Use the graph to answer the question.
The vertical axis on the left is labeled CO2 ppm and ranges from 250 to 390 in increments of 20. The vertical axis on the right is labeled temperature and ranges from 13.5 to 14.5 in increments of 0.2. The horizontal axis is labeled year and lists dates from 1000 to 2000 in increments of 100. The graph is a line fluctuating between 270 and 305 from left to right. The line slopes upward near the right end toward the upper right corner.

A skyscraper has a mass of 2.2×105 tons. Another skyscraper in the same town has a mass of 3.7×105 tons. What is the combined mass, in tons, of the two skyscrapers? Use scientific notation to express your answer to 1 decimal place.
To find the combined mass of the two skyscrapers, you need to add their masses together.
2.2 × 10^5 tons + 3.7 × 10^5 tons = 5.9 × 10^5 tons
Therefore, the combined mass of the two skyscrapers is 5.9 × 10^5 tons.
A certain insect is approximately 4×10−2 inches long. A second insect is about 1.3×10−1 inches long. What is the total length of the two insects in inches? Use scientific notation to express your answer to 1 decimal place.
To find the total length of the two insects, you need to add their lengths together.
4 × 10^-2 inches + 1.3 × 10^-1 inches = 1.7 × 10^-1 inches
Therefore, the total length of the two insects is 1.7 × 10^-1 inches.
What is the sum of 6.3×103 and 2.41×104? Use scientific notation to express your answer.
To find the sum of 6.3×10^3 and 2.41×10^4, you simply add the numbers together.
6.3×10^3 + 2.41×10^4 = 2.41×10^4 + 6.3×10^3
To add these numbers, we need to align the powers of 10:
2.41×10^4 + 6.3×10^3 = 2.41×10^4 + 0.63×10^4
Now we can add the numbers:
2.41×10^4 + 0.63×10^4 = 3.04×10^4
Therefore, the sum of 6.3×10^3 and 2.41×10^4 is 3.04×10^4.
An American football field has an area of 6.4×103 square yards. A Canadian football field is 3,350 square yards larger. What is the area of a Canadian football field? Write your answer in scientific notation to 2 decimal places.
To find the area of the Canadian football field, we need to add the additional 3,350 square yards to the area of the American football field.
6.4×10^3 square yards + 3,350 square yards = 6.4×10^3 square yards + 3.35×10^3 square yards
Now we can add the numbers:
6.4×10^3 square yards + 3.35×10^3 square yards = 9.75×10^3 square yards
Therefore, the area of the Canadian football field is 9.75×10^3 square yards.
A human hair has a diameter of about 4×10−3 inches. A fingernail is about 0.011 inches thicker. How thick is a fingernail? Write your answer as a decimal to 3 places.
To find the thickness of a fingernail, we need to add the thickness of the hair (4×10^-3 inches) and the additional thickness of 0.011 inches.
4×10^-3 inches + 0.011 inches = 0.015 inches
Therefore, the fingernail is approximately 0.015 inches thick.
Add 7.3×107+1.8×107. Which is the correct sum?
9.1+10^7
9.1×10^14
8.1×10^7
9.1×10^7
To add 7.3×10^7 and 1.8×10^7, we simply add the numbers together.
7.3×10^7 + 1.8×10^7 = 9.1×10^7
Therefore, the correct sum is 9.1×10^7.
The population of a city is given as 3.45×106. A nearby city has a population of 1.3×105. What is the sum of the populations of the two cities in scientific notation?
35.8+10^5
4.75×10^11
3.58×10^6
4.75×10^5
To find the sum of the populations of the two cities, we simply add the numbers together.
3.45×10^6 + 1.3×10^5 = 3.58×10^6
Therefore, the sum of the populations of the two cities in scientific notation is 3.58×10^6.
An empty dump truck weighs about 2.8×10^5 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific notation.
4.33×10^5 pounds
15,302.8 pounds
29,530 pounds
2.953×10^5 pounds
To find the weight of the dump truck after adding 15,300 pounds of trash, we need to add the weight of the empty dump truck (2.8×10^5 pounds) and the weight of the trash (15,300 pounds).
2.8×10^5 pounds + 15,300 pounds = 2.953×10^5 pounds
Therefore, the weight of the dump truck after adding 15,300 pounds of trash is approximately 2.953×10^5 pounds.
The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463×10^11 years longer. What is the half-life of uranium-238? The answer should be in decimal form.
447,000,000,000
4.4637×10^11
11,463,000,000
516,300,000,000
To find the half-life of uranium-238, we need to add the additional 4.463×10^11 years to the half-life of uranium-235 (700,000,000 years).
700,000,000 years + 4.463×10^11 years = 4.4637×10^11 years
Therefore, the half-life of uranium-238 is approximately 4.4637×10^11 years.
A mobile phone holds 1.28×1011 bytes of storage. You can also pay more money to get an additional 384,000,000,000 bytes. How much storage would your phone have if you buy the additional bytes? The answer should be in scientific notation.
5.12×10^11
385.28×10^11
385,280,000,000
5.12×10^9
To find the total storage of the phone after buying the additional bytes, we need to add the current storage (1.28×10^11 bytes) to the additional storage (384,000,000,000 bytes).
1.28×10^11 bytes + 384,000,000,000 bytes = 5.12×10^11 bytes
Therefore, the phone's storage would be 5.12×10^11 bytes if you buy the additional bytes.
