Answer: (b)

Step-by-step explanation:

Given

R is inversely proportional to A i.e

R\propto \dfrac{1}{A}\\\\R=\dfrac{C}{A}\quad [\text{C=Constant}]

when R=4,\ A=100

Insert the values to get C

\Rightarrow 4=\dfrac{C}{100}\\\\\Rightarrow C=400

When A=250

\Rightarrow R=\dfrac{400}{250}\\\\\Rightarrow R=1.6

option (b) is correct

1/3 cup of flour makes 5 dinner rolls. How many cups of flour for 1 roll? and how much flower for 36 rolls?
shtirl [24]
For one roll, you need to take that 1/3 cup and split it into 5 parts. To do this, divide by 5, which means the fraction becomes 1/15, giving you 1/15 cup flower for one roll.

36 rolls is just 36 times the one roll, which is 36/15 cups. You can divide both parts by 3 to make that 12/5 cups for 36 rolls.

Answer please, thanks.

A) The perimeter is the length around the rectangle, so it would be 2 + 5 + 2 + 5 = 14m

The area is 2m * 5m = 10m^2

b/c) You have to draw a rectangle with a perimeter of 14m, and an area that ISN'T 10m^2. You could draw a 3m by 4m rectangle which would have a perimeter of 14m and an area of 12m^2.
