Mr. Smith borrowed $22,000 to purchase stock for his baseball card shop. He repaid the simple interest loan after four years. He
Stella [2.4K]

Based on the calculations, the interest rate on the stock in four (4) years is equal to 7.1%.

<u>Given the following data:</u>

Amount borrowed (Principal) = $22,000.

Simple interest, I = $78.40.

Time = 4 year.

To determine the interest rate on the stock in four (4) years:

<h3>How to calculate simple interest?</h3>

Mathematically, simple interest can be calculated by using this formula:

I = PRT

<u>Where:</u>

  • S.I is the simple interest.
  • P is the principal or starting amount.
  • R is the interest rate.
  • T is the time measured in years.

Making R the subject of formula, we have:

R = I/PT

Substituting the given parameters into the formula, we have;

R = 6260/(22,000 × 4)

R = 6260/(88,000)

Interest rate = 0.071 = 7.1%.

jarptica [38.1K]

Answer:

  • (4/3)⁹⁸ units²

Step-by-step explanation:

  • <em>Regular hexagons have a property that cutting off the triangles obtained by joining the midpoints of consecutive sides leaves a hexagon of 3/4 of the area.</em>

This means the area of each hexagon inside out starting from the one with unit area is 4/3 of the previous one.

  • 99 ⇒ 1
  • 98 ⇒ 1*4/3
  • 97 ⇒ 1*(4/3)²
  • ...
  • 1 ⇒ (4/3)⁹⁹⁻¹

<u>The original hexagon has the area of:</u>

  • (4/3)⁹⁸ units²
