x is f(x) =7
O x = -24, x = 16
O x= -16, x = 24
O x= -1, x = 9
O x= 1, x= -9
Answer:
-16,24 B
Step-by-step explanation:
To solve this simplify the equation until it's just the absolute value brackets
7=.5 |x-4|-3
Add 3 to both sides and divide by .5 to get
20=|x-4|
Then solve this equation where the leftmost side is a positive and then a negative
So 20=x-4
x=24
24 is one of our answers
Then solve it when the left side is a negative
-20=x-4
x=-16 which is the other answer

A bank is offering 3.5% simple interest on a savings account. If you deposit
$7,500, how much interest will you earn in 2 years?
Answer: $525
Step-by-step explanation:
The formula for Simple interest is calculated as PRT where
P = Principal = $7500
R = Rate = 3.5%
T = Time = 2 years
Interest = PRT
= 7500 × 3.5% × 2
= 7500 × 0.035 × 2
= $525

Answer:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }
Step-by-step explanation:
Given the set B
B={ 0,1,4,9,16,25}
Let us check the elements in set B.
[tex]x = 0 = 0^{2}[/tex]
[tex]x\:=\:1\:=\:1^2[/tex]
[tex]x\:=\:4\:=\:2^2[/tex]
[tex]x\:=\:9\:=\:3^2[/tex]
[tex]x\:=\:16\:=\:4^2[/tex]
[tex]x\:=\:25\:=\:5^2[/tex]
It is clear that each element in set B is a square of a whole number.
Thus, we can specify set of B by giving a written description of Its element in a variety of ways, such as:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }

Answer:
Bargain Busters shop sells the cheapest soup
Step-by-step explanation:
Bargain Busters sell 4 cans of soup for £3.76
Bargain Busters sell 1 cans of soup for
3.76÷4
=0.94
cost cutters sell 3 cans of soup for £2.85
cost cutters sell 1 cans of soup for 2.85÷3
=0.95
so
Bargain Busters<cost cutters
0.94<0.95
therefore
Bargain Busters shop sells the cheapest soup
