An empty dump truck weighs about 2.8×105 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific notation.(1 point)

Question

Generate a visually pleasing image illustrating the concept of a large, empty dump truck parked in an expansive waste management facility. The dump truck, painted in a bright hue, remains stationary, waiting to be filled with trash. Adjacent to it, there is a massive pile of garbage weighing 15,300 pounds, signified with a weight scale. All elements of the image are delineated carefully, but strictly no numerical representations or text-based information should be present.

Answer 1

To find the weight of the dump truck with the added trash, you need to add the weight of the trash to the weight of the empty dump truck.

Empty dump truck weight: 2.8×10^5 pounds
Added trash weight: 15,300 pounds

To add these two numbers, you align the decimal points and add the digits:

2.8×10^5
+ 1.53×10^4
_____________
2.953×10^5 pounds

So the weight of the dump truck with the added trash is 2.953×10^5 pounds.

Answer 2

To find the weight of the dump truck after 15,300 pounds of trash is added, we can simply add the weight of the trash to the weight of the empty dump truck.

Empty dump truck weight: 2.8×10^5 pounds
Weight of trash added: 15,300 pounds

To add these two numbers, we can use scientific notation. Since the weight of the empty dump truck is already in scientific notation, we can convert the weight of the trash added into scientific notation.

15,300 pounds can be written as 1.53×10^4 pounds.

Now we can add the weights:
2.8×10^5 pounds + 1.53×10^4 pounds = 2.953×10^5 pounds

So, the weight of the dump truck after 15,300 pounds of trash is added is 2.953×10^5 pounds.

Answer: 2.953×10^5 pounds

Answer 3

To find the weight of the dump truck after adding 15,300 pounds of trash, you need to add the weight of the trash to the empty weight of the truck.

First, let's convert the empty weight of the truck to scientific notation. The given value, 2.8×10^5 pounds, is already in scientific notation.

Next, add the weight of the trash to the empty weight of the truck:

2.8×10^5 pounds + 15,300 pounds = 2.8×10^5 + 1.53×10^4 pounds

To add these two values in scientific notation, you need to make sure that both numbers have the same exponent (power of 10). In this case, you can rewrite 15,300 pounds as 1.53×10^4 pounds.

Now, you can add the two numbers:

2.8×10^5 + 1.53×10^4 = 2.8×10^5 + 0.153×10^5

Since the exponents are the same (both are 5), you can add the coefficients:

2.8 + 0.153 = 2.953

Finally, write the result in scientific notation:

2.953×10^5 pounds.

So, the weight of the dump truck after adding 15,300 pounds of trash is 2.953×10^5 pounds.
