Answer:
yes
Step-by-step explanation:
Here's a chart that should help explain things a bit better.
Answer:
18 inches and 57 inches
Step-by-step explanation:
The diameter and the circumference of a circle are proportionate to each other.
The circumference of a circle will always be the diameter times . We know this because the circumference of a circle is represented as
Since the diameter is twice the radius, we multiply the radius by 2 - there's already a in this equation, so .
1st option: , this is close to 57 so it's reasonable.
2nd option: , this isn't close to 28 at all.
3rd option: , this isn't close to 80 at all.
So the 1st option is reasonable.
Hope this helped!
Given :
- In a neutral atom that has an atomic mass of 22 and atomic number of 12.
To Find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> that</u><u>,</u>
- n(neutrons) + n(protons) = A
- n(neutrons) + 12 = 2 2
- n(neutrons) = 22-12
- n(neutrons) = 10
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is </u><u>1</u><u>0</u><u>.</u>
To find the slope, take -7.5 - 10 over 5 - 0 and solve. Simplify for your slope. Then, do y=(slope)x-10.
Answer:
90000 solar cells.
Step-by-step explanation:
At North America Solar Challenge, if there are 810 solar cars arranged in 9 rows, then there is solar cars in each row.
Now, given that teams use up to 1,000 solar cells to design and build solar cars for a race.
Therefore, each solar car contains 1000 solar cells to design.
Hence, in 90 solar cars in each row, there will be (1000 × 90) = 90000 solar cells. (Answer)
