To find the total area of the two parks combined, we need to add the areas of the dog park and the community park.
The area of the dog park is given as 3.49x10^4 yards.
The area of the community park is given as 1.6x10^4 yards.
To add these areas, we simply add the numbers in front of the powers of 10 separately:
3.49 + 1.6 = 5.09
Since both areas are measured in yards, we keep the units constant.
Therefore, the total area of the dog park and community park combined is 5.09x10^4 yards.

To find the distance from Earth to the Sun, we need to subtract the distance from Mercury to the Sun (35,000,000 miles) from the distance from Earth to the Sun (5.8x10^7 miles).
5.8x10^7 miles - 35,000,000 miles = 2.3x10^7 miles
Therefore, the distance from Earth to the Sun is approximately 2.3x10^7 miles.
5.8x10^7 miles - 35,000,000 miles = 2.3x10^7 miles
Therefore, the distance from Earth to the Sun is approximately 2.3x10^7 miles.

To subtract these numbers, we need to make sure that they have the same exponent.
5.3x10^-3 - 6.7x10^-6 can be rewritten as:
5.3x10^-3 - 0.0067x10^-3
Now, we can subtract them:
5.3 - 0.0067 = 5.2933
To express the answer in scientific notation and round to 2 decimal places, we can write it as:
5.29x10^-3
5.3x10^-3 - 6.7x10^-6 can be rewritten as:
5.3x10^-3 - 0.0067x10^-3

To calculate how much heavier an elephant is than a cat, we need to subtract the average weight of a cat from the average weight of an elephant.
1.15x10^4 pounds - 14 pounds = 1.15x10^4 pounds
Therefore, an elephant is 1.15x10^4 pounds heavier than a cat.
1.15x10^4 pounds - 14 pounds = 1.15x10^4 pounds
Therefore, an elephant is 1.15x10^4 pounds heavier than a cat.

To find out how many miles light travels in a month, we need to multiply the rate of light by the number of seconds in a month.
Rate of light: 1.9x10^5 mi/sec
Number of seconds in a month: 2.6x10^6 sec
Multiplying these two numbers:
(1.9x10^5 mi/sec) * (2.6x10^6 sec) = 4.94x10^11 mi
Therefore, light travels approximately 4.94x10^11 miles in a month.

To find out how many hours it will take for the asteroid to hit Mercury, we need to divide the distance between Mercury and the asteroid by the rate at which the asteroid is moving.
Distance to Mercury: 6.622x10^8 miles
Rate of asteroid: 15.4x10^4 mi/hr
Dividing these two numbers:
(6.622x10^8 miles) / (15.4x10^4 mi/hr) = 4.30x10^4 hours
Therefore, it will take approximately 4.30x10^4 hours for the asteroid to hit Mercury.

The display on Joaquin's calculator, showing 2.67E11, represents the number in scientific notation. E in this context represents "times 10 raised to the power of."
So, 2.67E11 can be interpreted as 2.67 multiplied by 10 raised to the power of 11.
In standard notation, this would be written as:
2.67 * 10^11
which is equal to:
267,000,000,000
Therefore, 2.67E11 is equivalent to 267 billion.
