9x^2-4x-3 and x=-2
= 9*(-2)^2 - 4*-2 - 3
= (9*4)+8-3
= 36+8-3
= 44-3
=41
27%
65/245 = 0.2653
Multiply 0.2653 by 100 to get the percentage = 26.53%
Rounding to the nearest whole percent = 27%
Answer:
h = (m/4 - as)/s
Step-by-step explanation:
s = m / 4(a+h)
(a+h) · s = m/4 ><em>multiplied </em><em>(a+h)</em><em> on both side</em>
as + hs = m/4 ><em>distributed the </em><em>s</em><em> to </em><em>(a+h)</em>
hs = m/4 - as ><em>subtracted </em><em>as</em><em> on both side</em>
h = (m/4 - as)/s<em> >divided </em><em>s</em><em> on both side</em>

Given data:
The given biology percentage is B=40%.
The given chemistry percentage is C=24%.
The percenage of earth science as compare to physics is E=P+4%.
The expresion for the sum of all subjects is,
B+C+E+P=100%
40%+24%+E+P=100%
E+P=36%.............................(I)
Substitute given value in the above expression.
P+4%+P=36%
2P=32%
P=16%
The nummber of students assigned earth science is,
E=16%+4%
=20%
Thus, the percentage of the students assigned to the physics subject is 16%.
Answer:
65
Step-by-step explanation:
remember a TRIANGLE always have a 180 degrees total angle,
so 45+70=115
180-115=65
