A. coffee and soda consumes (55%+65)-100%=120%-100%=20%
     P1=20/100=2/10=1/5

b. does not consume at least one of these products= 100-75=25 %
   P2= 25/100=1/4

Answer:

4 quarters

10 tenths

Step-by-step explanation:

<h3>Tenths</h3>

\frac{1}{10}

<h3>Quarter</h3>

\frac{1}{4}

<h3>Whole</h3>

1

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

1 = \frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}

∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole

1 = \frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}

∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole

SUMMARY: how can you use mapping rules to find rotations of objects at 90, 180, and 270 degrees?
Levart [38]

A rotation is an isometric transformation that turns every point of a figure through a specified angle and direction about a fixed point.

To describe a rotation, you need three things:

Direction (clockwise CW or counterclockwise CCW)

Angle in degrees

Center point of rotation (turn about what point?)

The most common rotations are 180° or 90° turns, and occasionally, 270° turns, about the origin, and affect each point of a figure as follows:

A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³.
iogann1982 [59]
Volume of a Cylinder (Drum) = πr²h

Substitute the known values, 
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³

Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9

In short, Your Answer would be: $397.9

Hope this helps!
