Suppose you have just inherited a sum of money. Let’s say you choose to invest the money. How much did you inherit? Choose an am

ount between $1000 and $100,000. Do not choose an increment of 1000. In other words, do not choose $1000, $2000, $5000, $14000, etc.
What is your interest rate? Choose a rate between 0.5% and 3%.

Step-by-step explanation:

Answer :-

→ Current in 10 Ω resistor = 4 A

→ Current in 20 Ω resistor = 2 A

→ Power of the 10 Ω resistor = 160 W

→ Power of the 20 Ω resistor = 80 W

Explanation :-

We have :-

→ 1st resistance (R₁) = 10 Ω

→ 2nd resistance (R₂) = 20 Ω

→ Total current (I) = 6 A

______________________________

The current in the 10 Ω resistor is :-

I₁ = (R₂/R₁ + R₂) × I

⇒ I₁ = (20/10 + 20) × 6

⇒ I₁ = 20/30 × 6

⇒ I₁ = 4 A

The current in the 20 Ω resistor :-

I₂ = (R₁/R₁ + R₂) × I

⇒ I₂ = (10/10 + 20) × 6

⇒ I₂ = 10/30 × 6

⇒ I₂ = 2 A

______________________________

Power of 10 Ω resistor :-

P₁ = I²₁ × R₁

⇒ P₁ = (4)² × 10

⇒ P₁ = 16 × 10

⇒ P₁ = 160 W

Power of 20 Ω resistor :-

P₂ = I²₂ × R₂

⇒ P₂ = (2)² × 20

⇒ P₂ = 4 × 20

⇒ P₂ = 80 W

Answer:

  • The investment is P = $32550
  • Interest rate is r = 2% or 0.02
  • Time is t = 5 years or t = 10 years

<u>Formula to use:</u>

  • A = P(1 + r)^t

<u>For t = 5 we get:</u>

  • A = 32550*(1 + 0.02)^5 = $35937.83

<u>For t = 10 we get:</u>

  • A = 32550*(1 + 0.02)^10 = $39678.27

Solve.<br> 3(5z + 7) = 33
Ivenika [448]

Answer:

z = 4/5

Step-by-step explanation:

3(5z + 7) = 33

Divide each side by 3

3/3(5z + 7) = 33/3

5z+7 = 11

Subtract 7 from each side

5z+7-7 = 11-7

5z = 4

Divide by 5

5z/5 = 4/5

z = 4/5

Select the points that are solutions to the system of inequalities. Select all that apply
Nana76 [90]

Answer:

(-10, 10) and (0,10).

Step-by-step explanation:

For a point to be a solution to the system of inequalities, you will need to see which of the points falls into the shaded area.

When we test out each of the points, we can see that only:

(-10, 10) and (0,10) fall into the blue-shaded area.
