A) What is the radius of a circle that has an approximate circumference of 81.64 meters?

Mathematics
1 answer:
Alexxandr [17]3 years ago
8 0
For B, the equation for circumference is pi multiplied by diameter. So, 10 * 2 = 20, and 20*3.14 is 62.8 cm

For C, assuming that "approximate" means that they used 3.14 for pi, then 81.64 / 3.14 = 26, and 26 / 2 = 13 cm

Susan's investment portfolio currently contains three stocks that have a total value equal to $100,000. The beta of this portfol
Sladkaya [172]
A stock portfolio's overall beta is found by multiplying each stock's beta times the percentage of the overall portfolio it makes up and adding these terms together. Since the current portfolio's beta is known, we can treat all the stocks in the portfolio as a single stock for calculating its weight in the new portfolio. Thus, our new portfolio will have a value of $150,000, $100,000, or 2/3, of which has a beta of 1.5 and $50,000, or 1/3, of which has a beta of 3. Then the beta of the new portfolio will be 1.5*(2/3) + 3*(1/3) = 2.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of b for which the expression x² + bx + 18 can be factored is 9.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of b for which the given expression x² + bx + 18 can be factored is 9. This will make the expression factored as (x+3) and (x+6).

Thus, the value of b for which the expression x² + bx + 18 can be factored is 9.

Hal earns n dollars per hour. Next month he
xenn [34]

Answer:

Total = 1.02n

Step-by-step explanation:

Given

Earnings = n

Raise = 2\% --- <em>not 296</em>

Total = n + 0.02n

Required

Simplify the expression for total earning

The total amount is derived from:

Total = Earnings + Raise * Earnings

Total = n + 2\% * n

Express percentage as decimal

Total = n + 0.02 * n

Now, we can solve further:

Total = n + 0.02n

Total = 1.02n

<em>Hence, the simplified expression is 1.02n</em>
