The standard form of the equation that represents the number of quarters, q, and the number of dimes, d, that austin has in his
pickupchik [31]
5q + 2d = 270
The intercepts can be calculated by first putting d equal to 0 and then q equal to 0. These will be:
5q = 270
q = 54; (0 , 54)
2d = 270
d = 135; (135, 0)
The equation represents the total number of coins in the piggy bank and (0 , 54) shows the number of quarters in the piggy bank when there are no dimes and (0 , 135) shows the number of dimes when there are no quarters.

A hollow toy, with the dimensions shown in the figure, is to be stuffed with rigid foam. What is the maximum amount of foam that
elena-s [515]
I saw the figure that should have accompanied this problem. It looks like an ice cream cone. A cone and a half sphere.

The height of the cone is 12 inches, its diameter is 4 inches.
The half sphere has a diameter of 4 inches.

Volume of a cone = π r² h/3 = 3.14 * (2in)² * 12in/3 = 3.14 * 4in² * 4in = 50.24in³

Volume of a sphere = 4/3 π r³ = 4/3 * 3.14 * (2in)³ = 4/3 * 3.14 * 8in³ = 33.49in³
Volume of the half sphere = 33.49in³/2 = 16.75in³

Total volume = 50.24in³ + 16.75in³ = 66.99 in³  or B.) 67.02 CUBIC INCHES
