Yes you did, you count up all the decimal spaces in all (which is 4 in this case) and put that amount of decimal spaces in the product.
Answer:
0.88
Step-by-step explanation:
-5.37 + 8.14 - 1.89
-5.37 + 6.25
= 0.88
So you have some initial amount x and we want to know how long it will take with compound interest to triple our original amount x (so 3x). The equation sets up like 3x(the amount we want)= x(original amount) times 1.062(the interest increase)^t So 3x=x(1.062)^t where t is the amount of years. When you divide both sides by x it cancels out and you end up with 3=1.062^t. Take the natural log of both sides. Ln(3) = Ln(1.062^t) and the t being an exponent can come in front of the the natural log. Ln(3) = t(Ln(1.062)) Divide both sides by (Ln(1.062)),. Ln(3)/Ln(1.062)=t. And you should just plug that into a calculator to find t.
I'm sure the answer is 2 and 1/4. it has to be a positive and the marker is over 2 so...yeah

Answer:
Will’s Wrapping Company needs 9,980 mm^2 of paper to wrap the chocolate bar.
Step-by-step explanation:
The formula for the area of a rectangular prism can be written ...
A = 2(LW +H(L+W))
A = 2(90·50 +3.5(90 +50)) = 2(4500 +3.5(140)) = 2(4990)
A = 9980 . . . square millimeters
