Answer : The temperature in degree Celsius is,
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
As we are given the temperature in Fahrenheit is, 451
Now we have to determine the temperature in degree Celsius.
Therefore, the temperature in degree Celsius is,
Answer:
Boron
Explanation:
First, locate the metalloids on the periodic table. (First picture) The metalloids are in the yellow section. Next, remember that the group your element is in determines its valence electrons. For example, group 17/7A has 7 valence electrons. Look at the group numbers above each column on the periodic table to find out which metalloid is the answer. In this case, we need to look at 13/3A since we know that this metalloid has three valence electrons. Not all periodic tables will be labeled with the 3A part, so remember that groups 13 and over have the amount of valence electrons after you take out the one in front. For example, group 16 has 6 valence electrons because I removed the one in front of it. Now your options should be limited down to boron because we know that it is in the yellow section in group 13.
About 46.1 pounds of apple would be needed per day of the trip.
I managed to extract the complete scenario from the attached image.
The trip is made up of 4 men and 3 women, making a total of 7 people.
Everyone has become accustomed to 1500 calories per day.
The total calories needed per day for 7 persons = 1500 x 7
= 10,500 calories
189 g of apple has only 95 calories, what g of apple will produce 10,500 calories?
= 10,500 x 189/95 = 20,889.67 g of apple
From conversion:
1 g = 0.00220462 pounds
20,889.67 g = 20,889.67 x 0.00220462
= 46.1 pounds of apple
