What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

Number of members = 100

And, It contains 20 more Democrat's than Republicans.

Now, Let number of Democrat's does it contain = x

Then, Number of Republicans does it contain = x - 20

Since, Number of members = 100

Hence, We can formulate;

⇒ x + (x - 20) = 100

⇒ 2x = 100 + 20

⇒ 2x = 120

⇒ x = 60

Thus, Number of Democrat's does it contain = 60

#SPJ5
100=d+(d-20)
First add 20 to both sides.  
120=d+d
Now divide the sides by 2.
D=60
There are 60 democrats.
100=60+(60-20)
100=60+40

there are 60 democrats and 40 republicans

Investigation Circles: Investigation 2

I need help with the worksheet

Answers

Explanation:

1. In order for the idea of "perpendicular distance" to make any sense in this context, the number of sides of the polygon must be even. Then the "diameter" is the diameter of the inscribed circle. As the number of sides increases, the polygon differs less and less from a circle, so the relationship of perimeter and "diameter" becomes closer to the relationship in a circle.

"As the number of sides in a regular polygon increases, the ratio of perimeter to diameter for that polygon approaches pi."

__

2. We know from the first question that ...

circumference/diameter = π

And we know that ...

diameter = 2·radius

Then the following are true:

A. circumference = π · diameter

B. circumference = (2·radius) · π

__

3. The expressions in order evaluate to approximately ...

4.0, 3.45, 3.31, 3.24

Of these, the last is closest to pi (3.14....). The appropriate choice is ...

D. (10·5)/15.4

__

4. Pi cannot be expressed as a rational number, because pi is irrational. A number of lengthy proofs have been offered to demonstrate this fact. One of them makes use of the fact that the tangent of any rational number is irrational, and the tangent of π/4 is 1. Since 1 is a rational number, π/4 cannot be, so π cannot be expressed as a rational number.

A student bought a juice pouch for $2.50 and 3 bags of chips . The total cost was $5.05 write and solve an equation to determine the cost of a bag of chips

Answers

You have to subtract $2.50 and $5.05 then you divide that with 3 and you should get $0.85
Do 5.05 minus 2.50 and your would get 2.55 then you would divide that by 3 and you would get 85 cents per bag of chips
