Answer:

468.75 square inches

Step-by-step explanation:

Let the length of Julian's tank be x

Let the width of Julian's tank be y

So, Area of Julian's tank=Length \times Width =xy

Since we are given that Julian's tank is approximately 300 square inches

So, xy=300  --1

Now we are given that  The dimensions of his friend's tank are each exactly1\frac{1}{4} =\frac{5}{4}times the dimensions of Julian's tank.

So,length of his friend's tank =\frac{5}{4}x

So,width of his friend's tank =\frac{5}{4}y

So, Area of his friend's tank=\frac{5}{4}x \times \frac{5}{4}y

                                             =\frac{25}{16}xy

                                             =\frac{25}{16}(300) (Using 1)

                                             =468.75

Hence the approximate area of the rectangular base of his friend's tank is 468.75 square inches.

So, Option D is correct.

A gym teacher has $250 to spend on volleyball equipment. She buys 4 volleyball nets for $28 each. Volleyball cost $7 each. How m
Sonbull [250]
First find out how much the 4 volleyball nets are by using 4*28 which would equal to 112. Now subtract 112 from 250 and that leaves you with 138. Then you divide 138 by 7 which will give you about 19.7 which you need to take all decimals out since it isn’t an whole number. The gym teacher can only buy 19 volleyballs.

The figure below shows a right rectangular prism whose base is a square.
xxTIMURxx [149]

Answer:

The intersection of the horizontal plane with the prism would have a square shape.

Step-by-step explanation:

A right rectangular prism is one in which each side makes an angle of 90^{0} with its base, which is a square. It is a three dimensional figure with six faces.

The point where the horizontal plane and the prism coincides would take the shape of the base of the prism. This is because the prism rests with its base on the horizontal plane. Thus, the shape required is in the form of a square since its base is a square. The length and width of its base are equal.
