Answer:

circumference = 113.09

circumference = 113.1 (simplified) (more likely the answer is simplified)

Step-by-step explanation:

So the diameter is 36 which means the radius is 18 since diameter is always double of the radius

2 * π * 18 = 2 * π * 18 = 113.0973 (113.1) (simplified)

Answer:
113.04

Explanation:
So, the formula is C=pi x d

Once you substitute in the number given the equation is now .. C= pi x 36

36 x 3.14=113.04

Therefore, the circles circumference is 113.04

2-3k because the difference between something means it is subtraction and the product of 3 and k would just be 3k since you don't know what k is.

Evaluate 3C1. a)3 b)1 c)2 d)6

murzikaleks [220]

Answer: Option a) 3

Step-by-step explanation:

The formula for calculating combinations is as follows

$nCr = \frac{n!}{r!(n-r)!}$

Where "n" is the amount of items in a set and you can choose "r" from them

3C1 reads as: The combination of 1 in 3. You have a set of 3 elements and choose 1 of them.

$n = 3\\\\r = 1$

So :

$3C1=\frac{3!}{1!(3-1)!}\\\\3C1=\frac{3!}{1!*2!}\\\\3C1=\frac{3*2*1}{1*2*1}\\\\3C1=3$

If p stays constant and u is doubled what happens to e? given U=EP

Stolb23 [73]

We are given the expression:

U = E * P

The equality symbol “ = “ means that for all cases, the value of U and E * P must always be equal. This means that whatever happens on the left side, must equally happen on the right side.

So what this actually means is that, if we double U so we must also double the expression E * P, that is:

2 U = 2 (E * P)

However since P stays constant in the process, therefore only E is changed, hence:

2 U = P * 2 E

So we can see that E is also doubled.

After 10 months the simple interest of a 6,000 investment was $769. What is the interest rate

slega [8]

Answer:

Interest rate ( r ) = 15.38% or 0.1538

Step-by-step explanation:

Given the principal (P) = $6,000, and the simple interest of $769 earned after 10 months:

We can determine the interest rate (r ) by creating its formula algebraically, then use the equation to solve for its value.

Using the simple interest formula,

I = P × r × t 

where:

I = interest amount = $769

P = present value of the principal = $6,000

r = interest rate

t = time = 10/12 (10 months out of 12 months) = 0.83333

I = P × r × t

Divide both sides by P × t:

I / ( P × t ) = P × t × r / ( P × t )

I / ( P × t ) = r

Therefore, the formula for the interest rate is: r = I / ( P × t )

Substitute the given values into the formula to solve for r:

r = I / ( P × t )

r = $769 / ($6,000 × 0.83333)

r = $769/ 4,999.99999

r = 0.1538 or 15.38%
