From the information given, the tins are circular /cylindrical because they have a diameter.
So we need to find out the base area of each tin .
Base Area = π r²
radius here will be 25/2 = 12.5
Area = 3.14 × 12.5 ×12.5
Area = 490.6cm²
For the tray the dimensions are 600mm and 500mm which seem to allude the trays are of a regular shape such as a rectangle. Let us assume it is so.
600mm = 60cm, and 500mm = 50cm
Area = L × w
Area = 50 × 60 = 3000cm²
Each tray will fit 3000 ÷ 490.6 = 6.1
6 cake tins will fit into one tray
The answer is 50
X represents a toaster, x-20 represents a rice cooker
Use the equation 5x+3(x-20)=500
Solve for x and get 70.
A toaster is 70 but a rice cooker is 50

Step-by-step explanation:
It is given in the question that a plane can fly 725 miles per hour.
So, the plane goes 725 miles in 1 hour i.e. 60 minutes.
Now, we have to find the time the plane takes to fly 150 miles.
As the plane is flying at a constant rate, so we can use the unitary method to get the required time.
Therefore, the plane will take minutes to fly 150 miles. (Answer)
For plan A f(t)=4000t+10000
for plan B 0.01+0.02+0.04+....=0.01*(2^t-1)
at first plan A seems better because you earn 4000 on the first day but you earn 0.01 but at last plan B is better .
f(31)=4000*31+10000=134000
g(31)=0.01*(2^31-1)=21474836.47
