The expression 1.08s + 1.02b1.08s+1.02b predicts the end-of-year value of a financial portfolio where ss is the value of stocks
Marysya12 [62]

Answer:

$22350 is the predicted value of portfolio.

Step-by-step explanation:

The given expression is 1.08s + 1.02b1.08s + 1.02b which predicts the end of year value of a financial portfolio.Here s = value of stocks and b = value of bonds.

Now we have to calculate the value of a portfolio with s = $200 and b = $100

So we will put the values of s and b in the given expression to calculate the value portfolio.

1.08×200 +1.02×(100)×1.08×(200)+ 1.02×(100) = 216 + 22032 + 102

= $22350

The predicted end to end year value of portfolio is = $22350

What is the difference of the fractions? Use the number line to help find the answer
alisha [4.7K]

Answer:

-7/10

Explanation:

Given the expression

\frac{1}{2}-1\frac{1}{5}

We can rewrite the expression as:

\frac{1}{2}-\frac{6}{5}=\frac{5}{10}-\frac{12}{10}

The number line showing the location of the two numbers is attached below. Therefore:

\frac{5}{10}-\frac{12}{10}=-\frac{7}{10}

What reason can you give for the fact that if two angles are congruent then their
timama [110]

Answer:

Explained below

Step-by-step explanation:

If two angles are congruent, it means that they have the same angle whether in degrees or radians.

Now, angles are said to be congruent so as long as the measure of the angles are the same and regardless of them point in the same or different directions.

They must not necessarily be made with lines having the same length.

For example, in the diagram of the 2 triangles I've attached, angle C and Z are congruent, and they are both marked accordingly by one short curved line. Similarly angle A and B are congruent and they are both marked accordingly by two short lines.
