Percent change=(change/original) tiimes 100
change= |original-new|
so
12 to 36
|12-36|=|-24|=24
so
pcercent change=100 times (24/12)=100 times 2=200%
50 to 35
|50-35|=|15|=15
percent change=100 times (15/50)=100 times 100 times 0.30=30%
10 to 24
|10-24|=|-14|=14
percent change=100 times (14/10)=100 times 1.4=140%
16 to 44.2
|16-44.2|=|-28.2|=28.2
percent change=100 times (28.2/16)= 100 times 1.7625=176.25%
answers are
-12 inches to 36 inches: 200%
-50 punds to 35 pounds: 30%
-10 gallons to 24 gallons: 140%
-16 centimeters to 44.2 centimeters: 176.25%
Area = (39x18)/2 =351
answer = 351 m^2
Steps:
First we cross multiply
Then Distribute,
Then move all terms to one side
Factor
Set each factor equal to zero
Answer:
65.03square units.
Step-by-step explanation:
Find the diagram in the attachment below.
Area of the sector HJK = theta/360° × πr²
theta is the angle subtended by the sector = ∠HJK = 92°
r is the radius = HJ = 9units.
Substituting the given values in the formula:
Area of sector HJK = 92°/360° × π(9)²
Area of sector HJK = 23,399.28/360
Area of sector HJK = 65.03 square units to nearest hundredth
Answer: Approximately 52.87 cm.
Step-by-step explanation:
Circumference is diameter times pie to divide the circumference by pie.
166/3.14 use 3.14 as an approximation for pie.
166/3.14 = 52.87 rounded to the nearest hundredth
