1 kilogram equals 100000 centigrams
Therefore, 2.5 kilograms equals 2.5 times 100000, which is equal to 250000 centigrams
Answer:
The rule for the linear function will be:

Step-by-step explanation:
We know that linear function can be represented using the slope-intercept formula
y = mx+b
where m is the slope and b is the y-intercept
Given the function is linear
Taking two points from the table to determine the slope




Using the point-slope form of the line equation

where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -2 and the point (1, 3)



adding 3 to both sides


or

Therefore, the rule for the linear function will be:

Step-by-step explanation:
a)<PTR=90°(angles in a semicircle)
<RPT=50°
<PRT + <PTR + <RPT=180°(angles in a triangle)
<PRT=180-(90+50)
<PRT=40°
b)From ∆QTS
<TQS = <RTP =50°
<QTS=180-(50+28)
<QTS=102°
c)<QTR=180-(90+50)
<QTR=40°

Area is (1/2) * base * height, here
Area = (1/2) (21) (18) = 9*21 = 189
Answer: 189 sq yds
