Answer:
length is 28 meters
width is 15 meters
Step-by-step explanation:
Write out formulas and assign variables:
Width: w
Length: l = 2w - 2
Here is a diagram:
<u> 2w - 2 </u>
| | w
|_________________|
The perimeter formula for rectangle is P = 2(l +w). Substitute the perimeter and the formula for length into the formula.
P = 2(l +w)
86 = 2(2w - 2 + w) Simplify inside the brackets
86 = 2(3w - 2) Divide both sides by 2
43 = 3w - 2 Add 2 to both sides
45 = 3w Divide both sides by 3
w = 45/3 Variable on left side is standard formatting
w = 15 Width of basketball court
Substitute width into the length formula to fin length.
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28 Length of basketball court
Therefore the length is 28 meters and the width is 15 meters.
$4,000 3.2% simple interest.
S.I. = Principal * interest rate * term
S.I = 4000 * 0.032 * 4 years
S.I = 512
$4,000 2.1% interest compounded annually
A = P (1 + r/n)^nt
A = 4000 (1+0.021/1)^1*4
A = 4000 (1.021)^4
A = 4000 (1.087)
A = 4,348
Interest = 4,348 - 4000 = 348
7,500 CD 5% interest compounded quarterly
A = 7500 (1 + 0.05/4)^4*4
A = 7500 (1.0125)^16
A = 7500 (1.22)
A = 9,150
Interest = 9150 - 7500 = 1,650
Total interest = 512 + 348 + 1650 = 2,510.
Answer:

Step-by-step explanation:
Answer:
1:3
Step-by-step explanation:
3:12 is the amount of shaded circles to all circles, 8:2 is basically the same thing as 3:12 and 9:3 is the amount of shaded circles to the amount of non-shaded circles. 1:3 wouldn't work because it is not the right ratio.
