Total amount of paper ÷ width of the strips = amount of strips
9 ÷ 0.4 = 22.5 strips
*Note: 2/5 is the same as 0.4 in decimal form
Step-by-step explanation:
rules of the logarithm :
e.g.
log(a×b) = log(a) + log(b)
log10(9) = log10(3×3) = log10(3) + log10(3) =
= 0.4771 + 0.4771 = 0.9542
log10(49) = log10(7×7) = log10(7) + log10(7) =
= 0.8451 + 0.8451 = 1.6902
5.8 to 1 decimal place would be 0.58
Answer: x = 12
Step-by-step explanation:
5(x-1)+3x=7(x+1)
5x - 5 + 3x = 7x + 7
8x - 5 = 7x + 7
x - 5 = 7
x = 12
Y-int , you need to replace x with 0 and solve for y. X-int , you need to replace y with 0 and solve for x.
