Answer:

The parabola in a coordinate plane can be thought of as a set of points P, with coordinates (x, y), such that the distances to a given point and a given line (that does not contain that point) are equal. The given point is called the focus and the line is called the directrix.

If 1800ml of a juice drink is 15% grape juice, how much grape juice should be added to make a drink that is 20% grape juice?

Svetach [21]

Answer:

112.5 mL

Step-by-step explanation:

Let x represent the amount of grape juice to add. Then the total amount of grape juice in the mix is ...

0.15(1800) +x = 0.20(1800+x)

270 +x = 360 + 0.2x . . . . . . eliminate parentheses

0.8x = 90 . . . . . . . . . . . . . . . subtract 270+0.2x

x = 90/0.8 = 112.5 . . . . . . . . divide by the coefficient of x

112 mL of grape juice should be added to make a mix that is 20% grape juice.

Find the surface area of the rectangle prism. 3cm 9cm and 6cm

lisabon 2012 [21]

Answer:

198 cm²

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

= 2(99)

= 198 cm²

Therefore, the area of the rectangular prism is 198 cm²
