4.) Determine the missing side of a rectangle with an area of 480 cm² and a length of 32 cm. Please show your work.

asambeis [7]

Answer:

w = 15 cm

Step-by-step explanation:

We want to find the width, as the area of a rectangle is length (l) * width (w).

Since we know the area and the length, we have 480 = 32w

Isolating w by dividing both sides by 32 gives us w = 15 cm

Question 10 (3 points)

Zinaida [17]

Answer:

$3,090.64

Step-by-step explanation:

We shall allocate a random letter to each value, with that I explain the formula.

Initial value of investment = $5,003.86 = P

Rate of interest = 3.7% = R

Compounding interval in a year = 365 = I

Total period = 13 years = T

Value of investment in compound interest formula shall be:

$= P \times (1 + \frac{R}{(I})^{(I \times T)}$

Now, putting values in the above equation:

$= 5,003.86 \times (1 + \frac{0.037}{365}) ^{(365\times13)}$

= $8,094.50

Thus, interest earned = Total value of investment on maturity - Initially invested amount

= $8,094.50 - $5,003.86 = $3,090.64
