Answer:
y = 3x + 2
Step-by-step explanation:
Answer: 14.8units²
Step-by-step explanation:
The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
I saw the image that should have been posted with this word problem.
The rolls of wrapping paper is cylindrical in shape.
Roll A : length = 30 inches ; diameter = 3 inches
Roll B : length = 24 inches ; diameter = unknown
Lateral surface area = 2 π r h
Lateral Surface area of Roll A = Lateral Surface area of Roll B
2 * 3.14 * 1.5in * 30in = 2 * 3.14 * r * 24 in
282.60 in² = 150.72 in * r
282.60 in² / 150.72 in = r
1.875 in = r
diameter is 2 times the radius = 1.875 in * 2 = 3.75 inches
The diameter of Roll B is 3.75 inches.
Answer:
(12 + n/3) = 2n + 1
Step-by-step explanation:
(12 + n/3) = 2n + 1
36 + n = 6n + 3
33 = 5n
n = 33/5
