Answer:
The total area is 3016 square inches, approximately
The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
1)
Let the number of fish sandwiches sold br represented by x
Then the number of grilled cheese sold is 2X
and the number of cheeseburgers 3(2x)
x + 2x + 3(2x) = 225
and solve
2)
Let x represent the no. of pounds of peanuts
Then x + 14 represents the no of pounds of the mixture
And
(2.25)x + (3.25)(14) = (2.65)(x + 14
and solve
3) Try on your own
plz mark me as brainliest :)
