30 feet.
Split into 1/4 feet segments of rope.
We can convert 30 to inches and then divide by 3:
12/4=3 (that is a quarter of a foot)
12*30= 360
360/3= 120
There are 120 pieces of quarter foot rope.
You could also say for every 1 foot, there are 4 quarters.
30*4= 120 <== same answer
I hope this helps!

Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 and 13 by 15 and 2 triangles with legs 5 inches and 12 inches.
The correct net is net a.
Surface area = sum of areas of the three rectangles and sum of the two triangles.
SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.
Answer:
20
Step-by-step explanation:
Plugin x = 10 and y = 5 in the expression.
x + 2y = 10 + 2*5
= 10 + 10
= 20

If the radius goes through 1 rotation. The "angle" gone through is 360 degrees. So the method is to figure out circumference of the circle, multiply this by a fraction involving 120, and you are done.
Formula
Arc Length = (120/360) * 2 * pi * r Substitute values into this equation.
Givens
Central angle = 120
r = 9.5
Solution
Arc Length = (120/360) * 2 * 3.14 * 9.5
Arc Length = (0.333) * 2 * 3.14 * 9.5
Arc Length = 19.87 cm
The sweaters sale price would be 20. Since the sweater normally cost $50, and it’s 30% , it’s taking 30 away from the 50 which is : 50-30= 20
