Hmm, let's see. Well a triangle's dimensions add up to 180. If both sides given add up to 14. Simply subtract 180 by 14. You get, 166. If I'm wrong, feel free to correct me on that :)
Answer:
a. y=7(x+0.5)^2+8.25
b. y=4(x+0.75)^2+0.75
c. the equation simplified is just f
d. f(f(x))=x^4+2x^3+4^2+3x+3
Hope tis helps
Answer:
30
Step-by-step explanation:
Since the question says that it took her 45 minutes per hour, you can use that to find the distance of the route she took.
45 miles: 60 minutes
15 miles: 20 minutes ----------------cross multiply (20x45 and then divide by 60)
Therefore, if she is going to use the same route in reverse, the distance would be 15 miles.
Use the formula for speed:
speed= distance/time
= 15/0.5 ---------- 0.5 hours is the same as 30 minutes
= 30
Answer:
<h2>7.1 × 10⁸</h2>
Step-by-step explanation:
You must divide the diameter of Mars by the diameter of softball.
Ratio=number of Km / number of hours
Data:
Number of Km=5 Km
Number of hours=1 1/2 hour=1.5 hour.
Ratio=5 km/1.5 hour=3.333... km/h≈3.33 km/h.
Answer; their ratio was 3.33 Km/h.
