Answer:
Carbon Dioxide (CO2) is a chemical compound consisting of one carbon atom and two oxygen atoms. ... Carbon Monoxide (CO) is a chemical compound which contains one carbon atom and one oxygen atom and is also a colourless and odourless gas. Unlike CO2, it is entirely human-made and is not naturally present in the atmosphere.
Explanation:
Answer: You don give any of the options but an atom of oxygen can be written as O
Explanation:
Answer:
D
Explanation:
add all the know sides 8+8+3+5=24
perimeter of half a semicircle=circumference of half a semicircle
if circle is C=π×d
than semi C=1/2×d×π
C=½×4×π
C=2pi
so 24+2pi
Answer: 1. 5 feet
2. the product will be greater than the fraction and less than the mixed number.
Explanation:
1. Since Nancy needs 4 lengths of fabric that are each 7¾ feet. That means the total length will be:
= 7¾ × 4
= 31/4 × 4
= 31 feet
Since she already has a 36 foot bolt, the number of feet that will be left will be: = 36 - 31 = 5 feet
2. Since the question is about a fraction less than 1 multiplied by a mix number. Let's say the fraction less than 1 is ½ and the mixed number is 2½. Let's multiply them together. This will be:
= ½ × 2½
= ½ × 5/2
= 5/4
= 1 ¼
Base on this calculation, the correct answer is that the product will be greater than the fraction but less than the mixed number.
3. To solve this question, we need to convert 1 ⅔ hours to minutes. Since 60 minutes = 1 hour, 1⅔ hours = 1 ⅔ × 60 minutes = 5/3 × 60 = 100 minutes
Therefore, the number of minutes played before power went out will be:
= 3/4 × 100 minutes
= 75 minutes
