To answer this item, we let x be the number that is not unknown in this item such that the situation in this problem can be expressed as follows,
x - 9.3 = 68.91
Adding 9.3 to both sides of the equation,
x - 9.3 + 9.3 = 68.91 + 9.3
Simplifying,
x = 78.21
The answer to this item is 78.21, this I think is the first choice except that it is mistakenly written as 7.21 only.
They are larger planets, therefore they have larger cores that can give out more heat.
Answer:
energy required = 553772 kJ
Explanation:
we know that
1 m = 100 cm
1 m³ = 1000 L
so volume will be
water volume = 1,658 ×
m³
water volume = 1.658 m³
so water volume we can say = 1,658 liters of water
and
we know that 1 mg of water require = 334 J energy
so here here we can say 1 L = 334 kJ energy
as that 1658 L energy require = 1658 × 334 kJ
energy required = 553772 kJ
Regions near the equator are much warmer than regions that are further from the equator
average temps around the equator are 25°C
The answer is “D” A volcano was nearby at one time
