<span>Perimeter of a rectangle: 2(l + w)
</span>
2(l + w) ≥ 30 in
<span>
Simplify- divide both sides by 2.
l + w ≥ 15 in
Substitute (w + 3) into l so only 1 variable is used.
(w + 3) + w ≥ 15 in
Simplify further- add variables and subtract 3 from both sides.
2w ≥ 12 in
Divide both sides by 2.
w ≥ 6 in

Answer:
14
Step-by-step explanation:
14/14=1
56/14=4
Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence
Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:
[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2
Answer:
$25.80
Step-by-step explanation:
First find the price of the meal with sales tax. Multiply 6.75% by $72.50.
72.50 * 0.0675 = 4.89
Add this value onto 72.50.
72.50 + 4.89 = 77.39
Divide this amount by 3.
77.39 / 3 = 25.7966...
Round this to the nearest hundredth because we're dealing with money.
$25.80 is how much each person should pay.
