Jen is twelve years old and her mom is 38. 38 plus 12 is 50
Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2
<em>503 / 100</em>
<em>Convert the mixed number 5
3
100 into an improper fraction first by multiplying the denominator (
100
) by the whole number part (
5
) and add the numerator (
3
) to get the new numerator. Place the new numerator (
503
) over the old denominator (
100
)
. 503
/100

<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
Square root of x^2 is x
square root of 144 is 12
(x-12) (x+12)
x=12 or x= -12
