Answer:
He have 43 bills of 10 and 13 bills of 5
Step-by-step explanation:
5x + 10y = 495
x + y = 56
Isolate x:
x = 56 - y
Substitute in the first equation:
5(56 - y) +10y = 495
280 -5y +10 y = 495
5y = 495 -280
5y = 215
y = 215/5
y= 43
Now substitute the value of y to find x:
x = 56 - y
x = 56 - 43
x = 13
Answer:
Step-by-step explanation:
first, 4l=2 x π x radius............................ eqn 1
next, find the value for the radius, r using
Area of a circle=πx radius squared
61.6=3.142 x r x r
61.6÷3.142=r x r
r x r= 19.6
r=4.43
then substitute the value of r in eqn 1
4l=2 x 3.142 x 4.43
4L=27.83812
L= 27.83812÷4
L≈6.96
area of a square = L x L
=6.96 x 6.96= 48.43
