7. A dog park covers an area of 3.49 * 10 ^ 4 yards. The community park next to it covers and area of 1.6 * 10 ^ 4 yards. What is the total number of yards in the dog park and community park combined?
C
The total area of the dog park and community park combined is calculated by adding the area of the dog park and the area of the community park together.
Area of the dog park = 3.49 * 10 ^ 4 yards
Area of the community park = 1.6 * 10 ^ 4 yards
Total area = Area of the dog park + Area of the community park
Total area = 3.49 * 10 ^ 4 + 1.6 * 10 ^ 4
Total area = (3.49 + 1.6) * 10 ^ 4
Total area = 5.09 * 10 ^ 4
Therefore, the total number of yards in the dog park and community park combined is 5.09 * 10 ^ 4 yards.
To find the total number of yards in the dog park and community park combined, you need to add the areas of both parks together.
Given:
Area of the dog park = 3.49 * 10^4 yards
Area of the community park = 1.6 * 10^4 yards
To add the areas of both parks, we can simply add the numbers in front of the exponential notation and keep the exponent the same:
3.49 * 10^4 + 1.6 * 10^4
Now, we can add the numbers in front of the exponential notation:
3.49 + 1.6 = 5.09
So, the total number of yards in the dog park and community park combined is 5.09 * 10^4 yards.
To find the total number of yards in the dog park and community park combined, you need to add the area of the dog park to the area of the community park.
The area of the dog park is given as 3.49 * 10^4 yards, and the area of the community park is given as 1.6 * 10^4 yards.
To add these two values, you can simply add the two numbers together. In this case:
3.49 * 10^4 + 1.6 * 10^4.
To add these numbers, you first need to make sure the powers of 10 are the same. In this case, they are both 10^4, so you can add the coefficients:
3.49 + 1.6 = 5.09.
Next, you write down the common power of 10:
10^4.
So the answer is 5.09 * 10^4 yards.
Therefore, the total number of yards in the dog park and community park combined is 5.09 * 10^4 yards.
