Answer:
Step-by-step explanation:
The equations can be written as ...
y = 350 -x . . . . . . . . total number of people
4x +2y = 1100 . . . . . admission fees collected
Substituting for y, we have ...
4x +2(350 -x) = 1100
2x = 400 . . . . . . . . . . . . subtract 700, collect terms
x = 200
y = 350 -200 = 150
150 children and 200 adults attended the fair.
8 times 9 divided by 2 the answer is 36
Area of a triangle: (1/2)bh, where b = base and h = height
(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11
Answer:
dI/dt= -0,000127 A/s
Step-by-step explanation:
From Ohm's Law we have V = IR . deriving on both sides of equality
dV/dt = dI/dt R + I dR/dt . clearing, dI/dt = 1/R (dV/dt - I dR/dt)
replacing by the values of the statement
dI/dt = 1/400Ω (-0,05 V/s - 0,02 A 0,04Ω/s) . making calculations
dI/dt = -0,0508V/s / 400Ω = -0,000127 V/sΩ. simplifying the units
dI/dt = -0,000127 A/s
When we add 82.545 and 128.580 we get a total of 211.125, now the closest number to the answer is B. 211.125
<h3>Addition of Numbers</h3>
Given Data
Number one = 82.545
Number two = 128.580
Total Number = 82.545 + 128.580
Total Number = 211.125
