Answer:
<em>80.7 ft/sec</em>
Step-by-step explanation:
You need two conversion factors:
1 mile = 5280 ft, so (52780 ft)/(1 mile) = 1
1 hour = 3600 seconds, so (1 hour)/(3600 seconds) = 1
55 mi/hour * (5280 ft)/(1 mile) * (1 hour)/(3600 seconds) = 80.6666... ft/sec
Answer: 80.7 ft/sec
When two variables have a positive linear correlation, the dependent variable increases as the independent variable increases. So when the independent variable decreases, the dependent variable decreases as well. Both variables decrease and increase simultaneously.

what grade u in
Jenna has $43 and Heidi has $17.
Step-by-step explanation:
Total amount = $60
Let,
Amount of Jenna = x
Amount of Heidi = y
According to given statement;
x+y=60 Eqn 1
x=2y+9 Eqn 2
Putting value of Eqn 2 in Eqn 1;
Dividing both sides by 3,
Putting y=17 in Eqn 2
Jenna has $43 and Heidi has $17.

Let the number of days needed be x.
First day = 4 miles = 3.5 + 0.5
Second day = 3.5 + 0.5(2)
Third day = 3.5 + 0.5(3)
Equation: 3.5 + 0.5x
<u>Find the number of days needed to run 8 miles:</u>
3.5 + 0.5x = 8
0.5x = 4.5
x = 9
Answer: Casandra 8 miles on the <u>9th day</u>.
