D is distance which is 72 meters
time represents seconds which is 12
so ratio is 12:72
reduce to get 1:6
time over distance would be 1/6
every second Eddie runs 6 meters
so t= d/6
or 6t=d
Given:
Joey had 26 game cards.
His friend Richard gave him some more, and now Joey has 100 cards.
To find:
How many cards did Richard give to Joey?
Solution:
Let x be the number of cards that Richard give to Joey.
Joey had 26 game cards.
Now, the total cards joey has 
Joey has total 100 cards.
Therefore, Richard gave him 74 cards.
D+8=X
X-2=K
K+C
i hope that answers your question but you were not specific on telling me what to do.
Answer:
Step-by-step explanation:
Air pressure is measured in pascals. For a professional American football game, the ball should be inflated to about 90,000 pascals. Scientists studied the effects of air temperature on the pressure inside American footballs by taking these steps:
1. Prepare 100 footballs.
2. Measure each football's air pressure.
3. Divide footballs into 10 groups.
4. Place the groups in different lockers cooled to different air temperatures.
5. After 12 hours, remove the footballs from lockers.
6. Measure each football’s pressure again.
7. Compare the new pressures to the starting pressures.
What two terms best describe the variable "air pressure inside the football" in this experiment?
independent, qualitative
independent, quantitative
dependent, qualitative
dependent, quantitative
Answer:
y=x^4 is a function
Explanation:
A function is defined as given an equation, there should be only one corresponding, y value for any x value. In the table from the picture you attached, it is shown as for each x value, there is one corresponding y value. Therefore, x^4 is a function.
