1) Circumference of Earth: Diameter x π → 12,800 x π = 40,212.39 km
2) time in Hour = distance/speed → distance = 40,212.39 and speed = 2 Mi/h
1st: convert miles into km : 1 mile = 1.609344 km and 2 miles = 3.218688 km
2nd: convert speed into km/h → speed = 3.218688 km/h
And time in hour = 40,212.39 / 3.218688 → time = 12,493 hours OR in days:
12,493 / 24 = 521 days (OR 104 weeks, including 2 days of rest)
Answer:
14 rides
Step-by-step explanation:
16 = 0.79x + 4.5
11.5 = 0.79x
x = 14.55 or 14
rounding down because it can't go over $16.
0.79(14) + 4.5 = $15.56
Answer:
3x² + 3x - 36=
(3x+12)(x-3)
x² - 3x - 28=
(x+4)(x-7)
Step-by-step explanation:
For both equations use the method called the "Cross Method". It is useful for these type of factorisation questions called "Trinomials".

Answer:
24 cups.
Step-by-step explanation:
18 serving requires 4 cups of Pine apple
for 108 serving, 108/18 = 6 times.
