Answer:
1.64 ml
Step-by-step explanation:
2.05 + 6.15 = 8.2
8.2 / 5 = 1.64
We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
Answer: 232
Step-by-step explanation:
12÷4(9-6)×24+4^2
12÷4×3×24+4^2
12÷4×3×24+16
216+16
232
3*10^-1=3*0.1=0.3
800*0.3=240
the number in scientific notation is 2.4*10^2
