Answer:
length: 30 ft
width: 15 ft
Step-by-step explanation:
The sum of length and width is half the perimeter, 45 ft.
The ratio of length to width is 2 : 1, so the sum in "ratio units" is 2+1 = 3. That is, each "ratio unit" stands for 45 ft/3 = 15 ft of actual length.
Jason's pool is ...
length : width = 2·15 ft : 1·15 ft = 30 ft : 15 ft
Jason's pool is 30 ft long and 15 ft wide.
Answer:
Arc length of arc BC is 6.98 units or roughly 7 units.
Step-by-step explanation:
First recall that the formula for the circumference of a circle is C = 2πr, where r is the radius. Here the radius is 4 units. so the circumference of the (entire) circle is C = 2π(4 units) = 8π units.
The central angle for the arc shown in yellow is 100 degrees. The length of this arc is a fraction of C as found earlier:
100
------- * 8π units = 800π/360 units, or 6.98 units (about 7 units).
360
Arc length of arc BC is 6.98 units or roughly 7 units.
Answer:
12 + 12 = 24
Step-by-step explanation:
P = 2L + 2W
P = 2*16 + 2W
P = 56
56 = 32 + 2W Subtract 32 from both sides
56 - 32 = 2W
24 = 2W Divide by 2
24/2 = 2W/2
12 = W
The answer you want is 2 * 12 = 24
$75.77 × 0.25 = $18.94
The correct answer is B.
