Answer:
66/54
Step-by-step explanation:
Answer:
75% because the ratio is 1:4 so the probability of the next being minestrone is high.
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:
which would be 1 third times 3.14 times 6 squared times 33
Step-by-step explanation:
okay so your dealing with a cone and a hemisphere. so what you would do is the cone equation is 
multiplied by 
multiplied by the radius squared times the height so what u would o is plug in the things you know .
Answer:
9 tshirts
Step-by-step explanation:
Money he had for t shirts= $75
Cost of shipping= $3
Money left for t shirts= $75-$3=$72
Cost of 1 t shirt= $8
We can find the answer with two ways:
1st way: tshirts of $8=1
tshirts of $72=72/8
=$9
2nd way: Cost ($) 8 72
T shirts 1 x
8/1=72/x
by cross multiply
x=72/8
x=9
