Answer: The percentage increase in perimeter is 7%.
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be
Perimeter = 2(20 + 30) = 100
The length of the rectangle is increased by 10 percent. It means that the new length would be
20 + (0.1 × 20) = 22
The width of the rectangle is increased by 5 percent. It means that the new width would be
30 + (0.05 × 30) = 31.5
The new perimeter of the rectangle would be
Perimeter = 2(22 + 31.5) = 107
The increase in perimeter is
107 - 100 = 7
The percentage increase in perimeter is
7/100 × 100 = 7%
So you have 45 and you want to add 8 more weights which are ten pounds each you multply 10 and 8 and then add 45 when
F=5.77X10^9(1.032^(y-1985)), we want to know when this is:
2.2X10^12=5.77X10^9(1.032^(y-1985))
381.2825=1.032^(y-1985)
ln(3,812825)=(y-1985)ln(1.032)
ln(3.812825)/ln(1.032)=y-1985
y=1985+ln(3.812825)/ln(1.032)
y≈2027.5
So GDP will reach 2.2 trillion during the year 2027.
Answer:
perpendicular bisector
Step-by-step explanation:
AD = DB because of their marks.
If AD = DB, then AB has a bisector of point D.
A line would form between DH to make them a perpendicular bisector.
Area of Trapezoid = (1/2)*(Sum of Parallels) * height
45 = (1/2)*(10 + 5) * h
45 = 1/2 * 15 * h
45 = 7.5 h
45 / 7.5 = h
6 = h
h = 6 Height is = 6 cm.
