Answer:
Independent
Step-by-step explanation:
Answer: A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
<span>for the first part, realize that the hour and minute hands are moving at different rates; in one hour, the minute hands moves all the way around the face of the clock, and thus moves a total of 360 degrees or 2 pi radians; the hour hand moves only 1/12 away around the clock, so covers only 30 degrees or Pi/6 radians.
Now, the LINEAR distance traveled by the tip of each hand is also determined by the length of the hand. In the case of the minute hand, it sweeps out a circle of radius 10 cm, so traces out a circle of radius 10 cm. Since the circumference of a circle is 2*pi*r, the minute hand (remember it made one complete cycle) covers a distance of 2*pi*10cm=20 Pi cm
The hour hand covers only 1/12 a circle, but that circle is only 6 cm in radius, so the distance traveled by the tip of the minute hand is:
1/12 *[2 *pi*r]=1/12*[12*pi]=pi
so the difference is 19pi
for the last part, you should draw a diagram of the two hands, the minute hand is 10 cm in length, the hour hand is 6 cm in length, and they are 30 degrees apart...from that drawing, see if you can figure out the remaining leg of the triangle you can form from them
good luck</span><span>

QUESTION A
The total number of bottles Ella collected is
The number of bottles that are plastic is
The percentage of bottles that are plastic is
Therefore 38% of the bottles are plastic.
QUESTION B
The total number of bottles that are glass is
The total number of bottles Ella collected is
The percentage of bottles that is glass is
Therefore 62% of the bottles are glass
Answer:
13
Step-by-step explanation:
We want to find 65% of 20
65% *20
Changing to decimal form
.65 *20
13
