Mathematics

The area of a garden is the amount of space the garden occupies

<em>The area of the garden is (c) 375 ft^2</em>

The given parameters are:

<em />L = 15 \times W<em> --- Length equals 15 times width</em>

Perimeter=160

The perimeter of a rectangle is:

Perimeter= 2(L + W)

Substitute known values

160= 2(15 \times W + W)

Divide through by 2

80= 15 \times W + W

80= 15W + W

80= 16W

Divide through by 16

5= W

Rewrite as:

W =5

The area of a rectangle is:

Area = L \times W

Substitute L = 15 \times W

Area = 15 \times W \times W

Substitute W =5

Area = 15 \times 5 \times 5

Area = 375

Hence, the area of the garden is <em>(c) 375 ft^2</em>

Solve the following system using elimination:
{7 x + 2 y = -19 | (equation 1)
{2 y - x = 21 | (equation 2)

Add 1/7 × (equation 1) to equation 2:
{7 x + 2 y = -19 | (equation 1)
{0 x+(16 y)/7 = 128/7 | (equation 2)

Multiply equation 2 by 7/16:
{7 x + 2 y = -19 | (equation 1)
{0 x+y = 8 | (equation 2)

Subtract 2 × (equation 2) from equation 1:
{7 x+0 y = -35 | (equation 1)
{0 x+y = 8 | (equation 2)

Divide equation 1 by 7:
{x+0 y = -5 | (equation 1)
{0 x+y = 8 | (equation 2)

Collect results:
Answer: {x = -5, y = 8

An account earns simple interest.<br><br> $1800 at 6.5% for 30 months
Vikentia [17]

A = P(1 + rt)

Where:

<span>A = Total Accrued Amount (principal + interest)
P = Principal AmountI = Interest Amount
r = Rate of Interest per year in decimal;
r = R/100
R = Rate of Interest per year as a percent;
 R = r * 100
<span>t = Time Period involved in months or years

</span></span>Calculation:

First, converting R percent to r a decimal
r = R/100 = 6.5%/100 = 0.065 per year,
putting time into years for simplicity,
30 months ÷ 12 months/year = 2.5 years,
then, solving our equation

<span>A = 1800(1 + (0.065 × 2.5)) = 2092.5 </span>
A = $ 2,092.50

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 1,800.00
at a rate of 6.5% per year
<span>for 2.5 years (30 months) is $ 2,092.50.</span>
