The answer is in the image
The total nom of code that can be used is equal to 5+3 = 8
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
Area of rectangle= L*b
here,
L=12.4 cm
b= 8.8 cm
A= L*b
= 12.4 * 8.8 = 109.12 cm^2
Volume of rectangular prism=length * width * height
Given,
length=3/8cm
breadth=5/8cm
height=7/8cm
therefore volume=(3/8)*(5/8)*(7/8)
=105/512 cm3
We can put the numbers in ascending order-
36, 38, 39, 39, 40, 47, 48, 51
Range=max-min
=51-36
=15
It will provide an instant answer!
