Answer:

a, c, and d

Step-by-step explanation:

when you add up the angles of the triangle, you get 180, 150, 180, 90, and then 175. 150 degrees and 175 degrees are not valid triangles.

1/2x - 4 = 1/3x + 5

Mamont248 [21]

Answer:

X = 54

Step-by-step explanation:

Let's solve your equation step-by-step.

1/2x−4=1/3x+5

Step 1: Subtract 1/3x from both sides.

1/2x−4−1/3x=1/3x+5−1/3x

1/6x−4=5

Step 2: Add 4 to both sides.

1/6x−4+4=5+4

1/6x=9

Step 3: Multiply both sides by 6.

6*(1/6x)=(6)*(9)

x=54

Maria has a portfolio consisting of 7 shares of stock A (purchased for $70 per share) and 4 shares of stock B (purchased for $10

Vlad [161]

Answer:

Hence, the expected rate of return after 1 year for Mary's portfolio is $0.17751$

Step-by-step explanation:

We have,

Purchase 7 shares of stock A for $70 per share and 4 shares of stock B for $100 per share then The expected rate of return after 1 year for Mary's portfolio.

Weight invested in stock A is $W_x=\frac{7\times 70}{7\times 70+4\times 100}$

$\Rightarrow W_x=\frac{490}{490+400}\\\Rightarrow W_x=\frac{490}{890}\\\Rightarrow W_x=\frac{49}{89}\\\Rightarrow W_x=0.5505$

Weight invested in stock B is $W_y=\frac{4\times 100}{7\times 70+4\times 100}$

$\Rightarrow W_y=\frac{400}{490+400} \\\Rightarrow W_y=\frac{400}{890} \\\Rightarrow W_y=\frac{40}{89} \\\Rightarrow W_y=0.4494$

The expected value of the rate of return $=W_x\times\;\text{expected rates of stock A}+W_y\times\;\text{expected rates of stock B}$

$=0.5505\times0.02+0.4494\times0.15$

$=0.01101+0.06741$

$=0.17751$
