Answer:
square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.

The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base. 
The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%

35x=245
so you would divide both sides by 35
x=7
so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back

Answer: it is -1
Step-by-step explanation:
5*5x=25x
5*3=15
25x+15=-10
25x= -10-15
25x= -25
X=-25/25
= -1
