Answer:
46euros
Step-by-step explanation:
Formula- I=P*R/100*T
P=principal amount R=rate T=time
Compute the values given in the question to this formula
So, it would be-
I= 500*0.023*4
I= 46euros
And that's all!

If my answer helped please mark me as brainliest thank you and have a great day!
8.9
The equation for the grain size is expressed as the equality:
Nm(M/100)^2 = 2^(n-1)
where
Nm = number of grains per square inch at magnification M.
M = Magnification
n = ASTM grain size number
Let's solve for n, then substitute the known values and calculate.
Nm(M/100)^2 = 2^(n-1)
log(Nm(M/100)^2) = log(2^(n-1))
log(Nm) + 2*log(M/100) = (n-1) * log(2)
(log(Nm) + 2*log(M/100))/log(2) = n-1
(log(Nm) + 2*log(M/100))/log(2) + 1 = n
(log(33) + 2*log(270/100))/log(2) + 1 = n
(1.51851394 + 2*0.431363764)/0.301029996 + 1 = n
(1.51851394 + 0.862727528)/0.301029996 + 1 = n
2.381241468/0.301029996 + 1 = n
7.910312934 + 1 = n
8.910312934 = n
So the ASTM grain size number is 8.9
If you want to calculate the number of grains per square inch, you'd use the
same formula with M equal to 1. So:
Nm(M/100)^2 = 2^(n-1)
Nm(1/100)^2 = 2^(8.9-1)
Nm(1/10000) = 2^7.9
Nm(1/10000) = 238.8564458
Nm = 2388564.458
Or about 2,400,000 grains per square inch.
Answer:
4
Step-by-step explanation:
We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:
1. set the equation 4x+3=19
2. solve for x
4x+3-3=19-3
This is used to solve for x
3. 4x=16 is found
4. if 4x=16, we divide 16/4 and get 4!
That's your answer hope it helped!
